Riku Family

The Riku Family is a royal bloodline which ruled the Dressrosa Kingdom since eight-hundred years ago, until ten years before the current timeline. It was one of the new royal families born after nineteen of the twenty kings that founded the World Government left their kingdoms with their families to live in Marijois.

Members
The only members known so far are Rebecca, Scarlett, and Rebecca's grandfather the king Doflamingo dethroned.

Past
Eight hundred years ago, the Riku Family became the new rulers of Dressrosa Kingdom, after the Donquixote Family left the country to live in Mariejois.

Ten years ago, a member of the Donquixote Family, Donquixote Doflamingo, came back to his clan's original kingdom and ousted the Riku royalty, regaining the king status. The king and Scarlett were killed, leaving Rebecca as the sole heir to the Riku Family.
