Shigeo Mizuki has a cartoonish look with a round face, flat nose, wide eyes, and side-swept hair. He has a lean, muscular build. In the SIDE-B Program, he wears a white tracksuit with black stripes. Personality: From what has been seen of Shigeo, he appears to be a fairly direct and blunt individual, stating that he chose Nagi as his partner simply because he had ability and looked like he had guts, and describing his own strength in a straightforward way as running. He also shows a solid understanding of the game, explaining his plan and how to secure a chance during the Bird Cage game. During the same match, he demonstrates strong persistence, managing to clear the ball even while being pressured by multiple opponents. He also comes across as honest in his evaluations of others, responding to Nagi’s comment about people shining by saying that he “just saw it,” while giving a thumbs up. Additional: He's cool. He's really, really fast.
