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 Kuririn to ask if he knows where Goku went. Kuririn 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 Demon Sealing Wave (魔封波 Mafūba), or Mafuba, which is an ancient technique used to seal demons in jars. Wondering what the Mafuba is, Goku quickly teleports to Kame House. Goku spends the night at Kame-Sennin’s house training to master the Mafuba Wave, while Vegeta trains in the Room of Spirit and Time (精神と時の部屋 Seishin to toki no heya).
