My Yandere Succubus Daughter is Mommy-Warrior's Natural Enemy - Volume 6 Chapter 25

Shi Yu, an Archaeologist and Mythologist, crossed into a foreign world where Noble Beasts were the mainstream.

The most feared Assassin in the world died because of vengeance.

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!
