Wim gets abandoned by his party for doing the exact job support magic is supposed to do, then realizes he's been playing the game wrong the entire time. The show doesn't waste time on moping, it pivots straight into the visceral satisfaction of a support caster discovering that buffing himself is a completely different animal than buffing others. Every power spike lands because you've watched him get disrespected for the thing that's about to make him untouchable.
Wim's gift lets him amplify his allies' power through magic, but in a world obsessed with flashy combat prowess, support casters are treated as expendable. When his party dumps him without a second thought, Wim faces the harsh truth: nobody wants a mage who can't fight. His only lifeline comes through Heidemarie, his childhood friend, who secures him a trial with Nachtlibelle, one of the kingdom's most elite adventuring squads. They're skeptical at first, but Wim carries something his previous teammates never bothered to notice: his magic isn't limited to making others stronger. It's far more versatile and powerful than anyone assumes. What begins as a desperate shot at redemption becomes Wim's chance to completely redefine what support magic means. He'll prove that standing at the front lines isn't the only way to change a battle's outcome, and that the most underestimated person in the party might be the most essential.
