Toaru Majutsu no Index: New Testament - Volume 1, Prologue: The People Who Became the Protagonists by Some Kind of Mistake. War?

What do you do when you're a loser who is suddenly called the saviour of the world!? You use it as an opportunity to take charge of your own life while picking up cute girls along the way!

Han Luo is just that kind of person, a perverted loser who is suddenly told he is the saviour of the world.

“what do you mean I'm the only one!? cant you see I'm a loser!?”

“If you want to kill me then you are going to have to work for it! My life isn't that cheap!”

Join Han Luo on his journey through the post-apocalypse!

[P.S. This is tagged Overpowered because I always wanted to create someone unbelievably strong. So Han is going to become one of the damn strongest people on this entire site - not just this story. But a good story needs growth, not just a quick power dump, so he'll be a bit pitiful at first, around chapters 1-15. So please bear with me till he gets back from his first time skip. After then, you'll be in for the ride of your lives]

When the last prodigy level esper on Earth disappeared, Earth was in deep trouble of becoming another species’ colony. The ordinary Han, with his intelligence and hardworking character, was able to make a fortune after “accidentally” stepping into the world of dark net, later purchasing an esper power crystal that brought him the ultimate power that changed the fate of the universe.

Dark net is a subset of the Deep Web that is not only not indexed by traditional search engines, but that also requires special tools like specific proxy or authentication to gain access. Dark net is not restricted by any law or morals, so the dark net market has everything that is prohibited by the law. Drugs, slaves, firearms, uranium, bioweapons, rare animals, human testing, assassination, and the list goes on.
