Happy Seven

A girl named Amano Sakogami experiences an excessive amount of misfortune. After accidentally entering the Better Fortune Research Organization's clubroom, she meets a boy and seven girls who wield the powers of luck deities to combat the Magatsugami—creatures that influence people's luck and well-being. Amano becomes the club's manager and later joins their efforts to fight the Magatsugami and their leader, Kukitomoe.
