Yozakura Family

The Yozakura Family^note Clockwise from the top: Kyoichiro, Nanao, Kengo, Mutsumi, Taiyo, Shin, Shinzo, Futaba

A superspy family consisting of some of the finest espionage agents in the world and the heroes of the story. Their incredible talent for all things sneaky is only matched by their sheer quirkiness. Taiyo marries into the family to protect himself and Mutsumi from Kyoichiro, kickstarting the events of the plot.

---

• Acquired Poison Immunity: Part of their Training from Hell involves regularly adding trace amounts of deadly poisons like cyanide into their food to develop an immunity to toxins in the field. This happens enough that none of the Yozakuras even flinch when fed this poisoned food anymore, which proves essential when facing Poisoned Weapons in the field.
• Anti-Hero:
  • While most of them are at least well-meaning people, it's made clear from the beginning that they're mercenaries and Household Names in the criminal underworld. It's implied that all of them have killed in the past and the government goes to them for jobs beyond the scope of law enforcement or even their own covert operations division, Hinagiku. Taiyo goes so far as to tell Hanawa the Courier that he doesn't care what happens to the rest of the world because of his actions, he's only fighting to protect Mutsumi.
  • Kyoichiro gleefully pulls out various Yozakura weapons and torture tools to torment Taiyo, all but stating that the Jack Bauer Interrogation Technique has been a staple of the family for generations.
• Badass Family: A family of six of the greatest spies in the world and their clan head, Mutsumi. All of them can wipe out criminal outposts on their lonesome and are super talented in one or more areas. Taiyo is training to join their ranks so he can protect Mutsumi and can already handle most mooks on his lonesome.
• Bunny-Ears Lawyer: Their talents are rivaled by their oddball personalities. For instance, Kyoichiro is a severe Knight Templar Big Brother. Shinzo is a Nervous Wreck until you give him a gun. Shion is a Gamer Chick Challenge Seeker who turns computer systems into video games for her to beat just because. Kengo is obsessed with making life interesting and will make a mission harder just to get a kick out of it.
• Child Prodigy/Teen Genius: The Yozakuras' genes ensure that all of them with be extremely talented in one area and have superhuman physiques to go with it, as shown with Shinzo's marksmanship, Kengo's disguise artistry, and Nanao's medical prowess. All of them were trusted with highly secretive and dangerous missions since they were in diapers.
• Dramatic Dislocation: Parodied. To use an Air Vent Escape, the Yozakuras are all trained to be able to dislocate and relocate their bones as needed to fit through narrow passageways, doing so with utmost ease and minimal pain. Taiyo is not nearly as well-trained and recoils in agony when he has to do it himself.
• Exotic Eye Designs: Whenever the Yozakuras are using their full abilities through their Blooming, their eyes glow and gain a sakura flower pattern in their irises.
• Famed In-Story: They're a household name in the criminal underworld as the most powerful spy family around. Every member is individually a monster, but together they're nigh-invincible.
• Fiction 500: They're wealthy enough to have a mansion, ridiculously advanced spy tools, and have their estate guarded by a massive array of booby traps and drones. None of these things seem to dent their bottom line and their living room is filled with bags of cash from payments and missions. Sound drama clips specify that in addition to mission pay, the Yozakuras maintain a vast network of investments that Mutsumi manages to ensure the Yozakuras' continued financial stability. In the same conversation, Mutsumi mentions buying planes for the family with the same tone as someone listing stuff for their grocery list.
• Glowing Eyes of Doom: When the Yozakuras are using their Blooming, their eyes glow bright pink and gain a sakura flower pattern. If you see this as their enemy, run. More humorously, the light from their eyes is bright enough to act like a car's high beams.
• Hairstyle Inertia: All of the Yozakuras have worn the same hairstyle since they were toddlers. The only noticeable difference is Mutsumi's white streak.
• Heir Club for Men: Inverted. All of the family heads seen thus far in the series: Mutsumi, Rei, and Keiko, are women, implying that only women are capable of siring the next generation of Yozakuras and thus taking the position as family head. Indeed, the origin of the Yozakuras' extraordinary abilities can be traced back to Tsubomi Yozakura, the first "head" whose miraculous abilities made her a commodity used by her father Asa. This distinction makes it even more shocking when Kyoichiro discovers that Alpha also has the potential to be a clan head.
• Meaningful Name: The Yozakura name refers to cherry blossoms, which are associated with renewal, fleeting life, and the spring, fitting the deadly and highly dangerous nature of their profession.
• Superhero Speciation: All of the Yozakuras receive the same training to excel at everything spy-related, from sneaking around to hacking to combat. But each of the Yozakuras has their own specialty, such as Futaba's martial arts and Shinzo's weapons mastery. This is taken even further with their Blooming abilities, which pushes the power of their Superpowerful Genetics to the limit to unlock a unique superpower for them.
• Super-Senses: All of the Yozakuras have extremely fine senses. Shinzo says he can hear any kind, whether it's silenced or shot from a sniper rifle from incredible distances. Their senses are so sharp that they sometimes experienced Sensory Overload when they were younger, forcing the older siblings to subdue the younger ones. Taiyo experiences this himself once Mutsumi injects him with her blood, briefly paralyzing him from the sheer amount of information he's experiencing. He later goes berserk after the fight because he can't handle all of that sensory input and is only subdued by Mutsumi's singing.
• Super-Strength: All of the Yozakuras have this to some degree, as shown by their training equipment including weights that are anywhere between 100 kg and 500 kg. Futaba throws people like ragdolls while Nanao can lift sixteen-wheelers with only moderate effort. Shinzo is also shown lifting enormously heavy weights and casually dual wields rocket launchers. The main subversion is Shion, who is far less physically inclined.
• Thou Shalt Not Kill: Downplayed. It's all but stated that the Yozakuras have killed before, but they certainly prefer to avoid it if possible, as they're spies by trade, not assassins. Though, given the creative array of torture tools Kyoichiro has at his disposal, Cold-Blooded Torture is definitely not off the table.
• Where Does He Get All Those Wonderful Toys?: They make them all in-house through their extreme talents. Shinzo's a master of firearms and trap setting, Shion is a programming wizard, Kengo is a Master of Disguise, and Nanao is a medical genius. Between them and their seemingly endless supply of wealth, they're never wanting for equipment.
• The Worf Effect: They're established as more or less unbeatable, especially when they're together, since Chapter 1. Even when Tanpopo develops Super Soldiers to match them, the Yozakuras still come out on top. Hence it's even more shocking when Momo handily trounces all of them in the span of a conversation between Taiyo and Kawashita.

10th Generation

Taiyo Yozakura neé Asano

Taiyo Asano

Voiced by: Reiji Kawashima (anime, vomic), Natsuki Hanae (Special Drama)

Taiyo was just like any other teenager until he lost his parents and little brother in a tragic car accident. Since then, he's been terrified of social interaction out of fear of losing people he cares about. The one exception is his Childhood Friend Mutsumi. He soon discovers that she is the heir to the Yozakura family of international superspies, and the only way to escape the wrath of her Knight Templar Big Brother is to marry her and become a spy himself.

