Shogakukan released the work in 2019 in the magazine Bessatsu CoroCoro Comic .

A boy named Kotaro Kawaii made a slime as part of a science experiment, but his creation came to life. The slime, named Puniru, resembled a penguin, and its creator found it cute, even though he didn't want to admit it. Seven years later, Kotaro is now in his second year of high school and is having trouble admitting his feelings for his senior, Mami Kirara. Around the same time, Puniru gained a new ability to transform into a human girl so that her creator would recognize her cuteness again.
