In the Purgatory, Godou meets Susanoo, who reveals himself as Ena's guardian, helping Godou understand his past before retirement. Meanwhile, Ena allows her sword to fully control her, draining Erica's energy. Liliana and Yuri witness a black aura covering the world. Godou takes over the fight, causing Ena to retreat. As Erica dies, Godou attempts to teleport her to Earth but lands in various places. At the Kusanagi household, Shizuka misunderstands Athena's comments about her relationship with Godou before Athena leaves. On an island, Godou summons the Youth from Verethragna's spirit, having Erica ingest it to save her life. Liliana and Yuri are interrupted by the scythe-wielding serpent goddess who consumed Perseus.
