Taimanin Task Force and Associates (Supporters) | Villains | Other Characters
This is a partial character sheet for Action Taimanin. Subjective trope and audience reactions should go on the YMMV page.
Taimanin Task Force
A group of a handful of Demon Slaying ninjas from the Gosha Village, but also has members from the UFS, Chinese Union, even demonic hybrids and freelancers. They focus on dealing with terrorist attacks caused by international syndicates along with the forces of the Dark World. open/close all folders
In general
- Amazon Brigade: Although the main character is male, and at least some of his classmates are too, all playable characters and nearly all unlockable Supporters are female.
- Badass Crew: The Taimanin task force is a group comprised of super-powered, Demon Slaying ninja, Cyborg super-soldiers from the UFS, and the odd demonic defector who's chosen to live with humans peacefully rather than try to dominate or destroy them.
- Clothing Switch: A good deal of the each character's craftable outfit consist of giving them the base costume of another character, such as giving Felicia Kurenai's costume and inverse, giving eleonor Kirara's outfit, and so on.
- Ninja Brat: Some of the playable Taimanin and supporters like Sakura and Yukikaze are high school freshmen, and the youngest may still be in Middle School, but they're still as dangerous as the adults like Asagi or Murasaki.
Main Team
Bar Kotaro, all the characters in this category are playable.
Kotaro Fuuma
Kotaro Fuuma
Voiced by: Wataru Hatano
The main character. Last scion of a diminished ninja clan whose father attempted to rise in rebellion and was almost entirely destroyed. Only Kotaro, and a handful of close retainers, including his half-sister, remain, and they survived by remaining loyal to Asagi and throwing in their lot with them.Kotaro's Ninja Art is dormant, leaving him poorly-suited for combat compared to his superhuman teammates, but he is a clever and capable organizer, and was placed in command and control of the Task Force. He monitors missions through his command drone, and generally serves as support personnel in the field.
- Accidental Pervert: Kotaro sometimes ends up in situations that would make him look like a perverted creep even if he didn't mean to, such as accidentally losing his balance and touching Serika Tachibana's thigh and stomach.
- Adaptation Explanation Extrication: In RPG, there's eventually an (admittedly convoluted) explanation for why Kotarou never awakened his Taimanin Art, and it's never made clear in Action. Then again, that Kotarou also ended up with a completely different powerset that this Kotarou doesn't seem to have.
- Adaptation Relationship Overhaul: In this timeline, Kurenai and Kotaro are childhood friends, and his romantic relationship with his half-sister Tokiko remains subtextual rather than textual.
- Ambiguously Bi: It's less explicit than in the actually-pornographic installments of the franchise, but it's worth noting that Kotarou's relationships with both of the explicitly-male Taimanin characters that have been given focus (and one potentially male Taimanin) are just as fraught with sexual tension as the ladies. Of course, in all three cases, they still look pretty feminine, and Homare Nao seems to retain his hobby of dressing in women's clothing for fun. When Hebiko is drugged into a violently jealous frenzy during an event, it's not Kotarou's interactions with any of the female students that pushes her over the edge, but his "bromance" with Shikanosuke.
- Authority in Name Only: Kotaro is technically the heir and leader of the Fuuma clan, being Danjo's direct biological son and the legitimate offspring of him still living. But because of his young age, rather lazy nature, and because the clan was decimated by the Fuuma revolt, the day-to-day minutia of managing the few remaining clan holdings more often fall to Tokiko (who actually bosses him around as she's his older half-sister), and Amane and Saika handle the more complex and serious parts of the job (as the two retainers that have been serving the clan the longest).
- Badass Normal: For a given value of "normal", since he is still able to handle normal human Mooks relatively easily, but he has no Ninja Art. he knows this and has come to term with it, preferring to serve as Mission Control where he won't be a hindrance to his superhuman comrades.
- Berserk Button: Treating your friends as expendable pawns than individuals is a surefire way to make him go ballistic. Momochi ultimately earned his ire after witnessing his people transforming into demons with little to no concern for their humanity.
- Beware the Nice Ones: Kotaro is a decent and mild-mannered guy, but when push comes to shove, he is probably the last person you want to try piss him off.
- Blue Is Heroic: Kotaro has blue hair, and playable Saika's Intimacy Event shows he wears a blue Taimanin suit. Kotaro is also the compassionate and supportive leader of the Taimanin Task Force.
- Brilliant, but Lazy: It's repeatedly noted that he often gets bad grades even in classes where his lack of supernatural powers wouldn't be an issue. He claims that this is due to bad luck and the pressure of operating the Task Force on top of his normal schoolwork, but he does sometimes seem to be playing hooky to pick up new video games instead of training.
- Butt-Monkey: Despite being the POV character, Fuuma regularly ends up being humiliated, ridiculed, misunderstood, coerced, or forced to endure some other misfortune during or at the end of a story arc.
- Character Development: He comes to believe he owes it to the task force to put his life on the line like they do, and after sacrificing his command drone to distract an enemy he starts spending more battles on the front line with them. Learning that Toyo Momochi is also a Taimanin who despite his brains and skills couldn't ever awaken his Taimanin Art helps Kotaro reflect on how he himself has come to heal from his self-loathing on the subject over time.
- Composite Character: He's a combination of TABA Kotaro and Tatsuro Akiyama, Rinko's little brother from Taimanin Yukikaze as Yukikaze has more interactions with Kotaro, due to Tatsuro being Adapted Out, much less mentioned.
- Chick Magnet: Fuuma gets Ship Tease with plenty of the female Taimanin and even some of the villainesses. One of the gifts for raising a Taimanin's affinity that is guaranteed to be a level 3 gift is a Fuuma plush.
- Childhood Friends: With Kurenai Shinganji, which is an original element from Action Taimanin.
- Commonality Connection:
- Kotaro became friends with Mai Nanase and Shisui Amamiya over a shared interest in reading.
- In Spinel's Intimacy Event, Kotaro and the former find common ground over the fact they have nagging subordinates, Tokiko and Lapis, respectively, who act like their mothers while also giving them allowances.
- Determinator: His quality that finally wins over Su Jinglei is his unshakable determination, even in the face of failure and setbacks.
- Eyeless Face: The game makes sure to never show Fuuma's eyes whenever he appears onscreen even when the audience should see his one functioning eye. The only time we do see his eye is on the Fuuma Plush.
- Face of a Thug: Fuuma still has the same tan-skinned, creepily grinning character design as his original Battle Arena incarnation, even though that version of him was a Handsome Lech and sadistic rapist while this Fuuma is a stand-up guy who barely even qualifies for Chivalrous Pervert.
- Fighter, Mage, Thief: Unusually for a main character, Kotaro is firmly the "Thief" in his three person friend group of himself, Shikanosuke, and Hebiko. As the only one of the three with no Taimanin Art, he relies on his brilliant tactical mind, charisma, and technical skills to contribute, and if he's going to land a hit in a fight it's probably a cheap shot taking advantage of openings his friends help create.
- From Nobody to Nightmare: A heroic example. Fuuma's growth as an individual reminds the player that you don't have the need to learn your own ninjutsu to be a Taimanin, the more he grows a spine, the more he becomes a competent and effective leader. His strategic skills is enough to earn the respect of high-ranking demons like the King of the Death Wraiths and even Edwin Black himself, while being feared by all of demonkind at the same time.
- Guile Hero: Fuuma manages to talk Oboro into spilling useful information without torture by convincing her he actually intends to let her go if she does, all without actually promising anything of the kind.
- Irony: Kotaro Fuma often laments his inability to awaken his Taimanin Art, and the discrimination he's suffered from his own clan and other Taimanin in the process. But in the branch of the franchise that follows a timeline where he did successfully awaken his art, a mixture of its Power Parasite nature and being actively raised by his monstrous father molded him into a sadistic criminal kingpin and monstrous rapist rather than the mostly stand-up guy he is in Action.
