When a mysterious villain threatens to open the gates of Hell, a devilishly handsome demon hunter could be the world's best hope for salvation.

After saving the world from the destructive might of Majin Buu, Gokuu Son and his allies look forward to a well-earned rest. However, unbeknownst to them, their battle was recorded and observed by Gomah, an evil being who assumes the title of King in the Demon Realm, filling the void left behind with the death of former ruler Dabura. At Gomah's side is Degesu, the younger brother of Higashi no Kaioshin, a being who lords over the universe. Jealous of his brother's power, Degesu works alongside Gomah to steal Earth's Dragon Balls and preemptively subdue any potential future enemies. Calling upon the power of the legendary dragon Shenron, Gomah wishes for Gokuu and his friends to be reverted into children, intending to rob them of the limitless power that defeated Buu. With Earth's greatest warriors shrunken down, Gomah abducts Dende, the planet's acting god. But Gokuu refuses to be set back by his new body, working to master his younger form to fight as proficiently as he could as an adult. Joined by Kaioshin and Glorio—a mysterious but seemingly rebellious demon—Gokuu pursues Gomah to the Demon Realm in order to rescue Dende and restore his friends to their natural ages.

The chaotic aftermath of a confrontation between Jinka Yamato and Yazen results in the power dynamics between the magically gifted katawara and humans being turned upside down. As the news of the downfall of dangaishu—the katawara-hunting monks led by Yazen—spreads across the country, rogue groups of katawara start to form, worsening the already-fragile relationship between them and humanity. Having lost faith in his abilities, Shinsuke Hyoudou now spends his time heavily drinking in the company of Senya, a former enemy of his who controls one thousand katawara within his body. Senya indirectly causes the death of the father of Tsukiko, his newfound friend, after a surprise attack of a local god gone berserk. Despite the circumstances, Tsukiko holds no grudge against Senya and is determined to become Shinsuke's disciple no matter what. Although Shinsuke refuses to become Tsukiko's sword instructor, he reluctantly agrees to let her travel with him and Senya. While the unlikely trio heads towards their next destination, Tama Youko continues her journey to find the trail of Jinka, the nine-tailed fox who has the power to destroy the world.
