Kotarou Kawaii

Kotarou Kawaii is a second-year student at Private Lime Middle School and the very creator of the slime known as Punie. During his early childhood, a chance encounter breathed life into the slime, and the two lived together for seven years that followed. On the surface, Kotarou puts on a mature front and insists he has long outgrown playing with slimes, yet deep down he harbors an intense fondness for cute things — a passion he keeps carefully hidden due to events from his past. Faced with Punie, who has transformed into a mischievous young girl, he frequently lets his tsundere side show: quick to complain and quip, but holding her dear to his heart all the same.
