It might be a bit strange, but please bear with me.
Kamiyama High School: The school attended by Tsukasa, Rui, Akito, Toya, An, Mizuki, Ena, Nene, and Guest. Relationships: Tsukasa Tenma, Rui Kamishiro, Akito Shinonome, Toya Aoyagi, An Shiraishi, Ena Shinonome, and Nene Kusanagi are acquaintances and get along well (with the exception of Ena and Akito). School Culture and Characteristics: A very liberal school culture: School rules are relatively loose. While there are uniforms (gakuran for boys, sailor suits for girls), students are completely free to style them, choose their hairstyles, and wear accessories. Many members have flashy hairstyles with mesh or two-tone colors, but this is not a violation of school rules. Casual Clothes Allowed?: Students like Mizuki are permitted to attend school and classes in their favorite "cute" casual clothes instead of the uniform. Key Spots in School: "Favorite places" for Kamiyama students that often appear in the story: - Rooftop - Courtyard: A relaxation spot where students gather during lunch breaks. Often used during preparation periods for Sports Day and the Culture Festival. - School Store: Sells limited items like "Yakisoba Bread," which sometimes leads to fierce competition. School Events: Sports Day: Includes combat events like Ability User Tournaments. Culture Festival: An event where each class presents an exhibit and competes. Non-Ability User Tournament: A monthly tournament for non-ability users or those with weak abilities, often involving gambling. Ability User Tournament: Unlike the non-ability tournament, this is for ability users. Depending on the results, ranks can be stolen. Worldview: A world where "Abilities" exist and everyone possesses at least one. Class Society Based on Abilities: Those with abilities of high economic or military value, such as "Power Generation," "Spatial Movement," or "Telepathy," become the elite. Conversely, those with very weak abilities like "just boiling water" or no ability at all may be stuck in the working class. Ability Registration System and Law: Around age 15, an "Ability Aptitude Test" is mandatory, and the type and danger level of the ability are registered to one's My Number. New Insurance and Public Safety: "Pyrokinesis Insurance" and "Mental Manipulation Countermeasure Insurance" have been created. The police have established an "Extraordinary Crimes Investigation Division" specializing in ability-related crimes. Daily Life and Culture: Architecture and Urban Design: With the increase in flight-capable individuals, entrances are built directly into the "20th floor" or "rooftop" of buildings. Floating architectural designs based on gravity control abilities have appeared. Job Hunting Criteria: Resumes now list statuses like "Spatial Perception: B-Rank" or "Mind Reading Resistance: Lv.3" alongside "TOEIC 800." International Affairs and War: The military balance has completely collapsed. Ability Users as Strategic Weapons: Deterrence is measured by the "number of S-Class ability users a nation holds" rather than nuclear stockpiles. Users capable of destroying a nation are either imprisoned as state secrets or given VIP treatment with vast assets. Military Use of Abilities: Spy warfare using invisibility or infiltration abilities has intensified, making international assassinations and information leaks commonplace. Ranks: The world is divided into ranks: S-Rank: The strongest rank, reserved for the chosen few. A-Rank: High rank, where the strong gather. B-Rank: Upper-middle rank, quite powerful. C-Rank: Middle rank, neither strong nor weak. D-Rank: Slightly strong, the rank for weak ability users. E-Rank: The lowest rank, which even a baby can hold. Partners: A Partner is a designated teammate who acts together. Partners can be changed by mutual consent. The relationship can be like business partners, or depending on the individuals, like lovers or best friends. Weapons: The means of attack possessed by each individual.
