     Tatsuya & Miyuki Shiba 

Tatsuya Shiba
Voiced by: Yuuichi Nakamura
Course: 2 (Volume 1~11), Magical Engineer Course (Volume 12~)
Year: 1st (Volume 1~11), 2nd (Volume 12~)
Class: E
The male protagonist and the elder brother of Miyuki. He is a Guardian/servant of the Yotsuba clan, one of the 10 Families. He is also the Special Lieutenant of the 101st Independent Magic-Equipped Battalion.

  • Affectionate Gesture to the Head: His default method to soothe Miyuki.
  • A Lady on Each Arm: Courtesy of Miyuki and Honoka.
  • Almighty Janitor: He constantly outperforms Course 1 students despite being a Course 2 student, due to poor results in practical testing. However, it turns out that the criteria used for testing practical magic ability is faulty for irregulars like Tatsuya.
  • Almost Kiss: Twice. Miyuki nearly kissed him while he was sleeping and they needed to be very close in volume 11 for Miyuki to kill a Parasite.
  • Aloof Big Brother: Was this to Miyuki until she decided to get closer to him.
  • Always Someone Better: A lot of people got massive inferiority complexes after seeing his skills.
  • Accidental Pervert: When he saved Honoka from drowning.
  • Anti-Magic: He is able to use the two strongest Counter Magics Gram Demolition and Gram Dispersion. He also found a way to use Cast Jamming without Antinite.
  • Animal Motifs: Dragon. His Code Name, Oogura Ryuuya means Great Black Dragon.
  • Asexuality: He has almost no sexual lust. He can still feel physical arousal, but avoids actions and thoughts that would cause it.
  • Badass Boast: Gives one before going to fight Blanche's Leader and his minions.
    Mayumi:... Tatsuya-kun, are you planning to fight them?
    Tatsuya: That's an incorrect way to put it. I'm not going to fight them, I am going to annihilate them.
  • Badass Bookworm: Likes reading books. One of the reason he choose 1st High was because of the library.
  • Badass Fingersnap: Combined with volume amplification to beat Masaki in Monolith Code.
  • Be Careful What You Wish For: After the events of Yotsuba Maya's kidnapping the Yotsuba family agreed to the use of Yotsuba Miya's Mental Interference Magic on her own unborn son. The idea was to create the ultimate magician, a person so powerful that he could protect the Yotsuba forever and prevent anymore tragedies such as the loss of over 30 members of the Yotsuba clan in their private war with Dahan including the deaths of key individuals such as the Clan Head. To put it bluntly it worked. Tatsuya was born with the power to literally destroy the world. The subsequent operation to neuter his emotions was to prevent his magic from accidentally going out of control due to an emotional outburst. A large number of the Clan including several branch family heads were terrified of Tatsuya's power. They wanted a magical demigod and got one only to realize that they had a ticking time bomb on their hands. They had planned to execute Tatsuya as an infant only to be overruled by the then Clan Head. Their contemptuous treatment of Tatsuya is a combination of their bitterness at having their hopes fulfilled in such a manner and guilt at what they had tried to do to him and what they had done to him.
  • Being Watched: Sometimes he doesn't even need to use Elemental Sight to know it.
  • Berserk Button: Don't touch his sister.
  • Beyond the Impossible:
    • Flight magic was considered impossible using Modern Magic (it could be done with Ancient Magic) until he discovered a way for Modern Magicians to do it.
    • Elemental Sight allows him to read activation sequences, which is impossible for other magicians; meaning that they can't use Gram Dispersion or his version of Cast Jamming.
  • Big Brother Instinct: Endangering Miyuki is the only way to genuinely anger Tatsuya. The one time Miyuki's life was actually in danger he went on a rampage so devastating it earned him the nickname Mahesvara from the Chinese. He killed their guys so hard an entire nation dare not even speak his name.
  • Big Brother Is Watching: Literally. Can keep an eye on Miyuki at any time with Elemental Sight. Not that she minds.
  • Big Damn Heroes:
    • To save Erika and Mikihiko from the parasite.
    • Also to save Mizuki from being possessed.
  • Blood-Splattered Warrior: After killing a terrorist at Yokohama.
  • Bodyguarding a Badass: As Miyuki's guardian.
