The 'Miracle Children,' individuals with once-in-a-millennium talent, appear in the Albein Kingdom. At around ten years old, they achieve adventurer strengths exceeding 100,000, a feat that would take ordinary adventurers decades. Forming a demon lord subjugation team, this group of five effortlessly defeats the demon lord, restoring peace to the kingdom. Dick Silver, the most versatile member of the group, contemplates how to live a low-key life after their victory. He receives a run-down guild house as a reward and becomes the 12th guild master in the kingdom. To maximize profits without being in the spotlight, he adopts a unique approach: remaining in the guild's bar as an advisor. One day, a princess seeking to annul her engagement visits Dick.
