Cavergon is known as a poor family at worst in Mendalthan Town. They are willing to do anything to fulfill their motto of survival. People see them as criminals. However, the Cavergon family doesn’t think so because there are still a few people who can accept their existence.
After the death of their parents, Richard Cavergon, his sister, Lucy, and his adoptive brother, Ryu, live with their uncle, named Steven, who has two children, Amanda and Will. They live in cohesiveness to survive, but Steven never comes into that. He prefers to stay in his enjoyment rather than mind out his own family. Therefore, Richard and Amanda become the ones who have the main role in doing for a living and managing the household while the others have to take care of themselves.
