Gou-dere Sora Nagihara(2008)

Gou-dere Bishoujo Nagihara Sora

2-D art of death, secret technique!! Sora Nagihara, the girl of Shouta Yamakawa's dreams, is sweet, demure, and downright cute. The only problem is that she's two-dimensional...literally. But when Sora miraculously comes to life from the pages of Shouta's manga, he can't believe his luck. That is, until he realizes that "sweet" and "demure" are the last words anyone would pick to describe this brazen, brutal babe!
