Overview
Kotaro, Hayato, and Rin are transported seven years into the past, where they encounter Shiori—a woman who, in their original timeline, was executed for a series of teacher murders—now a fugitive suspected of the first killing but insisting on her innocence; divided over whether to trust her, the trio attempts to save Shiratori, the known second victim, yet despite their efforts they fail, while Rin, tasked with watching Shiori, unexpectedly grows closer to her, leaving Shiori’s actions at the time of the murder unclear and the suspicion surrounding her only deepening.
