Cheerful, and good humoured, Kohran is mechanically inclined and loves to work with the Koubu. She works as the stage manager of the Hanagumi. 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 Ichiro Ogami to test her inventions, with predictably hilarious results. She idolizes the creator of the Koubu, Shinnosuke Yamazaki.
