I'll just go for it.
This'll be an Isekai RP and will be highly influenced by a bunch of shonen and seinen titles mixed with some fantasy.
As the usual formula goes, normal civillians from earth - that'll be you guys - will be transported to another realm. Just your standard otherworldly plot. Also, you must be wondering how? Magic. Is dying a prerequisite? Nah. The whole resurrection trope is optional.
So, you must be wondering what type of world this is gonna be? Well, the setting you'll be plunged into is gonna be some sorta arena. You'll be forced against your will to participate in various events ranging from fighting monsters, playing the role of a hero or villain, journeying to accomplish a certain quest, or even something like a free-for-all match. Why? Well, all of your adventures are gonna be streamed to the masses. How? Magic. By the way, the stronger you become, the harder these events tend to become.
You'll basically become streamers trapped in a fantasy world coerced to entertain the masses. But don't worry, you'll still get paid. Basic commodities that are required to address your daily needs are gonna be covered. But if that's the case, what'll you do with your earnings? Basically, you use it to make life a little bit easier. Better living conditions, higher quality weapons, fancier training facilities, and the like. If certain groups like you, they can offer sponsorships, entailing more money and exclusive gear.
Rumors say that if you earn enough, you might be able to buy your freedom. Some though, get used to this kind of life and just choose to stay. Technically, those who make it high enough in the rankings are seen as celebrities and demi-gods.
And to make things clear, you'll be normies. No blackbelt heavyweight boxing champion space cowboys. But you'll have limitless potential. Those from earth, for some reason, possess incredible learning curves, so they tend to avoid the boring grinding periods and tend to manifest sudden bursts in their physical capabilities or some strange power.
So, what do you say? Fantasy thunderdome/fight club/twitch doesn't sound that bad, right?
