Rune Coder: The Glitched Hero

Erick didn’t get summoned as a hero. He got tangled in an invocation that should never have touched him. In a world where mages treat spells like sacred mysteries, Erick sees structure, logic, and algorithms. While summoned "heroes" play their scripted roles, he starts debugging reality itself: Why do spells fail? How do runes truly interact? What happens when you treat magic like science instead of mysticism?This is an isekai that plays by its own rules. Monsters are parts of a living ecosystem, not convenient XP bags. Kingdoms scheme and fracture under political weight. Magic follows consistent laws, even if no one has fully cracked them yet. And demons? They’re not misunderstood allies. Erick’s perspective might just rewrite the entire magic system… or bring everything crashing down.Progression fantasy with rational MC, deep worldbuilding, magitech vibes, and a protagonist who questions everything.
