Kume wants to form a band with the four of them (Kume & Kojima on guitar, Kita on bass, and Tommy on drums) with Tommy's sister on vocals. Kojima is a boy who is popular with the girls, and Kita is a pervert who likes ero videos. Tommy is a quiet, unpredictable boy who has a fascination with watching bugs. Tommy is perhaps the only one out of the four friends who is still a child at heart, and he dislikes the fact that his friends will be growing up and moving onto high school without him.
