High school student Yusuke Saito vanished for six months under mysterious circumstances. When he reemerged, he possessed zero recollection of his prior existence. Now polite, quiet, and striving to live an honorable life alongside his close friend Nanami Shirai, Yusuke believes he is simply an ordinary teenager reconstructing fractured memories. That fragile illusion shatters when an unfamiliar youth confronts him on the street, accusing Yusuke of committing unmentionable acts of torment during his middle school days.

Yusuke soon discovers a terrifying truth: before his amnesia, he stood as the undisputed ringleader of a ruthless group of adolescent delinquents. He inflicted psychological torture, extortion, and physical agony on his peers, earning the moniker of a merciless demon. The victims he discarded have spent years festering in trauma and planning retribution. As former targets track him down to exact revenge, Yusuke must confront a severe philosophical crisis: can a man atone for horrific atrocities when his current self has no memory of ever committing them?

What to Expect

Takashi Sano structures the narrative around escalating tension and moral ambiguity rather than standard supernatural combat. The narrative progresses through episodic encounters with distinct victims from Yusuke's past, evolving into an overarching criminal investigation into what caused his original disappearance and memory wipe. Instead of relying on brute force or power systems, confrontations turn on psychological pressure, blackmail, desperate physical skirmishes, and raw survivor trauma. Pacing remains brisk across the 14-volume run, punctuated by sudden shifts into grim reality that force readers to question who deserves redemption.

Who Will Enjoy This
