Merely a flashback episode that revealed Ayane as the culprit for the Ayanagi City disaster when she confronted Ryo and his parents before she summoned her persona. Shin and Ryo had earlier summoned their personas in their youth when Ayane's persona killed them, which caused Shin to suppress his memories of the disaster. The whale feathers were then dispersed throughout the city when Shin's Persona killed Ayane's. Back in the present time, Kanaru had been buried alongside the other civilians who were killed 10 years ago.
