Majin Buu has obliterated eighty percent of humanity, and Earth pins its last hopes on Mr. Satan. The champion arrives at Buu's house armed with poisoned chocolates, an explosive handheld game console, and sheer bravado, but every scheme backfires spectacularly. By chapter's end, the would-be hero finds himself serving dinner and scrubbing Buu's back in the bathtub.
In a single day, Majin Buu has wiped out eighty percent of Earth's population and leveled most of its cities. He treats destruction like a game, delighting when people flee or resist. Those he does not blast outright, he transforms into candy and devours. The military has intervened and been annihilated, leaving the survivors to place all their faith in one legendary figure. Via radio broadcasts, word spreads that the man who defeated Cell has recovered from his tournament fatigue and is ready to act. The Royal Army airlifts Mr. Satan to a safe distance from Buu's dwelling, and the champion sets out with a duffel bag full of secret weapons.
Mr. Satan discards his cape and belt, then calls out to Buu in a barely audible whisper. When his military escort shouts on his behalf, Satan panics and dives behind a rock. Once the soldiers leave, he creeps toward the house using a small shrub as camouflage. Finding the place empty, he taunts Buu boldly, only to drop to his knees in apology when a noise startles him. It turns out to be a lizard.
Buu appears on the rooftop and descends, casually asking Satan what kind of candy he would like to become. Thinking fast, Satan presents poisoned chocolates. Buu eats them without ill effect. Next, Satan offers a handheld game console rigged with explosives. While Buu plays, Satan retreats and triggers the detonation. Buu survives completely unharmed and declares it was a fun game.
Amused by his antics, Buu decides to keep Satan as a personal servant rather than kill him. He offers Satan candy made from transformed humans. Satan chews reluctantly, praising the taste before spitting them out when Buu looks away. He then elbows Buu in the back of the neck, but Buu does not even notice the blow. Satan manages to trick Buu into posing for a victory photograph, standing triumphantly over a reclining Buu. Satisfied to have a souvenir, Satan resigns himself to servitude, cooking meals and washing Buu's back while scheming for another way to defeat him.
