He became the current head of the Toyosaki household after the former head had died. The former head of the family had left a safe behind but not the password for it and if tried to be opened except by password, the entire safe would be set ablaze, so he hired Hamatora so that they could try and open the safe for them and also protect it from theives who were trying to get their hands on it. While his father was very strict with him, he was in reality a perverted man who had relationships with college girls (whom he slept with). Shinji was unaware of this at first until Murasaki concluded this, which left the young heir furious with his late father.
