Nidhogg

Nidhogg is a Divine Drag-Ride used by Hayes Vi Arcadia.

Appearance
In the light novels, Nidhogg is described as huge and silver in color. In the anime, while it is still predominantly silver, it also has black and glowing red portions.

Armaments
Two-bladed Sword: An enormous sword consisting of a hilt with a blade protruding from each end. Each blade is several times longer than the Blade of a normal Drag-Ride.

Divine Raiment
Astral Line: Astral Line is the ability to cut through space itself. When the user swings Nidhogg's sword, it creates a cut in space that splits anything in the way, regardless of durability. It can even cut through Yggdrasil after the latter has reinforced itself. The resulting cut appears as a wall of light that can block any attack. The user can create multiple cuts at a time to restrict the enemy's movement. However, this Divine Raiment is limited in that it can only create a certain area of cut space at a time. When this limit is reached, the older cuts will disappear on their own.
