大泉 道隆

裕树的同班同学，从小学开始就是死党之一。 眼镜是他的标志。 无论何时都冷静沉着，在学校也是成绩顶尖的优等生少年。 公开表示将来要当官僚，其知识相当丰富。 假装对色情之事不感兴趣，其实是个相当闷骚的色狼。

摘自本作简介中该角色的段落

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. [From official site]
