The antithesis to the "dumb blonde" stereotype, Urumi Kanzaki is a prodigy with an IQ over 200. She is also a heterochromatic, possessing different colored eyes: one brown and one blue. However, she is psychologically disturbed, having her fair share of hate toward teachers. Her genius is displayed repeatedly by such abstract actions as the detonation of time bombs (i.e. firecrackers in disposable boxes) and making a harmless snake look like a cobra using paper cutouts. Her intellect is also shown through actions, such as shouting curse words in French and being able to speak fluent Mandarin. On the trip in Okinawa, Toshito Kikuchi noted that she can speak 5 languages, but ironically, she doesn't understand what her Gundam otaku roommates say.
