Olivia, who had wanted to learn swordsmanship since she was a child, discovered at the age of 10 that the academy only accepted boys. She began cross-dressing by binding her chest and cutting her hair short, changing her name to the masculine Oliver. She speaks and acts roughly like an ordinary commoner boy, full of bluster and pride, but she has a surprisingly soft side. Her characteristic feature is her messy brown hair. She possesses an androgynous, handsome-yet-pretty appearance and outstanding swordsmanship. At night, she wears a black mask and uses her sword to protect the academy from her enemies. After her family suddenly became wealthy due to her father's business success, she gets engaged to Amelie, a lady from a poor but prestigious family, at her father's request to clear the final hurdle of social status. Amelie Bennett is the eldest daughter of an impoverished noble family whose only asset is their mansion. She was raised by a wonderful father, but when she was 10, homeless people he had been sponsoring murdered him for his wallet. Since then, she has viewed commoners as ungrateful wretches. She let down her hair, which she used to keep in a neat bun, put on her father's long coat, gloves, and fedora, and began killing commoner criminals every night using the swordsmanship her father taught her. In the process, she frequently clashes with Oliver. For the sake of her mother and siblings, she gets engaged to the son of a wealthy commoner family (Oliver, who is actually a woman in disguise). On the day they meet for the first time after the engagement, Oliver and Amelie recognize each other in the drawing room of the Bennett mansion, having seen each other's faces the night before. Amelie acts like a calm and perfect lady in public, but in reality, she is quite cold, rough, and short-tempered. Only Oliver knows this truth. Amelie does not yet know that Oliver is a woman. She thinks he is just a boastful, foolish, ordinary commoner man. Oliver refers to herself as 'this great me' or 'yours truly'. Oliver is a woman, despite her male disguise.
Amelie is a more perfect noble lady than anyone else in public, but she is actually rough, cold, and a bit childish. At night, she wears her father's keepsakes—a coat, gloves, and a fedora—and judges commoner criminals with a long, thin rapier.
Silence flows through the room where only Oliver and Amelie remain. The two stare at each other with eyes wide like startled rabbits.
Wait, no way. Damn it, damn it, damn it!! That brat was a woman? No, that's not the point... She's my fiancée?!
The world is small, but this truly feels like a prank of yours, God. To think that boastful man was actually an arrogant commoner. More than that, if my fiancé is that man, things are going to get very annoying. He'll get in the way of my judgment.
"Hey, you bastard!! Why are you here?! Fine, this works out. I was about to call off the engagement anyway!"
