First, this isn’t a story about how to seek survival during Doomsday! It’s rather about how to bring about the end of of times, to bring down the curtain on the world. It’s about how to set off a Zombie frenzy, how to lead the Devil into invasion, and how to guide the descent of Zerg! In this game of doom, I’m the source of everything!

Second, I need to thank those brethren who accompanied me until now. My thanks go to the Lich Monarch, Arthas Menethil (game: World of Warcraft), bringer of endless winter and death; to Alex Mercer (game: Prototype), who created life by consuming viruses; to the Worst Spirit Tokisaki Kurumi (Light Novel: Date a Live), controller of time; to the Magus Ascendant Xerath (Game: League of Legends), imprisoned by runes.

Ladies and Gentlemen, lets bring about a carnival of doom!

This legend tells the tale of the protagonist, Kuroki summoned to protect the demon king from the hero.

Kuroki, unbeknownst to him, suddenly came to another world. He was summoned by the demon king, Modes. The territory which the demon king overrules was in the midst of being destroyed because of the hero. He had no choice but to bow before Kuroki.

“Please save us, Savior Dono!”

Kuroki nodded, deciding to save the demon king due to an unexpected turn of event.
