Madoka’s family were descendants from the nobles, but they have fallen on hard times. However, due to his father’s financial successes, they’ve regained some of their wealth. His old-fashioned father was strict about speech and appearances and arranged his transfer to the prestigious Ookusu Gakuin to help him become a proper man. On his way to the dorms on the first day, he came upon a beautiful girl in the school’s courtyard, who looked like a princess straight out from a children’s book. While he was entranced by her beauty, she suddenly opened her eyes, looked at him and let out a scream, causing him to run away startled.
When he reached the boys’ dormitory, he found the same girl from before, Orfina, in his room. She is the princess from a small Northern European country who came to study at the school. However, she refused to live at the embassy and snuck into an empty room (which was now his) with her servant Kanon. Even though it was against the rules, she was determined to stay there and ends up taking over most of his room. Thus began his strange co-living with a proud princess. Over time, he became closer to her. Madoka had a difficult time adjusting to the high culture at the school. There is a group known as the Reijinkai where those in the nobility gather. They invited Orfina to join them, but were turned down. After some commotion, he ended up creating the Shakoubu with Orfina to oppose the Reijinkai. Which group would be able to gather more members?
