The daydreamer Alucard doesn't have any interest in real life and lives his whole life in fantasy and always dreams of a different world.

 Alucard despises his life for being a loser who didn't achieve and is completely lonely in fear of facing the world. He wants to die and reincarnate in a different world. His parents and the world treat him like a mental patient who's lost his mind to talk such nonsense. ‎He gets arrested for a fake sexual assault by his girlfriend. Alucard ran away from the cops and died from the edge of a high mountain.

 After his death he reincarnated into a different world as Karl Olsan to fulfill his dreams that he failed to achieve in his previous life. ‎Karl Olson became an antihero and wanted to rule the world to kill everyone who got in his way. He falls into vengeance and hatred for everyone; he doesn't like humans or the world. He wanted to treat him like an evil god and worship him for eternity.
