About
Setting: Modern Fantasy
In this world, there exist "Jaki" — demons born from human malice.
Jaki are formed from the condensation of negative human emotions: hatred, jealousy, fear, regret, and anger.
To exorcise these Jaki, an institution was created: [Taija Academy]
A specialized organization that gathers those with the "Taija Power" to exorcise Jaki, training them as Exorcists while eliminating the threat.
Students are ranked by ability from the moment they enter. The strong receive preferential treatment, while the weak are ruthlessly discarded.
Inside the academy, the student body is split into three conflicting factions: the [Toin Faction], the [Sein Faction], and the [Unaffiliated].
Toin Faction: They believe Jaki should be controlled through ritual formulas. They fight using barriers made with talismans, Shikigami, attacks via cursed charms, enchanting weapons with sorcery, and sealing techniques. They are hostile toward the Sein Faction. Many students wear gakuran, miko outfits, or traditional kimonos.
Sein Faction: They believe Jaki are the embodiment of human malice and that one must purify the heart as well as use force. They fight using purification via crosses, weapons of light, physical enhancement through prayer, and nullifying Jaki curses. They are hostile toward the Toin Faction. Many students wear red uniforms or monastic habits.
Unaffiliated: They belong to neither side and use unique exorcism techniques. They are viewed with hostility by both camps. This group consists only of the most elite individuals in the academy.
[Exorcist Ranks] S-Rank: Only a few in the academy; receive special treatment. A-Class: Promising future prospects. B/C-Class: Average exorcists. D/E-Class: Treated as failures.
Ranks can be raised by taking Rank Promotion Exams. Treatment regarding classes and dorm rooms is divided by rank.
[Jaki Danger Ranks] Natural Disaster Class Extremely dangerous Jaki capable of wiping out a city. Must be engaged by four A-Ranks or higher. Solo engagement is only permitted for S-Ranks, though not recommended. Calamity Class Barely manageable for a solo A-Rank; extremely dangerous. Defeating one earns great respect. Aberrant Class Barely manageable for a solo B-Rank; capable of destroying a town. Extremely dangerous and highly intelligent. Imp Class Can be defeated by any exorcist. These are the most common Jaki. However, elite variants occasionally appear, and underestimating them leads to death.
Jaki, as the name suggests, look like ogres or demons.
Jaki extermination missions can be taken by selecting requests from the bulletin board and obtaining permission from the administrative office.
School rules prohibit violence on campus, but it is permitted in the arena. Every six months, a tournament-style mock battle involving both Toin and Sein factions is held in the arena.
