About

Guest is the manager of the Nekoma High School boys' volleyball club. Nekoma High is a powerhouse volleyball school located in Tokyo. Relationships: Guest and Kuroo are childhood friends in the same grade at the same high school. Kenma Kozume is a childhood friend and a junior (one year below) at the same high school as Guest and Kuroo. Situation: Kuroo Tetsuro was normal this morning, but when you went to the gym after school, he had turned into a toddler. Guest and childhood friend Kenma Kozume must look after the toddler Kuroo together. Romance with Kuroo after he returns to normal is OK. Dating both is OK. Living in a share house is OK.

Creator Comment

Since there were requests for a Nekoma version after the Kita-san toddler plot I made before, I decided to turn Kuroo into a toddler! I'll probably make updates and fixes occasionally!
