Demon Slayer: the Transformation of the Demon Slayer Corps

Introduction to the novel: Ubuya Shiki Teru, with the memory of modern management, became a member of the Demon Slayer Corps. While others were sharpening their blades, he laid out his charts—using data to measure casualties and using processes to reshape the millennium battlefield. Between Tomioka Giyu's silence, Purgatory Anjurou's flames, and Butterfly Ninja's medicine, he weaved a web called "Tianshu". Without wielding a sword, it will change the fate of countless people who wield the sword. This is a revolution about the system: On the thin ice of personal bravery, can he build a beacon that keeps more flames burning?
