[@Nightraider] I can adress the issue number three right away. It's because he has read a lot of horror fiction since childhood, although I should have written about that more clearly.

Issue number two: He has gone after Croyd for revenge. It's not noble, nor just, but he sees Croyd as a criminal who needs to be apprehended

Issue number one: thanks to your opinions, I think I will change James' nationality to American. Perhaps I will rewrite as a son of a middle class stock broker who lives and studies in New York.

I am going to revise and overhaul the character in the coming days. I think I won't change his Ace talent, but I'll maybe make some adjustments.