  • Born Winner: Even though not everybody can use magic and some lineages are more powerful than others, Tatsuya qualifies. The Yotsuba is the most powerful clan among the 10 Master Clans in Japan. There are two magician lineages in the Yotsuba clan. Some of them are born with a strengthened mind manipulation magic (Miyuki and Miya) and the others are born with a very strong ability. Tatsuya and Maya belong to the latter category.
  • Bridal Carry: Done to Miyuki from times to times. Who totally loves it.
  • Broken Ace: His practical school results aside, he is a Teen Genius and is good at every sports, he is so good that point his friends joke that he is omnipotent. But most of his friends aren’t aware of his troubled past and how Tatsuya views himself because of this operation.
  • Brother-Sister Team: When working with Miyuki.
  • Bullet Catch: Played with in Volume 7, he used his Decomposition on the physical body of the bullets, giving the impression that he was catching them.
  • Bullying a Dragon: Many people take his Course 2 status to mean a lack of ability; while wiser heads acknowledge that regardless, his combat ability is first class, some never do learn the lesson. Most egregious though are those connected to the Yotsuba family. They are well aware that Tatsuya is a strategic class magician and thus Person of Mass Destruction which is bad enough. The fact that his adoring sister Miyuki is slated to be the next head of the House and is a powerful magician in her own right seals the deal. Just how well do they expect to be treated when they have heaped nothing but scorn and contempt on her beloved brother when Miyuki ascends to her position as the head of the Yotsuba?
  • Celibate Hero: Justified. He can't feel emotions like love.
  • Chessmaster Sidekick: During the Nine School Competitions, as an engineer.
  • Chick Magnet: One of the most striking examples of this in the anime, it seems, almost all of the heroines of the show deeply in love with him, including even his own sister. He became more popular with girls after demonstrating his prowess during the Nine Schools Competition.
  • Child Soldier: Joined the army at 13.
  • Clueless Chick Magnet: His lack of a normal range of emotions means that he often misses the hints that a good number of the girls/women around him are romantically interested in him. When clearly faced with a declaration of love, he demonstrates himself to also be a Celibate Hero.
  • Code Name: Oguro Ryuuya.
  • Cool Gun: His CADs, Silver Horn, Third Eye, and Trident, are shaped like one.
  • Covered with Scars: Has many scars all over his body though it's hidden by his clothing.
  • Curbstomp Battle: He won against Hattori in less than 5 seconds. He had made his preparations beforehand though.
  • Death Glare: He gives one to a committee organizer who he catches trying to upload a virus into Miyuki's CAD in episode 17. He's only stopped because Retsu Kudou personally came to the inspection area to see what was the ruckus was, the latter also being displeased that there was someone like that working for him.
  • Declaration of Protection: To Miyuki. Many times.
  • Disintegrator Ray: Can perform this with his Decomposition magic.
  • The Dreaded: Those who know his true powers, most notably the Chinese, are very scared of him. Also, in volume 17, he becomes this to the school after the reveal of their identity as Yotsuba
  • Earn Your Title: Got named Mahesvara after the battle of Okinawa where he restored soldiers who were fatally injured and decomposed completely his enemies
  • Emotion Suppression: He can't feel fully his emotions due to the process that made him an Artificial Magician, leaving him somewhat disconnected from the others his age.
  • Energy Ball: Gram Demolition is a cannonball of Psion.
  • Epic Battle Boredom: Was decomposing his enemies without being attacked even once at 13.
  • Experienced Protagonist: He is still training and becoming stronger but he was already one of the strongest magicians at the start of the story.
  • Gadgeteer Genius: He invents a lot of interesting CAD's that prove to be useful for his friends, such as the flying spell Miyuki uses during the Nine Schools competition.
  • Good Thing You Can Heal: His Self-Restoration will automatically restore his body when he is significantly injured or when an abnormality occurs which reduces his combat ability. He can restrain it through conscious control to punish himself or prevent others from noticing his ability.
  • Goal in Life: His dream is to develop Gravity Control-Type Thermonuclear Fusion Reactor so that Magicians won't be treated as mere weapons.
  • Guns Akimbo: He is one of the few magicians who can use two CADs at the same time. He actually has three CADs—twin pistols and a bracelet-type—during the Newcomers Monolith Code competition.
  • Gun Fu: In anime episode 16 to destroy Masaki's Air Bullets.
  • The Gunslinger/Mage Marksman: Very good with guns and gun-shaped CADs.
  • Healing Factor: To the point of being able to survive a shot through the heart like it was nothing.
