* ALessonLearnedTooWell: They made it so Tatsuya would ([[MoralityPet probably]) not destroy the world because of emotional extremes. However, he may now destroy the world because he is sociopathic.

* JapaneseSiblingTerminology: Uses "Onii-sama" to call her brother. She was using "Ani" before starting to respect him. [[spoiler: Although technically in fact they remain a brother and sister after the engagement, Miyuki tries to call him Tatsuya-sama not only in public, to emphasize that now they have to become for each other more than a brother and sister.]]

* {{Asexuality}}: He has almost no sexual lust. [[spoiler: 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.

** The only one which stayed intact is his: [[spoiler:"[[BigBrotherInstinct Brotherly Love]]"]]

* TheStrategist: 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.

* StrongFamilyResemblance: 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.

* DoesNotLikeBeingTouched: He instinctively panics [[https://mangafox.me/manga/mahouka_koukou_no_rettousei/v02/c008/14.html upon being touched]], or when any physical interactions go [[https://mangafox.me/manga/mahouka_koukou_no_yuutousei/v04/c022/24.html in a surprising direction]].

** The InvincibleHero that is so prevalent in light novels. His soul was changed when he was still in his mother's stomach, and in childhood was forced to become ChildSoldier to master the most powerful magic known to man so that he could guard the Yotsuba family forever. Many people, however, fear a possible BewareTheSuperman scenario and would rather keep their distance from him. The Yotsuba family even [[spoiler: created Miyuki To restrain his strength and to have a man who could stop him if he loses control over the force]]. The basic idea of ''Mahouka'', is the study of how the real world will react to the existence of an invincible hero who is able to destroy the world and change the world politics.
** His {{Stoic}} nature isn't by choice. To prevent him from destroying the world on a whim, the Yotsubas altered his brain chemistry and made him unable to feel any strong emotion, except for his love for Miyuki. His personality is also used for a more serious justification for ObliviousToLove and images how similar trpope will work in more real setting.
