Puniru follows Kotaro to school to give him something he forgot, but they end up getting into a fight; Puniru turns into an idol to get Kotaro to admit she's cute; Kotaro tries to enlist Puniru's help in winning the affections of his crush.

Kotaro asks Puniru to turn into a first-grader and act lost, so he can look good in front of Kirara-senpai, but little does he know Kirara's maternal instincts go into overdrive around children; Puniru later plays a trick using this knowledge.

Kotaro's favourite childhood plushie has a profound effect on Puniru; he wants to go to the Kyuthi Café, where he gets Puniru to pretend to be his girlfriend so he can order a dish meant for couples.

Puniru freely transforms into various cute forms as a slime.

In an attempt to please Alice, Hodai dons a Runrune costume; Nanpa, Puniru and Honechan fight over Robo Runrune; to put some pep back in the exhausted Kirara senpai's step, Puniru and Runrune become cheerleaders.
