A girl named Shirona, who was picked up and brought up in a remote village. Her brother, Chris, is stronger than anyone else and has an extremely beautiful visual appearance, but she has the biggest drawback that she doesn't have any interest or interest in anything other than her sister. He was chosen by an oracle as 『 Braver 』, the leader of the subjugation of the Evil King, so it's a big deal. There is no way that he will go on a trip away from her sister, and even Shirona, who has nothing to do with her, will join the subjugation party. Along the way, there is jealousy from a saint who is in love with Chris, and there is love for a prince who joined as a knight! After hearing Chris casually say, "Even if it's not my brother or sister, I want to be with Shirona forever," she gradually became conscious of him.