  • Healing Shiv: He can apply his Healing Factor (Regrowth) to anyone by shooting you with his gun.
  • Homage: To Batman in volume 12.
  • Humble Hero: Despite his strength and his talents he thinks he is nothing special.
  • Hyper-Competent Sidekick: Hence the reason why most of his Senpais abuse him.
  • I'm Having Soul Pains: Can inflict this with Far Strike.
  • Improbable Aiming Skills/Spread Shot: Can snipe 36 targets simultaneously.
  • Ignore The Fanservice/Not Distracted by the Sexy: See above as to why.
  • Incest Subtext: Tatsuya plays it for laughs. At the same time, his concern for the happiness Miyuki comes to such an extent that it seems to be ready to truly love her as a woman if need be. As a result, he did not even reject her after the declaration of love, saying that he might be able to fall in love with her in the future.
  • Invincible Hero: He always loses against Yakumo but has yet to lose against other opponents. He wishes to remain unbeatable so that Miyuki will be proud of him.
  • Knight Templar Big Brother: If you threaten Miyuki in any way, your life insurance better be paid up.
  • Kung-Fu Wizard: Practices Ninjutsu, although it is considered Ancient Magic.
  • Nice Guy: Despite his stoic and aloof personality, Tatsuya is unfaillingly polite and honest to everyone he meets. Miyuki once said he can be nice to a fault in the strangest of ways.
  • Not Blood Siblings: Played with. Upon his age of majority, the Yotsuba house declares that he is secretly the son of Yotsuba Maya making him Miyuki's first cousin. As marriage between cousins is legal in Japan, Tatsuya is then engaged to Miyuki. This is a legal fiction cooked up by Yotsuba Maya to legalize the sibling marriage. Miyuki is an enhanced magician and thus their pairing would avoid the usual drawbacks of incest with regards to deformities in their children.
    • At the same time, this move still has its own nuances, as Shiba siblings' aunt Maya and mother Miya were identical twins, their genes are the same, so even if Tatsuya really is Maya's son, he is genetically as close to Miyuki as a half-brother would be.
  • Oblivious to Love: He rarely notices when a girl likes him. This is due to Tatsuya's lack of strong emotions.
  • One-Hit Kill: When using Mist Dispersion to decompose the whole body.
  • Person of Mass Destruction: As a Strategic Class magician. His strongest magic "Material Burst" is capable of converting matter to energy according to Einstein's E=MC^2 equation. In theory he could vaporize the Earth.
  • Promoted to Playable: A non video game example. After the schools Monolith Code Team gets badly injured, he's forced to participate.
  • Protagonist Title: He is the Irregular at Magic High School.
  • Razor-Sharp Hand: Can coat his hand with Decomposition magic to tear the flesh of his enemies.
  • The Rival: Seen as one by Masaki and Shinkurou.
  • Role Reprisal: Was played by Yuuichi Nakamura in the Audio drama CD.
  • Savvy Guy, Energetic Girl: With both Erika and Mayumi.
  • Second Year Protagonist: Starting from volume 12.
  • Secret Identity: He is the software developer half of the legendary CAD technician known to the public as Taurus Silver; his mom is the sister of the current head of the Yotsuba clan.
  • The Stoic: Largely due to not being able to show emotions any longer due to various things done to him. However, threatening Miyuki will still set off his Berserk Button and he will show you a Death Glare so terrible you'll regret incurring his wrath.
  • Superpower Lottery: Decomposition magic and Regrowth are very powerful, he also masters the two most powerful Counter Magics. There is Elemental Sight too.
  • Super Soldier: He's an artificial magician and consider a top-secret asset of the military—equaling a strategic weapon like an ICBM.
  • Terror Hero: Due to the mystery surrounding his magics, people tend to be afraid when he uses them and he is fully aware of it.
  • Touch of Death: His Decomposition magic at full-contact.
  • Tranquil Fury: Partly due to not being able to really display emotions any longer.
  • Troubling Unchildlike Behaviour: He was a Child Soldier after all.
  • Tykebomb: Trained since his childhood to be Miyuki's guardian, his mother even removed all his emotions save for his love for his sister so he'll do his best to protect her at any cost.
    • Later in the light novels it is revealed that this was done in order to prevent him from possibly going berzerk and destroying the planet with Material Burst. There was a sizable faction that thought he should be killed outright just to be safe.
