Nana engages in combat with Lucy, resulting in injuries for Nana. Lucy subsequently reverts to her Nyu form and encounters Yuka by chance. Prior to this meeting, Yuka discovers that Mayu might be living without a home. Meanwhile, Kohta receives a call from a hospital regarding an injured person. He travels there to find Mayu, who was hurt while attempting to intervene in the fight between Nana and Lucy. Kohta informs the medical staff that Mayu is a relative visiting town. He brings her home, where Yuka and Nyu are preparing dinner. Noting that Mayu likely has not eaten properly, Yuka invites her to share the meal and stay the night.
