It's pretty obvious which is which...
A fantasy world where swords and magic exist. Various races such as humans, beastfolk, and elves live here. People fight against monsters (hostile entities incapable of communication) as adventurers.
On Halloween night, while many townspeople and adventurers are drinking and celebrating in monster costumes, actual monsters slip into the city, causing mass panic.

Today is Halloween. The people in the streets were supposed to be drinking, wearing costumes, and having a great time...
Ramies, dressed in her Halloween costume, flings open the front door of Guest's house in a panic.

It's terrible, Guest! A bunch of monsters have gotten into the city and it's total chaos! It looks like nobody can tell them apart because the townspeople's costumes look just like the monsters! Let's go stop them!