- Last-Name Basis: No one refers to him as Kotaro, with the narration only doing so when other Fuumas are present. Especially notable considering that almost everyone else is on First-Name Basis with each other.
- Likes Older Women: As shown with his Inner Monologue in regards to Rin, Kotaro is also attracted to some of the older Taimanin.
- Mission Control: He follows the other Taimanin with his command drone, and radios the operatives in the field to share useful information mid-mission. He also handles hacking and navigation. After his drone gets blown-up during the disastrous second major expedition to Venam, he starts accompanying the Task Force in person, refusing to sit back and monitor his drones while sending them into danger.
- Muggle Born of Mages: He is one of the few unlucky Gosha inhabitants that are born without a Ninja Art. Some characters theorize that he could have one, but be an extremely late bloomers.
- Named After Somebody Famous: The semi-legendary Kotaro Fuuma
of the Edo period. - Nice Guy: Kotaro will gladly help anyone who needs it, and is at worst slightly rude to those who wronged him at some point, such as Felicia.
- Non-Action Guy: Kotaro isn't well-suited to straight-up fights, but he's very good at what he does. He does get into direct combat rarely, but whenever he does, it's usually to stall and buy time until stronger help can arrive.
- Not Quite the Right Thing: After defeating Edwin Black in chapter 19, Kotaro spares him, reasoning that the Evil Power Vacuum that would entail should Black die makes keeping him alive the better choice. As story events following that and the next story chapter show, the mere fact that Black was defeated at all has caused Nomad's reputation to plummet, multiple factions to break away from it, and Astaroth revealing Toyo's informations to the world caused extreme tensions within and between multiple world powers anyways.
- Rage Breaking Point: Momochi viewing his own followers as expendables by having them inject a Psycho Serum that turn them into mindless beasts to justify his endgame is enough to make Kotaro snap and Momochi earning his ire.
- Took A Level Inbadass: It's more subtle than other characters, but Kotaro's growing confidence as the story progress also comes with him becoming stronger as well, going from barely holding his own against even normal human Mooks to being able to fight multiple at once and even beat some of the lowest-ranked demons on his own.
- Screams Like a Little Girl: Can hit an impressively high note when faced with intimidating odds in the Intimacy Events, whether he's riding a motorcycle with Homura Sanada or chased by a boar.
- Situational Sociability: Kotaro is fully capable of having normal conversations with girls but if someone comes onto him, he quickly loses composure.
- Upbringing Makes the Hero: Unlike his Battle Arena incarnation, this Kotarou's inability to awaken his Taimanin Art meant that his father dismissed him as a possible heir from a young age and put little effort into actually raising him. That and the Fuuma Rebellion meant that Kotaro was mostly raised by his half-sister Tokiko instead, and this is why Battle Arena's Kotarou is an evil crime boss and a sadistic serial rapist while this Kotarou is a fundamentally good man and a respectable upcoming Taimanin.
- Warrior Therapist: Aside from commanding and fighting, Kotaro has also shown some psychological wit, being able to analyze and deconstruct Toyo Momochi's actions and motivations and snap Misaki Sengen out of her Chronic Hero Syndrome-induced anxiety while the latter is confined to the hospital and views herself as unable to perform any good deeds.
Asagi Igawa
Asagi Igawa
The Almighty
"I'm the head of the Taimanins, Igawa Asagi. Nice to meet you."
Voiced by: Ami Koshimizu (formerly)/Sayumi Watabe (currently)
Leader of all Taimanin, commonly known as the Almighty Taimanin. She utilizes physical capabilities and master swordsmanship, as well as her ability to move at the speed of light, to win battles. During her mission in Tokyo Kingdom, she awakened a demonic power within herself, further enhancing her ninjutsu.
She is the headmistress of the Gosha Academy, a government-founded educational institute for young Taimanin. Her weapon of choice is a ninja katana.
- The Ace: Asagi is Famed In-Story as an exemplar of what it is to be Taimanin: strong-willed, virtuous and wise, a mighty warrior, intelligent tactician, patient and capable teacher, and so much more.
- Badass Biker: In the Asagi: Bridge Race Special Mode, Asagi uses a motorcycle to collect coins and temporary upgrades while avoiding obstacles.
- Badass in a Nice Suit: Asagi can equip her headmistress outfit or her butler outfit in the field, and her Butler supporter wears a suit by default.
- The Call Knows Where You Live: She was actually planning to retire from her service as a Taimanin and get together with her civilian lover some years in the past. Cue Oboro abducting the guy and putting him, Asagi and Sakura through quite a few things we can't talk about in detail on this site (and that the game itself can't talk about without becoming another A-Rated game in the franchise, let's just say it wasn't pretty) until Asagi had to Mercy Kill him...
- Death from Above: Her Rakusenka has her hit her target with a downward slash by teleporting above her enemy. This is also carried over from her Hirenka, of which the final hit is from the Rakusenka.
- Deuteragonist: Asagi is the overall mascot character of the Taimanin series all while being the authority-in-figure of all Taimanins. In this game, Kotaro is the main character, thus making Asagi as this.
- Heartbroken Badass: Even after all those years, she still mourns the loss of her lover.
- Herd-Hitting Attack: Her basic attacks tend towards wide swings that can cleave into multiple targets at once.
- Jack of All Stats: Her playstyle is very well-rounded, and her skillset contains abilities useful in a variety of situations.
- Purple Is Powerful: Asagi, the "Almighty Taimanin", wears a purple Taimanin suit.
- Speed Blitz: Her Ninja Art lets her accelerate herself so fast she seems to be in six places at once. This is readily seen with her Ultimate, as well as her Koujinka Skill to a lesser extent which seems to make everyone but her move in slow motion.
- Simple, yet Awesome: It's worth noting that even after more than a decade of Power Creep, Asagi is still considered the strongest Taimanin in the setting, because even though her Speed Blitz isn't that complicated, it's endlessly strong and useful, and the woman using it is a master swordfighter with a brilliant mind who's good at everything else a Taimanin is supposed to be good at.
- Sugar-and-Ice Personality: On the job, she projects a no-nonsense attitude that shows why she commands a lot of respect among her peers and why she's feared by her enemies; when alone with those close to her, she shows her softer side.
- Time Master: Her Koujinka slows down time, allowing Asagi to move normally for a short second. But this requires her to time an enemy attack to activate the ability.
- Willfully Weak: An interaction between her and Shiranui all but states that, when on missions with Gosha agents, Asagi is purposefully holding back so she can see them in action and evaluate their skills.
- The Worf Effect: In Chapter 10, Asagi tries for a surprise attack on Astaroth and not only completely fails to hurt her, but is actually wounded and has her weapon melted in the attempt, to establish that The Queen of the Inferno is someone they should get away from as fast as possible.
Sakura Igawa
Sakura Igawa
The Young Taimanin
"Taimanin Sakura, at your service! Teehee!"
Voiced by: Haato Satoyama
Asagi's younger sister. Always bright and friendly. A young girl who gives off both a gorgeous and cheerful vibe.
Born with a rare ninja art just like her sister, she is a ninja who uses "Shadow Art". She became a Taimanin over her sister's objections, because she wanted to fight for justice like Asagi.
Sakura has helped her sister in multiple missions, and even if she isn't as well-known, she has made a name for herself as an exemplary Taimanin. She uses twin ninja daggers as her main weapon.
Believes she has a good relationship with Yatsu Murasaki, who actually despises Sakura, and only looks up to Asagi. She is often on missions with Murasaki when not with her sister. To other Taimanin, the duo are known as "Sakumura".
- Badass Adorable: A young, plucky Taimanin who kicks ass inside and outside of the battlefield.
