ちっちゃくないもんっ！～スクールバスでおむかえちゅっちゅ♥～

On the orders of his grandmother Kikuchiyo, Hajime worked as the janitor at a depopulated school on the remote Southern island of Makishima. Not only was he the school bus driver for the cute and petite students, but he was also entrusted as the manager of the girls’ dormitory. Every day he is tormented as he endures their innocent charms.

One day, a part-time teacher arrived at the school and he was tasked with supporting her in her new post. Nono was exceptionally gifted, having skipped many grades and becoming a teacher, even though she was the same size as the students in her class. Under the guise of a silly sex education lesson, the students began to be conscious of him as a man. Will he be able to hold it together?
