"Yu-Gi-Oh! Duelists of the Roses" is a PlayStation 2 video game released in 2004. The game focuses on the myth and culture of the Yu-Gi-Oh anime series. Playing the part of a card duelist, you are tasked in this action-card game with defeating different opponents to progress through the game and attain new cards. One of the cards you can attain in the game is Riryoku. This card can be obtained only in one way.
Go to the “Competitors” list.
Choose “Manawyddan Fab Llyr.”
Fight and defeat Manawyddan Fab Llyr in a card duel. You must defeat him in fewer than 10 moves. However, since you cannot predict what moves it will use, you might have to do this fight more than once.
Choose “Reward” when Manawyddan Fab Llyr asks what you want in return for defeating him. You will be rewarded with the Riryoku card.
