Puniru is a Kawaii Slime Season 2

Kotaro Kawaii once made a slime as a childish experiment, and the blob unexpectedly came to life as Puniru. Now Kotaro is in middle school and tries to act cool, especially around the older girl he secretly likes, but Puniru refuses to be ignored. She can morph into a cute human girl and keeps changing her look and approach to make Kotaro admit she matters. Kotaro wants ordinary school days, while Puniru turns every small moment into a loud contest of attention and embarrassment. Friends and classmates get pulled into the chaos as Puniru challenges rivals, follows Kotaro everywhere, and tries to prove her «cuteness» in public. Between crushes, misunderstandings, and constant one upping, their strange friendship keeps evolving into something neither of them can easily define or abandon. Puniru treats cuteness like a weapon, switching styles and personas on the fly, and Kotaro keeps getting cornered into reacting in front of classmates who notice more than he wants.
