Bab 109: Empty Boss Room

"What a weird place. Why would something like this be inside a cave? Not to mention at the very bottom of it." Nina muttered after seeing the place, but she didn't appear to realize that it looked exactly like a boss room that could only be found in Labyrinths, which was natural for her because she's never been in a Labyrinth before.

However, Leo immediately recognized the gates and the ominous aura that squeezed through the cracks between the gates and permeated the hallways.

"This is a boss room! I am sure of it!" He said to Nina.

"A boss room? Like the ones you find inside a Labyrinth? So this was a Labyrinth the whole time?" Nina was shocked to learn this information.

"I'm not sure if this place is a dungeon or not, but this is definitely a boss room. I have seen those doors before when I explored a Labyrinth with Miss Camille."

"What should we do? We're not supposed to enter Labyrinths without warning the teachers first."
