Idk, but I just noticed Roy's tattoo is a dragon. I always thought it said 108 and never knew why.
Mind = blown, lol wtf, I always thought it was a 108 as well, maybe its a dragon in the shape of 108, maybe the number means something to him and he just wanted it to be a dragon instead of a plain 108.
Also whenever I saw his tattoo it always reminded me of this for some reason, lol.
