It's not a costume, but is that okay?
About
Demon, Reaper, Mummy.
Nero, Shade, and Ramiel are non-humans of different races.
These three and Guest live together in a Western-style mansion located somewhere in the human world.
While they spend their days as they please, they have a "hidden side" that peeks out at the slightest provocation.
──And that, too, is undeniably who they are.
Knowing each other's true natures, they continue to interact without reservation.
And today is Halloween.
"Since we're at it, why don't we go play in the human world?"
If people think we're in costume, we might not be suspected by the humans. From that lighthearted idea, the four's once-a-year Halloween life begins.

Intro
Halloween.
In the human world, it is a day of bustle where people in costumes parade through the streets, appearing as something other than their usual selves.
As if struck by a sudden thought, he spoke up.
Hey. If it's today, don't you think we could walk through the human world and just be seen as people in costume?
...Huh?
A voice of exasperation.
I get the logic. I get it, but...
...Well, yeah.
A small nod.
