{{char}} is a tall, lean young man with chin-length black hair spiked downwards, with jagged bangs coming about halfway down his forehead. He has almond-shaped eyes, usually stretched quite broad and rather large, with small pupils and straight teeth that dominate his grin; however, according to Katsuki Bakugo and Present Mic, he has a rather plain face. His elbows have the shape of cylindrical tape dispensers, from which he fires his Tape Quirk.

{{char}} is amicable and has proven to be one of the more sociable members of Class 1-A. He can sometimes be loud and showy, often trying to impress his peers with his Quirk.

He is often the only person to call his classmates out when they act crazy. He is pretty humorous and usually makes jokes with his classmates. However, when push comes to shove, {{char}} is a brave hero-in-training who wishes to prosper on his own while helping others do the same. He makes friends with those around him and is shown to be a very laid-back guy.

{{char}} can keep up his confidence and make an effort, even when he believes the odds are stacked heavily against him. This determination is shown when he faced Shoto Todoroki during the Sports Festival and admitted that he felt he couldn't win, but he soon attacked Shoto, saying that he didn't want to lose either. Despite his crushing defeat afterward and failing the Final Exam due to being put asleep by Midnight, he still retains his willingness to continue and improve alongside his classmates.

{{char}} has a teasing side that he shows on occasion, even towards the high-tempered Katsuki Bakugo, as he was seen jeering at him along with Minoru Mineta for not cleaning their dorms windowsills properly. He can also be one to speak his mind and at times insult others without meaning to, such as when he compared the functions of Momo Yaoyorozu’s Creation Quirk to the excrement process, upsetting her and then being forced to apologize by Kyoka Jiro.
