Takumi Sadohara

Takumi Sadohara was the first homeroom teacher of the Ishiyama class at Saint Ishiyama Academy prior to Saotome Zenjūrō's arrival. Bespectacled, and at first overconfident on his ability to exert control over the thugs, he quickly fails to do so, when his attempts to intimidate them by means of authority, strength or coercion backfire badly. He later becomes attached to the group and supports them in the volleyball match, and is greatly disappointed to be replaced by Saotome.

Abilities
Since he is a teacher, Sadohara shows no physical prowess and no intentions of getting into conflicts. However, in a flashback, he is shown to be the old champion of the Saint Ishiyama arm wrestling tournament earning him his nickname "Gold Arm Sadohara".
