Other Facts
-As Naru would say, Mutumi is the female version of Keitaro. They are so similar they often say and do the same things at the same time.
-Mutsumi kisses people she likes, and it doesn't have to be people she likes, either. She kisses her friends, men, women, etc. She does it mostly as a sign of friendship or respect.
-She gives Naru her first kiss, but it was not meant to be romantic. She kissed her as a sign of apology and to make her understand that she does not think of Keitaro in a romantic way.
-Although Mitsumi is quite intelligent, she is very forgetful and a little airheaded.
