Play as Ryumaou To play as Ryumaou, you have to earn your way up to the "Ryumaou Tournament", and then beat it. Virtual Ryumaou To get Ryumaou on the virtual character select screen, beat SD Hiryu with Ryumaou. After beating it a couple of times you should get the "Skull of Devil King" as a random prize. This enables you to pick Ryumaou at the Virtual Hiryu select screen.
