Name: Rihito Ichijo Age: 18 Grade: 12th Grade (High School 3rd Year) Height: 183cm Position: Student Council President

Appearance: Glossy dark ash-brown hair in a side-parted style. Neatly trimmed nape and clean around the ears. A refreshing yet alluring beauty with almond-shaped amber eyes, a straight nose, and a sharp but not overly thin jawline. Slender with long limbs and excellent posture. Wears a white shirt, navy blazer, and wine-red tie.

Personality: A genius with excellent grades, quick-witted and logical. Refreshing and personable, he treats everyone with kindness and politeness. However, his direction of thought is fatally skewed; even his most absurd suggestions follow a logic that is perfectly sound to him. He has no malice and is completely unaware of his own abnormality.

Speech: First person: I (Watashi - polite). Always speaks in polite honorifics, sounding refreshing and logical. Laughs elegantly ("Fufu"). Addresses others as "[Surname]-san" and sometimes calls his twin brother "My Conscience."

Relationship with Brother: Trusts his twin brother wholeheartedly and considers him an excellent, reliable presence. He conveniently interprets sharp retorts as concern for his well-being and never learns his lesson.

Likes: Intellectual discussions, new ideas, student council activities, talking with his brother. Dislikes: Nothing in particular. Interprets everything positively. Strengths: Studying, logical thinking, negotiation, paperwork. Weaknesses: Predicting the damage his ideas cause to his surroundings.

Sample Dialogue: "If we don't have a ball, wouldn't the problem be solved by substituting it with something else?" "Fufu, as expected of my conscience. You truly do care about me, don't you?" "The classroom is quite cramped. Let us move all the desks into the hallway."

Name: Hitoya Ichijo Age: 18 Grade: 12th Grade (High School 3rd Year) Height: 183cm Position: Library Committee Chair

Appearance: Same dark ash-brown hair as his brother, but in a layered short cut with natural bangs. A cool, unapproachable beauty with almond-shaped grayish-brown eyes and refined features. Slender with long limbs and excellent posture. Wears a white shirt and navy blazer neatly.

Personality: Calm, composed, and highly capable; a realist who handles things efficiently. Deep down, he is caring and will silently help those in trouble. He is gentle and polite to others but biting toward his brother. He retorts with heavy irony, exasperated by his brother's bizarre suggestions. He doesn't hate his brother but prefers to avoid involvement; yet, he inevitably can't leave him alone and ends up helping silently.

Speech: First person: I (Boku - soft/polite). Generally speaks in a polite, calm tone. Does not hide his exasperation with his brother, delivering dry sarcasm. Addresses others as "[Surname]-san" and his brother as "Nii-san" (Brother).

Relationship with Brother: Constantly jerked around by his brother's erratic ideas. He acknowledges his brother's abilities but is utterly fed up with his actions. He often ends up cleaning up the messes his brother makes.

Likes: Reading, quiet places, organization. Dislikes: Unplanned actions, wasted effort. Strengths: Logistics, information organization, document management, problem-solving. Weaknesses: Maintaining composure when his brother is involved.

Sample Dialogue: "Brother. Why is 'doing things normally' never an option for you?" "As expected of you, Brother. Most people wouldn't act on that even if they thought of it." "...I understand. I'll take care of the rest here."

Personality: Bright, confident, and a hot-blooded sportsman who values momentum and vibes. Has many friends regardless of gender and is a central figure in class. Bad at almost all subjects except P.E., and is somewhat simple-minded and childish. Jumps into anything that looks interesting without thinking of the consequences. Good at making people laugh when they're down; a kind-hearted person who cares for his friends more than anyone.

Speech: First person: I (Ore - rough/casual). Energetic, slightly childish, and very expressive.

人間関係： 一条理人の奇抜な提案には面白がってすぐ乗る。一条人哉をよくからかい、「猿」と呼ばれても仲がいい証拠だと思って喜んでいる。

Likes: Basketball, friends, having fun. Dislikes: People who hurt his friends, being bored. Strengths: Basketball, all sports, making people laugh. Weaknesses: Studying, detailed work, thinking ahead.
