A second-year student at Lime Junior High School. He has been living with Puniru, whom he created by accident when he was a child. He is a twisted boy who really likes cute things but hides it from everyone around him. He is sometimes pushed around by Puniru's freewheeling behavior, and sometimes gets nervous when he sees how much she has grown up...

Seven years ago, Kotarou made a slime that unexpectedly came to life. He named her Puniru, and they’ve been best friends ever since. The two have grown up a lot over the years, and Puniru is now a beautiful, carefree girl who can shapeshift into other cute forms. But with her spontaneous spirit and wild antics, Kotarou can never catch a break!
