I'll explain the system in more detail.
There will be a roulette wheel that will choose your destination, a world, be it anime, movie, manha, or comic; it's multiverse for a reason.
If the world is very dangerous, there will be a survival pack so you don't die the first time. I'll add the worlds as you go, so this is just in case.
In the world, you won't be able to force anyone; it's called recruitment, not slavery. You have to convince someone through your own means to leave their world to join you, so you can't recruit just anyone.
You have a time limit, so as not to make the arcs for each world too long: 120 hours. 5 days seems fair enough.
Once the recruitment is successful, you'll leave that world when the 120 hours are up, or if it ends early, you can still do so.
When you do, you'll gain a random power from the world you visited, so you don't have to rely entirely on your recruited companions. You'll also receive a reward based on the person you recruit, whether it's a random skill, trait, or talent from your companion.
It will have a shop, which will run on World Team Reputation points.
R.E.M.
Basically, the more well-known the protagonist's team is, the more points they'll earn, which they can use to buy things from the worlds they've visited, either for themselves or their companions.
I thought it was necessary to explain it, since I invented this whole system, which, as you'll notice, was somewhat inspired by a group chat system.
Or at least I think I invented it, since I've never seen anything similar in a fanfic.
Well, please support it, and bye.
