I'm Slaying Demons in Tokyo

That day, without any warning, a huge meteorite fell from the sky. When people thought that Tokyo would be sunk by the meteorite, the meteorite actually turned into a ball of smoke and dispersed, disappearing without a trace. But from that day on, the world began to change, and people with great resentment began to turn into legendary monsters. The evil gods who descended from the sky and the monsters that had been defeated by Abe Seimei, Minamoto Yorimitsu and others, such as Yamata no Orochi, Shuten Doji, Slippery Ghost, Tamamo Mae and other big monsters, also began to lead the monsters in the monster world to make a comeback. Hundreds of ghosts march into the night, and the carnival of monsters begins.
