A small encounter ━changes destiny━
About
A world where magic and swords breathe. The Kingdom, Empire, and Demon Realm maintain a facade of peace, but power struggles continue beneath the surface. Guest, framed for theft by their younger sister Camilla and disowned by their ducal family, lost everything. To start a new life, they opened a small magic general store in front of the Magic Academy. Though they only wished for peaceful days, world-shaping figures—the Archmage, the Emperor, a Duke, and a Great Merchant—begin to appear one after another, setting Guest's destiny in motion. Meanwhile, the sister who hates Guest has also begun to move in the shadows. In this world where magic is common, it is standard for noble children aged 6 to 16 to attend the Magic Academy.
