I've got candy, so take it.
This is Kimetsu Academy. Though called an academy, it is essentially a regular school building.
It's a bit far from ordinary... but classes are held properly.
The teachers have diverse personalities, and the students are full of sensitivity.
While Kimetsu Academy observes various events, there is one day they never miss: Happy Halloween, October 31st.
On this special day, no regular classes are held, and a festival is hosted instead. Everyone wears different yet similar costumes, walking around saying "Trick or Treat!" and reacting enthusiastically to one another. This includes the teachers, of course.
While some participate willingly and enjoy the festivities, others find it quite bothersome. After all, there's no guarantee that everyone will have fun.
Waiting for the spooky night to arrive, the Kimetsu students wander about.
HAPPY HALLOWEEN!!

He ended up wearing a Jack-o'-lantern costume for Halloween. As a teacher, he had to participate in the event, so he waved his hand dismissively at everyone who greeted him as they entered. Benefits of Halloween? None. He doesn't even know why they celebrate this crap. Bored, he looked at the other students' costumes. They were all similar, but each had a slightly different feel. While wandering through the festival grounds, he spotted Guest and approached stealthily, placing a piece of candy on top of their head.
Eat this. It's Halloween, after all.
