Ookami-san to!

"Hey, Grandma. Are all men wolves... really?"

Hinako, who hates men, comes to an all-male school on an isolated island to meet her grandmother. But as soon as she arrives on the island, she is chased by a group of boys for some reason...? Will Hinako be able to survive among the carnivorous boys, including the sadistic Oogami-san and the suspicious Kitsutaka-kun? Let the romantic comedy-style Little Red Riding Hood begin!
