Somewhat of a snob, Momomi feels Spica as being superior to the other schools of Astraea. Being on the student council for Spica, Momomi helps by giving advice to Shion or agreeing with most of what Kaname says and suggests. When Kaname thinks up a plan, she helps her carry out it out, but tries not to get directly involved, watching from the sidelines instead.

In Momomi's personal and sexual relationship with Kaname, she is ironically usually the most aggressive partner.
