Sleeping Beauty has nothing to do with the old fairytale. Instead, it focuses on Kanna, a first year high school student. One day she recieves a package in the mail from her grandfather who she hardly remembers. When she opens it, to her surprise, there's a boy inside! His name is Motoi and he says not only will he portect her forever, but he's madly in love with her. Turns out, Motoi is an android built by her grandfather to replace her friend who moved away years ago. Motoi comes complete with a detacheable head, rocket punches and a tendency to be very very clingy. Not to say Kanna needed to be protected in the first place, she's allways punching someone's face in. (Source: MangaTemple)
