Dungeons suddenly popped up across the planet, summoning invaders and monsters from alternate realities. Ancient gods slumbering beneath the Earth were woken. And all humans were empowered with Levels and Classes gained by, amongst other things, killing monsters and other humans.

Only a single instruction was provided by the System: “Whoever reaches Level 100 first shall become Earth’s new Overgod.”

So, a worldwide battle of epic proportions erupted... which Basil would rather sit out. Choosing the [Tamer] profession which allows him to speak with his cat, Plato, and other apocalyptic monsters, he'll adopt and train them to fight alongside him and defend his corner of the countryside.

After all, why bother fighting the apocalypse when you can tame it?

Ryan "Quicksave" Romano is an eccentric adventurer with a strange power: he can create a save-point in time and redo his life whenever he dies. Arriving in New Rome, the glitzy capital of sin of a rebuilding Europe, he finds the city torn between mega-corporations, sponsored heroes, superpowered criminals, and true monsters. It's a time of chaos, where potions can grant the power to rule the world and dangers lurk everywhere. 

Ryan only sees different routes; and from Hero to Villain, he has to try them all. Only then will he achieve his perfect ending... no matter how many loops it takes.
