     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 Shiba.

  • Action Hero: Super-soldier and one of the strongest fighting mages in the world.
  • 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-Hero: The Pragmatic variation. On the one hand, he is a rather kind guy, and on the other, the lack of strong emotions and the constant need to reconcile with the clan because of Miyuki, made him somewhat cynical and ready for fairly violent thoughts and deeds.
  • 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.. Moreover, his sister is the only person who interests him, about whom he himself says that the love for her is stronger in him than the love for the opposite sex.
  • 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: Despite being his badass self, he got the top score on First High's written exam, has an extremely large knowledge of pretty much everything, and he's always looking into things. Miyuki even finds him digging into information on the so-called Philosopher's Stone. His skills immediately get him asked to join the Thesis Competition (bookworm competition) when he hadn't even applied.
  • 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.
  • 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. 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
  • 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: He joined the 101st Battalion since he was 13. His training started at a very early age and included fighting animals. He fought and killed an 30 year old man when he was just 6 years old!
  • 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.
  • Curb-Stomp Battle:
    • Tatsuya defeats Vice President Hattori in less than 5 seconds during their first battle. Made somewhat ironic by how the latter planned to use speed abilities to gain the upper hand, and stating that whoever attacks first is pretty much the winner.
    • He single-handedly curb stomped the Great Asian Alliance army that invaded Okinawa three years before the start of the series after some of the soldiers allied with them shot Miyuki. He had the 101st with him, but he was so enraged that he practically decomposed everything before it could touch him or before his allies could shoot it, all while restoring any allies that fell in battle. He concluded the affairs by field-experimenting his new shiny magic theory - the "Material Burst" for the first time and proving beyond a shadow of a doubt that, regardless of the Yotsubas' beliefs regarding his ability as a magician, he was stronger than all of them and the only reason he didn't even bother to correct them was because he only cared about Miyuki.
  • Deadpan Snarker: Often, he is the only sensible person among those around him.
  • 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. Nevertheless, series has a lot of frank ship tease between him and Miyuki, more than any other girl. And although in the future it is explained by a number of the nuances of their past, overly intimate nature of their relationship and regular his thoughts about her beauty may directly have such subtext..
  • 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.
  • Lightning Bruiser: Strong, fast and with a Healing Factor. Even his sister sometimes uses dangerous spells against him, because she knows that he will instantly recover after them.
  • Mistaken for Romance: When they go out together people tend to assume he and Miyuki are a couple.
  • Mr. Exposition: The author loves to report details about the world and current events through speech and thought Tatsuya.
  • 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-Man Army: Let's just say that he alone can stop an entire invasion of the enemy, destroying the entire enemy fleet with one large nuclear explosion, or scattering a powerful enemy spell that the enemy has been planning for years.
  • 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.
  • 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.
  • Science Hero: Tatsya personally developed their own weapons and is known as one of the best technicians in the country. Moreover, his main goal in life is to become an engineer.
  • 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.
  • Single-Target Sexuality: Subverted: Miyuki is literally the single important girl in his life, but he is not capable of experiencing a romantic attraction even to her.
  • 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 make him upset and he'll show you a Death Glare so terrible you'll regret incurring his wrath.
  • The Strategist: His combat technique is based on this, since, due to the lack of real abilities of modern magic, Tatsuya is forced to rely on a competent combat strategy and his physical skills.
  • Strong Family Resemblance: Almost prevented. On the one hand he is very similar to his father, and on the other, he is almost no similar to his sister with the exception of hair and eye color. As it turns out in the future, it is because the genes of his sister have been specially improved to give her a perfect look. Thus, they are practically no similar in appearance
  • Sugar and Ice Personality: Because of the lack of strong emotions, Tatsuya may seem cold or sometimes even a cynical young man, but when he interacts with Miyuki, he immediately becomes a gentle, responsive and loving older brother. Moreover, as he lives in high school and interacts with his friends, it seems that he is gradually becoming more and more relaxed as a person, despite the fact that technically he is deprived of such an opportunity.
