Ryuu Kusari no Ori -Kokoro no Uchi no “Kokoro”- - Chapter 7.20

A teenager who unexpectedly gets transported to the modern world from ‘the world of the immortals’ . He finds himself in the body of an ordinary guy. He wants to go back to his world and for that, he will have to practice to get stronger and investigate the reason why and how he crossed through to this world.

“Here you go, this is your wage for the week.”After passing over a small pouch, the woman with her legs crossed behind the desk casually made a 'Check' in a notebook and then, without looking up, waved her hand to dismiss him and said:“Remember to file your taxes... Next!”“Wait a minute!”After pouring out the coins from the pouch and looking at the eight large and one small, totaling nine filthy coins in his palm, Leon couldn't help but widen his eyes in shock, almost wanting to pounce on her and fight to the death right there and then.“Damn it! I just repelled the evil god who was trying to erode the world this Tuesday! You bastard even wants to deduct the salary of the savior?”

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!
