Haru no Arashi to Monster

High school freshman Ranko Haruno's sole desire in life is to keep her head down and get by with as little human interaction as possible. It's working well until a random guy is literally hurled into her path (and knocked out when his head hits the wall). The one responsible? A guy she later finds out is her new stepbrother, Kaya Amamine…How exactly is she supposed to live with such a creepy jerk who seemingly has a penchant for violence?!
