A dude made a deal with The Devil to bring him to his favorite factional world.But after arriving at this new world,he realized that all the memories of this world is gone.He can't even remember which world he is in now. (Typical Devil business there always a catch) . . . . . . . This is first time I write a novel, fanfic in this context, so there will be lots of mistakes. I will try to improvise as time pass, as I get more experience. Help me to grow as a writer by giving me feedbacks. . . . . DISCLAIMER English is not my first language so there is bound to have grammatical mistakes. It is fan-fic. I don't own any copyrights of pre-existing characters I don't own any copyright of a book cover. It is from ' solo leveling '.
