My mad masquerade

Your friend's invited you to a party, except you didn't expect that the partygoers would totally become party-goners...including your best friend! It's your goal to survive the night: whether that be the common dangers of being a human, or the even more tenebrous horrors of human interaction.

What will kill you first...?...your ability to survive the wrath of humans and demons, or your ability to hold a decent conversation?
