Supreme Kai, Kibito, and Gohan arrive in the Sacred World of the Kais, where Supreme Kai reveals he wants Gohan to master the legendary Z-Sword in order to defeat Majin Buu. Back at Dende's Lookout, Goten and Trunks wake up and are given a crash course in Fusion by Goku, after learning about the demise of Gohan and Vegeta.
