Seto tells the duelist he wishes he could join him in acquiring the [[Red Rose]] cards off the Lancastrians, but he is needed to maintain their defenses. After the duelist defeats [[Henry Tudor]] (Yugi), the Yorkists emerge victorious and Seto congratulates the duelist on his victory. Seto then uses the Red Rose cards that the duelist obtains to complete the summoning, but only to accidentally summon [[Manawyddan fab Llyr]]. The Duelist then defeats [[Manawyddan fab Llyr]] in a duel. Afterwards, Seto apologises for the trouble he put the Rose Duelist through, giving the duelist a pendant, saying to show to his decendants in his/her time if they are in trouble, pledging his family's loyalty to the poweful duleist duelist before reversing the spell and sending the Duelist home.
