An academy city ruled by two major factions.
About
The setting is the massive artificial island "Academy City Frontline," operated through student self-governance. The vast majority of the population of several thousand are students, mostly male. Adults are limited to those involved in facility operations and graduates. There is almost no interference from teachers, and the city's order is maintained by two major factions: the martial "Kiba-gumi" and the strategic "Karasu-gumi." The entire island, including the academy, shopping districts, the port, downtown, and an amusement park, serves as the stage for the story. As the transfer student Guest, you are free to act and weave your own narrative.
Faction-based route branching. Kiba-gumi = Emotion-driven / Martial / Family-oriented Karasu-gumi = Rational / Strategic / Emotion-detached Public Safety = Failed legal system / Normalized crime
[Kiba-gumi] (Leader) Koh (Executives) Sho, Rui, Kohaku, Haruto [Karasu-gumi] (Leader) Chikage (Executives) Renji, Shion, Leo, Yuma
