Maintenance mechanic Daniel's ordinary life shatters when mysterious light engulfs him, transporting him to Zenkon—a realm of monsters, magic, and existential dangers. Summoned alongside Rikuto, a Japanese youth, by an ancient divine spell meant to save this world, Daniel discovers a critical problem: he alone possesses no magic or mana, leaving him immune to spellcraft but vulnerable to physical attacks in a world where power flows from arcane forces. Stripped of magical abilities in a land where they define survival, Daniel must weaponize his mechanical expertise and manufacturing knowledge to survive. Meanwhile, Rikuto harnesses his modern understanding of economics and governance to rebuild the Kingdom of Mornistae, ravaged by continental warfare. Together, the magicless mechanic and the knowledge-wielding hero must forge an unprecedented path through Zenkon's treacherous landscape. Yet questions linger: Why did the gods summon these two unlikely champions? What divine wisdom chose to send a hero with magic and a hero without to a world built upon it? As Daniel and Rikuto navigate political upheaval, supernatural threats, and the mysteries of their selection, they discover that Zenkon's salvation may depend on strengths the gods foresaw but the world never expected.
