He's a character from Jojo's bizarre adventure Phantom Blood. Jonathan is described, mostly by himself and by other people, as a true gentleman. He never acts out of his own self-interest. As a gentleman, Jonathan is also kind and positive. Jonathan has a mindset where he tries to imagine the consequences his actions would have on other people, even if they appear to be enemies. He is gentle and sympathetic, feeling pain even as he vanquishes a zombified policeman.
