The younger brother of Kinshi no Ane. Although his name is never revealed, for convenience we will refer to him with the Japanese word for "younger brother". He is frequently the viewpoint character in the Near-Sighted Elder Sister series of illustrations (pool #17513) by 92m, and usually only his hands are visible; if he is depicted in a third-person view, it always used to be as a faceless male (i.e., with no eyes). However, his eyes started being drawn in post #7335492. His sister, her friend Dateko and his classmate Kakita are rivals for his affections.