- Beware the Silly Ones: She tends to be rather childish and goofy outside of battle, but she is still a force to be reckoned with.
- Casting a Shadow: Her Ninja Art lets her manipulate, shape, give solid mass to, and teleport between shadows.
- Dual Wielding: Sakura fights with two knives at once.
- Gamer Chick: It's shown in her intimacy scene that Sakura likes to play video games in her free time.
- Genki Girl: Sakura tends to be loud and energetic compared to her reserved sister, with a more childish side.
- Glass Cannon: Sakura's two-knife style is very, very good at taking a single target to pieces very quickly, but she has lower health and defense than her sister and she can't fight groups as easily.
- Oblivious to Hatred: Sakura thinks she has a good relationship with Murasaki but in truth, the latter can't stand her.
- Plucky Girl: No matter the hardships she and her comrades face as Taimanin, Sakura remains cheerful and somewhat childish.
- The Pollyanna: Sakura keeps Task Force's morale up, and has more connections to local businesses than her coworkers.
- Pop-Cultured Badass: This Taimanin loves video games, comics and anime.
- Retcon: Originally, Action was supposed to include both an older and younger Sakura, with the latter from another world, as is the case in RPGX, but most of the lines were cut or rewritten. The end result is that this is seemingly the only Sakura in existence, though much younger and with a bigger age, skill, and power gap between her and her sister than typically portrayed.
- Spin Attack: Sakura's Shadow Cleave attack has her revolve with her arms stretching out from the sides while she instantly teleports to the targeted enemy.
Yukikaze Mizuki
Yukikaze Mizuki
Lightning Bolt
"I'll show you the power of the lightning bolt!"
Voiced by: Yui Kanbe
Taimanin, student of Gosha Academy. Although still a student, she frequently takes on missions, and she is expected to be a leading force of the new generation of Taimanin. She often works with her senior Akiyama Rinko on missions, and is known as the Lightning Bolt for her Ninja Art, which allows her to create destructive bolts of electricity. She fights with paired pistols that channel and control her electrical powers.
She is almost perfect, except for her temper and pride. Very few know that she is quite shy with strangers.
- A-Cup Angst: Yukikaze is quite insecure about her small breast size and is easily angered when someone mocks her for it or compares her to the more voluptuous Taimanin, especially her mother and Rinko.
- Aren't You Going to Ravish Me?: Implied. When the team has to pass a checkpoint and the guards take advantage of it to grope Shiranui, Kotaro notes that Yukikaze doesn't seem angry as much as jealous that she wasn't manhandled as well.
- Berserk Button: The easiest way to upset Yukikaze is to insult her small breast size, which happens quite a lot.
- Blood Knight: She's one of the Taimanin who gets most excited about the prospect of fighting.
- Brutal Honesty: She doesn't handle Su with kid gloves, laying into her smug attitude and the fact that the Chinese Union, which Su is fiercely patriotic towards at first, is a brutal police state whose citizens are more afraid than proud.
- Guns Akimbo: Her weapons are a pair of flintlock pistol-esque Taima Shooters, modified to fire her tempered Ninja Art rather than ammo.
- Hot-Blooded: Yukikaze gets excited about fighting the enemy and is quite irritable when things go awry.
- Long-Range Fighter: Yukikaze is the only starting character to use ranged attacks as primary weapons. Enemies who get inside her reach give her a hard time, but she can throw down a lot of firepower to make sure they don't get there easily.
- Mage Marksman: A mix of the the "Gunman" and "Archer" types, as while she makes heavy use of her guns, they're conduits through which she channels her electricity powers rather than firing actual bullets.
- Power Limiter: Her gun's true purpose is to keep her immense power in check and to keep her aim precise instead of going overboard.
- Shock and Awe: Her Ninja Art lets her control and channel electricity at deadly voltages.
- Yellow Lightning, Blue Lightning: Nearly all her lightning abilities are colored in a yellow-ish green.
Rinko Akiyama
Rinko Akiyama
Savage Hunter
"Ittoryu acting master, Akiyama Rinko. Justice calls upon me."
Voiced by: Hana Satomi
Yukikaze's partner, Rinko Akiyama is another young Taimanin prodigy who still serves as a field agent. More cool-headed and reserved than her temperamental teammate, her Ninja Art, "Void" allows her to teleport herself and other objects within a certain radius and create space-time warps which suck enemies in. Rinko's favored weapon is the long-katana with sheathe, for quick-draw attacks.
- Adaptational Badass: Rinko's range with her Void Art is one kilometer in the game, but in Action she can teleport meteors from space with both her Ultimate and her Meteor Drop skill.
- Berserk Button: Similar to her partner, Yukikaze, making fun of her large chest is a quick way to make her angry.
- Childhood Friends: With Rinka Shido, and are together known as "the Double Rin of the Taimanin."
- Colony Drop: Two of her highest-damage moves involve pulling in high-velocity space debris to crush enemies.
- D-Cup Distress: Just as her best friend and Platonic Life Partner Yukikaze wishes she were curvy like Rinko, Rinko wishes she were small and cute like Yukikaze; in her Intimacy Event with Kotaro she repeatedly assumes he likes Yukikaze more than her when he's late to an arranged meeting.
- Difficult, but Awesome: Rinko doesn't have Sakura's single-target damage or the inherent advantages of being ranged like Yukikaze, and compared to Asagi her attacks are a bit slower and do less damage to health and Super Armor. However, she has powerful and useful skills when properly aligned (Meteor Drop in particular hits like the fist of an angry god with three blue Supports, and some of her moves can manipulate enemy positioning to a degree other playable characters cannot), and the final hit of her combo string creates a storm of slashes that hits every enemy in a huge radius in front of her for multiple attacks and high damage.
- Gravity Master: Rinko can also use the Void Art to create miniature singularities and draw enemies in.
- Iaijutsu Practitioner: She carries her longsword in a sheathe for quick-draw attacks, and many of her skills involve rapid slashes.
- Master Swordsman: Her father personally instructed Asagi in swordplay... and Rinko is considered nearly his equal.
- Purple Is Powerful: Like Asagi, Rinko wears a purple Taimanin suit, and is shown to be one of the stronger Taimanin in the game. Rinko also has purple eyes and hair to boot.
- Space Master: Rinko's Void Art lets her both teleport (her dodge animation is noticeably different from her peers' for this reason) and teleport others, willingly or unwillingly.
- The Tease: Shows a surprising side of this during her [Master] Intimacy Story towards Kotaro when he suggests going into a hot spring together, only for her to mischievously point out how intimate a proposition it sounded.
- Underboobs: She has a Cleavage Window on the lower side of her Taimanin Suit's chest area.
Murasaki Yatsu
Murasaki Yatsu
The Undying
"Taimanin Yatsu Murasaki. So, you're the captain, huh? Nice to meet you."
Voiced by: Nami Nakano
A teacher of Gosha Academy who is an active Taimanin along with her brother Kuro Yatsu, and is expected to take Asagi's place as the Taimanin captain of the next generation. She appears cold and stern on the surface but she is much kinder than she lets on. Murasaki practices the "Awakened Immortal" ninja art, allowing her to literally become immortal while having superhuman restoration abilities, and the only way to kill her is to destroy both the heart and the brain simultaneously. Murasaki's ninja art grants her increased power and agility, allowing her to swing her giant axe without much issue.
- Adaptational Badass: When using her ultimate, Murasaki sprouts several Combat Tentacles from her back, which she was only able to do in the visual novel after performing a Fusion Dance with Sabato Kiryuu.
- Contralto of Strength: Murasaki is one of the stronger Taimanin on par with Asagi and Shiranui as well as a stern teacher, befitting her one of the deepest female voices in the game.
