Synopsis: Haru No Arashi To Monster

春の嵐とモンスター / Spring Storm and Monster / 春日暴风雨和怪兽 / Bão xuân và Quái vật High school freshman Ranko's sole desire in life is to keep her head down and just 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 responsible party? 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?!
