Maria is a new Student at Ouran high school and she stands out because no one knows anything about her. She seems weird because she has a guard dog that follows her everywhere, she usually stays to herself, and she carries herself like royalty. One day she comes into the host club by accident and shatters a million dollar vase. Frantically she begs that the host club doesn't tell her family. They make her their dog or other known as their servant but when she doesn't show to school for two days they start to get suspicious and go to her house. What they find surprises them all.
