Rokudou no Onna-tachi EP1 - Enjoying Our Time at School in Peace

Rokudo Tosuke is an earnest, mild-mannered student attending Amori High School, which happens to be populated primarily by thugs, delinquents, bullies, and roughnecks of all types. But when a package from Rokudo's departed grandpa promises him protection from incoming danger, he finds himself gifted with something he has no idea what to do with: the affection of every bad girl he comes across!
