In the original series, he looked very similar to Kiyama Hiroto, but his hair color, eye color, and skin tone were darker. Coincidentally, his casual clothes were exactly the same as Kiyama Hiroto's but his jacket was blue in color instead of pale green.

In the timeline of Inazuma Eleven Ares no Tenbin, he has a fair tone skin and a messy, short, seaweed-like gray hair with some bangs tinted white. He has pale red eyes and a blue lightning-shaped tattoo that covers from his left cheek up to his left eyebrow. His casual clothes consists of a striped black shirt, as well as pants and shoes of the same color.
