Predictions for how this arc ends: I doubt MC will get to S rank at the end of this gate or even end up fighting/killing the S rank that is after him. MC is going to come out of the red gate and the murderous S rank is going to instantly launch an attack him. MC will either dodge or block it shocking both the guild master and the guild associate guy who tested him for the re awakening. After that Those same two will butt in to stop the S rank from going all out and buy MC time to keep getting stronger. That crazy S-rank probably wont fight him until an A or S rank dungeon pops up and they are both are sent in to clear it, where they will have a massive battle.
