Fantasyland: My Girlfriend Has Been Beating Slimes for 300 Years

He was supposed to transmigrate with a System, but when he arrived in Gensokyo, he realized the monsters there were far too powerful. A level-one swordsman was completely useless!

As a result, he was still at his starting level ten years later, until a transmigrator from another world spent three hundred years killing slimes and reached the max level. She made a contract with him and gave Asamiya Toki her max-level powers!

Now he had Kazan the Ghost King, Brachium the God of Terror, and Saya the Frost Witch at his side...

And dungeon entrances from other worlds were appearing all around them.

"There is no enemy ahead of us we cannot defeat!"

Of course, my girlfriend is the exception!
