Oh right, but it's still not much input. We know ONE sometimes says stuff like "Just have X heroes fight Y monster, they can't defeat him he's for Saitama".
And Murata ends up creating a 120 pages long chapter with the heroes having an epic fight and destroying the monster with it regenerating after the fact even stronger. So he finds loopholes to make it more interesting and the choreography is all his doing.
I can imagine Toriyama giving him vague stuff about the Tournament of Power like the elimination order for the protagonist, a plot point like Blanco vs Jiren being the final and just letting him do his own thing.
I think Toyotaro is already like that, his tournament is too different from the anime, but Murata would make it fun.
