Mayumi Thyme is a heterochromia-eyed girl in Rin's class who is always looking for news. She has the smallest bust size in the series, a fact often made fun of by Rin and Itsuki. Nonetheless, she takes pride in her small breasts, rationalizing that by being below average they are a rarity sought after by a select group of men. Mayumi is a half demon, that's the reason for the color of her eyes. though she doesn't have the other signs of demons, such as long ears and magical powers.
