If I'm reading it right, the plot is to beat the towers to unlock the main scenario which is if they beat gives the earth another year of survival, but if they fail the entire world ends. If they ignore the towers, they will release the monsters within to destroy the world as well. Our MC had been approached by a "deity", they call Elders, during the second year of clearing the towers and offered a deal [Jester that is] and allows him to be granted benefits from many Elders (Deity's).
That deal he made may work in his favor of growth, but no one will ever take him seriously because he wears these masks. The only ones we've seen thus far understand him is the Saint (who looks more like a paladin or holy knight) and the guy who works in the intelligence jurisdiction of the government. The guy who had before the towers first appeared been helping our MC get ready to go Pro in gaming.
So everyone else believes he's a thug who couldn't care less about the world, but we can see he does care. He has at least one person he cares about who had been there to save him when the towers first appeared and still checks in on him.
We don't know how many rounds of towers and main scenarios there will be, nor have an idea on if there will be an end. All we can see is that everyone is leveling stats and skills in order to get stronger. The way that last chapter ended, it seems like Jester wants our MC to be the villain.
The plot could be there, since it appears with this "season's" towers are unlocking themes towards the main scenario that will have connections to certain tower inhabitants he saves. Looks to be each story plays a key point, but we don't know how or why, since they started with the final boss of the 5th main scenario season end play. We have no idea beyond that it dealt with the Elder of Plague. So we're to assume an Elder is the final boss, but does that have to do with the towers?

I can see plot potential, but it's still early, and it's still coming about. That's at least my take on what I've read thus far.
After reading it, I don't understand anything. Where's the plot? In each chapter, they insert a new scenario or event, and then, when it ends, a new one again? It's like a player who just continues a quest in a game. It is a bit similar to ORV because of the gods, but this one doesn't have a plot or background, just pure OP Mc. It's not hyping me up because scenarios and events were all over the place. They just keep introducing characters to make MC look more OP, lol. It's not giving for me ╮(￣▽￣)╭
