Mayumi is a human-devil hybrid who is Kaede and Rin’s classmate. 

A curious person and rushes into anything and often becomes a troublemaker. She always carried a digital camera around to satisfy her curiosity.

She is a pretty and stylish girl; however, she has an inferiority complex related to her chests that are even smaller than Primula's. 

Her grades are so low that she joins supplementary classes regularly, but she is quite knowledgeable about trivial matters. Mayumi is also a skilled negotiator.
