Goku has wiped out the Red Ribbon Army, but he can’t figure out the location of the seventh Dragon Ball! From there, he ends up requesting a divination from the fortune-teller Uranai Baba, who the Turtle Hermit told him about. On the way, Goku and the others stop by Karin Tower and take Upa with them to Uranai Baba’s palace! However, in order to receive a divination from Uranai Baba, one must either pay 10 million zeni, or win in a battle against her five competitors! Goku and the others reluctantly agree to fight, but…

Dracula Man, the first opponent, challenges Kuririn! Kuririn is filled with confidence, but he gets bitten in the head by Dracula Man and has his blood sucked! Having lost a large amount of blood, Kuririn is ultimately defeated by Dracula Man. Goku and the others then work on a strategy, and Upa and Puar participate together. They blow Dracula Man away with the things a vampire hates, garlic and the crucifix! Moving on, they pass the baton to Yamcha, but the next opponent is Mr. Invisible, an invisible man of all things!!

Yamcha has a tough battle with an undetectable invisible man as his opponent! Goku returns after having been instructed by Kuririn to bring the Turtle Hermit and Bulma. Kuririn pulls down Bulma’s clothes when the timing is right, and blood shoots from the Turtle Hermit’s nose once he sees Bulma’s chest! Bathed in this nosebleed, the invisible man’s form appears, and he is defeated by Yamcha. Kuririn’s strategy wins! Meanwhile, the battleground is moved to the “Demons' Toilet”!

The “Demons' Toilet” is lined with demon statues, and surrounded by a poisonous bog! The mysterious third contestant to appear is the mummy man, Mummy-kun! But in contrast to his appearance, Mummy-kun has ultra power and speed that surpasses Yamcha’s. Yamcha faces him with determination, but the difference in their power becomes clear. Still not understanding, Yamcha fights on until the end, but he is finally defeated! Then in place of Yamcha, who put up a good fight, Goku at last debuts!

The fight between Mummy-kun and Goku begins. Mummy-kun attacks furiously, but it is completely ineffective against Goku! Angered, Mummy-kun uses his bandages to attack?! The bandages wrap around his entire body, but Goku doesn’t surrender! Thinking quickly, he uses the poisonous bog to break out of the bandages, then defeats Mummy-kun with a single punch! The fourth person to appear is the devil Akkuman! However, even Akkuman is helpless against Goku’s power?!

Akkuman has a rough battle against Goku’s overwhelming power, and fires the Devil Might Beam. It’s a frightful attack that infinitely multiplies the tiny evil hidden without a person’s heart, causing them to explode! Goku is bathed in the Devil Might Beam, but for some reason it doesn’t work on him! It turns out that Goku somehow doesn’t possess an evil heart!! Goku finally blows Akkuman away! And then the fifth man finally appears, but for some reason Goku feels nostalgic.

The fox mask-wearing fifth man is no ordinary person! A breathless offensive-defensive battle unfolds!! And then the fox mask man fires a Kamehameha of all things! But Goku doesn’t lose, and returns fire with his own Kamehameha, knocking the man down! In the instant it seemed like Goku had won, the fox mask man grabs onto Goku’s weakness, his tail! Seeing this, the Turtle Hermit realizes the fox mask man’s identity. He says that the opponent’s identity is Son Goku’s dead adoptive grandfather, Son Gohan!!

Grabbing onto Goku’s tail, the fox mask man knocks Goku around! But then Goku’s tail comes off!! As Goku is about to counterattack, having lost his weakness, the man quickly surrenders. His identity was Goku’s adoptive grandfather Son Gohan after all!! Goku rejoices in their reunion! Thanks to Uranai Baba, Gohan was able to return from the afterlife for a single day. After the brief reunion, Gohan returns to the afterlife once again!

After having Uranai Baba divine the location of the seventh Dragon Ball, Goku immediately sets off on Kinto'un to find it. But it turns out that the ones in possession of the Dragon Ball are Pilaf and his lackeys, who had previously given Goku and the others a hard time. Goku ends up in a showdown over the Dragon Ball with Pilaf, who is plotting to rule the world! Pilaf confidently challenges Goku in his mecha, the Pilaf Machine. He puts up an unexpectedly good fight, but loses in the end! Goku finally obtains the last Dragon Ball!!

Having collected the seven Dragon Balls, Goku returns to Karin Tower with Upa. Then in response to Goku’s summons, Shen Long appears once again! While he’s afraid of the gigantic Shen Long, Upa still speaks his wish! Hearing the wish, Shen Long brings Upa’s father Bora back to life, who was killed by Tao Pai-pai!! Goku says his parting words to Upa and his father, then returns to his friends. Then at the Turtle Hermit’s advice, he sets out on a trip in search of even greater power!
