Hitsugi is a 11-year old girl who transferred from the elementary division of the school for her being a mathematics and science prodigy. However, she is not very good at subjects that requires memorization. She is very vulnerable to jokes, even the most boring ones. Her favorite snack is Yōkan. She refers to herself with the masculine pronoun boku (僕, boku?), an unusual occurrence among females.

On their first day of high school shy Ayumi Nonomura and taciturn Tatsuki Iizuka become lost on the immense campus of Kamizono Academy. An irresistible force of nature named Torako Kageyama accompanied by her best friend Suzume Saotome appears in front of them. Led, sometimes pushed, by Torako, the girls and their classmates work through problems of school, home and adolescence.
