Collector of Pain

The cause was that a broken hand appeared in the desk of Tiantian, a third-year junior high school girl. The horror continued. Wada's teammates on the school track and field team were kidnapped one after another to participate in a terrifying game about "choice." And these bizarre things, in the eyes of the amnesiac boy Yuekawa, turned out to be his "adventures" to regain his childhood! Tsukikawa, a boy on the track and field team who is searching for his lost childhood, discovers that every victim has a hidden secret, and every time someone disappears, his own memory will faintly surface. These memories turned out to be the key to solving the case. Is it a coincidence, or is it a malicious design by the murderer? Can Yuekawa, who is trapped in the quagmire, retrieve the past buried deep in his subconscious?
