His name is Demonslayer, part 4
The forces of evil have flooded the city with cheap, hard and deadly drug, called "The Gates of Hell". After taking the pill one's consciousness is transferred into the underworld, where he or she is offered to exchange their soul for unlimited power, wealth, and attractiveness. Tempted by the generous offer, people agree to the exchange, unaware of the fact that they can die! Survivors are not in luck either: they turn into mindless and aggressive zombies, ready to tear everyone apart for the next dose. Reaping in the name of good has begun!
