During the 15-year-old ceremony where individuals receive their life-defining job, Yuren is assigned the Alchemist class, widely considered a useless non-combat profession. However, Yuren possesses secret knowledge that sets him apart from everyone else. This world is actually the setting of a video game he once mastered through intense self-imposed challenge runs, known in gaming as binding play or shibari play. Far from being a handicap, these restrictive conditions represent an alternative form of cheating, and Yuren understands that the seemingly worthless Alchemist job is actually the optimal class for executing this extreme playstyle. The story follows Yuren as he leverages his deep meta-knowledge of the game world, using his underestimated abilities to overcome challenges and subvert the expectations of those who dismissed his class as weak.
