The novel's perfect "Extra"

Upon awakening, Ayanokouji Kiyotaka found himself immersed in a world that seemed familiar, but in a strange body, so similar and yet so different from his old self.

This universe was a unique creation, a testimony to the imagination of a single author, woven into a novel that he devoured avidly. A story where the characters never reached a definitive outcome, trapped in an eternal limbo of possibilities.

The only compass he has to escape this labyrinth is to remain faithful to the main narrative, using his knowledge of the future with dexterity and precision.

However, he soon realizes that this world is not unfolding exactly as he read it. The rules have changed, the lines of fate have been blurred, and now his strategy must adapt to a new game, where the pieces move with surprising intensity and unpredictability.

Against this backdrop of uncertainty and mystery, Ayanokouji finds himself entangled in a web of secrets and challenges, where every step could mean the difference between victory and doom.