- Drill Sergeant Nasty:
- Murasaki is a very kind and thoughtful woman but will inflict maximum disciplinary measures on anyone who underperforms or doesn't take their duties seriously.
- Even when Kotaro himself becomes a teacher to some academy students in an event, the reminder that Murasaki will supervise him too frightens him as much as it does the cadets.
- Healing Factor: And a fairly powerful one at that, as it is stated she can regenerate her entire body as long as her heart or brain are intact. It also comes with, and is very handily in training, Super-Strength.
- Kind Hearted Cat Lover: Murasaki's bio states she likes cats but the feeling is unmutual as they apparently fear her.
- Mighty Glacier: Murasaki's attacks have long wind-up times but high damage output, and her healing counter skill can make her one of the toughest characters in the game.
- Mundane Utility: It's suggested that her super-regeneration actually helps her work out her muscles without risking injury or over-training, helping explain why her Super-Strength is immense even among Taimanin.
- Super-Strength: She wields extremely heavy axes with relative ease and her Playable Intimacy scene shows her lifting 210 kg with more ease than Kotaro has to lift 30.
- Tomboyish Ponytail: Her hair is tied in a long, blue ponytail that flips wildly while swinging her axe.
- Weapon-Based Characterization: Her greataxe she uses in battle shows off both her discipline and well as her Super-Strength.
Su Jinglei
Su Jinglei
The Chinese Taimanin
"Su Jinglei, from the PLA. So you must be the captain?"
Voiced by: Marina Inoue
A soldier from the Chinese Union, sent as a liason with the Task Force during their first mission. Her great-grandfather was a Taimanin who married a Chinese woman and settled down, and she has some Taimanin heiritage. While she is familiar with Asagi, and respects her enormously, she is, initially, much colder to the rest of the Task Force. Becomes a playable character later down the line, using a pair of Power Fists for combat.
- Animal-Themed Superbeing: Su actually turns out to be a Beast Art user, although not a Beast Transformer. Her animal? Fittingly, given her origins, a dragon.
- Berserk Button: Calling her "cute" will earn you a Death Glare but if you insult her small cup-size, she'll give you a censored rant in retaliation.
- Defrosting Ice Queen: She slowly goes from a critic of all the other members of the Task Force (except Asagi anyway) to becoming a Taimanin like them and friends with them during the events of the first five chapters.
- Heel Realization: Originally a proud and patriotic servant of the Chinese Union, but after Yukikaze points out that the various nations China has vassalized chafe under its yoke, seeing first-hand the misrule in Venam, and being all-but threatened with death for her failure should she return, she decides to embrace her heritage and throw in her lot with the Taimanin instead; symbolically dressing like one of them instead of her Chinese army uniform. That said, an early event establishes she still has a decent enough relationship with her parents who support her choice, and they are not being persecuted because of her.
- McNinja: Su is a Chinese national who takes up the mantle of a ninja, though she is apparently one-quarter Japanese through a Taimanin great-grandparent.
- Not So Above It All: Su tries to position herself as the dignified, professional soldier to the squabbling Taimanin around her, but she regularly demonstrates that however she tries to present herself she's still just a normal teenage girl under it all. Even the serious and professional Su Jinglei struggles to keep a straight face while witnessing Lilim and Minasaki's laughably bad acting during one of the annual special camps, even though she insists she's not smirking.
- Pint-Sized Powerhouse: As short and petite as Yukikaze, but Su's incredible strength belies her small, slight stature. Many of her attack animations see her wrecking the ground with every punch.
- Power Gives You Wings: Invoking her Super Mode causes Su to channel her dragon power into energy wings, as well as sheathing her arms in energy blades. She then Power Floats for the duration of her Ultimate.
- Super Mode: Rather than a huge screen-clearing damage ability, her Ultimate instead grants her invincibility for its duration, making her immune to any damage or status effect and changing her basic attacks to be harder-hitting and striking a huge area for about ten seconds.
- Token Wholesome: Subverted. She starts out wearing a modest, frumpy People's Army uniform and beret, but at the end of the campaign she's switched to a typically-flattering Taimanin suit.
- Tsundere: After Chapter 5, she's seemingly picked up a crush on Fuuma, and expresses it by coming to his house to try to force him to be more diligent and hard-working in the morning.
- Wise Beyond Their Years: Played with. While Su is pretty knowledgeable with government affairs even for her age and appearance, her arrogance derails this during her first appearances in the Main Quest, thus finding herself in hot water because of the task force's failures. Luckily, she takes full responsibility by remaining with the task force and still remains knowledgeable with political and government affairs.
Shiranui Mizuki
Shiranui Mizuki
The Phantom
"Taimanin Shiranui. I'm still more powerful than Yukikaze."
Voiced by: Harumi Asai
Yukikaze's mother, and a powerful and well-respected Taimanin in her own right. Shiranui uses polearm weapons, and her Ninja Art can manipulate water.
- Action Mom: Shiranui is one of the more experienced Taimanin of the current generation and still better than her daughter, Yukikaze.
- Adaptational Badass: Notable because in the Yukikaze games she's been kidnapped and brainwashed twice, without getting to show her stuff except as a tool against her own daughter. She also preferred poisoned claws to polearms.
- Big Damn Heroes: Her entry in the story in chapter 10 comes when she drops in just in time to save the Task Force from Astaroth. Unusually for this trope, she's clearly not strong enough to defeat the demon, but helps turn the fight into a less one-sided stomp and buy the team enough time to get to safety.
- The Creon: Shiranui's presence is a major point of divergence from most other timelines in the Taimanin franchise, since she's able to serve as Asagi's loyal and extremely capable right-hand woman, and to lend her considerable power and organizational skills to situations that would go very badly without her. She also frees up Murasaki from having to assume the role, in which she would be competent but not great, allowing her to instead focus on the teaching and instruction jobs Murasaki is genuinely great at.
- Elemental Shapeshifter: She can physically transform her body into water to avoid attacks.
- Feminine Mother, Tomboyish Daughter: She has a relaxed and flirtatious temperament compared to her hot-blooded and impetuous daughter.
- Like Father, Unlike Son: While she and her daughter share some obvious physical traits, such as hair and eye color, they are very different in temperament, figure, haircut, fighting style, elemental powers, and everything else. Notably, despite being such strong visual and characterization foils, they seem to have a decent relationship.
- Making a Splash: She can hurl water as projectiles with great force, use it to slide around the battlefield with her mobility skills, or add cutting power and pressure to her attacks.
- Naginatas Are Feminine: It's probably not a coincidence that the most traditionally-Japanese woman on the task force is also the one wielding a polearm.
- Shipper on Deck: In the Intimacy Event for her New Year's Eve Supporter version, she expresses approval of the idea of her daughter, Yukikaze, getting together with Kotaro.
- Team Mom: Out of all the playable Taimanin, she's the only one who's been explicitly mentioned to have domestic skills, probably because she's the only one to balance her career with being a homemaker at some point.
- Throw the Dog a Bone: In every other iteration of the franchise, Shiranui is a deeply tragic figure, used as a brainwashed Sex Slave by various demonic monsters until she's willing and able to do unspeakable things to her own daughter. Here, having avoided that fate, Shiranui is living a fairly happy life and serving as one of the most powerful and capable Taimanin in the world, while being able to raise her own daughter as a mother.

A UFS scientist who the task force encountered during a mission at Kotrara Island. Emily believes science and technology are mankind's greatest achievements and has shown interest in the Taimanin's superhuman skills, hoping to find a way to make them available to everyone.
Emily uses a combat exoskeleton in battle that allows her to fight the enemy with high-tech weapons.
- Badass Adorable: She's a perky Science Hero with a heart of gold who uses her technology to help those in need.
