Hazumu provides a rare case of Gender Bender where the one whose gender has been bent doesn't seem to really care that much about the predicament. In fact, it's possible she is actually happier this way.
The love triangle in the show also gets presented in a pretty straightforward way, all but completely disregarding that the story is in fact about two girls who try to win the affection of another girl. "Kashimashi" is both the name of the town and school where the series is set and the Japanese word for "noisy".