  • Underestimating Badassery: People looked down on him because he is a Course 2 student
  • Urban Legend: Many persons think Mahesvara doesn't exist.
  • Vitriolic Best Buds: With Mayumi. Most of their interactions are verbal sparring.
  • Weak, but Skilled: He is this when he is not using his innate magics.
  • What Is This Thing You Call "Love"?: Sometimes wonders what is love since he can't feel it.
  • Willfully Weak: Since he must hide most of his abilities, he can't fight at full power. Granted, a few of his abilities are also not readily available to him. An example would be his Decomposition magic "Material Burst" which requires the "Third Eye" CAD in possession of the military as well as Miyuki removing her suppression effect on his power.
    • The thing about "Material Burst" is that he can use it (Reminiscence Chapter), but he was also in range of the enemy's attack (ships that could launch rockets at 20km). The "Third Eye" CAD just allows him to fire "Material Burst" at a safer distance.
  • Wise Beyond Their Years: Many persons think Tatsuya is too mature for a teenager.

Miyuki Shiba
Voiced by: Saori Hayami
Course: 1
Year: 1st (Volume 1~11), 2nd (Volume 12~)
Class: A
The female protagonist, the younger sister of Tatsuya. She is a member of the Yotsuba clan and the most likely candidate to be the next family-head. As of Volume 16, she is now confirmed to be the next family head. With her brother Tatsuya being her future husband and various circumstances allowing this.
  • Almost Kiss: Twice. She nearly kissed Tatsuya by mistake (she fell) while he was sleeping. Though the situation only came about because she was tempted to kiss him in the first place. Their lips were also very close in volume 11.
  • Aloof Dark-Haired Girl: Whenever things do not relate to Tatsuya.
  • The Ace: Her Magic Power is very high and she can use magic with complex processes very easily.
  • An Ice Person: She specializes in cooling magic.
  • Anti-Magic: Zone Interference, a wide area Counter Magic. Hers is one of the most powerful in the world.
  • Area of Effect: She is better with magic with a large radius.
  • Berserk Button: Don't touch her Onii-sama, or say something bad about him.
  • Big Brother Worship: Let's just say she loves her brother Tatsuya a lot. In particular, Miyuki seems not experiencing any problems with the idea to marry with his own brother and have sex with him if the opportunity presents itself, what is given to understand clearly throughout all story
  • Brother-Sister Team: When working with Tatsuya.
  • Clingy Jealous Girl:
    • She doesn't take it too well when Mari teases Tatsuya about Mibu in episode 4, and starts to freeze up the table around the student council. And she does it again after Mari teases him about Mayumi a moment later.
    • She gives green light to Honoka to go after her brother and sometimes helps Honoka out with this matter.
    • Honoka immediately gets rejected on the spot by Tatsuya when he states that he can never love her due to his lack of emotion towards anyone but Miyuki.
  • Does Not Like Men: Believes her entire body and heart belong to Tatsuya. Going so far as to be disgusted by the concept of being touched by anyone at all except Tatsuya. She also despises the mere notion of marrying anybody but her brother to the point that she breaks out of her nice-girl character in anger and emotional despair.
  • Dude Magnet: Most of the Bloom's think she's the most attractive one of them, so a lot of guys tend to fawn over her.
  • Everyone Can See It: It is painfully obvious that Miyuki's love for Tatsuya isn't sibling love except Tatsuya. He can't see much of anything outside of cold-calculations. Ever since Tatsuya saved Miyuki, she has devoted her life to him. As a result, everything that she does, how she acts/thinks, what she is involved in or what her personality is like, etc. is because of Tatsuya. In short, everything involving/revolving around her, good or bad, is because of her feelings for Tatsuya.
  • Everyone Hates Mathematics: Mentioned in LN Volume 6 that math isn't her strong suit. However, this is only touched upon once in that volume and only that volume. To add to this, no one knows about this struggle she has. And because she is very intelligent according to the sypnosis of the entire series and the stats for her stating that she has a 5/5 for intelligence in official Dengeki media, it is confirmed that she has and still continues to earn stellar grades including Math, meaning that the issue she had in Volume 6 has been fixed.
  • Friendly Rivalry: With Honoka and Shizuku.
  • The Gift: Being from the Ten Master Clan she is naturally this though compared to the others she can even use complex magic for mundane thing with ease and flawlessly. Amazing the others with her talent.
