Biography
Deathtopia Virtuoso Suicide-Master is a purebred vampire and may be among the oldest vampires known. Arrogant and proud, she insists on her self-created name and has a taste for unusually long names. She has created many vampire minions, including Tropicalesque and KissShot, and once saved Princess Acerola from her curse of beauty.
Story spoilers
Deathtopia originally manifests from hatred directed at a tyrant called the Corpse King and makes his abandoned Corpse Castle her home. In Shinomonogatari Vol. 1, after KissShot leaves, Deathtopia eventually consumes Tropicalesque's remains; she also saves Acerola from her curse and turns her into a vampire. Tropicalesque's lingering will combines with Acerola's dormant curse to produce a vampire-killing virus, which remains dormant for centuries before ultimately infecting Deathtopia. Shinobu removes the virus from her, turning the purebred vampire human, but Deathtopia later dies after contracting Covid as a human.
