Momo Yaoyorozu is a member of UA High School's Class 1-A. She is the vice representative of the class, and she looks out for her classmates as if they were her younger siblings. She comes from an immensely wealthy family, and such an upbringing taught her to be calm and collected, though she does struggle with insecurity and doubts.

Momo is about 15 years old, though her voice skews a bit older. She has a very poised way of speaking, curtesy of her refined upbringing.
