The official Toei Animation YouTube channel posted a 60-second trailer for Dragon Ball Super's upcoming Future Trunks Arc.
The new story arc will start on June 12th with the show's 47th episode titled "SOS From the Future! A New Black Enemy Reveals Himself!"
In the episode, a new enemy named Black appears and was easily defeated by Future Trunks even in his Super Saiyan form. Because of this, Bulma is resolved to make a time machine and ask help from Goku and Vegeta from the past, but after half a year, she only accumulated enough fuel for the time machine to make a one-way trip. Black appears again before Bulma and Trunks.
