A young boy that Asuka meets while helping Ryouta teach a preschool class. At first, he resents Asuka, beleiving that a man is not fit to be a preeschool teacher. But after getting to know him better, he considers Asuka his "mommy" and Ryouta his "daddy." His parents are divorced, and he has no mother, so he thinks of female teachers as his mothers. He is especially fond of Ryouta and thinks they are fine with just her and not Asuka.
