Tetsu Kageyama

He works as the treasurer of the high school student council. Although he often shows hesitation and is reserved, Tetsu is very observant of the things around him and is a kindhearted individual who understands the problems that people have. Within the group, he looks up to Kyosuke and Sai. Sai in particular reached out to Tetsu when he was all alone and thus holds Sai in great respect for befriending him.
