Dragon Ball Super S02E04 - I've Come Too! Training Begins on Beerus' Planet!

Goku and Whis arrive on Beerus' planet, where Vegeta is tasked with housekeeping. Goku is surprised to learn that Vegeta has gotten considerably stronger training under Whis. Goku wants to start his training right away, but learns that he and Vegeta must first carry out some house chores that include changing Beerus' bed sheets without waking him up. When the actually training occurs, it quickly wears Goku out as he falls asleep while Vegeta continues. The next day, Whis decides to have a sparring match with his apprentices in order to gauge their speed. The two prove to be no match for Whis., and both are too slow to land a single hit on Whis. Somewhere in space, surviving members of Frieza's army are led by Sorbet. They continue their efforts of resurrecting their leader. Not far off, mysterious beings similar to Beerus and Whis have destroyed a planet in search of something.