  • Hair Decorations: A hair clip with jeweled snowflakes, given to her by Tatsuya.
  • Hime Cut: She has the traditional hairstyle for a Yamato Nadeshiko.
  • Hopeless Suitor:She's fully aware that Tatsuya doesn't see her as someone of the opposite sex since they are blood-related. She is then informed that she is going to be married to Tatsuya when she becomes the head of the Yotsuba family, much to her extreme approval and happiness. Followed by an explanation of how she is genetically no closer to him than cousins due to extreme genetic engineering.
  • Incest Subtext: Contrary to Tatsuya she really means it. However, later in the 16 th volume of the novel it turns out that as a consequence of a variety of genetic experiments in early childhood, she and Tetsuya completely free from any negative consequences of inbreeding, and their aunt adopts Tetsuya and announces it to his son, effectively turning them into cousin brother and sister, thereby opening up the possibility for their subsequent marriage.
  • Informed Attractiveness: Everyone calls her the most attractive of all the girls and she does look really nice to many fans of the series. She is cute , but compared to Honoka and Mari, its a bit hard to take seriously in the beginning of the series. However, she does really show the kind of beauty they have (and when seen from a Japanese perspective it's true since she is the best example of Japanese beauty, in other words Raven Hair, Ivory Skin).
  • In-Series Nickname: "The Queen" and also the "Snow Queen".
  • Japanese Sibling Terminology: Uses "Onii-sama" to call her brother. She was using "Ani" before starting to respect him.
  • Lady of Black Magic: Her magic is specialized for covering a large area and is very powerful.
  • One Woman Army: Her AoE magic is totally suitable for this task. She cleared out an entire warehouse full of armed soldiers, with one spell.
  • Perfectly Arranged Marriage: To Tatsuya. Although technically her brother, she was so heavily genetically modified that her theoretical incestuous relationship with his brother will not have any negative consequences It may also be somewhat one-sided though, as the other half has stated that he only sees her as a sister and promised that he will try his best to love her as a woman. Despite his promise, so far, he's still only thinking of her just as a little sister.
  • Playing with Fire: Inferno magic.
  • Power Incontinence: When she gets emotional things around her tend to get frozen. Explained in the novels in that Miyuki is using 50% of her power to suppress Tatsuya's magic. The moment she releases the seal, she gains full control on her magic.
  • Protectorate: Tatsuya's duty is to protect her.
  • Raven Hair, Ivory Skin: She is black-haired and pale-skinned, and everyone calls her the most attractive of all the girls.
  • Role Reprisal: Was played by Saori Hayami in the Audio drama CD.
  • Satellite Character: Miyuki's character is mainly based on her relationship with Tatsuya. She actually invokes this though, because she feels she has to.
  • Secret Identity: Must hide that she is a Yotsuba.
  • Ship Tease: Considering her feelings for him, most of her moments with Tatsuya are this.
  • The Sixth Ranger: Even though she spends more time with Tatsuya she qualifies by not being one of his classmates. Her two friends too.
  • So Beautiful, It's a Curse: She is such a Dude Magnet that she can't go out without being approached by various persons.
  • Stepford Smiler: Can wear an archaic smile to hide her feelings.
  • The Tease: Never really stated but it's quite obvious she tries to tease Tatsuya by wearing sexier outfits at home.
  • Third-Person Person: When with her brother.
  • Tranquil Fury: Even better at it than her brother. And she is noted to be very scary when in this state. Obviously, it is because of her feelings for Tatsuya, which she had developed since Tatsuy saved her from dying after being shot during the Defensive Battle in Okinawa, and those feelings cause her to be angry or emotional whenever she is oogled at by other guys or when other girls get close to Tatsuya.
  • Yamato Nadeshiko: She is the embodiment of this.
  • Yandere: (Down-)Played for laughs, though; she isn't actually dangerous to her brother's many admirers, but a lot of people are actually scared of her.

     Minami Sakurai

  • Generation Xerox: Honami was Miya's guardian. Now she is occupying the same role for Miyuki, Miya's daughter.
  • The Gift: Her talent is comparable to the Saegusa twins despite not being from being from the Ten Master clans. Her barrier even rivals Phalanx.
  • Shipper on Deck: Ships Mayumi and Tatsuya as a solution for Izumi who wants Miyuki to become her Onee-sama.
