Merry suddenly collapses, so Yumeji takes him home where his friend, Isana Tachibana, and her father help look after her. Merry explains to Yumeji that she had been hunting dream demons, trying to find a way back to the world she came from, only to be met with more questions. Later that night, Merry decides to leave to do things on her own, whilst Yumeji settles his resolve to help her. Meanwhile, a girl named Yumi with dreams of becoming a nurse suddenly ends up in a different dream world with her resident dream demon, Serio. Serio is suddenly killed, which causes Yumi to lose all drive in her goals.
