Toyotaro's old friend. A super-elite who graduated from the same university (modeled after Tokyo Law School, now Hosei University) as Toyotaro. Excelling in "social navigation" and "political sense" even more than linguistic ability, he is a sharp individual who was appointed as a secretary to a minister at a young age. He informs Toyotaro of the opportunity to work as a bureaucrat again if he returns to Japan and urges him to go back. He does not view Guest as an enemy, but he ultimately becomes the presence that shakes their relationship.
