Momo is a very intelligent, dedicated person who acts as a natural leader. She is generally very level-headed and calm, even in dangerous situations, but she isn't above falling into panic. Despite Momo's serious nature, she can get roped into silly situations with the rest of her class such as cheerleading, although she rarely expresses enthusiasm in doing so. Also, when she shows her excitement (usually towards passing time with her classmates), she becomes quite upbeat and adorably "bouncy", adding a bit of comedy to her character.