---

• Amusing Injuries: The Yozakuras' Acquired Poison Immunity training turns a barrage of venomous bites and stings into this for Taiyo. He's left looking comically swollen from getting dozens of doses of venom from wasps, scorpions, and snakes, but is otherwise okay.
• Badass in Distress: Taiyo gets kidnapped on multiple occasions, usually to make him a bargaining chip for Mutsumi. He's also the target of numerous assassination attempts from would-be suitors who want to supplant him as Mutsumi's husband. Tanpopo purposefully leaves him in critical condition but not dead to force all the Yozakuras to gather at their mansion to guard him, allowing Tanpopo to swarm the place with their Hazakura-enhanced soldiers in hopes of wiping out the Yozakuras all at once.
• Badass Longcoat: Following the Time Skip, Taiyo's day-to-day spy wear has evolved from the Yozakura sweatshirt and pants to a dark, hooded longcoat that goes down to his ankles.
• Bad Liar: Taiyo has an awful poker face. When playing to lose a card game against Mutsumi so she can have the last soufflé, he makes incredibly exaggerated faces of joy and apprehension that make it easy for her to pick the wrong cards. Fortunately for Taiyo, Mutsumi is just as bad.
• Berserk Button: Taiyo is so devoted to Mutsumi that he cannot tolerate even light jokes implying he would cheat on her. Its also one of the few things that will actually get him angry at other members of the family. Kengo makes one joke about how Taiyo could use a disguise and the excuse of a mission to cheat as much as he wants...only to very quickly retract and apologize when Taiyo angrily asks him to repeat himself.
• Be Yourself: Taiyo tries multiple times to engineer perfect dates and outings for Mutsumi while keeping her safe, following tips he sees in magazines and what not. But he's always at his coolest when he's just being honest with himself and clearly expressing his feelings for her. It's in those moments that he manages to make her swoon even if he doesn't realize it.
• Big Brother Instinct:
  • The trauma of losing his younger brother makes him act irrationally when he hears that a little girl was going to be shipped off to "hell" as part of a human trafficking operation. He immediately rushes off to save her, even though it costs him his lead to rescue Mutsumi. Thankfully, said little girl happened to see the truck Mutsumi was being boarded into.
  • His brotherly instincts later extend to his younger brother-in-law, Nanao. After learning about Nanao's struggles to go to school and have a life away from the family business, Taiyo is moved to tears and takes it upon himself to be ready with a rifle to suppress Nanao's mutations whenever they happen.
    Taiyo: [pulls him into a Cooldown Hug] Your older brother here is gonna be right by your side.
• Body Horror:
  • Taiyo's back and left arm bulge and spasm like an enormous cancer tumor after Kawashita injects the blood of the first Yozakura head into him. The tumor-like growths spread to his neck and head as Kawashita tries to Mind Rape him with the dark secrets of the Yozakura family.
  • Later on, Taiyo begins suffering from lethargy and Power Incontinence in the days after the fight. When he goes back home to rest, his flesh and hair begin twisting into the shape of sakura flowers until he's able to suppress the mutation with Tsubomi's advice.
• Boring, but Practical: Taiyo's Blooming is referred to as this. It lacks any kind of special tricks or gimmicks like Kengo's Empathy or Ban's Passage, simply toughening Taiyo's body to the point that he becomes bulletproof and resists even the mutated Kawashita's attacks. But it also makes him an ideal bodyguard for Mutsumi and it can be used in tandem with the other Yozakuras rather easily, such as Kyoichiro using him as a human bullet to bust through Kawashita's defenses. A bounty hunter following the Time Skip describes the Taiyo that has better honed his Blooming as his entire body being a weapon.
• But for Me, It Was Tuesday: A benign version. When talking with Lando via video chat and discovering he was one of the children he saved in the middle of doing another mission three years ago, he doesn't think was anything special. However, this encounter of Taiyo being the first adult to show him genuine kindness had a huge impact on Lando who became his fanboy ever since.
• Butt-Monkey: Poor Taiyo is on the receiving end of most of the story's slapstick, whether it's getting bitten and stung by countless poisonous insects, getting stripped naked in public by Sui, or just getting the snot beaten out of him by Kyoichiro.
• Characterization Marches On: Taiyo is initially depicted as cripplingly withdrawn and dour out of fear of getting close to anyone again after losing his family. He loses this completely a few chapters later, and the story shifts to focus on his Determinator mindset, his Nice Guy tendencies, and the humor that comes with becoming Properly Paranoid.
  • Justified, due to both marrying into Yozakura family and making protecting Mutsumi his priority (alongside the training and torture (from Kyoichiro) near literally beat the fear and dourness right out of him.
• Charles Atlas Superpower: After putting himself through Training from Hell to protect Mutsumi, he thinks nothing of wearing a 100 kg shirt, can easily catch an oncoming baseball without even looking at it, and casually stops a tubby student from falling down the stairs with a single hand. Mutsumi lampshades how he's become nearly superhuman through his efforts and warns him not to show off too much, lest people get suspicious. As he continues his training, he starts doing pushups with a 500 kg weight on his back.
• Color-Coded for Your Convenience: His red hair and eyes distinguish him from the differently colored members of the Yozakura family.
• Confusion Fu: Aside from his dogged determination, Taiyo's greatest strength is his willingness to learn from others and incorporate their moves to throw his opponents off guard. He uses the gadgets and moves of all of his siblings to gain an advantage in combat. Disarm his lightning gun and he'll pull out one of Shinzo's knifes. Knock away the knife and he'll use Futaba's martial arts. Pull out a gun and he'll destroy it with Kyoichiro's Steel Spider. He later uses the Hinagiku's Stepping on Flowers to catch Kurogao off guard, performing a good enough imitation to outmaneuver him and successfully defeat the otherwise superior spy.
• Contortionist: After activating his Profuse Blooming of 10,000 Flowers for the first time, Taiyo's body becomes saturated with someinine. His bones and muscles become pliable enough that Futaba can fold him in half without him suffering any discomfort.
• Cool Big Bro: Taiyo dotes on Nanao after learning about the latter's complex about fitting in and having a normal social life outside of the spy world, going out of his way to ensure that Nanao's hulking form remains a secret. He's even willing to get his hand impaled if it means stopping Nanao from making a hasty decision to eliminate his School Mode entirely.
• Cooldown Hug: He combines this with Affectionate Gesture to the Head to calm down a panicking Nanao, who had all but given up on his chances of a normal school life.
• Conditioned to Accept Horror: Played for Laughs. The Yozakuras are so hard on Taiyo that he's desensitized to most everyday thrills. For instance, when he and Mutsumi ride a roller coaster, he ends up falling asleep because it's relaxing compared to his daily training and frequent missions.
• Conveniently Orphaned: Taiyo lost his parents and little brother in a car accident, allowing him to be married into the Yozakura family without something like pesky parental consent in the way.
• Cowardly Lion:
  • Taiyo is easily spooked and social interaction leaves him hyperventilating at the beginning. But when it comes to protecting Mutsumi, he won't hesitate to grab Razor Wire or even jump off a building to his death. He toughens up considerably thanks to the Yozakura's training, but it's mainly because everything seems less scary after the hell he went through. For instance, it's a lot easier to scale down a building when you know there aren't spikes at the bottom.
  • When kidnapped from home and handcuffed to a chair, he quickly freaks out about it before calming and freeing himself. After that, a gun is put to his head and he manages to instantly react to disarm the guy despite his fear.
  • Even after gaining the physique of a Yozakura through Mutsumi's blood, Taiyo cries Tears of Fear while fleeing Kenji's extremely muscular parents, though this may have easily been a feint to draw them away so Shion could free Kenji, as Taiyo turns around and ties them up as soon as Kenji is freed.
• Curtains Match the Windows: He has red hair and eyes.
• Determinator: Taiyo will do anything to protect Mutsumi, throwing himself off a building after he realizes he's been tagged with a bomb, putting himself through Training from Hell, and suffering through one assassination attempt after another to keep her safe.
• Doting Parent: Following a five-year Time Skip, Taiyo becomes the proud father of two four-year-old twins, Alpha and Hifumi. He's doting on the both of them and breaks down into Inelegant Blubbering because of how proud he is of Alpha for being so mature and responsible.
• The Dreaded: Played for Laughs. After the Time Skip he has this reputation in the spy community. Because he's the Only Sane Man in a family like the Yozakuras. Since the spies who don't know him personally don't think it's possible to be sane in that family, they think he's actually the scariest of them all. They also believe that the reason no one has evidence of his dirty business is because he kills off any witnesses.
• Empowered Badass Normal: While he's trained himself to be practically superhuman himself, he's always lagged behind the innate superhuman prowess of the Yozakuras. Then Mutsumi injects him with a sample of her blood in a desperate attempt to keep him alive after he's critically injured, granting him the same physical abilities and Super-Senses as the other Yozakuras. His strength in particular grows to the point that he's able to throw off Shinzo and Nanao at the same time. His Finger Poke of Doom also buries Sosuke in the wall of the school and shakes the entire building. After receiving Tsubomi's blood, Taiyo's body is converted into something resembling pure someinine, granting him inhuman flexibility and increasing his strength enough to crack even Kyoichiro's strongest defenses while using his Profuse Blooming of 10,000 Flowers. More importantly, he's able to hurt Momo, who'd otherwise disperse into flower petals upon being struck.
• Establishing Character Moment: Taiyo is introduced sitting glumly at a desk and constantly shuddering as his classmates try to get him to hang out with them. He begins to froth at the mouth soon after he declines their invitations and only calms down when Mutsumi offers him lunch and teases him.
• Even the Guys Want Him: The male Tsukiyo Hoshifuru flirts with him. It wouldn't really be surprising due to Hoshifuru's tendency to flirt with everyone, but the end of Mission 34 has him admit that he wasn't being facetious about his attraction at all. Alexandryu also calls him a pure, good boy... albeit one who would be a boring boyfriend without a single scandal to his name.
• Exotic Eye Designs: After being injected with Mutsumi's blood and gaining the physical abilities of the Yozakuras, Taiyo's right eye displays the shape of a sakura flower whenever he's tapping into his new powers.
• Famed In-Story: Taiyo immediately becomes famous in the criminal underworld after Kyoichiro leaks his marriage to Mutsumi in an attempt to kill him. His various misadventures bring him both good and bad press, but he cements a reputation for himself among spies as a rising rookie who has proven himself time and again through his dogged determination and constant training.
• Family Theme Naming: After marrying into the Yozakuras, Taiyo is the fourth eldest son. "Yo" is homophonous to a Japanese word for "four".
• Fantastically Indifferent: Subverted. Despite all his training, Taiyo continues to be the Only Sane Man and reacts with alarm and surprise when encountering something truly weird, like buying bullets at a bubble tea shop or Nanao shrinking down to an unrecognizably small state. Double Subverted after the Time Skip, as Taiyo is perfectly okay with his four-year-old children jumping out of an airplane without a parachute because he knows Kyoichiro is looking out for them.
• Feels No Pain: Quickly subverted and Played for Laughs. Taiyo insists that Nanao didn't hurt him after he stops Nanao from injecting the permanent transformation vaccine even though the needle is sticking through his hand. Nanao himself is surprised until Taiyo asks him to take it out slowly.
• Fiery Redhead: Subverted. Taiyo has all the standard trappings of your Stock Shōnen Hero, including messy red hair, Idiot Hair, and a scar going down one eye, but he's meek and shy until he's pushed. Even after a confidence boost from a month of Training from Hell, he's still fairly dour and even-tempered.
• First-Name Basis: Taiyo and Mutsumi are on this with each other, showing how close they are even before their marriage given how Last-Name Basis is standard in Japan.
• Foil: Taiyo's personality contrasts numerous people inside and outside of the Yozakura Family.
  • Taiyo and Kyoichiro both love Mutsumi dearly and desire to be her greatest protector, but the latter's Big Brother Instinct has been warped by trauma into an unhealthy, possessive kind of love in which he desires to keep her in a Gilded Cage away from anyhting that can possible harm her. Taiyo, despite being even more traumatized by the loss of his entire family, is able to respect Mutsumi's desire for freedom, guarding her with similar zeal but also being an emotional confidant and companion in ways that Kyoichiro cannot.
  • Sui treats spywork as strictly a job and performs all of his tasks with almost comical levels of seriousness. He eschews emotion and admonishes Taiyo for his inexperience. Taiyo is the opposite, having gotten into the spy life for the sake of protecting his wife and new family, adhering to a strict Thou Shalt Not Kill rule, and reacting with incredible alarm at the spy antics around him.
  • Although they're the past and current patriarchs of the Yozakura family, Ban is loose-lipped, goofy, and fun-loving in contrast to Taiyo's Only Sane Man personality. They also led self-destructive lives before meaning their wives, but Ban's happy-go-lucky semi-retirement is jarring next to Taiyo's increasing and almost obsessive zeal in protecting Mutsumi. Even their Blooming abilities are polar opposites. Ban's "Passage" enhances his already incredible flexibility to allow him to freely warp and manipulate his body to get himself and his weapons in any position he desires, while Taiyo's "Hardening" causes his body to prepare to take an attack head-on, hardening his cells and softening his joints to absorb and nullify it.
• Friend to All Children: Due to losing his little brother Hikaru to a fatal car accident, Taiyo is protective of children and will rush to help them on instinct. Even if it means losing a potential lead to find Mutsumi, Taiyo can't help but try to save a young victim of human trafficking. Following the Time Skip, he's a full on Papa Wolf to his twin children, and once disregarded mission objectives to save a group of abused children before doubling back to complete his original mission.
• Good Scars, Evil Scars: He has a neat, slim scar going over his eye as a reminder of the car accident that killed his family.
• Grappling-Hook Pistol: Grappling hook belt, actually. His is designed by Shinzo to handle 500 kg and extend 50 m.
• Happily Married: Despite the less than ideal circumstances of their marriage, Taiyo and Mutsumi are legitimately in love and happy together, to the point that both would be willing to give their lives up for the other without a second thought. They're so happily married that by the Time Skip, Mutsumi has founded an online cult venerating her love for him. Rather than being creeped out, Taiyo just takes it as another indication of how much she cares.
• Hard Work Hardly Works: Zigzagged. Taiyo puts himself through hell to train and become strong enough to protect Mutsumi. His single-minded devotion to this goal is what gets him to work to the point of collapse, but at the same time he clears every trap in the Yozakura mansion in a single month. But even then, it isn't enough for him to handle more experienced spies and he quickly gets his ass kicked. Kyoichiro even admits that he's impressed by Taiyo's progress, but that makes Taiyo still lower than third-rate. In all fairness, this is more chalked up to Taiyo being far less experienced then the spies around him (some whom have been on missions since they were six years old).
• Heroes Prefer Swords: As the limits of Yae become more and more pronounced, Shinzo upgrades it to be able to produce a sword for whenever the lightning fails to work. From then on, Taiyo begins incorporating Yozakura-style swordsmanship into his repertoire.
• Heroic RRoD:
  • After being turned into an Empowered Badass Normal, his body has to get used to its new Super-Senses and physical strength, leaving him so wracked with pain that he's completely unable to move for an entire week. Even after he manages to return to school, he's gritting through the pain all the while. It subsides completely a few weeks later, during which time Mutsumi tries and fails repeatedly to create a manju bun to treat him, only finishing it with his help.
  • After showcasing his new Super Mode following the Time Skip, Taiyo suffers a fever from the strain of using it even for a few minutes.
• Heroic Self-Deprecation: Taiyo doesn't have a high opinion of himself, telling Mutsumi that he's selfish for marrying solely to protect her without any thought to her feelings.
• Idiot Hair: One strand of Taiyo's hair sticks up and curls around.
• Impaled Palm: Suffers this when he stops Nanao from injecting the stabilization vaccine, showing just how strong Nanao is when the force he uses to precisely inject the medicine goes through Taiyo's palm.
• Implacable Man: Post-Time Skip, Taiyo's mastery of his Blooming has grown to the point that he can walk straight through bladed prostheses and have them shatter against his skin and clothes. Even a blow from Alexandryu, who could crush Tsubomi's monsters with his bare hands, fails to make Taiyo so much as flinch when he throws himself between Alexandryu and the fleeing Yozakuras.
• Ironic Name: Taiyo's name translates to "morning sun". Taiyo himself is anything but sunny at the start of the story: a shy, meek recluse who struggles to interact with people without falling unconscious.
• It's All My Fault: Taiyo blames himself for his current predicament and is constantly apologizing to people for troubling them, ignoring how his Ax-Crazy brother-in-law is the one who started this whole mess.
• Jack of All Stats: Taiyo lacks the specialties of any of his siblings, but he makes a point of learning as much as he can from each of them. As a result, he's able to blend all of them into his personal Confusion Fu style that lets him take far more experienced foes by surprise.
• Lightning Gun:
  • Kyoichiro gives Taiyo a gun that shoots lightning instead of bullets that can be used as a direct attack, disable enemy electronics, and destroy incoming projectiles by frying them before going into for hand-to-hand. Even when he does use it to injure someone, he usually fires it at near point-blank range even though it can hit things farther away due to the potential for collateral damage. That said, unless it's being played for drama, the worst the gun does to people is Harmless Electrocution.
  • It's later revealed that the gun is called "Yae" and was personally designed by Shinzo. It's later modified to allow a sword to sprout from the barrel for close combat should Taiyo's opponent have a means of nullifying Yae's electricity. After the Time Skip, Taiyo's abilities have grown to the point that he can use Yae to vaporize the top half of an office building.
• Men Can't Keep House: Inverted. In stark contrast to his brother-in-law Kengo, Taiyo is neat and organized. While working undercover, he makes a surprisingly good bellboy and train attendant, leaving rooms spotless to the point of making the ceiling as reflective as a polished mirror.
• Muscles Are Meaningless:
  • Taiyo doesn't get noticeably brawnier after his Training from Hell, but it's obvious that he's nearly superhumanly strong when he can stop people from falling down the stairs with a single hand and toss a baseball across an entire field with pinpoint precision.
  • Later on, he starts showing more muscle tone during a bit of Workout Fanservice.
• My Suit Is Also Super: He gets a set of the Yozakura's loungewear for infiltration missions that's bulletproof, blade resistant, super lightweight, and machine-washable.
• New Job as the Plot Demands: Several of his assignments require him to go undercover, so he ends up doing everything from being a bellboy to working as a train attendant. He's noted to be surprisingly good at his work and gives it his all even though it's not what he's supposed to be doing there.
• Nice Guy: Even after becoming a spy, he remains stubbornly moral with a Thou Shalt Not Kill rule that even applies to people trying to kill him. He's always nice and supportive of friends and family and generally tries to see the best in people (even his Knight Templar Big Brother Kyoichiro and creeps like Sosuke). Most other spies are taken aback by just how nice he is, and he manages to attract a number of admirers because of how unusual it is for a spy to be so kind.
• Ocular Gushers: Hearing the full story of Nanao's mutations and his desire to go to school moves Taiyo to cry rivers of tears before promising to do everything in his power to keep Nanao in school. He does the same after listening to his son Alpha discuss wanting to be a normal upright citizen and ensure his sister won't put herself in danger.
• Noiseless Walker: Taiyo learns to do this like the rest of the Yozakuras, spooking his classmates who wonder if he's a ninja.
• Offscreen Moment of Awesome: As the series goes on, Taiyo is called a "Super Rookie" by various spy magazines for his increasing number of successful missions that the reader never gets to see. Meanwhile, several chapters open with Taiyo recovering from one of these missions.
• One Head Taller: Post-training, Taiyo tends to stand one head taller than his wife, Mutsumi.
• Only Sane Man: Due to not being born into a family of superspies, Taiyo reacts appropriately to the insane antics he gets into. Taiyo doesn't become Fantastically Indifferent even after acclimating to the Yozakura lifestyle, though he does gain his own quirks by being Properly Paranoid and his Sickeningly Sweethearts with Mutsumi.
  Mutsumi: [after telling Taiyo about her family's work] Ahh, it was such a pain to keep quiet all these years. I feel a weight off my shoulders. I'll go make some tea.
  Taiyo: Whoa, whoa, whoa, whoa!!! Spies?! What? What the heck?! Don't just say that like your family runs a grocery store!
  Mutsumi: Isn't it kind of the same thing? Instead of handling radishes and eggplants we handle guns and intel.
  Taiyo: It's not the same thing!! It's different, right? Huh?! I can't tell anymore!
• Papa Wolf: Taiyo becomes a father after the Time Skip and is fiercely protective of his children. When Alpha and Hifumi are targeted by a bounty hunter named Hydra, Taiyo's first response is to make sure the twins are safe before throwing Yae into the man's chest to immobilize him. It doesn't take long after that for Taiyo to turn the fight into a Curb-Stomp Battle that he ends in one punch while warning Hydra and all of his associates to stay away from Alpha and Hifumi.
• Parents as People: Taiyo is a loving and doting father toward both of his children, but the nature of his work means that employment is inconsistent and highly dangerous. The secrecy of the spy industry means that Alpha has had to learn to keep many secrets from a young age, which has affected his ability to make friends on top of Alpha's issues with being isolated by his intelligence. Despite all this, both Alpha and Hifumi clearly adore him and retaliate against Kyoichiro for trying to bullying Taiyo.
• Personality Powers: Taiyo's Blooming, Hardening, represents his resolve to avoid killing others and shield others, especially his family, from harm. It's not flashy, complex, or especially fascinating, much like his own origins as an ordinary teenager prior to joining the Yozakura family. Lampshaded by Kawashita, who calls it the perfect power for a "pushover" like Taiyo.
• Positive Friend Influence: Taiyo's compassion, selflessness, and dogged determination gradually inspires all of the Yozakuras to be better.
  • Having a new little brother to mentor and protect gets Shinzo to control his nerves and be more reliable.
  • Shion loosens up around him and is able to show more of her kinder side.
  • Kengo considers Taiyo one of the few people whose intentions he doesn't have to question because of how Taiyo's kindness and tendency to wear his emotions on his sleeve .
  • Nanao learns to accept himself and adapt to circumstances rather than resigning to them.
  • Even Kyoichiro begins to move away from his Knight Templar Big Brother behavior and acts more like a Cool Big Bro to the other Yozakuras, trusting Taiyo despite his misgivings and giving Mutsumi more freedom.
• Power Dyes Your Hair: Taiyo his True Spring Blooming post-Time Skip. In this state, Taiyo's hair, skin, and clothes are all bleached white, which onlookers compare to having a bucket of white paint dumped on him.
• Power Incontinence: After Kawashita's defeat, Taiyo's powers go haywire at school, causing him to be in a constant state of Blooming and Super-Toughness. As a result, he has trouble moderating his Yozakura strength and his body is so hard that even a simple bump can severely damage his surroundings. He's also so tired and sluggish that he doesn't notice when he runs into things, to the point that he walks right through the door while running to class. This is later revealed to be the result of Kawashita injecting the first Yozakura head's blood and memories into his body.
• The Power of Love: Taiyo is willing to put himself through intense punishment out of his love for Mutsumi to the point of using drugs to forgo sleep and train as much as possible. He continues doing this until his body gives out and he collapses from exhaustion. Futaba even notes that Taiyo's love for Mutsumi is bordering on insanity for him to withstand all of this. Even so, the dedication his love gives him allows him to clear all of the Yozakura's traps in a single month when it took them years to do the same.
• Properly Paranoid: After becoming part of the Yozakura Family, everything and everyone begins to look suspicious to Taiyo. Given that Mutsumi is constantly being hounded by assassins, it's a valid concern. Also deconstructed, as even if his concerns are justified, it still makes him look like a weirdo and a creep in public, on top of making his date with Mutsumi awkward.
• Psychoactive Powers: The power of Yozakura blood grows with the emotions they're currently feeling. When Taiyo's emotions are all in disarray after Shirai tells him the true circumstances behind the deaths of his family, he's so enraged that all of his stats spike. However, if handled carelessly, the someinine will ravage the body, killing him within a few minutes. In addition, his intense passion sends him into a state akin to The Berserker, lowering his accuracy at the cost of the boost in physical stats.
• Rank Up: Following the Time Skip, Taiyo becomes a gold-rank spy like his siblings and has the prestige to match, becoming a respected name in the spy world.
• Razor Floss: Taiyo borrows wires from Kyoichiro's Steel Spider on numerous occasions to bind his foes and give himself an advantage.
• Rookie Red Ranger: As Mutsumi's husband, Taiyo is the current patriarch of the Yozakura family. However, his inexperience means that he's often getting pointers from his new siblings while leaving the actual leadership to Mutsumi. As the story goes on, his growing experience and laundry list of completed missions (on-screen and off) under his belt get him called a "Super Rookie" among spies, though he's still clearly outclassed by his siblings in most situations.
• Scars Are Forever: Taiyo has a scar running down one eye as a reminder of the car accident that claimed his family's life.
• Secret-Keeper:
  • Futaba entrusts him with the knowledge of her greatest fear: losing the people she cares about most no matter how strong she gets. She feels pathetic for her lack of confidence in her ability to protect people like her mother, but allows her siblings to believe she has a fear of ghosts to keep them from seeing the cracks in her perfect facade. Futaba lets Taiyo in on the secret because he's her brother-in-law and has earned her trust through his constant devotion to Mutsumi.
  • Kyoichiro also trusts Taiyo with a secret mission to retrieve Rei's body from Kawashita's lab, not telling any of the others so as to not upset them or throw off their game when the mission begins.
• Sheep in Sheep's Clothing: Invoked and discussed. When Alexandryu has too much Blackmail material for the Yozakuras to intervene in Shinzo's forcibly arranged marriage to Alexandryu's daughter, Katana, Taiyo is the only one that Alexandryu doesn't have any dirt on because Taiyo is too much of a Straight Man to have embarrassing secrets or hobbies. This makes him and his children, Alpha and Hifumi, the only ones capable of acting without facing social annihilation at Alexandryu's hand. Of course, the other spies in the room think his squeaky-clean image is a mask and believe he must be hiding something, spreading rumors that he's a psycho who murders anyone who could make him look bad.
• Shipper on Deck: Besides gratitude for his partial involvement in helping him fit into the Yozakura family, Taiyo is willing to help Nanao maintain his shrunken form at school because he notices that he is crushing on Rinne Kitasato.
• Shrinking Violet: Taiyo is so terrified of social interaction that he froths at the mouth and passes out after the shortest social exchanges. This is because he sees himself as a Doom Magnet and fears that he'll lose everyone he cares about. He mostly gets over it out of necessity after being married into the Yozakura family, but years of being a social recluse have left him a Socially Awkward Hero.
• Shut Up, Hannibal!: Hanawa tries to break Taiyo's fighting spirit by pointing out all the bad things that would happen because of the Yozakuras' disruption of his supply lines. Taiyo tells him that none of those things have anything to do with him and that he just wants his wife back.
  Hanawa: You probably thought you were doing something good. But have you given any thought to what would happen because you stopped it for several minutes? The unapproved wonder drug that was supposed to be delivered in a few days... the ransom that was supposed to be delivered in a few hours would not be paid. And the weapons and mercenaries that were a few weeks late that would have decided the outcome in a fight against a dictatorial regime. Your selfishness caused a lot of disruptions around the world...
  Taiyo: That has nothing to do with me. I never thought I was in the right. I don't even care if what you're doing is wrong. I just want... to get Mutsumi back!
• Sickeningly Sweethearts:
  • Downplayed. He's not quite as over-the-top in his affection for Mutsumi as Ban is for Keiko, but his declarations of affection are so passionate and strong that Shion rolls her eyes at how sickly sweet they are.
  • While Mutsumi helps Shion pick out clothes for a date, Shion finds herself put off by how extravagant Mutsumi's selections are. Shion tries to ask Taiyo to talk some sense into his wife, but he just goes along with everything Mutsumi picks because he enjoys seeing her happy like this.
  • In the Time Skip, he's completely unfazed about the fact Mutsumi started a cult of love dedicated to him and is touched by the notion. Nanao comments that Taiyo's blushing alone is abnormal enough a reaction.
• Single-Target Sexuality: Even after getting married, Taiyo shows no interest in the attention of any other females (or males) and remains very much faithful to Mutsumi.
• Sketchy Successor: The underworld specifically notes that Taiyo isn't a particularly exceptional spy aside from his dogged determination to improve his skills and protect Mutsumi. This weighs on him as he begins worrying about sullying the Yozakura name and whether or not he ought to be with Mutsumi.
• Sleepwalking: Develops a habit of this after Kyoichiro tries to force him to be able to fight while half-asleep.
• Socially Awkward Hero:
  • Taiyo used to be so socially withdrawn that he'd froth from the mouth and pass out when someone tried to speak with him. He improves to a more normal level after dealing with the Yozakuras for a month, but now suffers issues from his constant paranoia over guarding Mutsumi, his ingrained muscle memory making him do things like act as a Noiseless Walker when he doesn't mean to, and his inability to properly show his affection to Mutsumi in a way that doesn't embarrass either of them.
  • When he and Mutsumi are out on an impromptu date while undercover, he tries to compliment her based on advice he got from a magazine, only to say that she looks like she could do high kicks in her outfit. He immediately lampshades how terrible that pickup line was, but Mutsumi tries to respond as if it were a normal thing.
• Sole Survivor: Taiyo is the only survivor of the accident that killed his parents and little brother. Kurogao claims that he only survived because it wasn't an accident.
• Straight Man: Due to growing up in a normal family before marrying into the Yozakuras, Taiyo lacks most of the goofy quirks of his in-laws. He's typically the one to react normally to the bizarre antics they get up to, setting up many of the gags of the series. Taiyo's Straight Man status shakes a little as he gains quirks of his own, such as his Sickeningly Sweethearts routine with Mutsumi, but he still remains comparatively serious and normal compared to the likes of Kyoichiro.
• Super Mode: Post-Time Skip, Taiyo develops his abilities to the limit by unlocking his True Spring Blooming, the ultimate expression of his Hardening ability. It makes him simultaneously incredibly resilient and incredibly soft to absorb and repel nearly any attack. In this state, he's able to stop Alexandryu's diamond-crushing attacks without any resistance and bring Ryu to his knees with a single punch.
• Super-Reflexes: As part of his Training from Hell, he honed his reflexes to the point that he could dodge pieces of chalk thrown faster than the speed of sound.
• Super-Toughness: Taiyo's Yozakura Blooming ability, "Hardening", hardens his cells and softens his joints at the point of impact to completely absorb an attack. A bullet fired at him flattens as though it struck a brick wall after hitting his palm. While suffering from Power Incontinence after his fight with Kawashita, his body hardens to the point that he doesn't notice that he walked straight through a door. Following the Time Skip, his Blooming seems to have been upgraded to Nigh-Invulnerability, as he walks straight through bladed prostheses without any effort as they shatter against his skin and clothes.
• Takes One to Kill One: Kawashita injected Taiyo with Tsubomi Yozakura's blood in an attempt to poison him to death, Taiyo's body has become saturated with someinine that flower-like growths of crystallized someinine appear on his body when he taps into his Blooming. This means his bodily composition is extremely similar to the resurrected Yozakura heads. After Momo curb-stomped the Yozakuras, Kyoichiro has Nanao and Shinzo soak Steel Spider in the melted form of these flower growths to render the weapon capable of bypassing their ability to simply disperse into flower petals upon being struck. Kyoichiro later uses Taiyo in a Fastball Special to punch Momo, who'd otherwise simply phase through most attacks.
• Teach Me How To Fight: After having a nightmare of being powerless to stop Mutsumi from getting kidnapped, Taiyo goes to Futaba and asks her to help him become strong enough to protect Mutsumi. To his surprise, Futaba agrees, under the condition that he manage to survive living in Yozakura's highly booby-trapped mansion for one month.
• Tender Tears: Learning about Nanao's plight moves Taiyo to the point of Ocular Gushers and he swears to help Nanao stay in school no matter what.
• This Looks Like a Job for Aquaman: It's repeatedly pointed out that Taiyo's Hardening isn't especially useful in combat. Sure, he can take a hit, but that would only delay the inevitable against a superior opponent. But that also means Taiyo is the only one able to penetrate Kawashita's bunker and retrieve Rei Yozakura's body, as the crystallized someinine will detonate the minute the threads binding her are moved, killing anyone but Taiyo. Downplayed following the Time Skip as Taiyo is more capable of using the Nigh-Invulnerability of Hardening to essentially shrug off damage and hit incredibly hard.
• Thou Shall Not Kill: Taiyo is still haunted by the loss of his family and refuses to kill anyone if he can help it. This is noted to be an oddity of his in the spy world, as while they're not assassins, killing others to advance one's goals is hardly unheard of. That said, he's heavily tempted to break this rule of his when Kuroyuri reveals that Taiyo's family was murdered in an incident staged to look like an ordinary car accident. Later on, he decides to forgo this rule entirely in case of Tsubomi Yozakura, who wants to die and whose very existence is a threat to the Yozakuras.
• Took a Level in Badass:
  • Taiyo's skills as a spy gradually improve over the course of the story, slowly catching up to the other Yozakuras. He takes an enormous leap toward getting on their level when he recieves Mutsumi's blood to gain Yozakura superpowers of his own. After the Time Skip, he's a gold-rank spy who can crush another ex-gold-rank spy with one punch and a respected name in the spy world.
  • Taiyo's experience and maturity after the Time Skip is exemplified in his handling of the plan to stop the unwanted marriage between Shinzo and Katnaa. While the other Yozakuras are panicking over having their most embarrassing secrets revealed, Taiyo remains perfectly calm and serious the entire time. He instructs his children to help him with an Indy Ploy that goes off without a hitch. Once the ploy succeeds, Taiyo is in the perfect position to stop Alexandryu from retaliating with almost casual ease. Pre-Time Skip, Taiyo would likely be struggling and panicking with everyone else, but he makes it look easy, showing how he's grown into the role of family patriarch. He later demonstrates the ability to calmly parry bullets flying at him and Mutsumi with Yae and vaporizes half an office building at her command.
• Traumatic Superpower Awakening: Ban activates Taiyo's Blooming ability by shooting a bullet at Mutsumi, making Taiyo throw his arm into the line of fire to protect her. Ban explains that the Blooming ability varies from one member of the Yozakura family to the other, and he needed to evoke Taiyo's strongest feelings to force it out.
• Triple Shifter: Several chapters open with Taiyo exhausted from having to go to school during the day and doing super spy stuff at night. In "Dozing Off", Kyoichiro tries to force Taiyo to be able to stay awake at all times like him, but only succeeds in giving Taiyo a sleepwalking habit.
• Understanding Boyfriend: Despite having to join a dangerous underground world, Taiyo remains understanding and patient with Mutsumi. He trains hard to be someone who can protect her. Even Mutsumi creating merchandise and a cult around him doesn’t creep him out; he sees it as a loving sign of Mutsumi’s devotion to him.
• Used to Be More Social: Taiyo used to be an ordinary, outgoing kid who loved video games. But the trauma of losing his entire family in a single night from a fatal car accident has made him a recluse who struggles to interact with people. He begins to get over it thanks to being forced to live with the Yozakuras for a month.
• Violently Protective Girlfriend: Gender-inverted. Taiyo has to stop himself from hunting down people sexually harassing Mutsumi over the internet when they ask for things like her body measurements.
• The Worf Effect: Although he's far from the strongest or most skilled of the Yozakuras, he regularly gets his ass kicked to show off the competence of the newest antagonist. The cover of the fifth volume features Taiyo preparing to wollop Sosuke with an oversized mallet for taking photos of Mutsumi without her consent.
• You Are Already Dead: He's the victim of this after he and Shinzo defeat a spy doped up on Hazakura, as Tanpopo's mysterious agent somehow manages to shoot Taiyo several times in such a way that he only realizes it several seconds later. Only Shinzo's immediate first aid and Nanao's swift treatment save Taiyo's life, but even then he's left in critical condition.
• Your Size May Vary: Depending on the scene, Taiyo and Mutsumi may be nearly the same height, or Taiyo may be One Head Taller than her.

