For example, a youth diary like this: ~When I, an otaku, scolded a yankee girl, she started following me around~

Iirino Atsushi is a high school student who is universally recognized as an otaku. While he's average at both academics and sports, he surprisingly possesses exceptional fighting skills. Called out by his bad influence friend Odaka Mamoru, he witnesses his classmate Sukegawa Ryoji being surrounded and stripped naked by Kito Mari and her cronies in a park. Iirino jumps in to help the half-naked Suke and ends up facing off against Kito Mari—but for some reason, this girl then begins clinging to Iirino. An unusual boy-meets-girl story. An unexpected cohabitation with a yankee girl!? Will this self-proclaimed ordinary boy, who is definitely not a delinquent, ever regain his peaceful otaku lifestyle—?
