Kirie is a girl attending school with Umaru with long navy blue hair tied into a ponytail with a few strands poking out. She has dark blue eyes that matches her hair color. She wears her school uniform normally with her shirt tucked into her skirt and a red ribbon that matches her skirt. She also wears dark brown stockings with a pair of normal black school shoes.
Despite Kirie sometimes having a scary and creepy appearance, she is actually quite shy to the point that she can only talk to children. She calls Umaru's indoor mode (Komaru) "Master/Mistress" and is in service to her. She appears to be quite affectionate and loving toward Umaru and 'Komaru' (the former implying she is a lesbian), however, she is often volatile towards her brother Takeshi Motoba.
