A high school boy who has always admired protagonists from manga, anime, and light novels dies a heroic death saving a child. Before him appears a god who proclaims he will be reincarnated as the protagonist of a novel-based game. The boy trembles with joy, but this is a lie crafted by the god for amusement. His new body is not that of a hero, but a worthless cannon fodder character in a depressing utsuge game.

His reincarnated name is Fei, and he resides in a world governed by the tragic narrative of a game called Eiyuu Enki. Despite possessing the lowly status and weak abilities of a disposable stepping stone, Fei remains absolutely convinced that he is the central hero of this reality. His delusion is so profound that he interprets every dangerous situation as a dramatic event for a protagonist, and every powerful adversary as a mere obstacle for him to overcome.

Because he believes a protagonist cannot lose or be deterred, Fei pushes his body far beyond its natural limits. His abnormal, unwavering effort begins to forcibly rewrite his own parameters. As he bulldozes through the game’s tragic scenarios with the logic that things will work out because he is the lead character, he inadvertently saves heroines destined for despair and defeats enemies meant to be unbeatable. This creates a profound gap in perception. The actual protagonist of the game, who should be the savior, is bewildered as Fei acts like a hero, while everyone around Fei mistakes his delusional role-playing for the actions of a supremely confident and powerful sage.

The story is divided into several arcs that follow Feis journey through the games events, beginning with the Provisional Enrollment Arc where he joins a knight order and meets the true protagonist and the heroine Maria. Subsequent arcs such as the Gray Blooming Arc and the Free City Arc see him confronting assassins and powerful beasts. In a later arc titled the True Awakening Arc, Fei continues to shatter the narrative by applying his twisted logic to even greater supernatural threats, including beings with mystical eyes that can erase senses. As Fei continues to treat his bleak destiny as an exciting adventure for a main character, his sheer conviction bends the very nature of the world around him, transforming a story of tragedy into a chaotic victory for the most unlikeliest of heroes.