Mutsumi Yozakura

Mutsumi Yozakura

Voiced by: Kaede Hondo (anime, Special Drama), Yuka Iwahashi (vomic)

Taiyo's Childhood Friend. She's the tenth head of the Yozakura family of superspies, but was not born with innate powers or talents. Instead, she's the member of the family who has to marry and produce children to continue the line of superpowered spies.

---

• Absurdly Youthful Mother: Following a five-year Time Skip, Mutsumi becomes the mother of twins, Alpha and Hifumi, but looks barely any older than she did five years prior.
• A Child Shall Lead Them: Downplayed. Mutsumi is the second-youngest of the Yozakuras, but she was born without a Yozakura talent, designating her as the heir to pass down the Yozakura genes to the next generation. But she's already well-acquainted with the spy life and is skilled at housework, paperwork, and diplomacy, allowing her to comfortably slide into the role after her mother's death. However, she admits that after her father is revealed to be alive, she's unsure of where to go or what to do, as so much is unknown to her.
• Badass Boast: After a third-rate assassin tries to kill her with a bomb, injuring Taiyo in the process, Mutsumi immediately sics Goliath on the assassin while broadcasting a cold warning to him and anyone else coming after her.
  Mutsumi: [Goliath bursts through a steel wall] Take this to heart... this is what happens when you run afoul of the Yozakura family.
• Berserk Button:
  • She's pretty resigned to the idea that Taiyo might slip and end up dead at Kyoichiro or someone else's hand. However, if she actually sees you hurt him, her sweet gentle exterior will drop in favor of some intense Tranquil Fury.
  • Seeing Sosuke's phone filled with photos of her makes her do a complete 180 from sympathizing Nice Girl to telling Taiyo to shock him without a second thought.
• Brutal Honesty: Mutsumi has no problems speaking her mind without a filter, especially when it comes to her siblings. She calls Kyoichiro out on not having the guts to actually kill Taiyo out of fear of angering her, meaning that all of his death threats are Kyoichiro's attempts to maintain his self-image. Even as Kyoichiro is dangling Taiyo over a shark's mouth, she calls Kyoichiro all bark and no bite. Both Taiyo and Kyoichiro calls Mutsumi's remarks as blunt as a sledgehammer.
• Clingy Jealous Girl:
  • Subverted. When it looks like Taiyo is cheating on her, Mutsumi insists there must be a reasonable explanation for his weird behavior. Even when she starts coming close to being a Double Subversion, she still decides to hear him out before passing judgment. Good thing too, as he was actually trying to get some of Kyoichiro's favorite (but illegal) tea from a man with an unusually feminine name.
  • It's also subverted when another girl interested in Taiyo, Ayaka, makes herself known. Mutsumi doesn't hold ill will towards her and considers their shared love for him as common ground for them to be friends. This is all likely because Taiyo expressed no attraction towards Ayaka and even doubled down on his marriage to Mutsumi, meaning Mutsumi's jealousy is largely dependent on how much Taiyo reciprocates the other girl's affection.
• Color-Coded for Your Convenience: Deep blue.
• Conditioned to Accept Horror: Growing up with the Yozakuras has almost completely dulled Mutsumi's sense of danger. Handling guns, being kidnapped, and seeing enormous acts of violence and mayhem is business as usual for her. Even when her children are nearly kidnapped by bounty hunters, she's largely able to greet them like usual and apologizes for not being able to act shocked at how scary things were.
• Curtains Match the Window: Deep blue eyes and hair.
• Damsel in Distress: Due to her incredible value as the head of the Yozakura family, Mutsumi is constantly being targeted for assassination and kidnapping.
• Deadpan Snarker: She's so utterly desensitized to the wackiness of her family's profession that her dialogue manages to drip with snark without breaking her Yamato Nadeshiko image.
• Deuteragonist: She is the second-most important character of the story, as the plot's dynamic revolves a round Taiyo's romance and married life with her along with them trying to find stability and normalcy in a family that is anything but.
• Dreadful Musician: Mutsumi's voice is angelic, but she's completely tone deaf and unable to control her pitch, resulting in a sound that knocks out all nearby animals save Goliath and causes flowers to wilt. Taiyo describes it as "the world ending" and all of her siblings save Kyoichiro shudder in fear of her inability to sing, especially since they all have Super-Senses.
• Dude Magnet: Many guys throughout the story want to marry her, only to be furious when they find out that she already has a husband in Taiyo.
• Exactly What I Aimed At: She throws half of Hanawa's gardening shears past his head, which he nonchalantly dodges. However, she really intended to put the shear in Taiyo's reach, allowing him to use it to shatter the other half of the shears and punch Hanawa off the bridge.
• Even the Girls Want Her: She has a number of female admirers who are equally infatuated with her for one reason or another.
• Family Theme Naming: Like the rest of her siblings, she has a number in her name indicating the order in which they were born. Mutsumi is the sixthborn and thus has "mutsu" (six) in her name.
• The Gadfly: She loves to tease her siblings and Taiyo, bringing up their insecurities in jest even while giving them advice.
  Mutsumi: Huh? Aren't you out of bullets now? Are you okay with being empty-handed, Shinzo?
  Shinzo: [sweating and on the verge of Tears of Fear] Don't say it. If I think about it, I can't handle it. I'll really die.
• Give Him a Normal Life: Subverted. Kyoichiro has offered Mutsumi a chance to simply retire from the business and let the Yozakura line end so she can live a normal life on multiple occasions, but Mutsumi refuses every single time because of her feelings of duty to her family.
• Happily Married: Despite the less than ideal circumstances that led to her marriage, Mutsumi is very happy in her relationship with Taiyo. He’s a caring and understanding husband, to the point where she has created merchandise and a love cult based around him, something he’s completely okay with. And they remain happy together during the Time Skip.
• The Heart: As the head of the Yozakura Family and its most valued member, Mutsumi is the glue that binds the Yozakuras together. She knows all of her siblings' quirks inside out and is a source of reason and warmth in the family's most trying times.
• High-Pressure Emotion: When Taiyo manages to make her blush, her first instinct is to run to a fridge and stick her head in it to cool off.
• Hypocritical Humor: Mutsumi often criticizes and feels creeped out by Kyoichiro’s endless obsessive love towards her, even becoming annoyed with his habit of creating merchandise and a love cult about her. However, it’s often shown she’s no different from him, as she also creates merchandise and a love cult about Taiyo, even six years into their marriage. The difference, however, is that Taiyo is completely okay with it and is happy about how much love she has for him.
• Innocent Fanservice Girl: She has no problems inviting Taiyo to bathe with her at a hot spring despite his clear embarrassment over it. She reasons that since they're married, there's no issue with them being in the same bath, and it's not too different from when she bathed with her siblings when they were younger. Taiyo pointedly notes that the situation is quite different, but she covers herself with a towel the entire time.
• Large Ham: When Taiyo has to pretend that they divorced in order to infiltrate a prison, Mutsumi goes all out with the crying and bellows out a Big "WHY?!" as part of the act. When he's finished and leaving the prison, she's still in-character, just a character that Taiyo isn't even sure she's playing.
• The Leader: She's the tenth head of the Yozakuras and ultimately gets the final say in anything they do.
• Lethal Chef: Downplayed. Mutsumi is a good cook, the problem is that the Yozakura recipes for food and medicine tend to be nightmarish to behold. One ancestral manju bun recipe for relieving physical and mental strain caused by Yozakura blood she tries involves adding potassium cyanide, puffer fish, and hydrochloric acid into a blender, and the result comes out looking like something out of the Cthulhu Mythos. In fact, "feeling like you're at the verge of death" after eating it is in the recipe. Tasting it cause Nanao's neck to mutate and turn purple, while Shion's scanners classify it as a deadly weapon. Even Kyoichiro is knocked out for weeks afterward. It turns out the recipe was done in cipher, with the actual steps hidden by invisible ink that can only be seen and performed by those given Yozakura blood, although the final result still knocks Taiyo out when he eats it.
• Living Emotional Crutch: She's the person who kept Taiyo going after he lost his family, and he's always at his happiest around her. As the person who rescued her from being kept in a cage by Kyoichiro, Taiyo is this to Mutsumi in turn, and she's more than happy to die alongside him than live in a world without him.
• Living MacGuffin: As the tenth head of the Yozakura family, Mutsumi is required to produce the next generation of Yozakura superspies. It's later revealed that the Yozakura head produces a unique protein called "someinine" that accounts for the Yozakuras' increased cell division, superhuman strength and dexterity, and Super-Senses. Her blood can even be used as a doping agent by those who aren't Yozakuras, which makes her a hot commodity for Tanpopo, the group that assassinated Taiyo's family and Mutsumi's mother.
• Locked into Strangeness: A streak of Mutsumi's hair turned gray and refuses to be dyed after the incident that drove her brother mad to protect her.
• Luminescent Blush: She's taken by surprise and sports one when Taiyo gives her a (damaged) rose. And later when she kisses him on the cheek.
• Mission Control: When she's not the target of an operation, she provides intel from the safety of the Yozakura estate.
• Ms. Exposition: She's happy to provide explanations about the criminal underworld to Taiyo, who is still getting his feet wet.
• Muggle Born of Mages: She's the member of the family who was born without superpowers and incredible talent for spywork, designating her as the head of the household as well as making her essential for continuing the family line. Chapter 36 reveals this is because of the heads of the Yozakura family produce a protein called someinine in their hearts, which is the source of the members' increased physical and mental abilities.
• Non-Action Guy: Due to being the newest Yozakura head, she doesn't have any of the super talents of her siblings. Because of this, she's usually relegated to the sidelines as Mission Control because of how important she is.
• Only Sane Woman: Once Taiyo starts succumbing to paranoia whenever they're outside together, it's up to Mutsumi to handle him and keep him from drawing too much attention.
• Properly Paranoid: After being assigned to guard her while Kyoichiro is at work, Taiyo notices that Mutsumi never eats anything she's given right away and never goes anywhere by herself out of fear of the assassins constantly after her life.
• Rich in Dollars, Poor in Sense: Having access to the Yozakura bank account means that Mutsumi has a thing for extravagant outfits straight out of period dramas. When Shion asks for help in picking out clothes for a casual date, Mutsumi's selections include 19th century Victorian dresses and a gorgeous kimono fit for a wedding.
• Scars Are Forever: Tanpopo captured her when she was in sixth grade and tried to cut out her heart to make more Hazakura. She has a scar on her chest from that procedure, and she was rescued by her presumed-dead father who gave her to Kyoichiro before turning back to try and rescue Rei.
• Shared Family Quirks:
  • While Mutsumi suffers a lot of grief from Kyoichiro's fanatical devotion to her, she is shown to be just as loyal and violently protective of Taiyo at times. At her order, Goliath will smash through steel walls to attack those who've hurt Taiyo. After the Time Skip, she founds a secret cult venerating her love for him. Kyoichiro even lampshades it, calling them more alike than even he thought.
  • It’s also clear that she has inherited some traits from her grandfather, Ban. While she is far more mature than him, Mutsumi has an insane amount of love for her spouse but is better at hiding it.
• Single-Target Sexuality: As far as many are concerned, Mutsumi has only ever had eyes for Taiyo. Being married to him has led to her loving him even more, to the point where she has created merchandise and a love culture to express her affection. She even enjoys watching a drama show because the lead actor looks a little like Taiyo.
• Teen Pregnancy: Following the five-year Time Skip, Mutsumi becomes a 22-year old mother of two four-year-old twins, implying that she and Taiyo got busy when they were both still 17, which is confirmed when a bounty hunter states the twins are exactly 4 years and six months old.
• This Is Unforgivable!: Mutsumi is cheerfully nonchalant about her own mortality and the countless bounties on her head. But hurting any of her family members, especially Taiyo, sends her into a cold fury that Goliath is more than happy to act on.
• Together in Death: She discusses this with Taiyo when they're both caught in a precarious situation. Taiyo tells her to flee as he's unsure if he can do more than buy time, but she simply embraces him and tells him to calm down, as she'll die along with him if that's the case.
• Tranquil Fury: The most angry she gets is cold and quiet, directed at the people who've managed to hurt Taiyo in her presence.
• Weirdness Magnet: On top of being a constant target for assassins and kidnappers, Mutsumi has some... bizarre people drawn to her, from her oldest brother to Kirisaki to Hatoda.
  Taiyo: You really attract a lot of weirdos...
  Mutsumi: Yes. Sometimes, I feel sorry for myself.
• Yamato Nadeshiko: Aside from her tendencies to be The Gadfly, she embodies this to a T, between her haircut, sense of style, and supportive, loving demeanor while maintaining the ability to remain cool under pressure. She's also incredibly hardworking and works round the clock to support her family.

Kyoichiro Yozakura

Kyoichiro Yozakura

Voiced by: Katsuyuki Konishi (anime, Special Drama), Takahiro Hikami (vomic)

The eldest of the Yozakuras and the family's finest spy, Kyoichiro was hailed as a genius even among his genius family members. But after he made a mistake that nearly killed Mutsumi and left her with a permanent streak of white hair, he became obsessively devoted to protecting her at all costs.

