S1, E6: Merry and Yumeji manage to drive off Engi ThreePiece, but their victory comes at a price when Yumeji is severely wounded. Still, once they return to the Real World, Yumeji appears to fine physically, but he doesn’t seem to do anything but sleep. And while he’s sleeping he has another encounter with John Doe. However, this encounter is much more peaceful than the last. John Doe not only has his cat nurses heal Yumeji’s psychic wounds, he tells Yumeji what he knows of Pharos Heracles. He also mentions another powerful Dream Demon by the name of Mistltein, the Ocean of Trees, and tells Yumeji to be careful, that his wounds at the hands of Engi ThreePiece are nothing compared to what lies ahead.
