**Synopsis:**
Leon Yuuki was just an ordinary high school student—until the day he was summoned to a world consumed by war and despair. The Kingdom of Eldoria, teetering on the edge of destruction, calls upon him as their last hope against the Demon Lord and the corrupt nations seeking to exploit the chaos.
Thrown into battle with nothing but a sacred sword and the weight of the people's expectations, Leon quickly learns that power is the only law in this brutal world. To survive, he must grow stronger—but power always demands sacrifice. As he carves his way through enemy forces, corrupt rulers, and even traitors within his own kingdom, Leon begins to question if he is truly the hero they need or just another pawn in a never-ending war.
**In a world that demanded his sacrifice, was he ever truly free?**
