Puniru is a Kawaii Slime

Puniru follows Kotaro to school to take 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, Kirara-senpai.

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 favorite plushie as a child was the adorable Kyuthi-chan, which had a profound (jealous) effect on Puniru. Now 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.

Alice, granddaughter to the president of the toy company that made Kyuthi-chan, challenges Puniru to see whether she or a character Alice created is more adorable-and you could say the competition gets blown into gigantic proportions!

In an attempt to please Alice, Hodai dons a Runrune costume. Meanwhile, Nanpa, Puniru, and Hone-chan fight over Robo Runrune. Then, to put some pep back in the exhausted Kirara-senpai’s step, Puniru and Runrune become cheerleaders.
