Plot

A young boy named Kotaro Kawaii made a slime as part of a science experiment which came to life. The slime named Puniru resembled a penguin, and her creator thought that was cute despite him not wanting to admit it. Seven years later, Kotaro is now in his second year of junior high and is having a hard time admitting his feelings for his senior, Mami Kirara. In that time, Puniru gained a new ability to morph herself into a human girl to have her creator notice her cuteness again.
