Videl suggests that Gohan helps his father. Pan appears, flying into her mother's arms, happy. Gohan, proudly watching, decides to join his father, vowing that he is not willing to lose everything that he loves.
Mr. Satan appears with Buu and Bee. Mr. Satan greets Goku. Goku flies past him and goes to Buu, also asking him to join.
Goku takes Gohan and Buu, with Mr. Satan, back to the Sacred World of the Kais. After a few questions, Beerus secretly asks Goku if they know about the stipulation.
Goku answers that he only told Gohan, and they agreed to keep it a secret to avoid panic, with Beerus agreeing as well.
...
Supreme Kai takes the entire group and gets them to Zeno's Palace. While there, Beerus warns the group to avoid saying or doing anything careless.
While they walk to the main altar, the group meets the Universe 9 group: the Supreme Kai Roh, the God of Destruction Sidra, his angel Mohito, and the 3 fighters representing them, the Trio of Danger: Bergamo, Basil, and Lavender.
The Grand Minister gathers both groups and transports them to the World of Void, where he has prepared a World Martial Arts Tournament-style ring with spectator seats.
The Grand Minister then calls for every god in the multiverse to appear and every single God of Destruction, Angel, and Supreme Kai from each universe, all gather to spectate the match.
As Goku loudly greets Champa, the Grand Minister orders Goku to be silent. The Grand Minister then explains the Future Zeno's request to watch a tournament match as he has never seen one before, and he and Zeno appear to spectate.
Goku flies to and greets them, calling them "Zennys," and Champa is flustered at Goku calling them "Zennys." An embarrassed Beerus immediately grabs and throws Goku back to the seats, apologizing to the supreme god.
The other disgruntled Gods speculate on how vulgar and impudent Universe 7 is acting. The Grand Minister, overhearing them, announces that the Tournament of Power was Goku's idea. Zeno's initially, but he forgot about it until Goku reminded him. Goku thanking the Zenos for letting them fight first.
Grand Minister explains the rules for the fights: there will be one-on-one matches in order, there is no time limit, and the winner will be chosen if his opponent surrenders or is unable to continue fighting.
Roh greedily asks Grand Minister if there are any prizes, and the Grand Minister answering the purpose of this match is solely to provide anticipation for the tournament and to show Future Zeno what a tournament is.
Sidra nervously asks if they will be destroyed on the spot if Zeno considers the fighters to be boring, and Grand Minister answers about its possibility, as all is as Zeno wills it.
Then Grand Minister calls for the two beginning fighters to go to the stage, Basil, the youngest, goes first. Just like they decided, Goku decides that the first fighter will be Buu, but the group notice that Buu fell asleep during all of the talking. Beerus quickly orders Mr. Satan to wake him up, Mr. Satan wakes Buu with a chocolate bar, promising more if he goes to play with Basil. Buu agrees and heads to the ring.
With both fighters present, The Grand Minister announces that the rules will be improvised as the tournament goes along.
Basil overpowers Buu and seemingly beats him, which causes Roh to prematurely gloat about the "superiority" of Universe 9.
However, an enraged Buu emerges unscathed and launches a Majin Kamehameha at Basil.
This inflicted extreme damage to him, although, Basil appears to be unscathed, as he approaches Buu, his body cramps and collapses due to the side effects of the power-up drug he dosed, returning to normal in charred rags afterwards, the Grand Minister clinches Universe 7 the victory.
As the Universe 9 team laments Basil's loss, Lavender commenting that if he had been allowed to kill his opponent, then he would have won. Gohan volunteers to fight next against Lavender, who is allowed to kill to his heart's content.
The next match of the Zen Exhibition Match is Gohan of Universe 7 against Lavender of Universe 9, later, as Lavender silently chuckles to himself, Gohan suggests to himself that he must see how Lavender fights with his eyes since his ki cannot be sensed, with Goku advising him from afar. Later, The Grand Minister commences the match to begin.
After all the hustle and bustle, all three matches were completed with one draw and two won by universe 7, then universe 9 was erased.
Then the Grand Minister explains that he will begin creating the arena for the final Tournament of Power, which will be completed in 40 Earth hours.
Back at the Sacred World of the Kai, Beerus, and Goku get into an argument over Goku's laid-back attitude and Beerus' hypocrisy, which Whis breaks up. The group agrees to convene at the Capsule Corporation to discuss their strategy.
...
While in the Present Timeline,
Eero was sitting at the edge of the island, looking at the conclusion of the match in front of him on a golden projection screen. It is replaying the Zen exhibition match which happened a day and a half ago.
Instantly, Goku teleports beside him.
"Eero, we need your help," he said hurriedly.
Eero raised his eyebrows, waved his hand, dismissed the projection, and nodded thoughtfully. "Well, let's go. It's time to meet the strongest being in this multiverse."
"Thank you, I knew you would help us," Goku patted his shoulder, then transmitted to Capsule Corps along with Eero.
At Capsule Corporation, Chi-Chi is preparing a feast for the new baby when Goku and Eero arrived instantly.
Eero glanced at Beerus, Majin Buu, Hercule, Whis, and Gohan. While Chi-Chi and Gohan greeted him, he nodded and greeted in return with a smile.
Chi-Chi offers the food to them since the baby hasn't been born yet, and Goku and Beerus happily leaped. Eero also ate a little.
