The manga is an isekai story where the protagonist is reincarnated directly into the world of the classic soccer video game Pro Evolution Soccer, specifically within its beloved Master League mode. Rather than arriving in a generic fantasy world, the main character finds themself on a virtual pitch surrounded by the fictional players that fans of the game will instantly recognize, such as Castolo, Minanda, and Espimas. These are the notoriously low-stat, generic players that players would start with in Master League, making the protagonist’s struggle to improve and lead this underdog team to glory a central focus of the narrative. The series is written by Kiminori Wakasugi, the creator of the comedy manga Detroit Metal City, in collaboration with Konami Digital Entertainment, the original creator of the eFootball and Pro Evolution Soccer franchises. The story capitalizes on the deep sense of nostalgia that long-time fans hold for the PES series, turning the quirks of the older games—such as unlicensed team and player names—into a fully realized world to be explored and conquered. The manga serves as an official and unexpected adaptation of the eFootball video game universe, celebrating the legacy of the franchise through the lens of a new, immersive isekai adventure.
