Shirou Yusa is a young man cursed by his own brilliance — a natural-born genius for whom nothing has ever posed a real challenge, leaving him perpetually numb to the world around him. A violent motorcycle accident stripped him of pain, taste, and smell, yet paradoxically awakened extraordinary combat instincts within him. Rather than mourning what was lost, Shirou seized this transformation as a chance to break free from the suffocating déjà vu of his existence. Driven by a desperate hunger for genuine sensation, he willingly plunges into the supernatural conflict surrounding the Longinus Dreizehn Orden, chasing the one thing that can make his blood run hot again.
