Yomi is the smart, studious girl of the munch. In many ways, she is both the most mature and the most "normal". She practically grew up with Tomo and has one of those friendships she kust can't get away from, even though Tomo is always getting on her nerves. Yomi's one other pet Peeve is her weight, and she is constantly (unsuccessfully) trying various diets in an attempt to slim down.
