About a century ago, “Divine Tribulation” invaded reality, unleashing countless demons, monsters, and magical beasts. Humanity was forced into a survival system of “Awakening → Class Advancement → Killing Monsters and Leveling Up.” Death has no universal resurrection system. Only a very small number of healing-class specialists possess the limited ability to keep people alive on the battlefield. The calamity also progresses alongside the release of “expansions.” The preview for the third expansion announces that, ten years later, [Demon God Revival] will arrive. The strongest warriors are ranked by the number of times they have advanced their classes, while the highest-level guardians are known as “Celestial Venerables.” Yet humanity as a whole still suffers from a severe shortage of high-level experts.
Galahad is an elite mage serving in the Intelligence Bureau. For political reasons, he is practically sold off to become the live-in son-in-law of the Northern Grand Duke. The ice-cold Grand Duke’s daughter is actually the “key to defeating the Demon King and saving the world.” Determined to win her heart, Galahad approaches her the only way he knows how—with his usual logic-defying madness and unstoppable drive. There’s just one problem: she’s a Swordmaster who burns mana. For a mage like Galahad, even holding her hand means enduring excruciating pain that shoots through his entire body... “I want to touch her again. Next time, for a little longer—.”
