Out from the Broken Sword

At the Lookout, Goten and Trunks continue their Fusion training with Piccolo while the others pass time playing cards. On the Sacred World of the Kai, Gohan has fully mastered the Z Sword, slicing a boulder cleanly in two with a single swing.

Supreme Kai produces a block of Katchin, one of the hardest metals in the universe, for a true test of the blade. Goku hurls it at Gohan, who swings with everything he has. The Z Sword snaps cleanly in half. Supreme Kai and Kibito are horrified, while Goku notes that the hardest metal in existence earned that title for a reason.

Energy waves ripple from the broken sword, and an elderly Kai materializes before them. He introduces himself as the Eastern Supreme Kai from fifteen generations prior, explaining that he was sealed inside the Z Sword long ago. Goku remains skeptical about the old timer's strength and fires a small ki blast directly at his face.

Old Kai crashes to the ground and screams in outrage, but Goku and Gohan point out that the blast was trivially weak. The ancient Kai admits his reputation came from his intelligence rather than his combat power. In the Other World, King Yemma's staff buckles under 1.5 million new arrivals as Buu's devastation overwhelms the afterlife.

Old Kai refuses to share his secret until Goku sweetens the deal. After offers of Master Roshi's magazines fail to impress (Old Kai can already spy on beach volleyball with his omniscient vision), Goku promises him a date with a beautiful Earth woman. Old Kai eagerly accepts, and Goku privately notes the old Kai is just like Master Roshi.

With the bargain struck, Old Kai reveals his ability to awaken dormant power within a warrior. He instructs Gohan to stand perfectly still and begins dancing around him in a bizarre ritual. Everyone watches in disbelief as Old Kai announces the process will take twenty hours of dancing followed by five more hours of meditation.
