The Gate

The Sheol Gate is located under the Kagutsuchi branch of the NOL. In Calamity Trigger, the Sheol Gate serves as both Hakumen and Nu-13 stages. It also serves as Unlimited Ragna's boss stage in score attack mode, and it serves an important role in Calamity Trigger's True ending.

In Continuum Shift 's story, Hakumen seems to be bound to this area, until Rachel Alucard breaks the binding that was placed by Kokonoe. It also serves as the battle area where Lambda and Arakune are forced to battle an illusion of Nu in their respective storylines.
