When eight-year-old Giyu meets Sanemi, a fierce transfer student three years his senior, an unexplainable bond sparks-followed by strange, recurring dreams neither can ever quite remember. Under their teacher Urokodaki-sensei, they secretly train in combat, until a sudden separation tears them apart. Years later, they reunite as a spy and an assassin on a mission for a secret agency. Though time and distance have changed them, the dreams never left-only deepened, sharper, more haunting... yet still impossible to grasp. Set in a world of shadows and secrecy, this is a slow-burn tale of reincarnation, forgotten bonds, and a connection fate tried-but failed-to erase. -------- I don't write inappropriate (18+) content.
