I recommend "The Magical Adventures of the Demon Hunter" to you. It's a light novel and a derivative Doujinshi novel. It tells the story of a transmigrator who transmigrated and caused trouble in the two-dimensional world after obtaining the system and the Spartan bloodline in Devil May Cry. The worlds in the book included Dungeon Quest Encounter, My Hero Academy, Jojo's Wonderful Adventures, Stardust Fighter, Crimson Eye, Marvel Movie Universe, Company of Heroes, Devil May Cry IV, Demon High School, FGO, Fate Stay Night, Fate Zero, Tokyo Foodie, etc. The content was rich and interesting. I hope you like this fairy's recommendation. Muah ~😗
