Kyouko Inaba

The fiery-haired, fiery tempered female of Nuube's class, Kyouko Inaba is the student that trusts and even possibly likes the teacher the most. Her first encounter with him actually occurred several years earlier, when Nube (then a college student) saved Kyōko (then a little girl) from an inari spirit. (though it is suggested they may have met earlier in a past life) She is seen as one of the most caring characters, usually looking after the welfare of Nube and the rest of the class and showing an emotional attachment towards them whenever something happens to one she cares about. But while Kyouko appears cute and innocent at first, she can possess a violent temper that can drive her friends and even her teacher a tad crazy (though it does tone down later on). When Hiroshi joins the class, she can't stand the annoying boy, but slowly does develop hidden romantic feelings towards him as the series goes on. On the other hand, she consistently has a love/hate rivalry with the closest to a best friend that she has, Miki Hosokawa, usually over physical matters such as her flat chest, big butt, and Sailor Moon-esque pigtails. Her name is an homage to the female lead of Dokonjyou Gaeru. (where, not coincidentally, this Kyouko is also in love with a Hiroshi)
