While attending a reunion on Turtle Island with his old friends Master Roshi, Krillin, Bulma and others, the festivities are interrupted when a humanoid alien named Raditz not only reveals the truth behind Gokuu's past, but kidnaps Gohan as well. With Raditz displaying power beyond anything Goku has seen before, he is forced to team up with his old nemesis, Piccolo, in order to rescue his son. But when Goku and Piccolo reveal the secret of the seven mystical wish-granting Dragon Balls to Raditz, he informs the duo that there is more of his race, the Saiyans, and they won’t pass up an opportunity to seize the power of the Dragon Balls for themselves. These events begin the saga of Dragon Ball Kai, a story that finds Goku and his friends and family constantly defending the galaxy from increasingly more powerful threats. Bizarre, comical, heartwarming and threatening characters come together in a series of battles that push the powers and abilities of Goku and his friends beyond anything they have ever experienced.

Losing a loved one is so painful that one may sometimes wish to be able to resurrect them—a weakness that the enigmatic Millennium Earl exploits. To make his mechanical weapons known as "Akuma," he uses the souls of the dead that are called back. Once a soul is placed in an Akuma, it is trapped forever, and the only way to save them is to exorcise them from their vessel using the Anti-Akuma weapon, "Innocence." After spending three years as the disciple of General Cross, Allen Walker is sent to the Black Order—an organization comprised of those willing to fight Akuma and the Millennium Earl—to become an official Exorcist. With an arm as his Innocence and a cursed eye that can see the suffering souls within an Akuma, it's up to Allen and his fellow Exorcists to stop the Millennium Earl's ultimate plot: one that can lead to the destruction of the world.
