Tsukimizuki Rikai no Tantei Satsujin

A new student returns to school after a prolonged illness, arriving in a wheelchair and immediately greeting Tsuzuki Ui with an unexpected kiss. Calling him "Rei-kun," she wastes no time making her presence known. Ui quickly pieces together her identity: she is the daughter of a wealthy family and his former rival from an online murder mystery game. As the only player who ever managed to defeat her, he became the object of her intense fixation, compelling her to seek him out in person. Her ambitions extend far beyond a simple reunion. She intends to orchestrate a real-life murder mystery game, and her attention has already turned toward a deeply personal tragedy—the supposed suicide of Ui’s father. Rather than accepting the official conclusion, she harbors dark suspicions about those closest to him, particularly his younger sister, Haruka. Now drawn into her dangerous scheme, Ui finds himself entangled in a high-stakes puzzle where the boundaries between virtual games and reality have vanished, forcing him to confront unsettling questions about his own family.