---

• Abhorrent Admirer: His creepy obsession with protecting Mutsumi earns him plenty of scorn from her and others, who often compare him to a dirty old man.
• Absurd Cutting Power: Kyoichiro's Razor Floss can cut through pretty much anything he wants it to, reducing a submarine to pieces in a split second. And when he has no issues turning people into Ludicrous Gibs with it if he deems it necessary.
• Aloof Ally: Kyoichiro is technically on the same side as Taiyo, but also hates him for marrying Mutsumi. Because of this, his "help" tends to be unpleasant at best and deadly at worst, though he'll never actually let Taiyo die because of his family's ironclad rule. This attitude of his softens over time as Taiyo integrates more and more into the family. While he will still prank and annoy Taiyo, he also congratulates him for a job well done and encourages him via Backhanded Compliments.
• Artistic License – Biology: Kyoichiro claims to be able to remain awake constantly by putting half his brain to sleep at any time. Any neurologist would tell you that you need both halves of your brain active for regular functions like motor control and utilizing your senses.
• As Lethal as It Needs to Be: Steel Spider has no problems slicing through steel like tofu, yet Taiyo is able to grip it to force the Cherry Blossom Ring around his finger with only relatively shallow cuts to show for it.
• Amusing Injuries: After Kyoichiro spends a week pranking Futaba by hiding in the walls and ceilings to make it seem as though the Yozakura estate is haunted, Futaba punishes him by twisting his body into a grotesque pretzel for Mutsumi to find. It's played completely for laughs.
• Berserk Button:
  • Taiyo manages to stomp all over this button by being married to Mutsumi. Any sign of escalation in their relationship, such as kissing or bathing together, is also met with ultra-violence.
  • His psychotic overprotectiveness of Mutsumi also means that anyone disrespecting or trying to hurt her better run, lest they face his wrath. Later chapters show that this protectiveness extends to the rest of his family, as he's positively livid when Tanpopo's forces knock out Goliath, forcing Kyoichiro to deactivate the wire trap to protect him. He then promises the man who punched Goliath a slow, painful death.
• Big Brother Instinct: For all his flaws, the Kyoichiro's most consistent virtue is his deep, abiding love for his family and his fervent desire to protect it. While he displays this to an unhealthy extent regarding Mutsumi, harming any of his siblings is one of his two Berserk Buttons. As the eldest, he considers himself the Yozakuras' first line of defense and will put himself in the firing line before any of his siblings get hurt. He even tricks them all into thinking he's run off to sulk when he's actually leaving to fight Tsubomi and the revived Yozakura heads alone. He's also instantly protective of Alpha and Hifumi, his nephew and niece, following the Time Skip, threatening to kill anyone who dares to lay a finger on them.
  Kyoichiro: I stand between you and my siblings. Since the beginning, I had no path of retreat!
• Broken Ace: Kyoichiro is an Implacable Man said to be the family's finest spy, easily overwhelming his siblings despite their best efforts to impede him. But his lingering guilt over how a mistake of his badly injured Mutsumi has made him a Knight Templar Big Brother who brutally beats or even murders anyone he perceives as a threat to her. It's gotten to the point he's alienated his other family, Mutsumi included.
• Bunny-Ears Lawyer: Kyoichiro is one of the best spies in the world, but he's also a Knight Templar Big Brother.
• Character Development: It's noted in Chapter 49 that he's remarkably less violent towards Taiyo, even if he still hates him and wants to leave him for dead.
• Character Tics: He chews on his own Razor Floss whenever he sees or hears about Taiyo getting close to Mutsumi.
• Charles Atlas Superpower: He can throw pieces of chalk faster than the speed of sound and move with inhuman precision, threading one of his wires through a bomb the size of a piece of candy to stop its triggering mechanism without setting it off. He's also trained himself to not require sleep, and claims that he has never completely fallen asleep since he was 15.
• Color-Coded for Your Convenience: His color is black.
• Cool Big Bro:
  • Before his obsession with Mutsumi became all-encompassing, Kyoichiro was considered this as the most reliable member of the family. Part of the reason why Futaba wanted Taiyo to marry Mutsumi was the hope that Kyoichiro would return to his old self again once he realizes that Mutsumi is in good hands. Even still, Kyoichiro stops to give his little brother Shinzo words of encouragement after Taiyo is critically injured before Shinzo's eyes. He's also thoroughly supportive of all of his siblings' ambitions, insisting Nanao head to college rather than throw himself into the family business.
  • When Nanao's medicine reverts Kyoichiro to when he was six-years-old, Kyoichiro confesses to Taiyo that his obsession with Mutsumi began as his Big Brother Instinct. As the eldest, he feels it's his job to protect his family and his home from any that would hurt it. Mutsumi's sheer importance to the Yozakuras along with his own premonitions of looming disaster for the family amplified those feelings into a fixation on keeping her safe.
  • When Ai is taken in by the Yozakuras, Kyoichiro vanishes for the entirety of the chapter until the last panel, where it's revealed that his Big Brother Instinct was so intense that he bought her a small mountain of gifts but knocked himself unconscious trying to decide which one to present to her.
• Cool Uncle: He gently offers Alpha and Hifumi advice on how to improve their skills while threatening anyone who dares to harm the twins with death. This a threat he makes good on in Paris, as he massacres bounty hunters who come after the twins. He's also responsible for designing Alpha's and Hifumi's signature weapons.
• Creepy Uncle: Alpha is disturbed by the obsessive affection Kyoichiro gives him and Hifumi due to them being Mutsumi's children. Hifumi is too at first, but she quickly sympathises with Kyoichiro due to her own obsessive affection for Alpha, much to Alpha's dismay. Then his attempted murder by shark of Taiyo and Alpha’s tearful reaction to it resulted in her opinion of souring anew and she once more thinks of him as creepy.
• Declaration of Protection:
  • He gives a horrifying parody of one to Mutsumi as part of his obsession with protecting her in the first chapter.
    Kyoichiro: It's because you go outside that these pests swarm around you. I've protect you much, much better from now on...
    Mutsumi: [thoroughly creeped out and backing away] Brother?!
    Kyoichiro: It's dangerous, so you shouldn't go outside. The internet is dangerous too, so you won't need your smartphone. Let's just get rid of anything that has the potential to be dangerous to you. School... friends... having fun... romance... let's get rid of it all. We'll get rid of everything unnecessary so you can have a safe and peaceful home life with your family. Ahh, just thinking about it makes my heart giddy. [grabs her wrist to get her to stab him without flinching] That day I almost lost you,... I made a vow to protect you... even if others were hurt. [pulls her close against his chest] I would give up my life... to protect you, dearest. Now, Mutsumi... forget all about him and let us live in peace.
  • Kyoichiro makes a more traditional declaration upon meeting his niece and nephew, declaring that he will kill anyone who dares to lay a finger on Hifumi or Alpha. In Paris, he makes good on this threat by reducing a group of bounty hunters who came after the twins into giblets in a single motion.
• Dissonant Serenity: In Chapter 180, Kyoichiro is in a fantastic mood after Alpha and Hifumi start to reciprocate his affection for them and happily carries them back to the hotel they're staying at. So when bounty hunters come after the twins, Kyoichiro says he'll do his foes the honor of treating them as true "enemies". So he turns the bounty hunters into Ludicrous Gibs with disturbing ease. When Alpha asks what happened, Kyoichiro gently tells his nephew to go back to sleep.
• The Dreaded: Kyoichiro is feared as the most dangerous of the Yozakuras both for his skills and his psychotic obsession with Mutsumi. The Hinagiku even have an emergency code explicitly for him: Code Cherry Blossom Blizzard, for when he invades their headquarters after Mutsumi stops by for a visit.
• Dynamic Entry: He smashes through the wall of Hinagiku's bunker after he realizes that Mutsumi's signal disappeared off his GPS.
• Establishing Character Moment: He's shown beloved by the students in class while creepily eating the lunch Mutsumi left for Taiyo against her wishes, showing just how obsessed he is with her. Later that day, he's shown allowing Mutsumi to stab him while declaring how much he wants to protect her.
• Evil Cannot Comprehend Good: After all the shit he put Taiyo through, Kyoichiro cannot fathom the idea that Taiyo would ever do anything nice for him. So when he undergoes a variety of covert missions just to get Kyoichiro his favorite brand of illegal tea, Kyoichiro opts to choke himself unconscious rather than accept it.
• Eyes Always Closed: Even while giving people Death Glares, his eyes are never opened.
• Family Theme Naming: Like the rest of his siblings, he has a number in his name indicating the order in which they were born. Kyoichiro is the firstborn and thus has "ichi" (one) in his name.
• Foil: To Taiyo. Both are impacted by incidents that involved another family member (Taiyo lost his entire family while Mutsumi was heavily injured). However, while Taiyo ends up pushing away those willing to reach out to him out of fear of losing them, Kyoichiro becomes a Knight Templar Big Brother that obsesses over Mutsumi's safety to where he alienates his entire family and ignores Mutsumi's wishes.
• The Friend Nobody Likes: While all of his siblings love him and Taiyo at least respects him as his brother-in-law, it's clear that Kyoichiro's obsessive and annoying behavior makes him the least-liked member of the family. Missions where he has to be away for prolonged periods of time or when he runs off to sulk are treated like spa days by the other Yozakuras. Taiyo is normally so high-strung around him that his body goes weak as he can finally relax a little without Kyoichiro to stress him out. Lampshaded by Taiyo, who notes how mean it is for the rest of the family to treat Kyoichiro like this.
• Future Me Scares Me: A physically and mentally-reverted Kyoichiro is aware of his growing obsession with Mutsumi and the thoughts he's been having scare him. He knows he'll become a horribly unpleasant person in the future because of them and is ashamed of himself after seeing his (from his perspective) siblings' future reactions to him.
• Groin Attack: He forces Taiyo to perform one of these on an unsuspecting mook while using him as a People Puppet.
• Helicopter Parents: Well, uncle. Kyoichiro's obsessive desire to protect and dote on Alpha and Hifumi fails to endear him to them, as he comes across as creepy rather than affectionate. It's only after Mutsumi tells Kyoichiro to give them some space and let them do things on their own do the twins finally start to open up to them.
• Heroic Comedic Sociopath: When Kyoichiro isn't the antagonist, his obsession with Mutsumi is Played for Laughs. His attempts to "train" Taiyo in painful and potentially murderous ways are played for slapstick, he casually floats on his back as a torpedo comes towards him without a hint of concern for the crooks around him, and Mutsumi manipulates him by giving him praise and false promises.
• Hyper-Awareness: Kyoichiro is incredibly precise and attentive to detail, able to thread a single wire of Steel Spider through a bomb at the precise angle to avoid setting it off. Even when reverted to his childhood days, he's able to deduce that he took the wrong medicine and was in the "future" solely by noticing the differences in his room and the discrepancy between the date he knows and the family photo album. This same attention to detail gave him a premonition of horrible things the Yozakuras are going to experience in the future, resulting in his Big Brother Instinct for his siblings turning into his Knight Templar Big Brother fixation on Mutsumi.
• Hypocrite: Kyoichiro chastises his grandfather Ban as a "failure of a professional" for his Loose Lips when it comes to classified intel. This is coming from the guy who posts all of the Yozakuras' activities on social media.
• Implacable Man:
  • Even with his five siblings ganging up on him all at once, the worst Kyoichiro gets is a few scuffs on his suit as he easily repels all of them. According to Shion, all five of them have only won thirty percent of their fights with Kyoichiro, and there's an 85 percent chance that someone will need six months of recovery time and a 25 percent chance the house will burn down.
  • He says with complete and utter certainty that a direct hit from a torpedo will have no absolutely no effect on him, even if the people next to him will get blown to smithereens.
• Ineffectual Death Threats: Despite threatening to kill Taiyo on multiple occasions, Kyoichiro never follows through because that would make Mutsumi sad, as Mutsumi bluntly points out:
  Mutsumi: He loves me so much he can't make himself be nice to papa, so he picks on papa to try to maintain his self-image. In reality, it's all one big dumb act.
  Kyoichiro: N-No it's not..!
  Mutsumi: Think about it. He could never do anything to make me sad. Occasionally hazing papa is the best he can manage. It's like dogs that are all bark and no bite, or a thug's posturing.
• Irony: His Knight Templar Big Brother tendencies lead to him trying to kill Taiyo, and the latter's resulting marriage to Mutsumi. His pettiness over the matter and trying to exploit Loophole Abuse to get rid of Taiyo end up putting Mutsumi in MORE potential danger.
• Jerkass to One: Kyoichiro makes it his life's mission to make Taiyo miserable, threatening him with torture and death at every turn. Aside from this, he genuinely loves his siblings and gradually gets to show his old Cool Big Bro side of him as the story goes on.
• Knight Templar Big Brother:
  • A long time ago, Kyoichiro made a mistake that badly injured Mutsumi, stressing her so badly that she gained the streak of gray in her hair. Because of this, he's resolved to protect her no matter what, beating up or murdering anyone he sees as a possible threat to her. He even says he'll simply lock her in the house where she'll be under surveillance 24/7 to ensure that she's perfectly safe. Even after Taiyo marries Mutsumi, Kyoichiro continues to seethe with animosity for him and wonders if he can Make It Look Like an Accident.
  • His obsession with Mutsumi is so extreme that he goes into withdrawal and gets tremors when he's separated from her for too long. Some of the low ranking reviews for the Yozakura family are revealed to be from individuals who find his obsession with Mutsumi creepy and unsettling. At one point, a member of the Hinagiku bluntly states Kyoichiro confines Mutsumi (before doing a Verbal Backspace to protecting her) when explaining why Taiyo had to keep his mission to secure Kyoichiro's favorite tea a secret from Mutsumi.
  • Even before the incident, Kyoichiro was overly affectionate with her as a child and starts a fight with all of his other siblings when she was pried from his grasp by his mother and Futaba.
• Major Injury Underreaction: He doesn't even flinch when he has Mutsumi stab him while he doles out a horrifying Declaration of Protection, showing just how insane he is in protecting her.
• Muscles Are Meaningless: He's shorter and leaner than his younger brother Nanao, but the youngest Yozakura struggles to hold an irate Kyoichiro back from attacking Taiyo at his and Mutsumi's wedding reception.
• My Greatest Failure: Kyoichiro is haunted by the time Mutsumi was kidnapped and nearly killed, regarding it as his single greatest failure. While he was merely clingy and overprotective before, Kyoichiro's sanity nosedived after this, turning him into the Knight Templar Big Brother by the current events of the story.
• My Sister Is Off-Limits: Even though Taiyo and Mutsumi are married, Kyoichiro maintains this stance, forbidding Taiyo and Mutsumi from kissing or bathing together at an inn. When the former happens, Kyoichiro cries tears of blood and is ready to rend Taiyo limb from limb. When the latter happens, he abides by the inn's Thou Shalt Not Kill rule and instead starts a massive pillow fight to try and get Mutsumi back. Even five years later, he threatens to feed Taiyo to a shark for daring to bed Mutsumi.
• No-Sell: His desire to protect his family is so strong that he is completely immune to his father's Lotus-Eater Machine Blooming, as he never stopped loving Momo, but is equally determined to kill Momo for the sake of protecting the other Yozakuras.
• Obnoxious In-Laws: Of all the Yozakuras, Kyoichiro stands out as the only one who's intentionally obnoxious to Taiyo, taking every excuse to try and rough him up as consolation for not being able to kill him. He even puts a bounty on Taiyo's head at Taiyo's own wedding reception and buys rare and expensive books to learn about new ways to torture him. Even when Taiyo is on the brink of death from being shot repeatedly, Kyoichiro still finds it in him to draw on Taiyo's face with a marker, earning him a stern punch from Futaba and getting dragged away by Nanao.
• Oh, Crap!: Kyoichiro panics when Futaba catches him pranking her and preying on her fear of ghosts. She then proceeds to twist him into a pretzel for his antics.
• Out-of-Character Alert: Taiyo is immediately on edge when Kyoichiro kidnaps him for a "friendly fishing trip" and treats him unusually nicely. It doesn't take long for Taiyo's suspicions to be proven right, as he's immediately besieged by assassins out for the bounty Kyoichiro put on his head.
• People Puppets: He does this to Taiyo with super-thin versions of Steel Spider's threads in order to engrave the motions of being a spy into him via muscle memory.
• Perpetual Smiler: Serves to emphasize his craftiness and barely concealed rage along with his constantly closed eyes.
• Pet the Dog:
  • Despite his frequently vocalized animosity for Taiyo, Kyoichiro offers some words of encouragement after Taiyo is humiliated by Sui, telling him that the Yozakura name wouldn't be sullied so easily. His "lessons", while rough, are also surprisingly fair and designed with the mindset that Taiyo is more than capable of handling them. Kyoichiro also assures Taiyo that no matter how much he might want him dead, he's still family.
    Kyoichiro: In this world you may even doubt yourself. But there's one thing you can trust, and that is family. I may want to kill you, but I'll never let you die, even if it kills me.
  • When Taiyo briefly goes berserk from Sensory Overload, Kyoichiro has Mutsumi subdue him with her singing rather than the typical method of simply knocking him to his senses. Futaba lampshades this and says he's being too nice. Kyoichiro merely smirks and calls it a whim.
• Psychopathic Manchild:
  • At his worst, Kyoichiro can be astonishingly petty and childish, finding the flimsiest reasons to beat the crap out of Taiyo and showing unhealthy possessiveness of Mutsumi even towards his other siblings. He exploits Futaba's fear of ghosts to prank her and is so taken aback by the thought of Taiyo being nice to him that he strangles himself unconscious with Steel Spider rather than accept the fact.
  • This behavior of his is so rampant that the Yozakuras are floored when he's physically and mentally reverted to his childhood, where he's nothing but friendly, polite, and cheerful. He was far more mature and better-adjusted at age six than he is at 21.
• Razor Floss: Kyoichiro's preferred weapon is Steel Spider, a set of gloves that produce seemingly endless amounts of wire that can rip apart an entire mansion. He demonstrates incredible precision with them and can seemingly utilize them as an extension of his own body, threading one of his wires through a bomb the size of a keychain to stop its triggering mechanism. He also has different wires of varying sharpness and hardness, allowing him to harmlessly restrain others and defend himself from attacks by weaving complex webs of wire.
• Tears of Blood: Cries these when he witnesses Mutsumi give Taiyo a peck on the cheek. If not for the Hinagiku, Kyoichiro would have almost certainly murdered Taiyo then and there, Yozakura rule be damned.
• The Sleepless: He has trained himself to be able to sleep with half of his brain at any given time. He claims to have "graduated" from the need for complete sleep when he was 15. Taiyo lampshades the absurdity of this.
  Kyoichiro: [tapping through Morse code] I graduated from complete sleep when I was 15 and have been awake ever since.
  Taiyo: [tapping back] That's like graduating from being human!
• Sadist Teacher: He takes gleeful pleasure in harassing Taiyo whenever possible in class, using the pretense of training to have an excuse to try to injure him with pieces of chalk thrown at the speed of sound. He also ties a 100 kg weight to Taiyo and tries to throw him into the sea for "underwater training" until Taiyo is snatched away by Kengo.
• Sanity Slippage: When Kyoichiro was a child, he was the perfect older brother: cheerful, doting, and responsible. But as the eldest son, he felt it was his responsibility to defend the Yozakura family and estate above all. After Mutsumi was born, the sheer value she held to the family caused him to become clingy and possessive of her due to his overactive Big Brother Instinct. After the incident that nearly killed her, Kyoichiro's sanity nosedived, his protective instincts and desire to atone for his failure to protect her warping him into the Knight Templar Big Brother Taiyo meets in the present.
• Stern Teacher: He's this to Taiyo after Mutsumi is kidnapped, forcing him to learn the motions of being a spy by using him as a People Puppet and constantly revitalizing him with Nanao's drugs without caring if Taiyo's heart explodes in the process. Despite this, most of his instructions are surprisingly fair, if strict, and he doesn't chastise Taiyo for giving up a chance to find Mutsumi by saving a little girl bound for human trafficking.
• Swords Set To Stun: Steel Spider apparently has numerous kinds of wires for both heavy-duty and delicate purposes. One set of wires can cut through steel like tofu, while others can harmlessly hold someone in place.
• Tears of Blood: Cries these when he catches Mutsumi giving Taiyo a peck on the cheek.
• Took a Level in Kindness: Kyoichiro's opinions of Taiyo soften and improve as the story goes on. He goes from threatening Taiyo with torture and putting bounties on his head every other chapter to offhandedly encouraging him and even congratulating him on a job well done. Kyoichiro also becomes less clingy to Mutsumi, giving her freedom so long as Taiyo is around to protect her, a far cry from his original plan to keep her locked in a Gilded Cage. Invoked by Futaba, who specifically brought Taiyo into the family to help Kyoichiro let go of his paranoia and go back to being a Cool Big Bro.
• Tranquil Fury: Kyoichiro's rage boils over into icy fury when Tanpopo forces him to deactivate Cocoon Husk to prevent Goliath from being cut to bits and mocks the Yozakuras' love for one another. Rather than immediately fly into a rampage, Kyoichiro remains completely and utterly calm on the surface while promising his assailant a slow, painful death and swearing to retrieve the ring of the previous Yozakura head. Notably, this is the first time Kyoichiro's anger has been shown without it being directed at Taiyo or being played for slapstick comedy.
• Used to Be a Sweet Kid: When a mishap involving Nanao's medicine physically and mentally reverts Kyoichiro to when he was six-years-old, everyone is floored by how honest and sweet Kyoichiro is. He happily congratulates Mutsumi on her marriage, gushes praise and affection on all his siblings, and is generally an adorable Cheerful Child. He confesses to Taiyo that his obsession with Mutsumi began because of how important she is to the family. As the eldest, he felt it was his duty to protect her and his family's home no matter what. More than anything else, he's scared and ashamed of the unpleasant person he becomes in the future.
• Walking Wasteland: His Blooming, "Void", imbues Steel Spider with his blood to devour everything in his vicinity, slicing it all into bits too fine for the eye to see before completely dissolving them. Only his strongest defensive technique, the Goddess Web, Arakune, is capable of shielding others from his Blooming, which eats away at a battleship he's standing on and reduces it to fine particles.
• What Does She See in Him?: Kyoichiro is constantly asking this question after Taiyo and Mutsumi agree to marry.
  Kyoichiro: [chewing on his own Razor Wire] Such an admirable girl... S-She's such a sweet girl... So why... is she with this guy.
• The Worf Barrage: Kyoichiro pulls out a new technique "Calm Storm" that gouges the landscapes upon use, but it's completely nullified by his own father to demonstrate how skilled the latter is.

