Shinobu is a recurring character in the No More Heroes series. In the first game, she was the 8th ranked assassin and a high school student that studied in Santa Destroy Highschool. She seemed to bear a grudge against Travis believing that he was the one who killed her father because her father was killed with a beam katana. In the end of their duel, Travis wins by cutting off her right arm and spares her in the duel, saying that he would never kill his "Master" and that they never met (Travis watched all the Training VHS tapes of her father until the tapes all wore out). She also later appeared to save Travis from being killed by Jeane.
