Ai feels troubled when Rika continues to insert herself in her personal life, but after falling asleep next to her, she is drawn into Rika's Egg World. The two of them are tasked to protect Miko and Mako, two fangirls who committed suicide to follow after their favorite singer, Yu-Yu. During this time, Ai learns that Rika wants to save Chiemi, one of her fans, after the latter had starved herself to death when Rika tried to get her to stop shoplifting.
