Momo is a very intelligent, dedicated person who acts as a natural leader. She is generally very level-headed and calm even in very dangerous situations, but she isn't above falling into panic. Despite being serious, Momo can get roped into silly situations such as cheerleading, although she rarely expresses enthusiasm in doing so. Also, when she shows her excitement (usually towards passing time with others), Momo becomes quite upbeat and adorably "bouncy", adding a bit of comedy to her character. Momo also tends to accidentally reveal how rich she is, yet most people can understand she doesn't do it out of malice.
