Bleach: The Template System Chose Me, The Forgotten Kuchiki Novel

Kuchiki Baiyu, the forgotten younger brother of Byakuya Kuchiki, emerges from the Soul Society's shadows after binding himself to a mysterious Template System. Gaining access to the Fujitora Smile Template, he embarks on an unprecedented path as a Shinigami, his power growing exponentially as his synchronization increases, blurring the boundaries between reality and divinity. Baiyu's influence extends across the three realms and beyond—from the Shin'ō Academy to Hueco Mundo's battlefields, through the corrupted Wandenreich, and into the celestial domain of the Soul King. His rising strength captures the attention of legendary figures: Yamamoto Genryūsai recognizes him as the heir to the greatest Shinigami legacy, Aizen Sōsuke seeks to corrupt him into rebellion against heaven, and Yhwach perceives a threat that may rival the Almighty itself. As enemies fear and legends acknowledge his potential, one question remains: will Baiyu reshape the balance of all realms, or become the final blade that destroys the world?
