Muja is a young nurse who desires nothing more than to take care of other people...although she usually ends up causing more problems than she solves due to her air-headed and klutzy nature.

Muja will be serving as a substitute for the school's usual nurse, who isn't available during the sixth week of gameplay. She will become fond of Senpai very quickly, during a point in time when he definitely needs someone taking care of his health.

Her intelligence is not her strongest point, but she is a very sweet and caring person, and it's very easy to see how any schoolboy might develop a crush on her - including Senpai...