Futaba Yozakura

Futaba Yozakura

Voiced by: Akari Kitou (anime), Miki Maruyama (vomic), Yukari Tamura (Special Drama)

The responsible second child and Mutsumi's eldest sister. Her diminutive stature belies her incredible strength and skill in hand-to-hand combat.

---

• Attack Reflector: The fundamental principle of Futaba's aikido-focused martial arts is to turn her enemy's strength against them. By returning the force of their attacks, she can amplify her already crushing blows while minimizing if not nullifying any damage she would have taken in return. She can also manipulate the wind by harnessing the flow of the air as well as split the sea by manipulating water currents.
• Bare-Fisted Monk: Her specialty is martial arts, be it with ribbons or her bare hands. She's so good at it that even Kyoichiro would not dare face her in a one-on-one duel.
• Berserk Button: Like her younger sister Shion, Futaba hates cheaters. Whenever Futaba sets a challenge in front of her family members, it's to help them grow and improve. So cheating at those challenges quickly sends Futaba into a rage. Kyoichiro pushes this button on purpose to put himself and Hifumi is a situation dangerous enough to activate Hifumi's Blooming, though even he underestimated just how angry Futaba would be.
• Big Little Brother: Despite being the second-eldest of the Yozakuras, she's shorter than all of them. This is especially noticeable when she's standing next to Nanao, the youngest of the family. In one scene, she accompanies Mutsumi to school and the high school girls mistake Futaba for Mutsumi's little sister.
• Blow You Away: Her mastery of martial arts lets her generate whirlwinds with her hands that she can use to disperse harmful attacks like fire and poisonous gas as well as stop entire trains. After the Time Skip, her mastery of aiki has grown to the point that she can generate tornadoes that can drill through bedrock just by waving her hands.
• Brainwashed and Crazy: She and Shinzo are brainwashed by Momo's parasitic creatures into becoming loyal to him and agreeing with his plan to make them one happy family again, regardless of the cost to others.
• Can't Hold His Liquor: She laughs hysterically after getting splashed with sake and quickly starts attacking all of the gang members who happen to be attending the same inn as her.
• Color-Coded for Your Convenience: White, in contrast with her older brother's black.
• Cool Aunt: She introduces herself to her niece and nephew by offering to help train them before showering them with comforting hugs, delicious tea and sweets, and cleaning their room for them. Both Alpha and Hifumi quickly grow attached to Futaba as a result, to the point of fighting over who gets to hug Futaba in their sleep.
• Cool Big Sis: She's the voice of reason in the family and knows when to be stern and when to be soft. As a result, she has a good relationship with everyone in the family and reins in Kyoichiro's worst habits. Futaba is also touched by Taiyo's love for Mutsumi and is the first to offer him the chance to train to keep up with the rest of the Yozakuras. She has such intense "doting older sister" energy that her nephew, Alpha, instinctively calls her "Big Sis" despite her being his aunt. On the other hand, this makes Hifumi, Alpha's actual older sister, jealous that Futaba is so much better at making him happy than she is. Once Futaba realizes this, she apologizes for accidentally taking Hifumi's role as older sister.
• Cute Bruiser: She dresses in all gothic lolita clothing, but she's still able to toss Taiyo around like a ragdoll. It's later revealed that while Kyoichiro has defeated all of his siblings at once before, he's never won a one-on-one duel with Futaba in hand-to-hand combat. His attempts to prank her through the walls end with him getting twisted into a pretzel for Mutsumi to find the following morning.
• Dance Battler: When she isn't using her bare hands, she can perform Instant Knots with her ballet ribbons and toss people around with them. The art generally portrays her as incredibly graceful with them, beating her way through huge crowds with frightening speed.
• Family Theme Naming: Like the rest of her siblings, she has a number in her name indicating the order in which they were born. Futaba is the secondborn and thus has "futa" as in "futatsu" (two) in her name.
• Fragile Speedster: As strong as she is, her tiny frame means that anyone strong enough to parry her blows can force her back easily because of her lack of body weight. She bemoans this while trying to apprehend Hanawa the Courier.
• Hopeless with Tech: She's bad with anything electronic to where a keyboard is too complex for her to use, so Shion has to manage her electronics for her.
• Lightning Bruiser: She's incredibly strong, fast, and precise, able to take on everything from bullets to fireballs with nothing but her bare hands.
• Muscles Are Meaningless: She's a tiny little thing, but she can casually throw people around and cause severe structural damage with ease.
• Older Than They Look: Her diminutive height and cutesy gothic lolita dress makes it easy to assume she's Mutsumi's younger sister rather than her eldest. When she meets her nephew and niece for the first time, Hifumi mistakes her for someone close to their age and accuses Alpha of bringing a woman into their room.
• No-Sell: Her fighting style specializes in redirecting force to brush off her enemies attacks. Her Blooming, Magnanimity, boosts her kinetic vision to the limit, which combined with her martial art skills, allows her to instantly nullify incoming attacks. Even enormous fireballs large enough to reach miles into the sky can be completely smothered with her bare hands.
• Pre-Asskicking One-Liner:
  • Delivers one when she and the others go off to face more than a thousand Hazakura-enhanced soldiers invading their estate.
    Futaba: We have an injured person at home right now... so I'll have you take your leave.
  • She has another one when she uses her Blooming against Akai, an agent of Tanpopo using her own version of Blooming.
    Futaba: Out of respect for another eldest sister... I will accept all of your hostility and murderous rage.
• The Reliable One: Futaba is as competent and wise as Kyoichiro but lacks many of her siblings' quirks and neuroses. As a result, she's a source of reason in the family and one of the go-to people for others to confide in.
• Super-Strength: Futaba is deceptively strong, leaving a giant crater in the floor when she slams Kyoichiro into the ground. She once destroyed an entire haunted house after being startled by the "ghosts" there. She was even able to stop a train with her bare hands.
• Weaksauce Weakness: For all her strength and skill, there is one hold that she can't break out of, no matter how much she tries: A specific hug done by her mom. Shion is able to pull it off, by using her Blooming to analyze all of her memories of their mom to do it exactly like she did.
• Women Are Wiser: She's the most reasonable of the Yozakuras by far, especially when compared to Kyoichiro. When he isn't around, she takes up the de facto leadership position.
• Why Did It Have to Be Snakes?: For all her strength, she's terrified of ghosts because they can't be fought with martial arts. Mutsumi recalls a time when she took Futaba into a haunted house, which spooked Futaba so badly that she destroyed the place. Except,this is just an act she puts on. She confesses to Taiyo she's actually terrified of losing the people closest to her and seeing depictions of ghosts reminds her of the people she failed to protect, such as her mother, despite her best efforts. Futaba allows her siblings to believe she has a fear of ghosts to prevent them from seeing her lack of confidence in her ability to protect them.

Shinzo Yozakura

Shinzo Yozakura

Voiced by: Kazuyuki Okitsu (anime), Makoto Araki (vomic), Jun Fukushima (Special Drama)

The constantly jittery third child of the family, specialized in all kinds of weapons, from swords to firearms. He often hides in a trash can.

---

• Ace Custom: Version Zero Super-Size Yozakura Electric Gun "Spring Thunder" is his personal version of "Yae", the Lightning Gun he gives to Taiyo. It's unwieldy and extremely complex, to the point that Shinzo is the only one who can handle it. But its sheer power can be compared to being struck with an actual lightning bolt.
• Afraid of Their Own Strength:
  • Shinzo hates his Blooming because of its tendency to send him into a berserk rage destroying everything in his path. But his mother told him that it's alright to be afraid of his own power, as the only ones who are fearful of their own abilities are the ones who are both strong and kind.
  • When Taiyo is essentially reverted to a baby by one of Nanao's medicines, Shinzo plasters himself onto the ceiling and refuses to touch Taiyo, as he fears that Taiyo would explode if he so much as laid a finger on him.
• Anger Born of Worry: Shinzo is not pleased when Kengo and Nanao rope Taiyo into tailing Shinzo's shopping trip in an extremely dangerous mall he explicitly told them not to enter. So he takes Ayaka's suggestion to confidently express his love as a reason for doling out "loving punishment" to discipline his younger siblings. By the end of it, all three of the younger Yozakuras are clinging to Futaba for protection around Shinzo, who wonders if he overdid it.
• Badass Boast: Dishes one out when he finally pulls out his Blooming against Kurosawa, a Living Weapon.
  Shinzo: My Blooming, "Destroy", can crush any weapon, including you!
• Beware the Nice Ones: Although he's an Extreme Doormat and a gentle person at heart, he's a force to be reckoned with when armed. When pitted against Kurosawa, a serial killer who has never felt fear, Shinzo's relentless attacks and raw determination to defeat him strike terror into the Tanpopo agent's heart.
• Big Damn Heroes: When Taiyo is cornered by the Tanpopo agent Nohmen, Shinzo busts through the door guns blazing to rescue his little brother.
• Bizarre and Improbable Ballistics: Shinzo's Improbable Aiming Skills are so extreme that he has special bullets he ricochets of walls and ceilings straight into people's blind spots when he's standing in front of all them. Even while holding back for an exam, he can shoot a hundred people and knock them all out cold in an instant. The art shows that these bullets moved at right angles, in zig-zags, and even in triangular patterns before hitting their targets.
• Brainwashed and Crazy: He and Futaba are brainwashed by Momo's parasitic creatures into becoming loyal to him and agreeing with his plan to make them one happy family again, regardless of the cost to others.
• Cerebro Electro: Shinzo is the Yozakura Family's weapons and firearms expert. In addition to his impeccable aim and fine motor skills, Shinzo is a skilled engineer and weaponsmith who developed Yae, Taiyo's Lightning Gun, as well as his own Ace Custom version that is so technically complex that no one but Shinzo is capable of wielding it. This gun is so powerful that a shot from it feels like an actual lightning bolt.
• Color-Coded for Your Convenience: Distinguished from the rest of the cast by his deep green hair.
• Combat Pragmatist: He shoots the hands and guns of his pursuers rather than outright killing them so their comrades will stop to tend to them rather than continue chasing in search of vengeance.
• Cool Big Bro: He wants to be this for Taiyo after he's married into the family, promising to become more reliable and less jittery and insisting that he's Taiyo's older brother. He also easily caves when Nanao uses Puppy-Dog Eyes on him and tries his best to hide the porn Kengo and Shion are watching from Nanao's eyes. He's also the first to ask if Taiyo is okay after fighting Kawashita in the depths of his laboratory and being injected with a deadly poison.
• Cover Innocent Eyes and Ears: This is Shinzo's instinctual reaction to Nanao after Shion and Kengo start nonchalantly watching porn in the middle of thier hotel room.
• Cowardly Lion: Despite being a world-class spy who has been in and out of war zones, Shinzo is a complete and utter wimp when unarmed. The mere thought of going into a fight without a gun in his hand makes him curl up in a corner and cry, and his pacifier was shaped like a magnum bullet casing. But hand him any kind of weapon and his demeanor takes a 180, making him focused, confident, and analytical.
• The Dreaded: Zigzagged. Outside of a combat zone, Shinzo's shyness and frayed nerves make him one of the most hapless of the Yozakuras. He's easily pushed around by his siblings and is generally too nice for his own good. But when it comes time to fight, his firepower and accuracy are off the charts. So when Taiyo is pitted against him for an exam, the first thing Shion and Nanao advise Taiyo to do is to run for his life.
• Endearingly Dorky: He tries his best to look cool despite his timidity and tends to freak out whenever he's embarrassed. Mutsumi is quick to tease him for it and Shion scoffs at his indecisiveness, but his niceness also endears him to the rest of the family.
• The Engineer: Shinzo's skill with weapons also extends to overall familiarity with engineering and technology. He's responsible for many of the Yozakura's gadgets, traps, and weapons, though the other Yozakuras also make their own tech, such as Kengo's dolls and disguises.
• Extreme Doormat: Downplayed. Shinzo is easily the most passive of the Yozakuras overall, and can only feebly beg Shion to stop taking his meat while she dumps her vegetables on his plate. He could easily stop her with brute force, but the thought never seems to occur to him. That said, this passivity seems to only apply when in the house, as Shinzo is determined and confident in the field when he has a weapon in hand.
• Face of a Thug: Downplayed. Shinzo isn't bad looking at all, but the way he pants while out in an open area (often while handling a weapon) gets outsiders to think he's a Blood Knight fantasizing about killing people. In truth, he's panicking due to his shyness, even moreso when accompanied by Ayaka in a date-like fashion.
• Family Theme Naming: Like the rest of his siblings, he has a number in his name indicating the order in which they were born. Shinzo is the thirdborn and thus has "zo" (three) in his name.
• Gun Nut: On the rare occasion he is able to relax, he can spew a Wall of Text on any given firearm or weapon at will. Taiyo has to zap Shinzo with Yae to get him to stop talking so much.
• Heavy Equipment Character: Shinzo's combination of Super-Strength and Improbable Aiming Skills makes him the weapons specialist of the family. His personal Ace Custom weapons are too heavy and complex for anyone else to use, but they pack severe firepower even when he's going out of his way to avoid killing.
• I Call It "Vera": The lightning pistol he gifts Taiyo is called "Yae", while his personal Ace Custom version is "Version Zero Super-Size Yozakura Electric Gun 'Spring Thunder'".
• Improbable Aiming Skills:
  • His specialty, given his mastery of any and all kinds of firearms. For instance, he detonates a grenade early by shooting it seconds after he's already thrown it. He can even throw forks with enough force and precision to shatter a sniper's scope. He sends a bullet up the barrel of said sniper's gun immediately afterward to make it fall to pieces.
  • While acting as the proctor for the first phase of the Silver Rank Spy Exam, he ricochets a hundred bullets straight into a hundred different people at different angles to strike their blind spots. All while using specially-made bullets designed to only knock someone out cold.
• Lightning Gun: Taiyo's signature lightning pistol "Yae" is one of Shinzo's inventions, able to shock people with up to 2 million volts of electricity. Shinzo also has a hulked out version of it more akin to a lightning bazooka that's so complex and hard to handle that he's the only one who can use it.
• Like Brother and Sister: Shinzo and Katana are purely just Childhood Friends despite Alexandryu's efforts to be a Shipper on Deck for them. Katana explains that she doesn't feel attracted to macho guys because they remind her too much of her ridiculously buff adoptive father. On the same note, she's heard so much Gun Nut talk from her biological father that she's honestly tired of it. So while they enjoy each other's company, Shinzo and Katana have no intention of getting together much to Alexandryu's surprise when he tries to force them into an arranged marriage.
• Master Swordsman: His weapon specialty means that he's equally capable with a sword, casually performing complex movements that Taiyo struggles to keep up with and absentmindedly thrusting him into a wall with a simple shinai. After he modifies Yae to turn into a sword, he teaches some of these skills to Taiyo.
• Morph Weapon: Ukon-Tumeric-Cherry Blossom is a weapon made of a fluid alloy that Shinzo can manipulate at will. It's noted to be incredibly difficult to control, as its properties are derived from dozens of other alloys. But with it he's able to create virtually any kind of weapon he desires, such as a hammer that can smash through steel, a pair of giant scissors, or a cleaver with Absurd Cutting Power that cleanly slices through the nuclei of individual cells to kill it and halt regeneration.
• Mr. Fanservice: He's muscled all over and his tendency to go out with nothing more than cargo pants and a vest on flaunts his body to everyone despite his shy personality. In one chapter he winds up winning a professional bodybuilder's competition because of how ripped he is.
• Mundane Utility: As long as Shinzo thinks of it as a weapon, he can use it proficiently as one. This proves handy when all he has is a fork to disarm a sniper, but when it comes to ping pong, he gets so into it that he takes on three of his brothers at once and leaves the wall behind them riddled with cracks.
• Powerful, but Inaccurate: His Ace Custom version of the Lightning Gun he gives Taiyo, the "Version Zero Super-Size Yozakura Electric Gun "Spring Thunder", is many times more powerful, but is complex to use and has such recoil that only he can handle it. His opponent mocks him for using such a telegraphed and easily dodged weapon due to its conspicuousness and charge time... but Taiyo is there to destabilize the floor with a bomb, leaving the target wide open to a direct hit.
• Security Blanket:
  • He's a complete Nervous Wreck when he's unarmed and needs to have some kind of weapon on him to feel safe. This is why he's usually hiding inside his trash can, which is armed to the brim with assorted weaponry ranging from guns to missiles to drills. That said, this weapon can be almost anything he can hit someone with, be it a gun or a fork.
  • Futaba ends up sewing him a pair of iron-knitted gloves for him to wear so he's never truly unarmed. Even after the mission, he still complains about things being scary.
• Sherlock Scan: His Blooming, "Destroy", cranks up his senses to the point that he's able to understand how any weapon works nigh-instantly, as well as how to break it. With it, he's able to analyze the perfect angle of attack, vibration frequency, and amount of force needed to destroy anything.
• Super-Strength: While not as pronounced as Nanao's, Shinzo possesses extreme physical strength even when compared to the other members of the family. It's part of the reason why he's able to use all kinds of weapons, as his strength ensures that they'll never be too unwieldy for him to carry no matter how much he brings with him.
• Super-Toughness: When Nohmen takes an entire hotel hostage with a bomb while doped up with serum made from the blood of the previous Yozakura head, Shinzo drops his guard and takes blow after blow to buy time for Taiyo to clear out the building. Despite the fact that Nohmen was given muscles similar to Nanao's, Shinzo only ends up lightly bruised, which Nohmen hails as a testament to the Yozakuras' might.
• Trap Master: He and Shion are in charge of the Yozakura estate's defenses, preparing the security systems, lining the halls with booby traps, and turning the place into one giant Deadly Training Area.
• Traumatic Superpower Awakening: He's terrified of using his Blooming, "Destroy", after he left a sizable portion of a city in ruins in his berserk rage while using it. Because of this, it's his final resort and he'll only pull it out when he's completely out of options.
• Trigger-Happy: He teaches Taiyo to just shoot when he senses any kind of sudden presence or disturbance, which catches the sneering Sosuke off-guard.
• Try Not to Die: After being forced to use his Blooming against Kurosawa, an elite agent of Tanpopo, Shinzo asks him to try not to get killed by him.
• Walking Armory: Shinzo always carries a small arsenal of weapons with him on all of his assignments, pistols, rifles, rocket launchers, maces, and so on. His trash can is also lined to the brim with cannons, machine guns, missile launchers, and flamethrowers.
• Walking Shirtless Scene: He almost never has a shirt on, revealing his muscular arms, pecs, and abs.

