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.

Puniru gets moldy and down in the dumps when Runrune starts ignoring her. Later, she’s determined to get Runrune and Alice to be friends again. Next, AI Runrune hits the scene, and Alice and Puniru face off to see which Runrune is better.

Kotaro and the boys go to the beach for a day of fun while Puniru and Kirara-senpai are at the school pool. Later, Kotaro asks Puniru to help him cool off with a special transformation, the gang hits a café, and then it’s time to tackle summer homework.

It’s time for the school festival, but Puniru and Alice get into a fight over Kotaro. Alice tries to win him over with an incredible offer, and Puniru tries to throw the match so he can pursue his dreams.

Kotaro wants to be cool and decides to try his luck with dragons and a rock band. Puniru then lets the cat out of the bag about Kotaro’s feelings for Kirara, which forces him to make a move. Can he get Puniru to help him out?

Al fin llegó la Navidad, pero Kotaro no tiene ningún plan. Debido al temor de quedarse con Puniru, Kotaro se apresura a planear una fiesta en casa, pero las agendas de todos sus amigos están llenas. ¿Podrá Kotaro pasar la Navidad de sus sueños?

Como todo el mundo desea pasar la Navidad con ella, Puniru anuncia que se irá con la persona que le traiga el pastel de Navidad más bonito. ¡Comienza la competencia por preparar lo mejor que cada uno pueda hacer!

Después de que Kotaro gane un sorteo en el que no recuerda haber participado, sus amigos se van de vacaciones a esquiar. Sin darse cuenta, acaban en el complejo Runrune, de Alice. Mientras disfrutan de la nieve y de las aguas termales, Puniru y Kotaro se replantean su relación y Puniru toma una decisión...
