Vritra hails from the village of Kunlun, renowned for its extraordinarily powerful inhabitants and proximity to the Last Dungeon. As a divine beast, he manifests as a massive red serpent embodying immense power inherent to his kind. His existence is deeply intertwined with the supernatural elements of Kunlun, reflecting the village's ancient connections. He serves as the source of Alka's formidable magical abilities, establishing a significant bond that underscores his foundational role within Kunlun's mystical ecosystem. This relationship involves layers of mutual dependence and unelaborated history.

A critical legacy stems from his physical essence: Vritra's skin was crafted into Selen Hemein's cursed belt, which grants immunity to all evil influences. Initially perceived as a curse due to its unremovable nature and social stigma, the belt's true protective power originates from Vritra's divine nature. Lloyd Belladonna's intervention breaks the curse, freeing Selen and revealing the belt's purpose, indirectly highlighting Vritra's enduring influence beyond his immediate presence.

Classified among Kunlun's powerful divine beasts, Vritra contributes to the village's defiance of common sense regarding strength. His power sets an extraordinary benchmark that shapes the perceptions and capabilities of Kunlun's inhabitants, including Lloyd Belladonna.
