After an unexpected death, Koizuku and his friends find themselves in a mysterious white room with a beautiful child who introduces himself as God. Without any explanation, they are to be reincarnated into a new world, but there's a catch—they won’t all be human. Drawing cards to determine their new forms, they’re abruptly thrown out of the sky and into a strange, unfamiliar world.

Koizuku wakes up to a shocking discovery, he's staring at his own headless body! But the surprises don’t end there. He soon realizes that this world isn’t like the fantasy games he knows. Instead of epic quests and battles, he finds himself managing a town, dealing with finances, and navigating a world of complex responsibilities he never signed up for.

Now, the adventure of the great Dullahan Koizuku and his motley crew of monster friends has just begun—and it’s nothing like what they expected!
