Are we sure that Shigure has a fixed hair color like it says in the trivia?
His hair color in his portrait is light blue but it's clearly a dark grey in the my room image we have, so is that bit of trivia wrong?
Actually, the hair on that model is wrong. Shigure definately has Azura's hair colour in game, no matter who the father is. I've found a my room model for him with the correct hair colour, so I'll upload it shortly.
