Darkness enveloped them when Monika cried, telling everyone to escape. Elena's shadows flickered as three skeletons emerged from within them, wrapped on wooden armors, one holding a small sphere which generated a wall of darkness protecting Elena and her friends from the explosion and the impact of the Dungeon being created.
"Shit! The wave of Mana is coming! Everyone's going to get sucked inside of that gate!"
"We can't save everyone! Protect the young lady and her friends!"
"Huh?! Everyone's unconscious!"
The skeletons noticed that seconds before the dungeon gate was created, every student fell unconscious, one of them swiftly realized the reason.
"It must be the Mana Shock! Their bodies ended taking on the Mana that came out, forcing their bodies to adapt!"
"Shit, are some of them turning into zombies?!"
"Grab the young lady and her friends! Quickly! Shadow Orb!"
