Jacques Yvain stands as the visionary founder of Rebuild Corporation and the brilliant mind behind the groundbreaking autonomous machine system, DZ. Alongside his son Derrida, he uncovered a critical and potentially catastrophic flaw buried within the DZ framework, and fought tirelessly to ensure it would be addressed. His relentless pursuit of the truth, however, made him a target of the company's shadowy inner circle. When a calculated conspiracy closed in around him, Jacques chose to place himself in harm's way to shield his son from danger—an act of selfless devotion that ultimately set Derrida on a journey through time and space.
