There is a yacht party in the sixth episode of "Dragon Ball Super," and it will welcome some uninvited guests. 

Based on the trailer for the upcoming episode titled "Don't Anger the God of Destruction! The Heart-Pounding Birthday Party," Beerus is slated to arrive at Bulma's supposedly fun party. But despite the danger looming ahead because of the arrival of the God of Destruction along with his attendant Whis, Bulma chooses to welcome them aboard the yacht. Surprisingly, Beerus seems to be having a lot of fun. He even looks amused at the crowd. 

All the while, Vegeta is keeping an eye on the two unexpected guests while hiding behind the bushes to see if they will do something that could disrupt the merrymaking. 

While Bulma appears to be glad to see that Beerus and Whis are enjoying the party, the two are still plotting something evil. The God of Destruction is later seen getting angry.

Goku's voice is also heard in the trailer, saying, "Vegeta, taking care of earth is not gonna be easy." 

In the previous episode titled "Decisive Battle on Kaiō's Planet! Goku vs. God of Destruction Beerus," the antagonist arrived in King Kai's planet to look for the Super Saiyan God. King Kai decided to hide Son Goku in his house and attempted to distract the vicious visitor who has awakened from a 39-year sleep, earlier than the Kais expected.

But since Beerus and Whis failed to see the Super Saiyan God, he will not stop until he gets his revenge and continue his plans for world domination. This means that there will be a lot of challenges that the protectors of Earth will have to face in order to keep the peace and quiet that Son Goku and his team fought hard to achieve in the past. 

"Dragon Ball Super" episode 6 is scheduled to air on Sunday, Aug. 16.
