I'll Protect the World! Trunks' Furious Super Power Explodes!!While Future Trunks' new form is enough to match Goku Black, Future Trunks is still unable to deal the death blow. Future Trunks tells Vegeta to take Goku back to the past, while he faces their opponents. Goku Black attempts to prevent them from escaping, but he fails to do so. Goku, Vegeta, and Bulma arrive in the present. Vegeta explains what happened in Future Trunks' timeline and Goku Black's origin to Beerus and Whis. Believing they had done their part, Beerus and Whis leave. Meanwhile, Chi-Chi and Gohan meet with Krillin to ask if he knows where Goku went. Krillin hesitates and dodges the question. They leave for Bulma's house to ask her the same question. Once there, they meet Goku in bandages. With everyone present, Piccolo thinks of a new plan. He proposes using Evil Containment Wave (魔封波 Mafūba), which is an ancient technique used to seal demons in jars. Wondering what the Evil Containment Wave is, Goku quickly teleports to Kame House. Goku spends the night at Master Roshi's house training to master the Evil Containment Wave, while Vegeta trains in the Hyberbolic Time Chamber.