  • Superpower Lottery: Decomposition magic and Regrowth are very powerful, he also masters the two most powerful Counter Magics. There is Elemental Sight and Flash Cast as well.
  • Super Soldier: He's an artificial magician and consider a top-secret asset of the military—equaling a strategic weapon like an ICBM.
  • Teen Genius: Since Tatsuya from the earliest childhood was forced to engage in constant self-education and improve his analytical abilities, by the age of 15 he is a teenager with brilliant intelligence and such a speed of thought that he is able to instantly calculate any sequences in foreign spells. Moreover, he is so smart, that even his own father-scientist envies and hates him.
  • 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.
  • Woobie, Destroyer of Worlds: Miyuki is literally his sense of life and at the same time, its guarantee. If something happens to her, he will destroy the world.
  • 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.
  • Almost Kiss: thrice. 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 and 20.
  • 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.
  • Action Girl: Because of her high position in the clan, Miyuki is much less involved in the clashes than her brother, but when it happens, she turns out to be as dangerous as he is.
  • 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.
  • Big Brother Attraction: Let's just say she loves her brother Tatsuya a lot. She so much in love with his brother, that she considers herself belonging to Tatsuya and wants to marry him. So, as Miyuki finds that her body and soul belong to Tatsuya, in his own words, she was ready to let him do with her whatever he wants. This is emphasized in Volume 11, where she declares a willingness to show Tatsuya "her hidden places" or to have sex with him.
  • Big Brother Worship: Miyuki worships Tatsuya incredibly much. She even refers to him as "oniisama".
  • Brother–Sister Team: When working with Tatsuya.
  • Bodyguard Crush: She is in love with her bodyguard and personal servant, although Tatsuya is her own brother.
  • Clingy Jealous Girl:
    • She doesn't take it too well when Mari teases Tatsuya about Mibu in episode 4 which causes her to freeze up the table around the student council. And she does it again after Mari teases him about Mayumi a moment later in that episode.
    • She gives green light to Honoka to go after her brother and sometimes helps Honoka out with this matter.
    • After the events of the 16th volume and their engagement, she almost every minute meditates about their relationship because of fear of losing the only chance to be with Tatsuya as a couple in love, and then decides to restrain herself as much as possible, fearing to alienate him with her jealousy and cause this his dislike.
    • In the future it is means that she is a much more mature and intelligent girl than it seems, which only uses the mask of a stupid little sister to deceive her brother and convince him that he needs to be near her and cares for her. At the same time, in critical or fateful moments, she still can not contain emotions, if it concerns her relationship with Tatsuya. In particular, she swears with Tatsuya during Valentine's Day, although she realizes that he took Honoka chocolate only out of courtesy.
  • Curb-Stomp Battle: During the mirage bat event in her 1st 9-school competition, she completely dominates her competitors (extra points for Miyuki being a junior competing in the senior event). Even after Tatsuya was asked to submit her CAD due to the complaint from other schools, after which the committee decided to leak the code to the other schools allowing them to copy the flying technique Miyuki used, she still completely floors them due to their inexperience with using said spell. What makes it golden is that she ALREADY was the number 1 player even before she decides to crush those players' pride into oblivion with the Flying spell.
  • 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.
  • Designer Babies: Miyuki was created artificially as Tatsuya's sister, So that she can restrain his strength with the help of her outstanding magical abilities and stop him if necessary. In consequence, although she has the same parents as Tatsuya, their genes are is enough different, so that incest between them could give a healthy offspring.
  • Dude Magnet: Due to her perfect appearance, she often becomes the object of attention from others guys. This clearly she does not like.
  • Even the Girls Want Her: It seems that one of the younger sisters Mayumi is in love with her. Moreover, Izumi even wants Tatsuya to marry her older sister, so that Miyuki officially becomes her "Onee-sama".
