Some observations:

Northnovas and Elite Ferret was both in their rooms but Lord Winter was out stalking.
It might be as w&f suggested but not necessarily a pro-town role.

We have 3-4 mafia with a "Godfather" included.
there were 3 kills, two by identified beings: a red skinned humanoid and a dark being with fangs and a leopard skin loin cloth; both with some supernatural powers.

The first kill is weird. The lightning striking glass turning it to sand. This is kinda backwards. Is it a clue?
Should we assume we are in Japan (the futon reference in OP) and the creatures are Japanese mythology?

I am thinking 3 kills a night performed by mafia is a bit much. We could face a serial killer or something similar.
