A man in his thirties awakened as Sylvia Black, a five-year-old orphan in the world of *Aetherna Chronicles*—a long-running steampunk JRPG he knew inside and out.

Worse, the girl standing beside him was Claire, one of the game’s heroines. In the original story, she was destined to suffer a horrific childhood before meeting a tragic end.

Sylvia’s attempt to change that fate awakened an extraordinary ability: she could turn back time. After being taken into the imperial family and raised among the emperor’s adopted children as a covert operative, she survived every impossible mission by repeating it until she found a path to victory.

Years later, Sylvia entered Rondarium Academy, where the game’s protagonist and his companions were beginning to gather. Her plan was simple: keep the characters she cared about alive, conceal her power, and avoid interfering with the main scenario any more than necessary.

Unfortunately, her repeated successes made her appear to be a cold, all-knowing genius—and Leo’s party was far too diligent to ignore the suspicious girl who always seemed to know what would happen next.
