Birthday: March 15 Kirie is a classmate of Umaru and Ebina, who sometimes has a scary appearance. She initially follows Umaru home after she finds her student ID. When she encounters Umaru in her "indoor" form, she is led to believe that she is meeting Umaru's little sister Komaru, and finds her so cute that she wants to serve her and call her Master. She also admires Umaru in her perfect form that she considers Ebina-chan a rival.
