Kotsubo Okuto

Japanese name:

小壷 奥人

Okuto Kotsubo is the physical education teacher at Yokai Academy and a kraken. Mizore once confessed to Kotsubo that she liked him and he tried to take advantage of her, resulting in the latter freezing him. When he returns, Kotsubo effortlessly attempts to pin the injuries of two students on Mizore to have her expelled and tries to kill her when the plan failed. With the help of Moka's blood infusion and the borrowed vampire power, Tsukune soundly defeats him and exposes the truth to the whole school.
