Mitsuki and Takuto, who is disguised as a plushie, go to the studio for a recording session while Meroko stays home pretending to be Mitsuki. Inside the booth, Mitsuki learns the procedures, but a young girl named Nanami sneaks in and takes the sleeping Takuto away. During a break, Mitsuki searches for him using a whistle he provided. Upon finding them, Nanami refuses to return Takuto, lying that she has no parents to justify keeping him. Mitsuki follows Nanami to a store where Nanami claims her parents work. Mitsuki remains skeptical, leading to an intervention by Nanami's actual parents. Finally, Nanami returns Takuto to Mitsuki and becomes Fullmoon's number one fan.
