Dadan is a short boy compared to his classmates, Dadan has light chestnut hair, which he wears swept diaginally up to the left, a round nose, tiny circular black eyes and a mouth that rather resembles that of a cat. Dadan appears to have a meek and timid personality, as he is often seen sweating and nervously introduced himself to Class 1-A. While changing in the locker room, he apologized to the boys of 1-A for his classmate Romero Fujimi's behavior and him clashing with Katsuki Bakugo.
