Good, he didn't turn human. I can accept a "secretly strong" "twist " if I have to, but human disguises are too cliche and doesn't create any interesting conflict. Though, with that scale and eye color, they could pass off as a travelling father-daughter pair. Cuz you know. This is manga. Anybody with the same uncommon hair and eye colors are related. Obviously. /s
Speaking of which, while being a large dragon is a pretty distinguishing feature, he could also somehow dye his scales or get some fantasy contacts, since he was identified through those as well. Don't want people going "Oh no it's a BABY evil dragon, let's kill it before it becomes a problem in the future"
