"We don't know who exactly were chosen but the portals were put at specific places, and if only the hunter was strong enough as that if B rank, he would be sucked into the Portal..."
"Oh..."
"They all have been gathered near the entrance of a dungeon which is believed to be..."
"Believed to be?"
"Haha, it's believed that it is an S-Rank dungeon which has 2 BOSSES!"
"..."
"What the heck!!!? Are you serious!!!?"
"Yup... dead serious!"
"Oh my God, this is dangerous! But why the fuck are they calling only B rank hunters?"
"No idea about it. I am just doing what I was asked to do."
Dun Young was pretty much tensed since the matter was not as simple as it would seem. Appearance of any normal S-Rank Dungeon or gate is itself a huge threat but appearance of an abnormal S-Rank gate is beyond comparable.
Also at least one S-Eank hunter lee party is needed to clear this and that too isn't sure that they can clear it by 100%!
