Mizuta has light brown hair and dark blue eyes. He is easily recognizable by his braces. Mizuta's hairstyle used to be somewhat similar to Ishigaki's because he admired Ishigaki and wanted to look like him. He also had very crooked teeth at that time. However, at some point after Midousuji entered the club, Mizuta changed his hairstyle and got braces. In year three, his hair grew slightly in volume.
Mizuta has a tendency to imitate the people he looks up to in appearance and mannerisms, and strives to win their recognition. He prides himself on being Midousuji's underling, following every order, and easily believes false praise used to manipulate him because of his desire for recognition. Mizuta also picked up on Midousuji's rude and cruel means of mocking and talking down to other teams.
