Rifa, a distinguished female swordsman in the Caphile Kingdom, continuously captures the praise of people. Kishis, the leader of the royal bodyguard, doesn't like it. He lost a match against her in the presence of the king, and ever since he has been holding a grudge.

He finally decides to put his revenge plan into action. Taking advantage of her absolute loyal sentiment to the king, he uses a magic on the king to make him give humiliating orders to her!
Her strong resistance becomes weaker and weaker...
