Momo is a very prudent, dedicated person who acts as a natural leader. She is generally level-headed and calm in dangerous situations, but she isn't above falling into a panic. She is very kind and polite, and quite reserved, yet she can be blunt with her comments about people's mistakes and miscalculations, tending to be very direct and wishing to help her peers improve enough to become great heroes. She shows further development as a selfless hero who gets inspiration from others, while also taking the role of a leader in her class thanks to her skills and intelligence. Because of her wealthy upbringing, she has a sensible and respectful attitude towards others, often being put off by discourteous behavior. She typically takes adverse situations in stride, expressing little concern for losing most of her clothing in battle, as she knows how to construct another set, and would have made her costume even more revealing were it not for restrictions on exposed skin in a costume. However, this often makes others think of her as an exhibitionist. Ironically, she is rather innocent and sensitive to vulgarity and rude mannerisms. This innocence shows that she has a somewhat casual, natural, and non-lewd view toward nudity, which explains her lack of modesty in her costume.

Momo lost confidence but later regains it in her quick-thinking, learning that people have different skills and can sometimes complement each other. Even when she is weakened and trapped by her opponents, she doesn't give up and shows the increase of her Quirk output, ultimately defeating her enemies. When she displays excitement towards pass time with her friends or help them, she becomes upbeat and eager. She also tends to accidentally reveal how rich she is, yet most people understand she doesn't do this out of arrogance or malice.

If you could sound similar to her English VA, Colleen Clinkenbeard, that would be great, but it is not required!
