Sadohara, Takumi

佐渡原巧

He was the initial homeroom teacher for the Ishiyama class at St. Ishiyama before Saotome arrived. Wearing glasses and initially overconfident in his capacity to control the delinquents, he quickly fails when his attempts to intimidate them through authority, strength, or coercion backfire badly. He later grows attached to the group and supports them during the volleyball match, feeling greatly disappointed upon being replaced by Saotome.