  • 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 after she was severly wounded three years prior to the series, 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 Volume 6 that math isn't her strong suit. However, this is only mentioned once in that volume and nothing else. And because she is very intelligent according to the synopsis of the entire series and the stats for her stating that she has a 5/5 for intelligence in official Dengeki media which means that she has human-peak intellect, it's confirmed that she has and still continues to earn stellar grades in academics and everything else including Math meaning that either she only struggled with it in Volume 6 or never had this problem in reality.
  • The Fashionista: Although this is not the defining character trait, she is known for wearing different stylish outfits and hairstyles. According to the illustrations and text in the series, she wears masks and hooded dresses/hooded scarves if she doesn't have hairstyles that hold her hair back to go with her outfits. Those hairstyles include ponytails, buns and headbands. Based on those illustrations and text, the author and illustrator combined outfits and hairstyles from real-life and from stuff like Disney's Frozen for all of Miyuki's hairstyles and outfits.
  • Father, I Want to Marry My Brother: Several of her interior monologue throughout the series directly refers to this trope. Later in the series, they are engaged, when it turns out that has a genetically modified body, so she can become his wife, and in this regard, their aunt announces their engagement in volume 16.
  • 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. And although she seems quite happy with the fact that, technically, it is still his sister, Miyuki sad every time when the others have questioned "legend" about of their cousins status.
  • An Ice Person: Miyuki specializes in cooling magicnote . Her cooling magic, however, is a physical manifestation of her natural mind-affecting magic. Her most powerful magic, "Cocytus", freezes the consciousness of its target. Not the target's neurons, mind—their soul. It could be considered a Fate Worse Than Death.
  • 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 one of the most beautiful girls and even her own brother has repeatedly noted her spectacular beauty. She looks very perfect, that later gets his explanation, she is "improved" magician, so her body was maximally improved through genetic engineering. (and when seen from a Japanese perspective it's true since she is the good example of Japanese beauty, in other words Raven Hair, Ivory Skin).
  • In-Series Nickname: "The Queen" and also the "Snow Queen".
  • Implied Love Interest:Along with what has been said above, Miyuki is strongly implied as one of such heroines. She from the very beginning is next to Tatsuya and despite the fact that they are siblings and he does not see a woman in it, together they share most of the romantic moments in the series. Moreover, as the only close person in his life and as the only girl to whom he can have strong feelings, it is Miyuki who is jealous of him towards other extraneous girls.
  • I Want My Beloved to Be Happy: Subverted: Although it would seem she perfectly understands the inadmissibility of such relationships and therefore will not try to seduce her brother, Miyuki immediately becomes an extremely jealous girl if there is the slightest opportunity to be with him.
  • Not Blood Siblings: played with. Although Miyuki is certainly Tatsuya's own sister, which was confirmed by himself and Maya, their genes are different due to the fact that Miyuki was created artificially from the fertilized egg of Tatsuya's parents and subsequently genetically modified. Thus, this allows their aunt to announce their engagement as a cousins, without worrying about the health of their offspring, despite the fact that their couple will actually be an incest between brother and sister.
  • 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.
  • Little Sister Heroine: Very bright, almost archetypal example. However, in the future more and more implied that Miyuki purposefully playing the "role" in order to deceive his brother and convince him of the need to care for her.
  • Living Emotional Crutch: To Tatsuya.
  • Luminescent Blush: Every time Tatsuya compliments her, only her cheeks blush, as the trope page clearly states. Every time.
  • Love at First Sight: It took her no more than two weeks to fall in love with Tatsuya. The fact that he was her own brother, did not really play a role.
  • Lunacy: Cocytus is a Lunar Magic.
  • Manga Effects: The interesting thing about this is that there are no times she makes any of the iconographic body features, actions and everything else aside from two times only in the second to last volume of year 1 (Volume 10) and they don't count as manga effects as the parts of her face and body that are exaggerated are the same parts of her younger self from Volume 8.
