La Familia De Pitié is the top of the seven stringent and fierce clans in the modern world. The head of La Familia De Pitié, Leo Von Richett, was a very strict and cold leader. He had two children, Hennah and Hannjoh, the two were very opposite to each other. Strong and weak, you can easily identify who was the strong one.

Hennah inherited her father's physical strength and abilities, the ability to rule the clan. Hannjoh, who was so weak, had a very fragile body, which he had since he was born. But even though they differed from each other, Hennah cares a lot about her younger brother. Hannjoh respect and love his sister so much. They're taking care of each other. Leo Von Richett, a father who is strict and very cold from the outside, didn't show anything even a twitch you cannot see it from him. But even though he did not show anything, including to his children, he's a very concerned father and concerned leader of his clan members who are under his protection.

He started training Hennah when she was eight years old, he saw that Hennah had the potential to be a leader of the whole clan. Until she turned nineteen years old, Leo Von Richett handed the whole authority to rule the clan to Hennah. Hennah who is strong enough didn't think twice about shouldering the responsibilities that her father entrusted to her.
