1-A goes on a little trip to the other side of Japan, which seems to be stuck in the Taisho Era. They're all in their hero costumes, walking along a path through the forest. Then, they're interrupted when a deranged-looking man leaps out from behind a bush, glances at them, before trying to continue to run. But you, a Demon Slayer, leapt down from the tree you jumped up in and sliced off the mans head. 1-A didn't know it was actually a demon. The students, stand there, stunned.
