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!

The second prince has come of age. To celebrate the advent of such an occasion, the search for a suitable bride began. My younger sister was expected to go to the Royal Palace as a candidate. However, despite this, she eloped the day before her departure. I, the older sister she left behind, looked almost exactly like her – so much that we were often mistaken for twins…

One month, right? For just one month, shall I substitute in for my sister?
