After evolving into a Kijin, Souei shrunk to that of 180 centimeters and with the appearance of a lean young man in his late teens. He looks incredibly calm and collected, which goes well with his confident personality, and is all in all a beautiful man (Ikemen) with a different air around him.

Thanks to Shuna and co., Souei received a brand new attire, matching his dark blue color scheme that isn't too tight nor too fluttering to get caught in sharp objects during his espionage missions. His appearance has stayed the same since, receiving no alterations with later evolutions.