Shion Yozakura

Shion Yozakura

Voiced by: Aoi Yūki (anime), Riku Hasegawa (vomic), Lynn (Special Drama)

A fiercely competitive Gamer Chick and the fourth child of the family, she's a hypercompetent hacker.

---

• Berserk Button: Cheating. She's furious with Taiyo when he inadvertently manages to fumble his way through her games with unintentional glitches that work in his favor, such as walking through an impassable wall or making his avatar invincible.
• Boring, but Practical: How she describes her own Blooming, Analyzation, to Kengo's. It doesn't do anything like mimic someone's neurons or mutate her body, it simply lets her crank her processing power to the limit to become a living supercomputer. When combined with her brainwave helmet, she can overwhelm virtually any kind of cyber security in moments.
• Challenge Seeker: Part of the reason why she converts operating systems to video games for her to beat is her desire for a challenge.
• Child Hater: Subverted. She claims to hate children as snot-nosed brats, but she quickly coos over Taiyo and Kyoichiro when they're turned into young children on two separate occasions. She also tries to play it cool with Alpha and Hifumi at first, but it's soon clear that she brought a massive bag of presents for them and tries to offer them millions of units of cryptocurrency as a gift.
• Color-Coded for Your Convenience: Her color is pink.
• Covert Pervert: When Kengo puts on porn at an inn, she starts watching it too. When Futaba scolds her for it, she claims she's watching it for educational purposes.
• Does Not Like Spam: While dining at an inn, she takes all of Shinzo's meat while dumping all of her vegetables on his plate.
• Don't Say Such Stupid Things!: Shion pokes Taiyo's eyes for saying that it's selfish of him to ask for the Yozakuras' help in finding out the true nature of his family's death.
  Taiyo: I know this is selfish of me... but could you all help me- [gets poked in the eyes]
  Shion: What are you talking about? You're family. Say something stupid like that again and I'll poke your eyes out.
  Taiyo: You already are!
• Famed In-Story: While all of the Yozakuras are famous, Shion is especially popular among the electronic warfare crowd, as her video game/hacking interface "Beast Crossing" brings together spies from around the world who ask her for advice. It's gotten to the point that she has her own fanclub, whose avatars she quickly torches in annoyance.
• Family Theme Naming: Like the rest of her siblings, she has a number in her name indicating the order in which they were born. Shion is the fourthborn and thus has "shi" (four) in her name.
• Foil: She's often paired up with Shinzo or Kengo to act as the snarky Straight Man to their jittery Nervous Wreck and energetic antics.
• Gamer Chick: So much so that she can hack anything by having a program convert its OS into a video game for her to beat to take control of it.
• Geek Physique: She's as slim as a gamer who doesn't get much exercise is expected to be, and Chapter 51 reveals that her Super-Strength is virtually nonexistent next to Shinzo's or Futaba's. This frustrated her when she was younger until she discovered her talent for hacking.
• Going Commando: Post-Time Skip, her outfit is a supercomputer shaped in the form of a long coat. But since it's charged via her body heat, she has to wear it against skin, leaving her wearing nothing underneath.
• Goggles Do Something Unusual: One of her gadgets is a pair of glasses that can work like binoculars or a magnifying glass to inspect things for traps. She gives them to Taiyo while he's on a date with Mutsumi at an aquarium.
• Good with Numbers: Her hacking specialty also means that she's a mathematical whiz, often spewing the likelihood of something happening via percentages based on her observations and the data she's collected. Her Blooming simply cranks her mathematical skills up to the max, which in tandem with her brainwave interface helmet lets her completely overrun Tanpopo's systems.
• Hollywood Hacking: Her brand of hacking has her convert a computer's OS into a video game for her to play and clear to get the computer to do what she wants.
• Information Broker: She runs a Animal Crossing lookalike called "Beast Crossing" that's actually a hub for spies and hackers like her. In it, she receives and shares information and tips with other spies like her.
• Jerk with a Heart of Gold: She's fiercely competitive and often comes across as bossy and aloof, chastising Shinzo for his indecisiveness and pressuring her family members into playing video games with her for days at a time. But she still values family above all and scoffs at Taiyo for thinking it's selfish of him to ask for help from her.
• The Leader: She's the head of her own "Team Shion", a group of hackers who use her Beast Crossing game to do everything from stopping black market dealings to disabling terrorists' servers.
• Serious Business: Shion is prideful of her hacking skills and uses a data-destroying torch to incinerate her own fan club when they try to flirt with her in her game.
  Shion: This game isn't for fun, and it's not a dating site! Casual players aren't welcome!
  Taiyo: Hardcore gamers are serious...
• Trap Master: She and Shinzo are in charge of the Yozakura estate's defenses, preparing the security systems, lining the halls with booby traps, and turning the place into one giant Deadly Training Area.
• Workaholic: Shion loves playing video games so much that it's not uncommon for her to pull five all-nighters in a row, foiling all kinds of crime and terrorism while managing her Beast Crossing game. Unfortunately for her family and friends, she sometimes press gangs them into playing along with her until they collapse.
• You Remind Me of X: She has a mentorly relationship with a younger spy named Kenji, another information and hacking specialist. Like Shion, Kenji lacks the physique of his family members. Unlike Shion, his extremely burly parents shame him for liking video games and hacking rather than honing his physical abilities. So Shion sympathizes with him and frees him when his parents lock him up for playing video games.

Kengo Yozakura

Kengo Yozakura

Voiced by: Yoshitsugu Matsuoka (anime), Ryuusei Ohtani (vomic), Takahiro Sakurai (Special Drama)

The cheerfully mischievous fifth child of the family, who can craft hyperrealistic disguises.

---

• Animal Motif: Cats. He's constantly dressed in cat-shaped onesie, has a small paw print on his face, and is generally seen as skeevy and mischievous.
• Becoming the Mask: Kengo's Blooming boosts his mirror neurons, allowing him to empathize with someone to the extent of knowing everything about their person, even their secrets. He uses this to convince Aonuma to surrender by invoking the memory of his Granny Hako.
• Brilliant, but Lazy: His unwillingness to do anything that bores him also means that he never does any of the clerical parts of spywork, namely paperwork and reports. He can't even bothered to put his clothes on unless he has to, lounging about completely naked in his filthy room without any signs of embarrassment.
• Color-Coded for Your Convenience: He's denoted by yellow.
• The Cynic: Beneath his playful and energetic exterior is a man incapable of taking others at the word. After all, if he can change everything about himself, what's to say that others can't?
• Everyone Has Standards: Kengo is mischievous and whimsical, but he's just as upset with Kyoichiro as the rest of the family when he draws on Taiyo's face while the latter in critical condition.
• Family Theme Naming: Like the rest of his siblings, he has a number in his name indicating the order in which they were born. Kengo is the fifthborn and thus has "go" (five) in his name.
• Gadgeteer Genius: The technology he uses for his disguises is entirely of his own design, and he has taught the other members of the Yozakuras how to use it as well even though he's still the best at it.
• Going Commando: He doesn't seem to wear anything under his onesie, simply grabbing it and dressing himself while challenging Taiyo and Mutsumi to a game of tag.
• Hidden Depths: His fight with Aonuma reveals that Kengo's disguise specialty has left him incapable of taking others at their word because of how easily he can change everything about himself. If he can change his voice, expression, and personality on a whim, who's to say that other people can't? The only people whose intentions he absolutely trusts are his family members, especially Taiyo and Mutsumi, whom he describes as wonderful idiots who are genuinely kind and willing to lay their lives down for others.
• Imposter Forgot One Detail: When he ropes Taiyo and Mutsumi into a game of tag to get him to do his paperwork, Kengo manages to tie up Taiyo and disguise himself as him. But just when it seems like he's won, Mutsumi cuffs him and reveals that Taiyo always opens the door for her to walk in first as his wife. Kengo deciding to step in first gives him away.
• Indy Ploy: While he does research for his missions in advance, more often than not he improvises as he goes. For instance, when pitted against Kyoichiro:
  Nanao: What's our plan?
  Kengo: Just whatever?
• Instant Costume Change: He can instantly change his appearance as well as other people's appearances with a single flourish, down to giving people bulletproof costumes, making them look taller or shorter than they actually are, and installing voice changing devices in said costumes.
• It Amused Me: He never does anything if he finds it boring and is willing to complicate missions just to get a kick out of it. He'll even be willing to do work pro bono if he finds it interesting. This is why he takes up the job he brings Taiyo along to, even though the suicidal girl Yukari couldn't pay up.
  Kengo: I don't care if it's a mission or anything else... I never do anything if it's boring!
• Latex Perfection: His disguises often consist of this. It gets exaggerated in how he can instantly disguise himself or others in latex suits in an instant. He can even make people look taller or shorter, equip them with voice changers, and even change their outfits.
• Master of Disguise:
  • Can instantly create scarily perfect disguises, full with fake skin and hair, on himself or other people. Kengo's disguises are so perfect that he replicates everything from the scent and voice to the number of eyelashes on their faces. Even Kyoichiro can be fooled by them at times, and Kengo loves to screw with him by taking on Mutsumi's appearance before piling on insults to make Kyoichiro curl up into a ball on the floor.
  • He has even used this offensively, quickly disguising an entire truck full of people as himself so they can't tell each other apart, causing them to attack each other in an attempt to find the real Kengo.
• Men Can't Keep House: Kengo is so lazy that he can't be bothered to clean his room, which is a total trash heap with stuff piled toward the ceiling. Not to mention the fact that he leaves weaponry and live explosives lying around for anyone to run into should they try to navigate it.
• Meaningful Appearance: He has long bangs that emphasize his shiftiness and ability to transform his appearance. It also hides half of his face most of the time, highlighting his talent as a Master of Disguise.
• Naked People Are Funny: He reclines in his trash-filled room while completely naked, and the entire scene is Played for Laughs.
• Proud Beauty: He's proud of his Pretty Boy good lucks and waxes poetic about how beautiful he is. Ironically, his specialty involves covering it up to resemble other people.
• Trash of the Titans: Kengo's large bedroom is filled to the brim with trash, weaponry, explosives, and paperwork he hasn't bothered to fill out.

Nanao Yozakura

Nanao Yozakura

Voiced by: Yumi Uchiyama (anime), Kaho Saida (vomic), Yukiyo Fujii (Special Drama)

^{Click here to see him in School Mode}

The sweet and gentle (but enormous) youngest brother, adept at creating drugs and medicine of all kinds. Hides his face with a bucket.

---

• Acquired Poison Immunity: While all of the Yozakuras have this, Nanao's body is uniquely suited to decomposing toxins and bioweapons. His body is able to render them completely harmless within a few hours, but during this time he becomes incredibly sleepy and must be rescued to keep him from getting captured.
• Adaptive Ability: Nanao's body naturally reinforces itself and adapts to external stresses. This is why his Acquired Poison Immunity is stronger than the other Yozakuras, in addition to being more resistant to heat and damage.
• Adorably Precocious Child: At least in School Mode, Nanao is soft and baby-faced, but carries himself with a level of maturity that makes his older brothers Kengo and Kyoichiro look downright childish by comparison. He's still more than willing to use his looks to get the lucky seat at an inn though.
• Badass Adorable:
  • He's exceedingly kind-hearted, but also a trained superspy and a genius doctor who hides his face in a bucket. The adorable part becomes even more pronounced in his "School Mode", though he notably loses access to his Super-Strength during this time unless he forces himself to mutate again.
  • That said, he's not above using his cute looks in School Mode to manipulate others, using Puppy-Dog Eyes on Shinzo to get the lucky seat by the window.
• Beware the Nice Ones: He's by far the sweetest member of the Yozakuras, but he's just as fiercely protective of family and once punches Kyoichiro for bullying Taiyo before demanding him to apologize.
• Big Eater: While on vacationing at an inn, the Yozakuras are all on their first plate of food... except for Nanao, who has already dug through 50 heaping bowls of rice and cheerfully looks forward to dessert while the innkeepers bring him more and more food.
• Big Little Brother: Despite being the youngest of the Yozakuras, Nanao towers over all of them, even his eldest brother, Kyoichiro. It's especially noticeable when he's in the same room as Taiyo and calls him "big brother".
• Bizarre Human Biology: His Yozakura talent manifests in his body's ability to naturally mutate into a stronger and more resilient form that adapts to most kinds of danger and stimuli. In addition to having a powerful immune system that can destroy most bioweapons simply by consuming it, he is able to synthesize drugs within his own body and vomit them up as egg-shaped pills later. It's also implied that he can force parts of his body to grow at will given the color spreads, and his fingernails can distend into claws.
• Blessed with Suck: His Yozakura talent is "Immunity", causing his body to naturally reinforce itself and neutralize toxins. While this grants him incredible strength, stature, and the ability to eliminate bioweapons simply by eating them, his freakishly large body has made him feel isolated from normal people and he has to shrink himself down to avoid unwanted attention. He laments that the drug he made will soon become completely ineffective on him and he'll have to withdraw from school at his current rate.
• Body Horror:
  • His "normal form" is actually his body's natural inclination to reinforce itself and mutate into a stronger form, resulting in his towering and hulking physique. Although he's created a drug to shrink himself down to a more normal size so he can attend school, his growing tolerance for it causes the suppressed body mass to surge up and out like something out of AKIRA. It's implied that this is the reason why he wears his bucket: to avoid horrifying other people with his strange growths.
  • The medicine he uses to suppress his transformations can also cause them in other creatures, turning the normal python Basilisk into a grotesque beast large enough to swallow someone whole. It's implied that Basilisk is terrified and in pain the entire time.
  • While motion sick in the car, he accidentally barfs up the drugs he's been trying to synthesize inside his body. It looks freaky enough that Taiyo asks if he's a Namekian.
• Bruiser with a Soft Center: He's a sweet, caring person but also shy enough to (try to) hide behind Mutsumi when he first meets Taiyo. He also has Super-Strength and can flip over sixteen-wheelers without an issue.
• Characterization Marches On: He's initially depicted as incredibly shy and somewhat meek, trying to hide his giant body behind Mutsumi when first meeting Taiyo. Nanao never showcases this level of meekness again, and is in fact quite sociable when shrunken down in School Mode.
• Color-Coded for Your Convenience: Cyan compared to Mutsumi's deep blue.
• Day in the Limelight: The "Nanao's Medicine" story arc sheds light on his ability and how it has affected his ability to socialize with people outside of his family.
• Dissonant Serenity: Even as his body contorts itself in Body Horror, Nanao is able to speak casually and cheerfully even when the extra body mass has completely immobilized him.
• Does Not Know His Own Strength: This is normally Averted due to his genius and talent. But when his mutations go out of control after curing Basilisk of its own mutations, even a light brush turns into a hard slap that sends Taiyo flying. Even the amount of strength he normally uses to precisely inject medicine becomes enough to pierce right through Taiyo's hand.
• Eat the Bomb: His response to bioterrorism is to eat whatever samples he can find and let his immune system detoxify them until they're destroyed and harmless. The only downside to this method is that he becomes sleepy while this is happening, forcing another of the Yozakuras to pick him up lest he's captured or killed.
• Exotic Eye Designs: After taking off his bucket, it's revealed that Nanao's eyes have multiple concentric rings and one of them has black sclera.
• Expressive Mask: The scribbles on his bucket apparently imitate his facial expressions.
• The Faceless: His face is always hidden by the bucket he wears on his head. He finally takes the bucket off his head when he's shown going to school, but not before he shrinks himself down to a more normal size.
• Family Theme Naming: Like the rest of his siblings, he has a number in his name indicating the order in which they were born. Nanao is the seventh and thus has "nana" (seven) in his name.
• Genius Bruiser: He's strong enough to flip over a truck with little effort, but also a medical supergenius, handling everything from physicals to pharmaceuticals, including a cure for the common cold.
• Gentle Giant: Towers over everyone, but is overall the nicest sibling, as well as The Medic.
• Healing Potion: He developed a special drug that rapidly accelerates healing to the point that a mere whiff of it can cure a cold. But overuse will cause the body to melt.
• I Am a Monster: His bodily mutations make him feel different from "normal human beings" and he believes his desire to be able to have an average school life is a fleeting delusion at best. It takes Taiyo to tell him that he is a normal person at heart to restore his own belief in himself.
• Iconic Item: He's almost always carrying his bucket around outside of school when he isn't wearing it on his head.
• I Just Want to Be Normal: Downplayed. He loves his family and the family business, but he also wants to go to school and later college to socialize and be as normal as he can be. Unfortunately, he's almost grotesquely muscular and three meters tall because of his own genetics, making him feel isolated from other "normal" people. Worse, the drug he made to shrink himself is losing effectiveness and he'll eventually be forced to withdraw from school whether he wants to or not.
• Labcoat of Science and Medicine: Is almost always wearing a labcoat, indicated his medical specialty.
• Luminescent Blush: He has a crush on Rinne Kitasato, the president of the Biology Club. So when she tries to assess Nanao's temperature by pressing her forehead against his, he gets embarrassed and starts heating up to the point that steam starts coming out of his head.
• The Medic: He's in charge of treating everyone's injuries and can administer drugs that do everything from giving someone an instant energy boost to dulling their pain. Even when caught in a life-or-death situation, he doesn't mind dying if it means he gets to treat his siblings' wounds.
• Mundane Utility: The Yozakura boys start a contest to see who can last in a sauna that goes up to 300 degrees the longest, with the winner getting fruit-flavored milk. Nanao cheats to win by switching back to his resistant body halfway through the competition, switching back once it was over.
• Nice Guy: He stands out as the nicest of the Yozakuras overall, showing the greatest amount of concern for Taiyo's well-being next to Mutsumi and never putting him through the grief the others do.
• Psychoactive Powers: He returns to his mutated, hulking body faster when he's agitated and has to calm himself down to lower the chance of hulking out in class.
• Replacement Goldfish: Nanao bears a striking resemblance to Taiyo's deceased little brother Hikaru. So hearing Nanao's struggles to fit in and live a normal school life quickly moves Taiyo to tears and gets him to start doting on Nanao like he did with Hikaru.
• Sleep-Mode Size: He developed a drug that shrinks him down to a size more suitable for someone his age, making him shorter than both Taiyo and Mutsumi when he normally towers over them. However, it's becoming harder and harder for him to maintain this "normal" appearance, and he needs regular injections of his drug to avoid hulking out in class. By the time Taiyo hears about it, he needs to get the shot multiple times a day, even during class.
• Stealthy Colossus: Despite being three meters tall and incredibly muscular, Nanao is able to be just as stealthy as anyone else. Then it's subverted in his daily life, as he has to inject himself with a drug to shrink himself down, lest his massive size draw unwanted attention at school.
• Super-Strength: His hulking physique grants him enough strength to tip over trucks with ease. A single punch leaves a crater in the floor.
• Survival Mantra: Nanao recites his own genetic code when he needs to calm himself down.
• Teen Genius: Nanao has developed a variety of drugs, including a cure for the common cold, and is a fully trained doctor despite his age. He's so intelligent that he has completely memorized his own genetic sequence^note a list of 3 billion base pairs and uses its base sequence as a Survival Mantra.
• Vocal Dissonance: He has the voice one would expect from someone his age despite being a three-meter-tall colossus in the vomic and sound dramas.
• The Worf Effect: Nanao is the most visibly roughed up by his opponents during the Yozakuras' raid on Kawashita's laboratory. He's subjected to Cold-Blooded Torture and is visibly beaten and left in a collapsed heap on the floor. Even still, he refuses to give up and lasts long enough for The Cavalry to arrive before deciding to activate his Blooming now that he has enough breathing room to do so.
• Younger Than They Look: Would you believe this massive, hulking man is actually the youngest of the Yozakuras? It's Played for Drama when it's pointed out that a three-meter-tall high schooler would draw heads, forcing him to develop a drug to shrink himself down to a normal size. And when that drug stops working, it will mean that he won't be able to attend school or college the way he always wanted to.
• Your Size May Vary: The first time we see Nanao in School Mode, he's just a head shorter than Taiyo and Mutsumi. The next time we see him shrunken down, he comes up to Taiyo's waist. Justified by how Nanao has been upping the dosage on his shrinking medicine to accommodate his increasing tolerance.

