Serena, Sartorious' sister, guides Jaden, Aster, Grandpa, and Bastion to Kaiba Land. Aster and Jaden go inside the Virtual World to see Syrus and Tyranno as a Vehicroid and a dinosaur. Then Serena tells them that the only way that they can get out and save Syrus and Hasslebery is if they defeat her in a duel. The duel is also being held to see who is the chosen one to stand by Sartorious' side. (thetvdb.com)