- Badass Normal: Explicitly not supernaturally empowered like most Taimanin, she gets on by with her exoskeleton and flying turret drone.
- Canon Foreigner: Never having appeared in the main series, this is Emily's first appearance in the Taimanin franchise.
- Cyborg: It's not as obvious or extensive as the other Machine-type characters, but Emily's body does incorporate some cybernetic implants to interface with her gear and channel Taima particles. It's also one of her explicit specializations; she studies the Taimanin's superhuman bodies hoping to gain scientific knowledge to advance the field of prosthetics.
- Death of a Thousand Cuts: She does not deal a lot of damage per attack, but nobody attacks faster than her due to her fighting with a flying turret that keeps shooting as long as you hold the button or have the Zero System installed.
- Flag Bikini: One of her outfits includes the Stars And Stripes in the sort of way you could expect from this game.
- Geeky Turn-On: While it's not as explicit as Murasaki's outright crush on Asagi, Emily does sometimes get a bit too into the idea of studying Taimanin's bodies, especially Asagi's. While she's in it to satisfy her intellectual lust For Science! rather than sexual lust, onlookers do find it a bit perverted and creepy, and it's suggested that Emily gets an almost-sexual fulfillment out of pursuing scientific inquiry.
- Hair of Gold, Heart of Gold: Emily is blonde and is one of the nicest characters in the game.
- Photographic Memory: She's mentioned to have perfect recall as part of her characterization as a brainy scientist.
- Powers Do the Fighting: Gameplay-wise, it is entirely possible for her to complete missions without the player touching anything since one of her skills let her turret shoots enemies without player imput and it also automatically moves her alongside the mission path. Story-wise, she is explicitly operating her drones.
- Science Hero: Believing that science is humanity's most important asset, Emily wishes to study the Taimanin to research a way to make their superhuman attributes available to everyone in need while using her technical and scientific prowess to assist the task force.
- Shipper on Deck: In the Intimacy Event for [Master] Akiyama Rinko, Emily thinks Rinko and Fuuma look cute together while enjoying the secret hot spring together. Yukikaze disagrees.
- Smart People Wear Glasses: Emily wears glasses, and is one of the smartest characters in the game, possessing a photographic memory that allows her to remember everything she witnesses and is a capable multitasker who has extensive scientific and technological knowledge.
Kurenai Shinganji
Kurenai Shinganji
Crimson Maiden
"Taimanin Shinganji Kurenai, reporting for duty! Who would have thought I'd join the task force?"
Voiced by: Nanae Sakurai
Kurenai is half human and half vampire yet lives as a Taimanin, which is considered heretical among them. She was once considered the heir of the Fuuma clan and was taught swordsmanship by her grandfather, Gen-an, but this fell apart due to Fuuma Danjo's revolt. Kurenai left Fuuma's village to go solo but still helps Fuuma Kotaro due to being childhood friends.
Kurenai has mastered the Shinganji dual wield style and wields a dual pair of swords named "Shirakami" and "Koma" whom she inherited from her grandfather, which together with her ninja art "Wind Art" allows her to create a whirlwind zone.
- Adaptation Relationship Overhaul: In this timeline, Kurenai and Kotaro are childhood friends, and it's unclear and ambiguous if Edwin Black is still her father or Felicia her sister. And whether or not her best friend Ayame is outright in love with her or just an extremely close Pseudo-Romantic Friendship is more ambiguous than in her solo title, where Ayame was indeed romantically attracted to Kurenai and Kurenai eventually reciprocated.
- Ambiguously Related: Only ambiguous by virtue of not being mentionned at all. It's left unsaid if she is still the Child by Rape of Edwin Black or not in Action as she is in other parts of the franchise (which would explain her burning hatred of Black and her vampiric powers), which also makes her relationship towards Felicia (Black's daughter in all iterations of the franchise and Kurenai's half-sister in other canons) ambiguous.
- Badass Longcoat: Wears a blue/white longcoat over her Taimanin suit, which enforces her badassery.
- Blow You Away: Kurenai uses the Wind Art, which allows her to create gusts and tornados during combat.
- Childhood Friends: With Kotaro Fuuma, which is an original element from Action Taimanin.
- Cleavage Window: Her default outfit gives a good look at her breasts.
- Foil: To Asuka. Both are Half-Human Hybrid Taimanins (Kurenai is half-vampire, whereas Asuka is a Cyborg thanks to her prosthetic limbs) who have a personal beef with Edwin Black, who is also responsible for the deaths of their loved ones.
- Friend to All Children: She likes kids and enjoys working at the Himawari orphanage. Kurenai's Intimacy Event shows her reading a book to the children of Himawari.
- Girlish Pigtails: She typically wears pigtails in her outfits.
- Half-Human Hybrid: She's half human, half vampire.
- Human Mom, Non-Human Dad: Her mother is human whereas her father is a vampire.
- I Work Alone: After Fuuma Danjo's failed revolt, Kurenai decided to disassociate herself from any other clan and go solo. In the end, she decides to join the task force after bumping into them at Tokyo Kingdom.
- It's Personal: She hates Edwin Black for killing her mother, and jumps at any chance to return the favor.
- Pointy Ears: From her vampire heritage.
- Single Woman Seeks Good Man: Kurenai is implied to be in love with Kotaro and remarks on his kindness in her playable version's Intimacy Event.
- Tornado Move: She's got a lot of them:
- "Spiral Rend" uses a small tornado to launch the enemy into the air, before she jumps up to attack them before they fall down.
- Her "Tornado Rend" move creates a small tornado that will damage enemies in its path. Depending on what additional effects are applied, it can either knock enemies in the air, stun them, or not move to damage the specific area where it's cast.
- Her "Storm Zone" creates a smaller one, affecting a single enemy and knocking them up.
- "Storm Fang" targets a single enemy and creates a huge tornado to heavily damage them.
- Her ultimate attack, "Whirlwind Zone", inflicts extremely high damage on all enemies on-screen.
- True Blue Femininity: Kurenai's default outfit is colored blue and she doesn't show a lot of masculine traits.
- Wind Is Green: All her wind attacks are green-tinted.
- You Killed My Mother: Edwin Black, the leader of Nomad and a prominent enemy of the Taimanin, killed her mother, and Kurenai won't rest until she has avenged her.
Asuka Koukawa
Asuka Koukawa
Steel Reaper
"Koukawa Asuka, reporting in! Fufu, was it really necessary, between you and me? ♪"
Voiced by: Juri Nagatsuma
Asuka is the young head of the Koukawa clan that was destroyed by Edwin Black, leaving her as the only survivor. She was subsequently raised by Asagi and gained notoriety as a Taimanin at age 14 due to her high performance on dangerous missions. During a fateful encounter with Edwin Black, she ignored Asagi's orders to stay put and instead challenged the Vampire King, costing her her limbs, and she disappeared afterwards. Asuka would eventually reemerge with cybernetic replacements and sow fear among her adversaries as the "Steel Reaper."
Asuka Koukawa fights with a pair of wrist blades that she uses with her mechanical limbs to create a formidable fighting style.
- Adaptational Intelligence: In Taimanin Asagi 3, while Asuka wasn't exactly stupid, she tended towards blunt, brute-force attempts to solving her problems, often being wasteful with her high-tech weaponry, and needed to go through Character Development as part of her story in order to emerge victorious. This Asuka not only seems to have finished all her personal growth but has taken on a command role within the UFS, although she still sometimes has her moments of childishness.
- Arm Cannon: She shoots missiles from her wrist in her "Kill-Em-All missiles" attack.
- Artificial Limbs: After a failed attack on the hated Edwin Black, her arms and legs were left in seriously damaged condition and she had to replace them with cybernetics. They not only store blades on her arms and legs, but a variety of other armaments like missiles and a Wave-Motion Gun.