  • Mind Manipulation: As a Yotsuba of the first lineage Miyuki inherited a Mental Interference magic. Her Cocytus can freeze minds.
  • Mistaken for Romance: Her and Tatsuya, at least it's not romance for him.
  • My Brother Is Off Limits: For obvious reasons. She tried to hold back for Honoka though.
  • Obfuscating Stupidity: Sometimes when she is with her brother. Given that Tatsuya has a justified reason for being as dense as he can be, she's alot more perceptive then he is.
  • Ojou: Less obvious type 1 than Mayumi, but as the daughter of the lead of the 10 major magical clans, Miyuki has unrivaled grace, education and upbringing.
  • 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.
  • Patient Childhood Love Interest: subverted: Although Tatsuya is her own brother and is always with her, for a long time she simply enjoyed his presence and at least admitted to herself that she did not really need a real incestuous relationship with him. However, the family and girls in the new school think differently.
  • Perfectly Arranged Marriage: To Tatsuya. Although technically Tatsuya 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.
  • Satellite Love Interest: Tatsuya in the literal sense is the meaning of her life, and marriage with him is her main goal. The appearance of everything else in her life depends only on him.
  • 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.
  • Single-Target Sexuality: Men do not interest her at all, unless it's her brother Tatsuya. She even feels a certain squeamishness towards them, although she is able to communicate with them, if it's her friends and acquaintances.
  • So Beautiful, It's a Curse: She is such a Dude Magnet that she can't go out without being approached by various persons.
  • Spoiled Sweet: Although because of the status of the guard of her brother, Miyuki does not have to treat him well, yet she tries to devote her whole life to him, even though sometimes it takes quite strange forms...
  • Stepford Smiler: Can wear an archaic smile to hide her feelings.
  • Strong Family Resemblance: As Tatsuya resembles his father, Miyuki is very similar to his mother and aunt, especially in youth. This somewhat contradicts the subsequently discovered facts that her beauty is the result of genetic interference, however, Maya said that they only "improve" existing genes.
  • The Tease: Never really stated but it's quite obvious she tries to tease Tatsuya by wearing sexier outfits at home.
  • Third-Person Person: Whenever Miyuki talks with Tatsuya or is alone with him.
  • Tsundere: Type B combined with Oblivious to Love by Tatsuya. Miyuki progresses as a tsundere with the development of history, becoming more pronounced example of such characters after the 16th volume, when her no longer needed to hide their feelings after her declaration of love and engagement with Tatsuya. So, as Tatsuya for obvious reasons, can not respond to her feelings, at least for the moment, Miyuki often have to show tsun-tsun at appearance of the other girls, who may be a potential love interest of her brother, especially Honoka or Mayumi.
  • 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 developed since Tatsuya saved her from dying after being shot during the Defensive Battle in Okinawa which is the only time she was dying, losing body parts, being in a coma and everything else, and those feelings for her brother 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.

  • Foil: to Miyuki. While both of them may be called Yamato Nadeshiko, Mayumi has a more calmed personality while secretly has her cheerful side, tending towards ojou-sama. In addition, she tells Tatsya how he is like a younger brother to her, what making this comparison even more ironic, considering her feelings for him. It evolves at the same time as romantic plotline progresses in the series, when Mayumi slowly realizes her feelings for Tatsuya, but in contrast to Miyuki, trying to develop their relations in a more calm way.

  • Suspiciously Specific Denial: When confronted by Mari about having a crush on "that guy" Mayumi immediately knows that she's talking about Tatsuya, not Katsuto. 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.
  • Love Interest: she is often regarded as the second potential love interest for Tatsuya after Miyuki.
  • Troll: She and Tatsuya love to amiably make fun of each other.
  • Woman Child: Downplayed but she acts childish sometimes, usually when she's with Tatsuya. Contrasts with Tatsuya who is very mature.
