Hagure Seirei I no Shinsatsu Kiroku: Seijo Kishi-dan to Iyashi no Kamiwaza

For Glas, the spirit summoning ceremony was supposed to be the defining moment of his life—the sacred rite that would validate his existence and carve his path forward. Yet when the ritual concluded in abject failure, producing nothing but a so-called "flop," his world crumbled. Stripped of his aspirations and branded with the stain of inadequacy, he resigned himself to a future devoid of purpose, an outcast in a society that venerates spiritual prowess above all else. Just as the weight of his disgrace threatened to consume him, an unexpected royal decree tore him from his obscurity. Summoned to the brutal front lines of a simmering conflict, Glas is assigned an unorthodox role as a war doctor, serving alongside the princess's elite order of knights. Though his summoning was deemed a catastrophe, its residual effect—an inexplicable ability to heal any wound or ailment without fail—proves to be anything but worthless. Thrust into the bloody chaos of battle, this unlikely physician must navigate the brutal realities of warfare, earn the trust of wary comrades, and confront the profound irony that his greatest humiliation has become the very key to survival. Thus begins a stirring fantasy chronicle where a single, despised failure reshapes the fate of a kingdom at war.
