My Overpowered Yandere Friend is The Hero of This World?!

(Y/N) (L/N) is a (Japanese) third-year highschool student that was very known for being average in everything he does. He has an average amount of friends, average grades, hell, average-sized house! One day though, while he was dreaming, he met a beautiful blonde elf that was holding a bow, asking him if he wanted to come to another world. Thinking of it as a joke, the boy agreed to see just for the heck of it. One thing though, he was actually transported, and with his obsessive and *slightly* crazy friend as well! How the hell will (Y/N) survive this fantasy land with such a girl on his tail!?
