Yamano Katsunori shares a tale of a woman cursed after her husband’s murder by the village head’s son, leading to family deaths and the appearance of Undying Butterflies. Luminous butterflies later guide villagers to Tateha’s body. Hajime questions Miyama Hikage about his identity, noting his butterfly-related name and a burn mark from an incident in Kanazawa six months prior. Suspicions arise regarding Eiji Touno and events from twenty-five years ago involving Shimon and Minoru Suga. The investigation intensifies when Ageha is attacked by venomous spiders in the balneary, linking current deaths to past tragedies.