Goliath

Goliath

Voiced by: Yoshitsugu Matsuoka (anime), Mitsuteru Nagato (vomic)

^{Click here to see Goliath's full size}

The Yozakura family dog. He's a ferocious little thing.

---

• Action Pet: When he's finally let outside to stretch, it's revealed that Goliath is a force to be reckoned with in his own right. He's fast enough to outpace bullet trains and run on water while being strong enough to barrel through a steel door. His tail alone swats Taiyo hard enough to leave a person-shaped crater in the floor.
• Amplified Animal Aptitude: Goliath is clearly smarter than a normal dog, recognizing a bomb on sight and immediately rushing to shield Mutsumi and some nearby kids from the blast with his own body. He's also apparently able to lead criminals into custody after kicking their asses.
• Angry Guard Dog: Goliath is never seen not snarling and is usually tearing up paper when he isn't lunging at an aggressor, whether they're an intruder or Kyoichiro being unreasonable.
• Ironic Name: A dog named Goliath is a tiny-looking dog the size of a pomeranian. Later subverted when it's revealed that this is Goliath's Sleep-Mode Size, and when he finally gets to "stretch out", he's the size of a great dane. When he's truly pissed, he can become large enough to easily carry a fully grown man in his mouth.
• Jerkass Realization: Goliath is initially aloof towards Taiyo and swats him into the ground for daring to touch his leash. But after seeing Taiyo shield him and Mutsumi from a bomb blast, Goliath tosses Taiyo onto his back while giving him a huff of approval.
• Lightning Bruiser: Fast enough to outpace a bullet train, tough enough to withstand a bomb blast, and strong enough to leave people in craters and smash through steel walls without slowing down.
• Long-Lived: Goliath is an Okami dog, which were bred for exceptional hardiness and longevity. He's at minimum around a century old, as his original owner was Mutsumi's great-great-grandmother.
• Scarily Competent Tracker: One whiff of a detonated bomb's scent is enough for Goliath to pinpoint the bomber's location and then rush over to eliminate them.
• Sleep-Mode Size: While indoors, Goliath keeps himself constrained. But when finally let outside for a walk, he stretches out from the size of a chihuahua or pomeranian to the size of a great dane.
• Undying Loyalty: Goliath has been with the Yozakuras for generations and will only allow the current head of the Yozakuras to walk or ride him, brutally crushing anyone else who so much as touches his leash. He warms up to Taiyo after seeing him shield him and Mutsumi from a bomb meant for her, letting him ride on his back for the rest of their trip.
• Urine Trouble: Goliath pisses all over Kyoichiro after Kengo gets him to curl up in a fetal position on the floor.
• The Worf Effect: Even after stretching to his full size, Goliath is taken down in one punch by the head of the Tanpopo forces assaulting the Yozakura estate to demonstrate how dangerous someone who is compatible with Hazakura is.

11th Generation

Alpha and Hifumi Yozakura (Post-Time Skip spoilers!)

Alpha on the left, Hifumi on the right

Taiyo's and Mutsumi's twin children, born during the Time Skip. Alpha is an incredibly intelligent child who struggles to be taken seriously, while his sister Hifumi is frivolous but extremely clingy to her brother.

---

• Adorably Precocious Child: Alpha is far more intelligent than his father and could be an amazing spy if he wanted to be. But all he wants to do is live a normal life and struggles to be taken seriously. He researches the preschools he wants to attend and is already planning for college and his first career. He then whines that Taiyo is getting snot all over his shirt through his Inelegant Blubbering over what a good child Alpha is.
• Annoying Younger Sibling: Inverted. Hifumi is the playful, irresponsible older sibling to Alpha's studious, younger sibling. He's tired of her antics constantly getting them expelled from school when he just wants to study and lead a normal life.
• Aww Look They Really Do Love Each Other: Alpha screams that he hates Hifumi for all the trouble she puts him through, from getting expelled repeatedly to leaving her blocks all over the floor to being smothering in her affection for him. Despite this, Hifumi knows that Alpha doesn't mean it and all of her actions are done out of genuine love for him. When a mercenary comes after the both of them, they risk their lives for each other without hesitation despite being out of their depth.
• Badass Adorable: Alpha and Hifumi are both both four years old and cute enough that all the Yozakuras dote on and coo over them. They're also more than capable of taking care of themselves and can even give their aunts and uncles a run for their money.
• Big Sister Instinct: Hifumi has gotten both her and her brother expelled from schools on three different occasions due to retaliating against people badmouthing Alpha behind his back, which she hides from him because she knows he'll only blame himself for it. When a mercenary comes after the both of them, Hifumi throws Alpha into the thicket without hesitation to hide him before facing the mercenary alone. When Nii reveals that Asa wants Alpha killed on-sight, Hifumi's protective feelings toawrd Alpha are so strong that she instantly awakens her Blooming before going on a rampage.
• Birds of a Feather: She quickly gets along with her uncle Kyoichiro due to having similarly obsessive affection for their respective siblings. However, this is subverted when Kyoichiro's attempts to bully Taiyo with death threats make Alpha cry, upon which Hifumi declares she hates Kyoichiro for his actions.
• Book Dumb: According to Alpha, Hifumi sucks at math, but somehow always manages to get the ratio for his favorite apple pie correct. She's also able to cut an apple pie into perfectly even wedges and manages to sneak out of the house without either of her parents noticing. Later on, she holds her own against an ex-gold rank spy for a while by swinging her yoyo around with lethal accuracy. Her opponent describes her skills as comparable to that of the top percentile of silver rank spies.
• Child Prodigy:
  • Alpha has already published theses and created patents at the tender age of four. His former principal describes him as the student with the highest marks in the country and he's developed locks so complex that Taiyo struggles to pick them despite being in the spy business for over five years. While Hifumi is Book Dumb, she's implies to be incredibly athletic and crafty in her own right, having strung up a kid who wanted to bully Alpha from atop a statue that requires a ladder for adults to reach. Alpha also recalls a time where she dived into the ocean to catch a great white shark because she knew he likes them.
  • According to Mutsumi, both Alpha and Hifumi have been able to walk and talk since they were one month old. Furthermore, they understand complex games and tasks like chess.
  • A mercenary who was once a gold rank spy remarks that even without proper spy training, the Yozakura twins would rank in the top percentile of silver rank spies given their current abilities. By comparison, their father only reached silver rank with months of training, unlocking his Blooming, and then his Profuse Blooming of 10,000 Flowers.
• Clingy Jealous Girl: Hifumi loves Alpha so much that she gets jealous when other women enter his life. Seeing Futaba constantly outdo her attempts to make Alpha happy drives Hifumi crazy. She soon challenges Futaba to a fight in hopes of proving herself the better older sister (even though Futaba is their aunt).
• Cute Bruiser: Hifumi is a cute four-year-old who also happens Yozakura Super-Strength, smashing through steel with her favorite yo-yo. Futaba shows that with practice, Hifumi could even part the seas and sink submarines with sufficient control and technique. This goes even further with her Blooming, which turns her into a seemingly endless fountain of someinine energy. She can drill through bedrock fighteningly quickly and force Kyoichiro to use his Blooming to cancel out hers.
• Death Glare: When someone makes Alpha cry, Hifumi can exude intense Killing Intent along with a disturbing glare scary enough to cow even Kyoichiro. Taiyo compares Hifumi's rage to that of an angry Yozakura with their Blooming active.
• Disproportionate Retribution: Bad-Alpha, Alpha's Split Personality, is prone to coming out and wreaking vengeance when Alpha is under severe duress. When a bully threw his notes in the water, Alpha programmed every appliance in the bully's house to explode. He also crashed the airplane of the CEO who caused Alpha's favorite game company to fail. But while Bad-Alpha is The Unfettered, Alpha remembers what he did once his rage subsides and feels awful about it.
• The Dividual: Discussed. Alpha and Hifumi have been together all their lives and have always worked together even when they're arguing. To prevent them from becoming overly reliant on one another, the other Yozakuras decide to put them on different teams to train them and prepare them for the Yozakura Frontlines mission.
• Family Theme Naming: Alpha refers to the first letter of the Greek alphabet and is often used to indicate the first of a series. Hifumi meanwhile can translate to "one, two, three". This reflects how they're the first of a new generation of Yozakuras. In Alpha's case, it also alludes to how he also possesses the capability of being clan head like his sister, a role that has normally been relegated to the women in the family.
• Foolish Sibling, Responsible Sibling: Alpha is the responsible sibling. He's determined to go to a good school to land a good, normal job and earn a decent paycheck. His Super-Intelligence ensures that he has the highest grades in the entire country and he's already making strides toward securing his future through patents and theses. Hifumi is the foolish sibling, having no interests other than playing games with her brother and trying to make him happy. She acts out at school when others try to bully Alpha, leaves her toy blocks all over for people to step on, and is described as sucking at math.
• Force and Finesse: Hifumi is the Force to Alpha's Finesse. Hifumi approaches the world as a child would: blunt and to the point. She constantly tries to overwhelm he foes with brute strength and the crushing force behind her Killer Yo-Yo. Alpha is much more intelligent and Wise Beyond Their Years, preferring to use a Gadget Watch and analyzing his surroundings to best make use of them.
• Gadgeteer Genius: Alpha shares his aunt's and uncles' talent for engineering, having published several theses and patenting numerous inventions of his own at the tender age of 4. He apparently designed the locks for his own room, which are so complex that Taiyo, an experienced spy at this point, has great trouble picking them.
• Gadget Watch: When pushed into a corner, Alpha fights with his "Alpha Watch". It's capable of producing a disproportionately long clawed hand to grab people and things. It can also hack into pay phones to send GPS signals and shoot electric beams not unlike his father's signature gun, Yae.
• Goo-Goo-Godlike: Both Alpha and Hifumi are noted to have enormous potential as spies, so much so that Asa wants them dead on sight. This is demonstrated when Hifumi awakens her Blooming, forcing Kyoichiro to use his own Blooming to cancel out her uncontrolled someinine energy before it destroys her.
• Guys Smash, Girls Shoot: Inverted. Hifumi is the bruiser between the two of them, smashing things with her Killer Yo-Yo and superior Yozakura strength. Meanwhile, Alpha is an intelligent hacker who fights with a Gadget Watch.
• Heroic Self-Deprecation: Hifumi blames herself for all of Alpha's troubles, especially knowing her actions keep getting them both expelled. When a bounty is placed on her head, she resolves to run away from home, believing that she's more trouble to her family than she's worth.
• Hollywood Tone-Deaf: Like her mother, Hifumi is a dreadful singer whose singing voice can be used as a sonic weapon that has professional spies clutching their ears in agony. Only Alpha, Mutsumi, and Kyoichiro can withstand it without protection, with Taiyo needing to use his Blooming on his ears to avoid injury.
• Idiot Hair: Both of them share this trait with their father Taiyo. Alpha has a single curl that's angular and rigid, reflecting his serious personality. Meanwhile, Hifumi has multiple curls throughout her hair, which shows that she's Book Dumb and far more frivolous than her brother. Alpha even lampshades this shared trait with Taiyo when bickering with Lando.
• I Just Want to Be Normal: Despite being a Child Prodigy of a spy lineage, Alpha wants nothing to do with the spy business and just wishes to experience a normal life. This is also to ensure Hifumi doesn't put herself in more danger for his sake. It's then subverted when a bounty hunter comes for his and Hifumi's heads, forcing Alpha to realize that his life will never be "normal" as a member of the Yozakuras. He then prepares to ask for training before his parents reveal that they're going on a road trip to spy school.
• Intelligence Equals Isolation: Alpha is implied to be the subject of Tall Poppy Syndrome, leaving him utterly friendless. His classmates and their parents believe he cheats to achieve all he has when he really is that smart. This leads to Hifumi's outbursts where she attacks those who would bully him to soothe their wounded egos.
• Kid Hero: Double Subverted. Alpha has no intention of getting involved in his family's fight against Asa, the true founder of the Yozakura family, understandably believing himself and Hifumi to be woefully underprepared. But Hifumi insists on joining the fight so Alpha doesn't have to be locked in a Gilded Cage for his safety. Despite his reluctance, Alpha agrees to help Hifumi in her quest to get permission from the other Yozakuras to join the fight when they feel the twins are ready.
• Killer Yo-Yo: Hifumi's preferred weapon is her yoyo, made from the Yozakuras' trademark sakuragane alloy that makes it incredibly strong and hard. Its line is made with thread from Kyoichiro's Steel Spider. Combined with Hifumi's Yozakura Super-Strength, it acts as an extremely deadly weapon capable of smashing solid steel when swung around with lethal accuracy.
• Locked Out of the Loop: While they know about the Yozakuras' Family Business, Alpha and Hifumi were never told about the existence of their aunts and uncles until a bounty was placed on all of their heads. Taiyo and Mutsumi explain that they knew the twins would be curious and seek out their relatives if they knew about them, so they had to be kept in the dark for their safety.
• Men Can't Keep House: Inverted. Alpha's room is neat and organized (a trait he shares with his father), while Hifumi leaves her toy blocks all over the floor no matter how many times Alpha complains about it.
• My Suit Is Also Super: Kyoichiro sewed the twins' clothes himself to the Yozakura family standard, making their outfits bulletproof and knifeproof.
• Odd Name Out: Alpha is the only member of the Yozakura family to have a Greek name when the rest of his family members, including his twin sister, all have fully Japanese names.
• Perpetual Smiler: Hifumi always has the same smiling expression on her face no matter how she seems to actually feel in the moment.
• Photographic Memory: While resting on a bench with Kyoichiro, Alpha says that he remembers his uncle's scent from the time Kyoichiro snuck back home to meet them. Even though the twins were no more than infants at the time, Alpha says this is one of his first memories and that he finds Kyoichiro's scent comforting because it reminds him of Mutsumi's.
• Polar Opposite Twins: Alpha is serious, incredibly studious, and Wise Beyond Their Years. Hifumi is frivolous, Book Dumb, and prone to violence when it comes to protecting her little brother. They even have opposite eye colors, with Alpha inheriting Mutsumi's blue eyes while Hifumi inherited Taiyo's red eyes. Despite his exasperation with Hifumi's antics, Alpha would like nothing more than to live a normal, peaceful life with her.
• Seers: Alpha's Blooming lets him see multiple possible futures. The first time he uses it is rather traumatic since the first future he sees is one where he's surrounded by the dead bodies of his entire family.
• Shared Family Quirks: Both Alpha and Hifumi share a lot of traits with their parents, aunts, and uncles.
  • Alpha's aptitude for engineering and desire to live a normal life makes him similar to Shinzo and Nanao. His intelligence leads him to be antisocial and competitive like Shion and he shares her penchant for Hollywood Hacking. His tendency to be his sister's minder resembles Futaba's tendency to rein in Kyoichiro. Like his father Taiyo, Alpha desires nothing more than the safety and security of his family, working extremely hard to secure his and Hifumi's futures. He also has a Split Personality that's dangerously unhinged like his maternal grandfather, Momo.
  • Hifumi takes most strongly after Kyoichiro, given her clinginess to her brother Alpha and willingness to use violence to protect him, even using a Killer Yo-Yo constructed with the same material as Kyoichiro's Steel Spider. But she has Super-Strength like Shinzo and Nanao, a tendency to hide her feelings of inadequacy behind a strong front like Futaba, and an inability to keep house like Kengo. Her tendency to hide the times when she's serious behind silly actions is much like her great-grandfather Ban. Like her father Taiyo, Hifumi suffers from confidence issues over her feelings of worthiness toward her family. Lastly, like her mother Mutsumi, Hifumi desires to keep her family together and enjoys cooking for her loved ones.
• Sibling Team: Alpha and Hifumi are practically inseparable and far more formidable together than they are apart. As their family continues to teach them about being spies, the twins' combined firepower shocks even Kyoichiro when the twins come up with devastating Combination Attacks.
• Smart People Play Chess: Despite being four years old, both Alpha and Hifumi know how to play chess. Hifumi regularly pesters Alpha to play it with her, while he complains that he already beat her in ten out of eleven games. It's implied that Hifumi is smart enough to beat him more often than that, but she just enjoys watching him win even as he exhausts himself playing against her.
• Split Personality: Like his maternal grandfather, Alpha has a second personality nicknamed "Bad-Alpha" by Hifumi. During this state, his normally angular Idiot Hair becomes curvy and his eyes become creepy concentric circles like Momo's. Bad-Alpha is The Unfettered, which makes him far more dangerous in this state. But since there's continuity of memory between these personalities, Alpha feels awful about his actions afterward. The only way to shock him out of it is to show him the one thing he hates most: frogs.
• Stepford Smiler: Hifumi wears a perpetual smile, but secretly nurses a great deal of self-loathing over the trouble she causes Alpha. She wonders if she's more trouble to her family than she's worth and runs away out of fear of causing her family even more problems when she discovers a bounty on her head.
• Strong Family Resemblance: Alpha looks quite a bit like a younger, dark-haired version of his paternal uncle Hikaru, save having Taiyo's Idiot Hair. Meanwhile, Hifumi resembles a younger female version of her maternal uncle Kyoichiro, who she shares a lot of traits with.
• Super-Intelligence: While it's more pronounced in Alpha's case, both twins were walking and talking since they were a month old. Alpha and Hifumi regularly play chess at four years old and have a conversational understanding of French, letting them navigate Paris on their own and crack codes designed for seasoned spies. Alpha is also noted to have the highest grades of any child in the entire country and is an already gifted engineer and programmer. He can even force Shion to take him somewhat seriously in a hacking contest despite the vast difference in experience between them.
• Superpowered Evil Side: Bad-Alpha, Alpha's Split Personality, thinks faster and is far more ruthless than he normally is. He's able to manipulate multiple tendrils from his Alpha Watch simultaneously and quickly overwhelm Shion's security that previously stumped him. He's also The Unfettered in this state and is prone to Disproportionate Retribution, such as crashing the airplane of the CEO who caused his favorite game company to fail.
• Super-Strong Child: Even at age 4, Hifumi has no issues hoisting a fully grown great white shark out of the water or using her yoyo as essentially a long-ranged battering ram about to smash steel.
• Tears of Fear: Alpha cries a mix of these and Tears of Joy after his father arrives in a nick of time to save him and Hifumi from a mercenary after the bounty on their heads is made public. After a stressful night of trying to be the mature one to get him and Hifumi out of this situation, Alpha's sobbing is a reflection of both the fear he felt and his relief at being rescued.
• Trademark Favorite Food: Alpha loves apple pie, especially with extra sugar and butter. Hifumi tries to use it as a bribe to get him to play with her, but he's too angry with her to take her up on the offer.
• Twins Are Special: Kyoichiro notes that Alpha and Hifumi are the first twins in the Yozakuras' family history. Moreover, Kyoichiro believes that both twins possess the capability to become the clan head (especially more noteworthy with Alpha as all of the clan heads in the past have been female) while also possessing the Yozakuras' superpowers, making them truly unique.
• Why Did It Have to Be Snakes?: The one animal that Alpha absolutely despises is frogs, as every part of them creeps him out to the point of him frothing at the mouth. Even making a hand gesture that looks like a frog while making ribbit sounds will send Alpha into a panic. They're also the one thing that can snap Alpha out of his Bad-Alpha Split Personality.
• Wise Beyond Their Years: Alpha studies rigorously on his own time and researches what schools to attend in order to boost his future career prospects. He's also building his own finances with his own patented inventions and has already published theses even though he hasn't even graduated preschool. When he and Hifumi are attacked, Alpha's first thought is to hack a payphone to signal their whereabouts to their parents rather than try to take on the threat himself. This lets Taiyo reach the twins in a nick of time to save them from a messy fate.
• The Worf Barrage: Both Alpha and Hifumi are far from helpless and demonstrate their skills even while confused and fleeing for their lives from an ex-gold rank spy, who considers them comparable to the best silver rank spies. However, the difference in experience is apparent and their would-be kidnapper quickly subdues both of them, requiring Taiyo to come to the twins' rescue.
• Wrecked Weapon: Alpha's Gadget Watch is destroyed by the mercenary who comes to collect the bounty on them when Alpha tries to use it to defend Hifumi. It's later repaired and he uses it to defend himself from spies at Teiou Academy.

