The building was set up like a virtual land and Hassleberry and Syrus were seen in the form of a virtual dinosaur and toy car. Sarina appeared and challenged Jaden and Aster to a duel. The purpose was because Sartorius wanted to see which one of the two was worthy enough to be by his side. Sarina created a mirror clone of herself to make it a tag duel and as they started, it was obvious that Jaden and Aster were equal in strength. Aster refused to help because he wanted to be the one worthy, but then Sarina played a magic card, Full Moon Mirror, and after 10 monsters were destroyed, its true power was about to be revealed.
