+Yomi-san!+
Sou ka...
Name: Koyomi Mizuhara
Better known as: Yomi
Yomi is the most well-adjusted of the girls, but that isn't saying too much. She plays the straight (wo)man to Tomo-chan, keeping her in a mild form of check. Tomo and Yomi have been friends since grade school, so their friendship can take a lot of abuse, which it does. All the time. Yomi is intelligent, coordinated, and level-headed. She angers easily, and she is very sarcastic, especially to Tomo-chan. She generally gets on very well with everybody else, but she can be a little devious and will sometimes play a practical joke. Her main target remains her childhood friend, though.
Yomi-san believes herself to have a weight problem and is obsessed with dieting. She is sensitive about the subject, so, naturally, Tomo-chan teases her all the time about it. She seems more want to dish it out than take it, but, considering her position, it's hard to blame her.
Yomi is the most likely of the girls to grow up and live a normal life, but she also wants to have fun (and does!). She truly enjoys her friends, even if she is telling them to shut up half the time. She is a likeable person and is definitely liked by all the girls.
Yomi-san's closest friend among the girls is Tomo-chan, though that's similar to saying that a cat's closest friend is the fly buzzing around its head.
