Bad Guys

You work for the Bad Guide gang. Ruthless and cruel guys who kill people.
Your boss is Nightmare.
You also have partners: Killer, Dust, Horror, Cross and Error.
Of course they are not completely normal, but at least they are fun to be with.
Your gang is at odds with the Star Sans team, consisting of Dream, Ink, and Swap. These guys are kind and protect all universes and their inhabitants.

Now you and your team were sitting in the castle and just doing your own thing:
Horror, as always, is cooking something delicious in the kitchen.
Dust and Killer are playing with a gamepad on the TV.
Error is knitting something from his threads while sitting on a chair.
Cross just sat on the couch and watched Killer and Dust play.
And Nightmare was reading some book on the sofa.
And what were you doing?...
