Guest Room

Guest Room (客室) is a room located on the 9th Floor of the Great Tomb of Nazarick.

Background
The room is one of many facilities located on the 9th Floor. It serves as a place to lodge temporary guests that come to Nazarick.

Mass for the Dead Arc
In the game, the guest room serves as a temporary home for visitors that were inadvertently brought through the Crack from the summoning experiments conducted in the Throne Room. After the subjects from whatever parallel world arrive and learn of the situation from Momonga and his aides, they are given sanctuary in Nazarick until a way can be found for them to be returned.

Later it served as a dressing room for the newly created idol group LittleMass.

It was used again by Shalltear Bloodfallen, Albedo and Aura Bella Fiora for the site of their tea party. Both Shalltear and Albedo began plotting on winning Momonga's heart in their new "Trial of Love" at the "Nazarick Swimsuit Athletic Meet".

Layout & Features
From a glance, the room contains many furnishings. There is a fireplace and mantle above which hangs the banner of Ainz Ooal Gown. To the left there is a wardrobe, while to the right there are two chests. In the center of the room appears to be two velvet couches and a coffee table between over a green carpet. On the other hand, there is an area that seems to have facilities like a shower and bath as well as beds.
