This where everything behind the scenes takes place. The live killings, the strategy planning, the division of teams; Sachiko and Sanae did here. The basement looks simple, a few lights set up here and there. A back wall was dedicated to hanging all the weapons available for Kyuuseishu members. The camera they use to record videos sits on a table scattered with blueprints and other utensils and papers. You can also find several miscellaneous items here and there.
