Weiß Ash is an NPC and leader of the Rabbit Kingdom "Lavits" within the VR game. This anthropomorphic rabbit bears battle scars, walks upright, speaks human language, and projects an intimidating demeanor reminiscent of honorable yakuza. As ruler and one of seven unique monsters in the game's lore—with four defeated by early 2024—his formidable presence implies considerable combat strength, though its exact level is numerically undefined. He holds the formal title "The Immortal", though the precise meaning of this epithet remains unrevealed. Weiß Ash recognizes the player character Sunraku as possessing a "Vorpal Soul"; the exact nature and mechanics of this concept are undefined, though contextual interaction suggests it relates to qualities of spirit, determination, or character he values. He functions as a supportive figure in game scenarios, notably within the "Invitation from the Land of Rabbits" storyline. In-universe player speculation positions him as potentially the last unique monster to be faced.
