Summoned as the Weakest Hero

Yagami Ren learned early that promises are only kept when they're cheap. Poverty taught him that lesson first; a family that fell apart around him confirmed it. By the time he'd absorbed every humiliation the world could offer, he'd already buried the part of himself that expected better. Then the light took him anyway. He wakes up crowned a Hero alongside his entire class — and handed a status window that ranks him dead last. Gravedigger. Rank F. While his classmates draw blades that split mountains, Yagami gets a shovel and a job title built for corpses. The kingdom dresses it up as divine selection. Yagami reads it as a cage with better lighting — one more system built by people who profit when a Rank F hero smiles for the crowd and does exactly what he's told. Underneath the coronation speeches, someone is keeping score. Every ally has an angle he hasn't found yet. Every kindness comes with a bill nobody's shown him. He can spend what little rank he has climbing toward the hero they need him to be. Or he can stop performing gratitude, and find out exactly how far the most expendable man in the kingdom can rise — and who's left standing once he gets there. Yagami spent his old life invisible. In this one, he intends to be impossible to ignore — starting with the kingdom that thinks a Rank F hero is harmless.
