Continuing from last episode, Reg takes Riko to the hideout of Nanachi, who begins to work on patching up Riko. Reg is introduced to Mitty, a creature living with Nanachi, who reveals themselves and Mitty as Hollows: cave raiders who ascended from the Sixth Layer and lost their humanity as a result of the Curse, though Nanachi deems themselves proof of surviving the Sixth Layer and retaining their humanity. They send Reg off to fetch ingredients to heal Riko (as well as make Nanachi's dinner), and as he is out, Nanachi seems to recognize Lyza's white whistle. After fetching the ingredients, Reg is sent to clean Riko's blood urine stained clothes at a riverbank behind Nanachi's hideout, and there a memory resurfaces of him standing by a gravestone with Lyza's Blaze Reap in the ground. While Riko is left alone, Mitty begins to eye her.
