"Dead Mount Death Play" is a supernatural action anime that blends elements of fantasy, mystery, and dark humor. The narrative centers on a powerful necromancer known as the Corpse God, who is transported from a medieval fantasy world to modern-day Tokyo after a climactic battle with a heroic swordsman. Upon arrival, the Corpse God inhabits the body of a recently deceased young man named Polka Shinoyama, who was murdered under mysterious circumstances. This unexpected reincarnation sets the stage for a complex story of survival, revenge, and supernatural intrigue.

Polka, now sharing his body with the Corpse God, must navigate the unfamiliar modern world while uncovering the truth behind his host’s murder. The Corpse God’s necromantic abilities, including summoning and controlling the dead, become crucial tools in this endeavor.