Previous Generations

Rei and Momo Yozakura

Rei and Momo Yozakura

Mrs. Yozakura

The mother and father of the Yozakura siblings. Both of them perished while on assignment years ago.

---

• Comes Great Responsibility: Mutsumi's mother explained to her that their blood contains a great power that can be used for terrible evil, but also for immense good. But such power cannot be used lightly, and using it for someone else means being willing to take on their suffering as well. Mutsumi remembers this advice when she injects her blood into Taiyo in a desperate attempt to save his life.
• Conditioned to Accept Horror: Like her children, Rei can say disturbing things with casual ease, like recording a video of herself to congratulate Mutsumi and Mutsumi's future husband years in advance because she knew she would likely die before she ever got to see the wedding.
• Deceased Parents Are the Best: Zigzagged. Both died some time before the events of the story. Rei is remembered fondly by her children and the sight of her in a secretly kept video makes Mutsumi cry Tears of Joy. But her husband is remembered as a good-for-nothing and apparently died in an explosion. Kyoichiro is in earshot of this, but does not react at the accusation. Then it's subverted when Momo is revealed to be alive and an agent of Tanpopo. However, it is later revealed Momo was also beloved by his children prior to his disappearance.
• Dissonant Serenity: The Yozakuras' version of Momotaro is scarily bloody, but her bedtime stories are comforting enough to her kids that Mutsumi instantly falls asleep hearing them while Futaba is delighted. Taiyo lampshades the disparity between the happy image and the story's actual content.
  Rei: The old lady's dagger gouged out eye after eye of the ogres...
  Taiyo: The heartwarming scene and the dialogue don't match!
• Family Theme Naming: Like her children and father, Rei shares a number name theme. Her name contains the kanji for zero (零) referring to her being the mother of the Yozakura siblings.
• Good Parents: Rei was beloved by all of her children, and all flashbacks pertaining to her frame her as the perfect mother who loved her children unconditionally and always knew what to say. Not much is known about Momo's parenting, but he taught Kyoichiro everything he knows.
• Parental Obliviousness: Inverted. Rei's well-aware of her family's quirks and correctly foresaw that Kyoichiro would try to murder Mutsumi's future husband in her wedding video recorded in the past.
• Posthumous Character: Both of them have been dead for years by the event of the story. Except, Momo is alive and is working for Tanpopo.

---

Ban Yozakura

Ban Yozakura

The former patriarch of the Yozakura family and the husband of its eighth head, Keiko Yozakura. His ability to infiltrate any facility and escape any restraint is only rivaled by his inability to keep his intel to himself and his love for flirting with younger women.

---

• Abnormal Limb Rotation Range: He's able to contort his skeleton to the point that he can fit inside Taiyo's schoolbag. It also means he can squeeze through any space so long as he can get his head inside.
• Armor-Piercing Attack: His Blooming allows him to imbue the same inflitration effect he possesses onto his bullets, allowing them to penetrate 1,000 meters of bedrock with ease and blast gaping holes into fortress walls.
• Badass Boast: When Kyoichiro wraps him up in Steel Spider to take him back to prison, Ban's response is to chuckle and welcome him to try.
  Ban: Heh... you certainly talk big these days. Don't forget who changed your diapers... [slips out the wires like an eel] Just try and stop me, young'un. [clicks his watch to drop a smoke bomb to vanish along with Taiyo]
• Bunny-Ears Lawyer: He's one of the world's greatest escape artists who has acquired tons of data from his work as a spy. He's also a flirtatious, cheerful, and goofy grandpa who instantly takes a shine to his new grandson-in-law and evades all of his attempts to stop him from leaking intel.
• Compact Infiltrator: A master Contortionist capable of infiltrating nearly any facility, he's so flexible that he can fold himself into people's handbags and drawers, introducing himself to Taiyo by sneaking inside his school bag. When Ban gets serious and activates his Blooming, he can even slip up Taiyo's shirt like a wisp and exit Taiyo's sleeve.
• Cool Old Guy: While he's treated with a bit of disdain by his grandson, Kyoichiro, Ban is a cheerful, friendly guy who is delighted to meet Taiyo and wants to take him out for a night of partying and drinking. He also hasn't lost his touch in his golden years, easily escaping Kyoichiro's steel wires and is still active enough to have countless bounties on him for all the information he holds.
• Escape Artist: He's infamous for his ability to escape any restraint and infiltrate any facility thanks to his ability to dislocate any joint in his body and his unusually flexible skeleton. Any prison is a Cardboard Prison for him and he only stays in it because he's asked to in order to work undercover and glean information from caged crooks.
• Establishing Character Moment: He's introduced hiding inside Taiyo's bag before resetting his skeleton, getting shocked by a startled Taiyo, and congratulating him on his marriage before handing him a massive wad of cash as a dowry. He then proceeds to evade Kyoichiro's attempts to restrain him before dragging Taiyo out to party, establishing Ban as a goofy, fun-loving but frivolous old man.
• Family Theme Naming: He shares the same number name theme as the Yozakura siblings. In his case, his name has "ba" (eight) in it, and he is the husband of the eighth head of the Yozakura family. His name is also homophonous to the Japanese word for "10,000", reflecting his advanced age and skills that put even his grandkids to shame.
• Foil: To his grandson-in-law, Taiyo. Ban is loose-lipped, goofy, and fun-loving in contrast to Taiyo's Only Sane Man personality. They also led self-destructive lives before meaning their wives, but Ban's happy-go-lucky semi-retirement is jarring next to Taiyo's increasing and almost obsessive zeal in protecting Mutsumi. Even their Blooming abilities are polar opposites. Ban's "Passage" enhances his already incredible flexibility to allow him to freely warp and manipulate his body to get himself and his weapons in any position he desires, while Taiyo's "Hardening" causes his body to prepare to take an attack head-on, hardening his cells and softening his joints to absorb and nullify it.
• Hand Cannon: Ban's preferred weapon is a regular-old pistol. But he's able to control everything about it down to the bullet velocity, riddling the ground with a circle of bullets in an instant. When he gets serious, a single Blooming-boosted bullet tears a hole the size of a truck in a fortress wall and parts the sea behind it even after it's mostly absorbed by Momo's own Winter Daphne technique.
• Happily Married: Despite his philandering, he's still head-over-heels for his wife Keiko. In fact, she's the only one who can catch him, as he wouldn't dare try to escape handcuffs that would blow her arm off too.
  Ban: [getting thrown into the back of a car] Let go of me! A life where I can't be with Keiko is no life at all!
• I Want Grandkids: Well, great-grandkids. He laments how prudish spies are these days and wishes Mutsumi and Taiyo would just give him great-grandkids to dote on already. After the Time Skip, Ban gets his wish.
• Loose Lips: His greatest flaw is his tendency to spout all of the classified information he knows just to impress the ladies. Kyoichiro hates him for this and calls him a failure as a professional.
• Obnoxious In-Laws: Subverted. While his antics exhaust Taiyo, Ban is immediately impressed by his new grandson-in-law's reflexes and devotion to Mutsumi and just wants to have fun and get to know him.
• Personality Powers: Ban is easy-going but highly mercurial, jumping from one thing to another at the drop of a hat and constantly goofing off. This is reflected in his ability to contort himself in any way he desires to infiltrate any location. Despite his goofy personality, he also has a deadly serious side. Which is shown by his ability to leave an enormous gaping hole in a fortress wall and part the sea with a single shot from his pistol.
• Retired Badass: Downplayed. He's still working as a spy for the family, being stuck in prison to get intel from whatever criminals he's housed with. Despite this, neither he nor his wife spend much time on the Yozakura estate anymore, to the point that the security system no longer recognizes him.
• Silver Fox: He's incredibly athletic and good-looking for a man his age. He remains popular enough to have girls swarm to him at bars, albeit this is partially because of his tendency to impress them by spilling top-secret information.
• Took a Level in Cheerfulness: Prior to meeting Keiko, Ban was a cold, aimless spy who approached everything with deadly seriousness as he had nothing else to do with his life. Their romance opened his heart and turned him into the goofy, fun-loving grandfather seen in the present. Ban's stories about himself remind Taiyo of his own withdrawn behavior before he married into the Yozakuras.

---

Keiko Yozakura

Keiko Yozakura

The Yozakuras' grandmother and Taiyo's grandmother-in-law. She's the eighth head of the Yozakura family prior to Mutsumi's mother.

---

• Cool Old Lady: She was the eighth head of the Yozakuras and as such was able to handle their superspy antics. Keiko also seems to be respected by her grandkids, unlike her husband, and is the one to rein him in after he causes Taiyo and the others trouble. A later chapter reveals she's able to use a sniper rifle with great accuracy.
• Friendly Sniper: A loving, genteel grandmother and wife who is also handy with a sniper rifle even while shooting from a moving helicopter.
• Happily Married: Despite her husband's philandering and prolonged stay in prison, she still has a loving relationship with him. She agrees to go on a date with him for old times sake before sending him back to prison to work. Taiyo hopes his relationship with Mutsumi will be as loving as Ban's is with Keiko.
• Posthumous Character: Subverted. The way Ban talks about her makes it seem like she's died, only for her to show up not long after he brings her up in conversation. Taiyo even lampshades this, noting that he never actually said she died.
• Supreme Chef: She's able to prepare food incredibly quickly and has Taiyo eat until he has a Balloon Belly in preparation for his final battle with Tanpopo.
• Women Are Wiser: She's significantly more serious and reasonable than her goofy husband, introducing herself as "this idiot's wife" and chastising him for making her miss a flight to England.
• Yamato Nadeshiko: Keiko is matronly, firm, kind, and supportive. As the eighth head of the Yozakuras, she was the anchor of the household. She even shows up in a kimono compared to the western-style dress of her husband and grandkids.

---

Tsubomi Yozakura

Tsubomi Yozakura

The founder of the Yozakura bloodline and the original source of the family's innate superpowers.

---

• Blessed with Suck: She hates her powers and the bloodline she created. While her descendants gained incredible superpowers, she had cherry blossom branches growing from her eye, head, arms, and legs and was experimented on by the Japanese government in hopes of creating Super Soldiers to turn the tide of World War II. It's also indicated she hates them even more because of what her father became as a consequence of her bloodline.
• Body Horror: Cherry blossom branches seem to be growing out of her arms, head, legs, and eye. Given that Kawashita turned into a giant tree-human hybrid with the power of Yozakura blood, it's implied that these branches are made of flesh.

Ayaka Kirisaki

Voiced by: Mariya Ise (anime)

• Berserk Button: Ayaka isn't thrilled when Mutsumi calls her a "manhunter".
• Clingy Jealous Girl: She can't do anything to hurt her because of her deal with Kyoichiro, but nonetheless expresses immense jealousy and hurls insults at Mutsumi. She stops having this attitude towards her later on, but also takes on this role on her behalf when she suspects that Taiyo is cheating.
• Closet Key: Taiyo notes that something had awakened in her after she falls for Mutsumi.
• Cuddle Bug: She clings to Taiyo and Mutsumi after they're away for long periods of time to "recharge her tank".
• Depraved Bisexual: She's in love with both Taiyo and Mutsumi and is a vicious Yandere assassin.

• In Love with the Mark: She was in love with all of her marks, and this love is what drives her to try to kill them due to some Insane Troll Logic surrounding what she thinks love is.
• Lacerating Love Language: A spy whose Insane Troll Logic leaves to to fall In Love with the Mark every single time. She believes that she can only show her love by killing her targets and her "love" makes her the one most worthy of killing them.

• No Sense of Personal Space: Ayaka is very clingy and is completely shameless about following Taiyo into the bathtub.

• Single Woman Seeks Good Man: A lot of her reasons for loving Taiyo involve his altruistic qualities.

Ai

Ai

A small girl under the care of Mizuki, one of the Nijibana Flowers. She possesses oddly familiar ears and size-shifting abilities.

Following the events of the Tampopo raid, Ai is put into the care of the Yozakura family, with Taiyo and  Mutsumi more or less treating her as their adoptive daughter.

---

• Abusive Parents: Her biological mother constantly beat her up until she was finally murdered by Mizuki to retrieve Ai for Tanpopo.
• Happily Adopted: Due to her former abusive homelife, Mizuki is a far better Parental Substitute who cares for her despite harshly disciplining her. She's later taken in by the Yozakuras, who all dote on her and try to acclimate her to normal society. Of course, since they’re a pretty weird family themselves, "normal" is relative, which can lead to comical situations (see Too Smart for Strangers below).
• Lightning Bruiser: She has all of the abilities of an okami dog, including its Sizeshifter powers, obscene strength and speed, and its keen sense of smell. She has no problems outpacing a moving train or carrying things several times her size.
• Little Bit Beastly: She has furry paws and dog ears due to having her DNA mixed with an Okami dog's and she's shown to be able to shift between forms at will.
• Pint-Sized Powerhouse: Due to being spliced with the DNA of an Okami dog, Ai possesses disproportionate strength for her size, able to bat Taiyo down the length of a train car with ease and damage Nanao.
• Too Smart for Strangers: Taiyo and Mutsumi teach Ai to hurl strangers who try to approach her away. When Taiyo approaches her in disguise, she tosses him into the nearest bush. Mutsumi can't help but cheer that their stranger danger lessons have stuck with Ai.
