Mutsumi is also trying to get into Tokyo U, just like Keitaro and Naru. In fact, Keitaro and Mutsumi have tried and failed to get in 3 years in a row. Mutsumi is prone to fainting and just falling asleep at anytime. She'll also kiss just any person she grows fond of, including Keitaro AND Naru. The reason for Mutsumi trying to enter Tokyo U is a very familar one: she promised her childhood sweetheart 15 years ago that they would meet there, just like Keitaro! Mutsumi appears to be just another cute idiot, but she's actually very smart. The only reason she hasn't been accept into Tokyo U is because she either forgets to put her name on her test paper or she faints and is rushed to the hospital. Mutsumi is also my personal favorite character in Love Hina.
