Incoming Dangers...

B-rank Dungeon, Lava-lake, barren area

Several students could be seen attacking a single big lava worm:

[Mutant Lava worm: Rank- (B-)]

"Seriously, this thing is very huge!"

"Yeah! As expected of a B-rank dungeon!"

"Oy! Dodge! That lava worm is about to throw its acidic saliva!" 

"Yeah!"

Looking around you could see about twelve students from various classes teaming up to fight this gigantic mini-boss-type monster. 

While the students were busy fighting the monster, suddenly a spatial gate opened out of nowhere directly above the head of the lava worm, A person wearing dark black armor, with golden linings on it walked out of it, but strangely he didn't fall to the ground immediately.

Suddenly, two bat wings appeared from behind him and stabilized him in the air, a strange golden emblem could be seen on his armor's chest plate and the cape.
