大泉 道隆

Yuuki's classmate and one of his best friends since elementary school. His trademark look is his glasses.

He is always calm and collected, and is a brilliant boy who boasts having one of the highest grades in the school. He has declared that he will eventually become a bureaucrat, and his knowledge is quite impressive.

He pretends to be uninterested in sex, but in fact, he is quite pervertred.
