Chikuchi is a young woman of an average build with dark hair. She has ear-length bangs are arched slightly up before they come down, which is styled into a set of low, curved pigtails. She has thin, stern-looking eyes with notable lower eyelashes, and usually wears a sullen expression.
During school hours, she wears the standard U.A. uniform.
Not much is currently known about Chikuchi's personality at present, aside from the fact that she appears to be jealous of and have a dislike for Class 1-A due to their popularity, which she and many other support course students think is baseless. However, after watching their performance during the School Festival, she showed remorse at her previous low opinion of the class and her wish that they perform badly, and admitted to them that their event was amazing.
Chikuchi was having a talk with Tsutsutaka Agoyamato, one of her fellow General Department students, where they criticized Class 1-A and their decision to hold a live show to lift the rest of the school's spirits. Katsuki Bakugo overheard this exchange and the students shot him dirty looks, enraging him. This played a part in Katsuki wanting to make 1-A's performance a resounding success so as to silence their critics.
Afterwards, she and Tsutsutaka apologized for wanting them to suffer misfortune, as Katsuki was pleased by this exchange.
