Rokudou no Onna-tachi summary: Tousuke Rokudou, a freshman at Aomori High School, endures daily harassment from his delinquent classmates, except for his two misfit friends.

The scroll is believed to drive away danger, and after holding it, Tousuke acquires a mysterious mark on his forehead. Despite his hopes of it freeing him from his oppressors, the bullies persist. However, Tousuke discovers that instead of providing protection, the mark seems to work as a love charm, particularly on Aomori High's tough girls, including Ranna Himawari, who is especially formidable.
