Kiyomi is a tall, voluptuous girl often wearing a stern expression on her face. She has long black hair going down to her waist and straight-cut bangs across her forehead. Kiyomi is stern and rather haughty, but shows a softer side with many of the people that she cares for. She is also very poor at holding in or hiding her feelings, letting people know exactly what she thinks both physically and verbally (and perhaps a little uncontrollably and excessively) whether she wants to or not. Because of this, her austere disposition is often betrayed and the majority of the cast (except for the hapless Takashi Yura) can tell what is going on in her head after just a few meetings.
