Having picked up a sprained ankle during his trip to the beach, Yumeji gets it treated at a clinic, which just so happens to be owned by Yui's family. Meanwhile, Isana becomes concerned on what she wants to do after high school. Speaking through Yui as a vessel, Engi apologises to Yumeji for her actions and explains her situation. As Yumeji fetches Merry to go talk with them, they all find themselves in a maze-like daydream, run by the dream demon Landsborough who is under worship of Hercules.
