Leina Vance leaves the safety of her family's castle and steps into a tradition she never asked for: only the strongest woman can rule the kingdom, and the right to try is decided every four years in the tournament called Queen's Blade. As a novice fighter with royal blood, Leina travels the kingdom testing herself against opponents like Nanael, sent down from Heaven to oversee the contest and fight in it, and Melona, a shape-shifter working for the Swamp Witch, forced to grow stronger with each encounter just to survive the road. This manga adapts the Queen's Blade visual combat books.