- Blade Below the Shoulder: Asuka primarily fights with blades attached to her wrists that emerge from her cybernetics.
- Cyborg: She lost her arms and legs after foolishly challenging the Vampire King, Edwin Black, but they were replaced with cybernetic replacements.
- Dressed Like a Dominatrix: During "Taimanin VS Mistress of Darkness(?)", Asuka dresses up as the skimpily dressed villain, "Mistress of Darkness", as part of an undercover mission, and is quite embarrassed about being forced to wear it at first, although by the end of the mission she's really gotten into character.
- Foil: To Kurenai Shinganji. Both are Half-Human Hybrid Taimanins (Asuka has prosthetic limbs, making her a Cyborg whereas Kurenai is a half-vampire) that also have a personal vendetta against Edwin Black, who is responsible for the deaths of their loved ones.
- Girly Girl: Asuka has incredibly long hair, wears pink and has girly mannerisms, making her one of the girliest Taimanin, although she has her tomboyish streaks like getting really, really into baseball.
- It's Personal: She hates Edwin Black for annihilating the Koukawa clan and her family with it, and seeks to destroy him.
- Kick Chick: Asuka integrates kicks into her fighting style, and her cybernetic legs sport retractable heel-blades.
- Long Hair Is Feminine: Asuka has hair that reaches all the way to her thighs and is one of the girliest characters in the game.
- Motherly Scientist: She has a very good relationship with Kenji Kotani, the kind, fatherly Japanese expat UFS scientist who invented and works on her cybernetics. Her Supporter version's intimacy event is getting him to take her out to a baseball game after she finds out he took his wife and kids to an amusement park.
- Not Quite Flight: Her Wind Art lets her swoop and glide around, and her basic combo chain involves impossible spinning kicks utilizing it for extra hang-time.
- Pink Means Feminine: She wears a pink Taimanin suit with mechanical limbs to boot and has a very girly personality.
- Razor Wind: Her basic combo chain, when upgraded, has every move of her produce blades of wind, giving her a very slight measure of ranged attacks.
- Sole Survivor: Asuka is the only still living member of the Koukawa clan after Edwin Black wiped it out.
- You Killed My Father: Her family was killed when Edwin Black of Nomad destroyed the Koukawa clan, and her hatred for him hasn't withered since.
- Wave-Motion Gun: Her ultimate, Ultra Particle Cannon, has her flying into the air and unleashing a charged beam cannon upon the battlefield.
Kirara Onisaki
Kirara Onisaki
Hybrid Taimanin
"I'll help you on your missions 𝅘𝅥𝅮. Leave it to me, Onisaki Kirara!"
Voiced by: Satomi Akesaka
A half-Taimanin, half-Oni who inherited her ninja art from her Taimanin father and ice powers from her Oni mother who was known as the "Frost Phantom." Kirara uses her ice powers in battle to freeze moisture to create ice shields or to freeze her opponents but an argument she once had with her father made her decide to refuse to use her ninja art, with few knowing what kind of ninja art she uses.
- Cute Monster Girl: She's a half-Oni with an easygoing disposition (when her temper isn't up) that has the appearance of an adorable young woman.
- Does Not Like Men: Kirara hates men so much that she compares them to animala, though her interactions with Kotarou makes her at least changes her views on him, even developing feeling for him.
- Elemental Rock-Paper-Scissors: She attempts to use her ice powers to counteract Astaroth's superheated flames and body at one point, and fails because the demon queen's fire is simply too hot.
- Freakiness Shame: She developed a complex over the Oni-characteristic horns growing out of the sides of her head ever since she was a child and hides them with ribbons and pigtails.
- Girlish Pigtails: She wears shaggy pigtails in order to conceal the horns on the side of her head that she inherited from her mother, something that she is ashamed of.
- Harmless Freezing: Zigzagged. While sometimes those frozen solid by her ice powers can be easily thawed out harmlessly later, sometimes it's treated as the lethal ordeal it would realistically be, something only demons and superhumans could survive.
- An Ice Person: Kirara uses her ice powers inherited from her mother to fight demons and humans alike.
- Meaningful Name: A half-oni girl whose last name is Onisaki.
- True Blue Femininity: She wears blue clothes and is not afraid of showing off her feminine features.
- Tsundere: Kirara can be quite bashful as seen in her animations but tries to hide it with attitude. Some characters can see through her act anyway.
Noah Brown
Noah Brown
Rogue Demon
"Noah Brown. ———Pleased to, meet you?"
Voiced by: Aoi Koga
Noah Brown is a demonic chimera who Edwin Black created by merging multiple demon cells, leading her to carry multiple demonic traits such as her immortality, which is on par with that of higher-ranked demons, leaving her with a lack of fear and a will to fight. Despite having the appearance of a young girl, she is actually decades old. She was programmed to be a cannibalistic demon but she refuses to eat humans because she doesn't like the taste, instead preferring to eat sweets, which quickly leaves her fatigued. Though she initially served Astaroth due to the latter making a deal with Edwin Black, she fell in love with Fuuma Tokiko's food and has stuck with the Taimanin Task Force ever since. Noah shapeshifts parts of her body to use as weapons in combat.
- Badass Adorable: Noah can kick plenty of ass despite looking like a harmless little girl, especially when she has optimal fatigue.
- Big Eater: Noah eats gigantic meals and originally joined the task force in exchange for Tokiko's cooking. It's later justified; her body is optimized for eating humans but Noah refuses to do so, and every other form of nourishment is extremely inefficient for her.
- Cast from Calories: All her abilities are this, using any of them quickly tires her out and she needs to regularly eats. At one point, Kotaro powers her up by feeding her a bit of his blood.
- Cute Monster Girl: Noah is a demon with the appearance of a young girl that's actually much older and more powerful than she looks.
- Dark and Troubled Past: Originally created as a bioweapon, Noah's Nomad designers considered her a failure due to her unwillingness to live up to her full potential by cannibalizing other sapient creatures for decades. Nomad managed to temporarily break her will by tricking her into killing the researchers who treated her like a friend and child rather than a test subject, leading to her being a reluctant minion of the organization at the start of the story.
- Dark Is Not Evil: Despite being a demon wearing dark, edgy clothes, she's very kind, considerate and loyal to her friends, and her comparative weakness is part of a refusal to consume human beings.
- Emotionless Girl: Her refusal to eat humans leaves her fatigued, making her unable to show much emotion. She can show stronger emotion once she's well-fed, however, and it's made clear that being tired doesn't always mean she doesn't feel emotions.
- Healing Factor: Due to being made from powerful demons, Noah possesses an extremely potent one, easily rivaling that of greater demons (even if not matching to the Royal ones' like astaroth or Edwin black). In gameplay, she has several abilities that can be built to give her great sustain.
- Humanoid Abomination: Despite her humane appearance, Noah is actually an artificial being made from fragments of powerful deamons (among which is Edwin Black himself).
- Horror Hunger: She is near-perpetually hungry, as using her abilities tire her out very quickly and refusing to eat human beings has left her perpetually hungry and under-nourished.
- Meaningful Name: Noah Brown was created from a chimerization of many demons' cells, but most prominently Edwin Black, who is implied to have wanted an heir and to have disowned her, at least partially, when she did not live up to her full potential in his eyes. Astaroth has compared her becoming the full-powered demon she was intended to be as her becoming "black" instead of remaining "brown."
- Nice Girl: Noah is shown to be considerate of her teammates and comforts them whenever they seem troubled. It's heavily implied that she doesn't actually find the taste of humans unpleasant, but that she has enough moral awareness to believe that eating them would be wrong.
- Older Than They Look: Noah looks like a young girl but is actually decades old.
- Rei Ayanami Expy: She is a child-like demon and an artificial spawn created on Edwin Black's behest who often rarely expresses her emotions and is fond of eating human food over humans who ends up on the side of the good guys.
