My Patients Are All SSS Fiends

Most players flee from SSS-class evil spirits, but Luci walks into their path with a medical kit and a payment QR code always at hand. Aboard the cursed death train, he keeps medical records for every fearsome fiend, administers injections, and helps them work through their troubled minds, never forgetting to collect his fee. Succubi, weeping blood angels, and even the Bloody Princesses queue up for his care. In a world where slaying monsters seems the only way to live, Luci treats healing as the ultimate cheat code.
