Tejima

A physical education teacher. He tries to drive away the "them" that appeared at the school gate, but ends up being bitten and turns into one of "them" himself. Incidentally, he is also the first person in the story to turn into one of "them." He had feelings for his colleague Hayashi, but ironically, he ends up turning her into one of "them" with his own hands while trying to protect her from injury.
