Rokudo's Bad Girls

Tousuke Rokudou attends Aomori High, a school with a reputation for being rough on its students. Despite the bullying he faces from his classmates, he has managed to form close bonds with two friends who also struggle to fit in. When Tousuke's late grandfather leaves him a family heirloom - a scroll said to have protective powers - he thinks it might finally give him the courage to stand up for himself and his friends. However, the scroll's effects are more complicated than he anticipated, as he discovers a mysterious mark on his forehead that unexpectedly attracts the attention of the school's toughest delinquent girls.
