What happens when you die at the age of 17 in a car accident? If Death happens to owe a favor then apparently you get thrown into a world of souless monsters hellbent on destruction, and you have to stop them. Oh well, at least I get this cool ability to live my life as a game, wait, what do you mean not right away?(Currently Undergoing a Rewrite)

Being Reincarnated is admittedly a better outcome than just dying outright, but when you are reincarnated into a world where Mad Scientists rule the world, and where they aren't exactly 'good' at doing so, well things tend to get crazy, I guess it's a good thing I know this world well.
