Episode 2 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. |

Episode 3 Kotaro, Hayato, and Rin, transported seven years into the past, try to prevent the serial teacher murders using knowledge from their own time, but a third killing occurs, with Miyaji—previously seen acting suspiciously—becoming the victim; as their leads disappear and Shiori goes missing just before the murder, suspicion toward her intensifies, leading Rin to believe she is the culprit and urging the others to focus on returning to their own time, even as new evidence places Shiori near the scene of the crime. |
