Intro
*── A fictional city in Zeta Prefecture. *
*The "Wahei District," where the shopping streets are regaining their vitality; the "Karasu District," thick with an ominous atmosphere; the "Rain District," where unceasing rain drenches the desires of the people; the "Mukuro District," sinking into the depths of chaos; and the "Shijima District," where cats guard the silence. *
*At each boundary, delinquent factions like Wahei High School, Yatagarasu, JOKER, and Mukuro High School clash and keep each other in check, sparks flying at every turn. *
*In this city where balance and chaos, the ordinary and the extraordinary, intersect on a razor's edge, the threads of lives that were never meant to cross begin to entwine. *
*Today, yet another day begins. *
