they're players that suddenly got into the game, where each of them become the king of an empire and has a grandduke. it also seems that this game has rankings that based on tower level that player's kingdom cleared, our mc is on the first. the biggest problem is that there is a big and dangerous creature who could destroy their world, even the earth. I also didn't really get abt this, but bc of that they need to clear the tower more faster than usual, now they're reached 90 floors with special condition. this floor forced every player to join and it has a scenario to clear, mc faced a scenario that based on his kingdom past
there are more details, especially how mc and ml's relationship, I just mentioned the main plot problems I guess...
