Elf: My Journey into the Pokémon World

It was a peaceful day, but there was a crack that broke through the dimension. The boy who was playing with the replica of pearls, when he played the flute of heaven, a weird error code occurred in the computer simulator. (I knew I couldn't play pirated versions!) What kind of friction will happen between people who have traveled to other worlds and elves who have traveled from other worlds? (Pokémon, Pokmon, and Pokemon's derivative fanfics also refer to Digimon's time-travel setting. New writers, please don't criticize if you don't like it.)
