This is what happens when a 21st Century assassin tries to retire, and a country gets power hungry and takes over the world. My name is Marethyu, a highly trained assassin from the Underworld; a guild of assassins that is renown throughout the world for their brutality and efficiency. The one problem is I retried, well tried to at least. Having dormant nanobots in your body is a weird. But enough of that, being the highly capable and trained killer that I am coupled with the fact that old habits die hard, I was found out by my former guild. Now I have a world to save.
