Vritra

Vritra is Jeanne's equivalent to Bayonetta's Kulshedra, Vritra functions exactly the same. Unlike Jeanne's other weapons, Vritra is the only character-specific weapon she has that isn't recolored to red and white, instead of having a hue of teal-blue. The in-game description for Vritra matches Kulshedra's.

In-Game Description
"'A possessed whip, sealing away the soul of the ancient serpentine demon Vritra. Summoning the power of the demon from a portal on the weapon's hilt, it can be used in the same manner as a normal whip.'"
