Cheerful, and good humoured, Kohran is mechanically inclined and loves to work with the koubu. She works as the stage manager of the Flower Division. A running joke in the series is that Kohran's inventions are rather accident-prone, often backfiring or blowing up in her face. She sometimes uses Ogami as a guinea pig to test her inventions, with predictably hilarious results when the inventions blow up during testing. Despite her cheerful attitude, she also has a serious side regarding her past; a bandit raid killed her parents and was said to be the only survivor during the village fire. She idolizes the creator of the Koubu, Shinnosuke Yamazaki. Her uniform is green.
