Tensura x Kumo desu ga, nani ka. Crossover.{COMPLETED}

This is a crossover where the protagonists of both worlds meet in a coincidence.

This is a side story from the main book, but it got to long so I made it a book of its own. Please read the main story in order to not get lost in thought to much.
