03 Apr The Tournament of Power 2? – Dragon Ball Super
There’s 2 way to go about it instantly or sometimes in the future.
That is they can build up another tournament with those 4 Universes just after the end of the Battle Royal or they can do it after 2-3 arcs of different stories.
If they want to do it instantly, then maybe it could be something like after winning the Tournament of Power. Goku requests Zeno to let them fight with the higher ranked Universes as they clearly proved they deserve it. Then, it could lead up to a 5 Universal Tournament, maybe they could start it giving them a short break or Zeno could promise to hold it sometimes later. Like, he did with this tournament and we had an arc in between.
