Puniru is a Kawaii Slime

Kotaro is an ordinary young boy who, like many children his age, has fallen for the latest slime-playing fad. One day, his slime unexpectedly transforms into an adorable girl, whom he names Puniru. Though undeniably cute, her stubborn personality and constant craving for attention quickly wear on his nerves—it is almost like having a clingy little sister made of goo. Just as the two settle into their strange new daily life, the granddaughter of Kyuthi Land's founder arrives. Can Okanega Alice and her tiny companion Runrune possibly out-charm the world's cutest slime girl?
