Masao Hayashida was the teacher of Third Year Class 3-B. He was murdered by Sakamochi's soldiers when he resisted the fact that his students were to enter the program.

Hayashida's corpse was kept in a body bag and allowed to decay to such an extent it was almost unrecognizable and gave off a foul odor.

Sakamochi then revealed his corpse in a body bag to the horrified class when they were on Okashima Island which greatly terrified the students and caused some to even vomit.
