The name "Ruud" originates from the name of God, as it was perfected by "James," one of the 12 apostles who received power from Lugard, the god of the MU continent. This currency is used to purchase blessed items.

It is known that Ruud can only be obtained by passing Lugard's trial. Research is ongoing into ways to obtain Ruud on the current MU continent. The only known method is to pass the trial of the MU continent.
