We start off with Gowase and Zamasu on Planet Babari. Gowasu reveals Time Rings are rarely used. The last instance was 400 years before he was even a Kaioshin student. Zamasu seems to have no experience with them, however he is actually aware of Time Rings and the concept of Parallel Worlds/Timelines here.
Rules for Time Rings are the same as the anime. They allow the user to travel to the future and back to the present. It's impossible to travel to the past; such actions are forbidden.
There shouldn't be any doubt at this point, but we get outright confirmation that timeline splits affect all the universes, not just the one it happens in. Gowasu explains that the first parallel world, and the resulting Time Ring, was created via a time machine made by a human/mortal from an advanced civilization in Universe 12. Zamasu notes that there are 4 Time Rings on the top row, meaning there are 4 parallel worlds. Gowasu only remembers 3 when he last checked: "Could it be that someone created another world recently?"
Unfortunately, the timeline/parallel world situation still isn't perfectly clear beyond the first one being created by Universe 12. The latest one does seem to be for Trunks, but that's still not actually stated. Which leaves the fact that Cell altered history at an earlier point, and thus should have created one too, in limbo. I suppose the two middle rings could be Trunks and Cell, while the last one is the Black!Zamasu ring in the manga? It's really still a waiting game to find out for sure.
Potara stuff, fusion joke, 1000 years. Stuff we all know. Zamasu is much more forthright with his hate of mortals and Gowasu is, thankfully, still not blind to it. When the Babarian attacks, Gowasu's request that they flee Babari. Zamasu ignores him. He then proceeds to try 3 more times to get Zamasu to leave and stop what he's doing, but Zamasu continues to ignore him. He's dead set on killing the "useless trash". When they return to the Universe 10 Kaioshin Realm, they have what felt like a more meaningful discussion about Zamasu's actions than the anime did. (Also, Zamasu doesn't really address Gowasu by name in the manga, just Kaioshin-sama.)
Dragon Kart time at Capsule Corp. Not much to say here, as the visuals are pretty self explanatory. The controller Beerus broke after losing at the game was his third one though.
We don't get Trunks feeling quite so useless as in the anime. Future Trunks is happy he's able to relax a bit by playing games. Vegeta and Goku say not to worry, they'll take care of Black and restore peace for him. This upsets Trunks a little that he can't handle it himself. Vegeta also says to make sure Future Trunks doesn't get in their way. So when Trunks wakes up, he's to come to the gravity room for training.
The Godtube stuff is switched. Gowasu walks in on Zamasu searching for Goku and asks if he's quitting his training to be a Godtuber. Gowasu notices the video is the Hakaishin Invitational from last arc and notes he wanted to watch that. Gowasu ask why Zamasu is searching for "that guy who's stronger than a god". Zamasu defects by pointing out even Zeno-sama was attending. Gowasu is surprised the event is more important than he had thought. We switch back to Capsule Corp after the same inquisition into the Super Dragon Balls. (I was curious if Zamasu knew about Zeno. Question answered. Also, there's currently no paradox. Zamasu is on a path of interest in Goku without having met him yet, and Black hasn't caused the heroes to gain an interest in Zamasu. So this is fully possible in the original version of the timeline without Trunks showing up.)
The next morning, Beerus is still upset that he kept losing at the game. He orders a whole barrel of his namesake (beer). Kaioshin appears (without Kibito, suggesting he can use the Kai Kai in the manga too?), having been summoned by Beerus about the evil god investigation.
The Hakaishin asks if there are any gods with evil ideas, like hating mortals. After thinking about Kibito freaking out about mortals in the Kaioshin Realm during the Boo Arc, Kaioshin suggests that he was worried about his attitude. Beerus isn't surprised: "That bastard has a suspicious face." However Goku doesn't think it's likely. Still, they prepare to go meet with him.
Before they can leave, Whis gets a call. Instead of Zeno, like in the anime, it's the Dai Shinkan/Grand Priest. Beerus spits out his beer all over Kaioshin when Whis reveals that Goku has been summoned by Zeno. Goku wants to wait, but Beerus tells him to go now. The rest is the same as the anime: Whis would take 2 days, Kaioshin can teleport them. Goku's clothes aren't formal, don't talk about Black or time travel. Only difference worth mentioning at this point is that Beerus tells Kaioshin directly not to die at Zeno's. Guess that means he's not linked to the Elder Kaioshin, for whatever reason.