  • Twin Maker: She is the niece-clone of Honami Sakurai.

Towards Tatsuya when he also helps Angelina and Mayumi hunt down the vampires in Volume 10. When confronted by Mizuki, it turns out that Erika's been waiting for him to make the first move.
  • Curbstomp Battle: Mibu stood no chance against her, even when she used a real sword against her.

  • Red Oni, Blue Oni: Red to Mizuki's and Mikihiko's Blue. She is Red to everyone.
  • School Sport Uniform: She wears one during an early episode but since the series is set in the future, it is considered to be a severely outdated style not commonly worn anymore.

  • Meganekko: Her glasses actually act as a power limiter for her eyes. Mizuki is a smart person and that means she knows when to take off her glasses.
  • Properly Paranoid: After Mari's accident she decided to remove her glasses while watching the NSC despite Erika's recommendation to not do this since it's painful for her.Thanks to this, she noticed an abnormality with Kobayakawa's CAD which permitted Tatsuya to bust one of No Head Dragon's mole.

She's completely flustered while ardently declaring that she can't possibly be in love with Tatsuya. Taken Up to Eleven. She insists that she just sees him as a younger brother... when he has a brocon younger sister. The Irony. Mari collapses at the table due to her completely unconvincing act.

Masaki Ichijou
Year: 1st (Volume 1~11), 2nd (Volume 12~)
A first year at third high, son of the Ichijou of the Ten Great Clans, known for participating in real combat. Has a crush on Miyuki.
  • Anti-Magic/Attack Reflector: Armor of Interference can do both.
  • A Taste of Defeat: Lost for the first time against Tatsuya.
  • Bishōnen: The audience gets to quickly see his body from his shower scene in episode 7. He's an athletic adolescent male with slender glabrous legs, a compact waist, and a toned but lithe upper body with a soft boyish face. Definitely a bishonen.
  • Brains and Brawn: He is the brawn, Shinkurou is the brains.
  • Blood-Splattered Warrior: Fits him to a T. His Red Baron is a reference to this trope.
  • Drama-Preserving Handicap: As an ability that can literally One-Hit Kill any human, Rupture is naturally banned from use in Monolith Code, rendering Ichijo merely a really strong opponent instead of an unstoppable killing machine.
  • Earn Your Title: Earned the title of Crimson Prince after a battle where he was bathed in blood.
  • Expy: Of Suzaku Kururugi from Code Geass.
  • Having a Blast: Can do this asily with Rupture as long as there is some liquid within his target.
  • Hopeless Suitor:
    • Miyuki is too much of a brocon. She is also disgusted by anyone but her brother Tatsuya even touching or complimenting her, believing that she belongs to her brother in both body and heart. She also despises the mere notion of marrying anyone but her brother to the core, as evident when Miyuki and Tatsuya officially become engaged after Miyuki is announced the next head of the Yotsuba family. Masaki's father objects this and then tries to arrange a marriage between Masaki and Miyuki. Miyuki upon hearing about this breaks her nice-girl personality on the spot to immediately and aggravatingly refuse this. To which she is reassured that the Yotsuba family has no intentions to ever stop Tatsuya and Miyuki's marriage.See Below
    • Miyuki is also already engaged to the one person on the planet she actually wants to marry.
    • It is also stated that Miyuki's sheer existence was solely to be Tatsuya's Spouse and for them to remain beside each other for their entire lives. She was conceptualized and genetically engineered specifically for this purpose, so that Miyuki was strong enough to restrain Tatsuya's true power and also be genetically compatible with him to do regular marriage things like produce children to continue the strength of the family bloodline. It is also stated that if Tatsuya loses Miyuki for any reason his mind will "break" and he will destroy the world.
  • The Juggernaut: Defeated all the students of Eight High while maintaining his Armor of Interference. His performance was noted to be similar to Katsuto's style.
  • Love at First Sight: After seeing Miyuki. He is not the first one.
  • Love Makes You Stupid: He started acting bizarrely after encountering Miyuki.
  • Mistaken for Gay: By his little sister. Thinking that he spends too much time with George.
  • Mr. Fanservice: The anime added a scene with him taking a shower.
  • Naked on Arrival: He debuted in the anime with a shower scene detailing his lithe upper body.
  • One-Man Army: His power was evaluated to be that of an entire battalion by Kazama. He killed a lot of enemies at 13 and at Yokohama too.
