Sakura Haruno had been an odd child. She knew that she was adopted so thank god that saves her from the family drama. But it wasn't really noticeable a she did bear similar physics with her adopted family. She didn't really wondered about her biological family though. She was fine with the Haruno's thank you very much. They had took her from a village near Kirigaruke when a mission gone wrong and she was the only survivor. They said she had been alone, a child crying in a small house. Either her parents left her to die or they died along the way, weird thing is she couldn't remember them so she didn't really care. But she had to wonder what kind of beings are they that she was born with a sharp shark teeth that made children call her a vampire and that she can breathe underwater. Ino theorized they were merpeople once. Naruto said they must've been pirates. And Hinata theorized that her parents were sharks.
