Jingai Kyoushitsu no Ningengirai Kyoushi Episode 13 English Dubbed

After a traumatic incident ends his teaching career, Rei Hitoma is certain he hates humans. Yet when he sees a job for “a teacher who truly cares for their students,” he’s compelled to apply. Before he knows it, he’s hired—only to find out his students are demi-humans. What begins as a job becomes a journey for healing for both a teacher who’s lost faith in humanity and students who dream of it.
