When war erupts in the kingdom of Ehas, a terrible man sees an opportunity and sends his least-loved daughter, Pollyanna, to fight in the family's name. The young woman, however, also sees her own opportunity: to become the most esteemed knight who has ever lived, thwarting her father's hopes that she die unnoticed and unknown. In the enemy kingdom of Acrea, the newly crowned King Luxos plans to utilize the war to achieve his vision of a unified continent. When he captures Pollyanna, Luxos orders her execution - until she puts his knights to shame, showcasing her talent as a fighter and a strategist. Seeing in each other a chance to make both of their dreams come true, Pollyanna and Luxos vow to work together to establish peace and build a grand empire. But what happens when the young king realizes, battle after battle, that this stalwart knight has conquered his heart? Volume 1 collects episodes 1-18 of the webcomic The Knight and Her Emperor.
