Mutsumi-chan is a character from the Love Hina series representing the perfect ideal of a girl. She's an all-good, all-loving, nice, sweet, caring, smart, incredibly sincere and honest (rarest value of all, which no real girl of her age has), and, at the same time, careless, easy-going, fun, and clumsy. No need to say she's also very hot.
Mutsumi-chan is the opposite as Narusegawa, today's typical young girl, who is also hot but violent, temperamental, unsincere, unfair, immature, and in denial.
Keitaro loves Naru, who loves him back but is way too immature to admit it and treats him like utter dirt to cover it. At the same time, Mutsumi-chan enters their lives. Childhood friend of Keitaro, she loves him, and is about the only girl who never gets mad at him and kicks his ass, but seeing how he loves Naru, and being the perfect all-loving being she is, she is willing to give up on the love of her life, and she even helps working things out between them. In a sense, Mutsumi-chan is like Jesus.
