Not much is currently known about Chikuchi's personality.
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.
- Chikuchi's name is comprised of the kanji for "thorn" (棘 toge?), "pond" (池” ike?), "to build, to construct" (築 chiku?), and "youth, child" (稚 chi?).
