The World-Crossing Isekai Hunter

Korrin was an average man in all the ways that mattered. He woke up every morning, went through his morning routine, commuted to work, read fanfiction to and from work, and called it a night.

He did not expect to find himself summoned to the position of hunting down unimaginably powerful and cliched villians at the amusement of a bored god, but that's what happened.

Now he has to figure out what he needs to do to survive landing in a new and hostile land, while also finding and ending the horrificly powerful reincarnator.

No problem... right?