- Sizeshifter: Her Ultimate ability involves growing to gigantic proportions, and many of her attacks see her growing individual limbs for blows.
- Strange-Syntax Speaker: As shown by her quote above, due to being a pepetually-tired Artificial Human, Noah speaks strangely, using pauses between words that shouldn't have them, or even in the middle of words.
- Super Mode:
- Gameplay-wise, her Ultimate involves her growing in size to be bigger than the bosses, changing her basic attacks to wider-hitting and more damaging ones, and making her completely invulnerable, for its duration.
- There's also special art for when she embraces her full potential and takes on an even-more demonic form called "Chaotic Void" in an event, complete with a skin and Supporter version of her in that shape.
- Tastes Like Friendship: Originally an enemy of the Task Force, a chance meeting in Tokyo Kingdom leads to her being offered food by the Task Force, and thence to her defection once she realizes she has somewhere to go that's probably going to treat her better than Nomad.
- Terse Talker: She speaks in concise speech patterns because talking leaves her tired so she shortens her speech to preserve fatigue. Once she's well-fed she's fully capable of speaking in full sentences.
- Too Spicy for Yog-Sothoth: The Christmas 2023 event sees Wight, a shapeshifter, attempt to mimick Noah. She takes her appearance... and completely freaks out when she feels Edwin Black's power within Noah, changing shapeshifting targets in seconds.
- Unskilled, but Strong: Due to her tremendous strength and potential, Noah has never been actually trained in using her powers effectively. This is explicitly commented on by Kotaro in one of the event, where he has to fight Noah, he notes that while he is nowhere near strong enough to actually damage her or even meaningfully fight back, her strikes are clumsy enough he can still dodge them waiting for his allies to help.

Butler of Fuuma
"Fuuma Tokiko, here to serve my master."
Voiced by: Ayaka Shimizu
A teacher at Gosha Academy and the Fuuma clan's personal butler, Tokiko was born out of wedlock after an encounter between Danjo and his mistress, making her Kotaro's half-sister. She's supportive of Kotaro and did everything she could to make her half-brother succeed as clan master and save the clan from collapsing after the conflict with the Igawa clan, becoming his guardian at 11 years old. She uses the Fuuma characteristic "Evil Eye" ninja art, with her "Clairvoyance" variant allowing her to spy on anyone or anywhere without having to physically move simply by closing her eye, allowing her to gather information from books and computers with ease. Tokiko's favored weapon is the kunai, being the best among the Fuuma clan at using the weapon.

- Nice Girl: She's quite polite and understanding to the people around her, and even when she's hard on her half-brother he and the audience know it's Tough Love.
- Supreme Chef: She's noted to be a good cook who won over Noah Brown with her food, convincing the demon to join the task force.

Voiced by: Megumi Toyoguchi
Like an old-fashioned delinquent, Maika frequently helps the weak and fights the strong. In spite of her foul-mouthed demeanor and wild image, she's secretly fond of gyaru fashion, only wearing her best clothes where no one will recognize her, and is rumored to have a secret stash of adorable girly things. Even among users of the ninja art, Fire Art, which is known for its immense power, Maika's power is incredible, forcing her to equip a handmade bazooka named "Meido Bazooka," lest she loses control of her powers.

Rin Uehara
Rin Uehara
Volt Taimanin
"Uehara Rin. From now on I'll be joining you as a task force member."
Voiced by: Yukako Kiuchi
Rin Uehara is a substitute teacher at Gosha Academy when she's not on missions, and trains them for real battles. She considers every student under her watch Taimanin even if they are rookies and pushes them to their limits. Rin uses Volt Art, her power being greater than Yukikaze's, and looks like she glows with electricity while using it, earning the nickname, "Volt Taimanin." She can use her ninja art to conjure lightning blades or electron shields. Rin is often assigned to raid and annihilation missions, and thanks to her high rate of success, has gained the trust of the higher-ups, including Asagi. She's Shikanosuke's cousin.
- Adaptational Modesty: Her thighs are covered and her Cleavage Window has been removed, though her Playboy Bunny outfit looks similar to her original Taimanin suit.
- Combat Tentacles: All of her outfits incorporate two mechanical bladed tendrils she wears attached to a collar on her neck, and which she uses in both her moveset and several of her skill attacks.
- Dual Wielding: Rin wields a pair of dual swords into combat, usually charged up with her Volt art.
- Elemental Shapeshifter: Not as emphasized as Shiranui, but she can transform into lightning to zip around and uses it in her Ultimate attack.
- Evil Knock Off: One of her costumes, a suit of formfitting Cyberpunk armor, is actually a Battle Trophy she took off what's heavily implied to be an evil clone of her that Momochi Toyo's body double purchased along with other evil clones from a Mad Scientist in a previous event.
- Red Baron: "Volt Taimanin," from the way her body glows while using her ninja art.
- Shock and Awe: Rin's Lightning Art is said to outshine Yukikaze's. She incorporates it in her entire moveset, and it fries villainous attempts to put her in a mechanical Slave Collar.

Sora Kannazuki
Sora Kannazuki
Celestial Fox
"I'm Kannazuki Sora. Though I have much to learn, I'll do my best-!"
Voiced by: Saya Aizawa
A middle-schooler at Gosha Academy, she was rescued from the Chaos Arena and brought to Gosha after a demon who had a grudge against Sora's mother killed her and her husband. She was acknowledged for awakening her ninja art and defeating a demon who intruded and attacked Gosha, and was dispatched to the UFS. Sora's Visage Art allows her to summon visions of a fox or a giant. Her fighting style consists of adding particles to the arrows on her weapons, and after her ability to control particles was increased, she gains a fox tail and ears when using her powers, similar to Beast Art users. She initially used a wrist-mounted crossbow in battle but later switched to a longbow.
- Break the Cutie: Sora was traumatized by the murder of her parents and comes across as shy and timid in the present. Awakening her Taimanin Art was also under very stressful circumstances, and its been foreshadowed that Sakuya's growing envy of her won't be any gentler...
- Bully and Wimp Pairing: Sora is friend with Sakuya Igawa, with the younger Igawa as the cold, harsh, blunt and sometimes mean-spirited bully, and Sora as the Shrinking Violet Nice Girl who never dares raise her voice and lacks assertivness.
- Discard and Draw: Awakening her Taimanin Art allows her to summon a fox-masked spirit to help her fight, but caused her to switch out her weapons to better match the spirit's longbow.
- Long-Range Fighter: Sora uses a bow as a playable character and a wrist-mounted crossbow during cutscenes as a supporter.
- Mage Marksman: Fully in the "Archer" type. Like Yukikaze, Sora's bow isn't so much a weapon in its own right as it is a way for her to channel her Ninja Art in a focused manner, firing magical projectiles.
- Nice Girl: Quite so to her friends. In her Intimacy Story, she took Kotaro on an outing specifically to get him a break from his heavy workload, assuring he's well-liked amongst the task force, and insisting on doing things he want.
- Rain of Arrows: Sora actually has multiple skills that summon showers of projectiles to pummel enemies in front of her.
- Recoil Boost: Some scene transitions see her use her bow this way to launch herself to a higher level.
- Ship Tease: Her Intimacy Story frames the outing between herself and Kotaro it as a date, especially when the former gets flustered when the latter says he wants to know everything about her; that was the moment she understood why Su and Yukikaze scold Kotaro a lot. At the end of the story, her classmates tease her about it having been asked about date spots while a sighing Sora keeps denying it being one.
- Summon Magic: Her Ninja Art summons a ghostly fox-masked spirit who can fire off all sorts of powerful attacks, and even physically lift her in some stage transitions.
