Mayoi is a very shy and reserved individual, and will avoid direct contact with others as much as possible, or run and hide when suddenly approached. He is particularly bad with large crowds of people, often completely shutting down or becoming ill when confronted with them. Because of this, he tends to observe others from the shadows, hiding from view, observing those who live normal lives. This is due to the fact that he is used to living an extremely solitary life, being shunned by society for significant periods of time.
Mayoya has long, messy, dark purple hair that he usually wears in a braid that hangs down past his right shoulder. The end of the braid is tied with a sleek black ribbon. The hair that is not braided curves around his head, including a long ahoge on top of his head and a longer strip of hair on his left shoulder that almost matches the length of the braid. He has light turquoise eyes, sharp, shark-like teeth, and a mole under his lip. He is described as having "handsome features."
He is 18 years old. His height is 174 centimeters and his weight is 54 kilograms.
