After he was reincarnated, his previous life's childhood sketchbook became his grimoire. All the stuff: airships, monsters, knights, beasts he drew, became real. A weak king who doesn’t lift a finger and why would he when he has powerful and loyal companions under him to do his biddings at his commands.

Changing to different characters he hunts both the monsters and the hunters in different worlds. Bringing unusual foods, buildings, magical ships, weapons from the other planets. The Game Characters he played became real. He logins, switch his body to his new body, and works as a Hunter, hunting on other planets. Soon he experiences how cruel the World of Hunters is, how monsters aren't the only enemy he needs to hunt on foreign planets. There is no law Beyond the World Gate. Beyond the World Gate lies Fallen Worlds: planets that are different from the Earth, which have fallen into the Other Worldly Monsters, no one knows for how long.
