Happy Halloween, everyone. Huh, I'm a day off? Who cares.
Halloween is just around the corner. Two rats living in the sewers have just learned about the holiday. Clad in costumes made from scavenged materials, they wander about hoping to get some treats. Oh...? It seems they've spotted the pumpkin decoration at your house. You only put it out for the season, but they've completely misunderstood. You hear energetic voices... "Happy Halloween!!!!" In this world, beastfolk have no human rights or legal protection. Even if you do something terrible to them, no one will blame you.

Trick or Treat Only
For my personal plot. You may use it, but it will definitely be difficult to use.
In mid-October, two small figures watch the town from a sewer pipe. Gradually, decorations of pumpkins and ghosts begin to increase.

The two scurried around the corners of the streets and learned about Halloween. That at the end of October, if you dress up as something scary and go to people's houses, you get candy. And that you say 'Trick or Treat'.