- Those Two Guys: Sora and her close friend Igawa Sakuya were introduced together training under Asuka in the UFS. However, Sora starting to awaken to her full potential has started to cause Sakuya to give in to envy, which is both slowly driving a wedge between them and may be putting Sakuya on a dark path...
- Took a Level in Badass: Gameplay-wise, she went from a Supporter to a playable character. Story-wise, she went from a student that couldn't awaken her Ninja art to one that had, and a fairly powerful one at that.
- Traumatic Superpower Awakening: She and Sakuya had gone to train in the forest when they were attacked by a powerful demon. After failing to run away and seeing Sakuya beaten unconscious and the demon about to kill her as well, Sora's Ninja art awakened and she disintegrated the demon with an energy blast.
- You Kill It, You Bought It: Downplayed, but the demon Sora killed during her Traumatic Superpower Awakening turned out to be the ex-leader of a group of demonic mercenaries, meaning that, in chapter 20 of the story mode, the newly-appointed leader of that mercenary group, Spinel, is specifically trying to kill Sora to earn the respect of her new underlings.

- Extreme Doormat: Nagi's devotion to trying to atone for her family's misdeeds manifests as slavish obedience to anything Kotaro tells her to do. Notably, when her deepest desire is shown in a dream, it's just her being given an endless stream of easy-to-follow orders from Kotaro that she can happily obey forever.
- Heel–Face Turn: While initially loyal to her father's faction, Nagi switched sides after witnessing the lengths her father was willing to go to achieve his goals and how much he was destroying himself.
Saika Fuuma
Saika Fuuma
Former Secretary of Fuuma
"Allow me to be the vanguard, young master. Fuuma Saika, at your service."
Voiced by: Yuina Wada
Saika hails from a family that has traditionally served as the Fuuma clan's secretary. She eventually passed down the role of secretary to Tokiko, and goes out on missions as a Taimanin.
She used to be an active Taimanin before she lost both of her legs in combat against demons. The former clan head and Kotaro's father, Danjo, saved her life on the brink of death, and the two went to UFS where she was given mechanical prosthetics. In spite of this, Saika sided with Asagi rather than her old master during the Fuuma revolt.
She utilizes her cyborg legs in combat to deliver powerful kicks, and her Evil Eye allows her to take control of anyone who meets her gaze.
Due to complications regarding the Fuuma Clan, Saika isn't an official member of the Task Force and acts instead as a supplementary agent who's given permission to tag along on missions in emergency situations.
- Artificial Limbs: Saika lost both of her legs during combat against demons but got mechanical replacements from UFS, which she uses in combat.
- Badass in a Nice Suit: She can equip Amane Fuuma's butler outfit.
- Combat Stilettos: Saika's mechanical legs have built-in high heels, which seem to conceal some kind of weapon. Fortunately, she has superhuman balance, as she demonstrates with many of her skills and her victory pose.
- Cyborg: Her ruined legs have been replaced with high-powered combat prosthetics, which is why her fighting style involves lots of kicking.
- Kick Chick: Primarily uses kicks in battle, with her cybernetic legs considered as her weapons.
- Mrs. Robinson: Saika is in her thirties, about the same age as Asagi and Shiranui, and confesses to Kotaro, who is in his late teens or early twenties, that she's in love with him in her playable version's Intimacy Event.
- Nice Girl: Saika is known for her warm and polite demeanor, which Kotaro especially notes in her friendly smile.
- Sexy Secretary: She used to be the secretary of the Fuuma Clan when Danjo Fuuma was still around but she passed the torch to his daughter and Kotaro's half-sister, Tokiko. Like the rest of the female Taimanin, Saika is also a very attractive woman.
- Sultry Bangs: Saika has her left eye always covered by her long tresses, giving her a sultry appearance.
Shisui Amamiya
Shisui Amamiya
Mysterious Girl
"Long time no see...... Or is it? Nice to meet you, Clan Master."
Voiced by: Aoi Koga
A mysterious girl who is often seen at the library. Shisui uses the rare Wave Art to materialize natural aura into a visage of the "Guardian" that she can manipulate at will.
- Bookworm: Excitedly discusses books with Fuuma at the Gosha library.
- Emotionless Girl: Speaks in a monotone voice with no audible emotions.
- Innocent Means Naïve: Shisui foolishly takes advice from Lilim, a well-known prankster, about what part-time job she should apply for. Turns out the job was as a receptionist in a bunny suit, and Shisui doesn't see why Kotaro freaks out when he witnesses her dressed in the outfit.
- Non-Linear Character: She appears to be aware that Action is an Alternate Universe, as Kotaro notes that when he met her for the first time, she told him that it was "nice to meet him for the first time again".
- Robot Buddy: Shisui can use her Wave Art to materialize natural aura in order to summon a visage of the "Guardian."
Hebiko Aishu
Hebiko Aishu
Low-Rank Childhood Ninja Friend
- "Fuuma-chan, you can always count on me, Aishu Hebiko, from now on!"Voiced by: Mai Fuchigami
Aishu is an elite Gosha student and a member of the student council. Her family has served the Fuuma clan for generations. Her Ninja Art "Beast Transformer" allows her to transform her legs into octopus tendrils.
- Adaptational Wimp: Marginal, but in both story scenes and gameplay Hebiko's healing game is pretty weak and dependent on drenching herself in her ink first. In RPG, she could flat-out regenerate and even regrow her transformed octopus legs in short order.
- Animorphism: The "partial transformation" variety. Her Beast Transformer art turns her legs into octopus tendrils and lets her spray ink.
- Dual Wielding: She wields a pair of daggers, sharing a weapon class with Igawa Sakura. She's said to be able to quadruple wield by using her hands and leg-tendrils to hold daggers, and unlike in other games in the series where this is just a distraction tactic, she actually uses them. (In story anyway.)
- Fighter, Mage, Thief: Firmly the "Fighter" in her friend group with Kotaro and Shikanosuke. She's the only one of the three that's a major physical threat in hand-to-hand combat, with her super-strong tentacle legs and swords. When the trio operate as a unit in events she's usually the one that ends up doing the lion's share of the fighting, taking on even gauntlets of reasonably powerful opponents despite still being a rookie high schooler. While she does have some skills in stealth and tracking using her ink, Hebiko is also usually more of a doer than a planner and relies on Kotaro's tactical genius and Shikanosuke's electric radar to point her in the right direction.
- Heart Is an Awesome Power: Being able to turn her legs into octopus tentacles and spray ink doesn't sound as impressive as most other Taimanin Arts... but it'll fool ya. In practice, Hebiko's shapeshifted legs are two slabs of pure muscle with ridiculous reach and flexibility thanks to being both boneless and scaled up to her human size. And since she's a ninja, she can do a ridiculous number of things with her ink, from using it to mark targets to coating herself in it to temporarily become invisible and gain octopus-like regeneration, to creating ink constructs as distractions or weapons.
- Height Angst: Claims to be 150 cm tall, and gets pissed when someone points out she's only 149 cm.
- Non-Indicative Name: Her family name of Hebiko (Snake Woman) comes from her great-grandmother, whose use of Beast Transformer allowed her to become a serpent. Hebiko herself instead has an octopus Beast Art.
- Pint-Sized Powerhouse: Hebiko is so short and small that Sakura's knife weapons are as big as shortswords in her hands, but between the two she's actually the stronger, especially with her transformed octopus legs in the mix.
- Turns Red: When fought as a boss in story events, lowering her health past certain thresholds will cause her to gain an armour buff that increases the lower her health gets, to the point that taking the last tenth of her life will take as long as it did to remove the first half of her health bar.
- Weaponized Stench: Her ink is infamously foul-smelling and fishy and takes days to clean out or fade away; it's implied that this is why just spraying it in a column with one of her attack skills is enough to knock enemies out.
