Chapter 5: Terrible Triple

A little lore here, Most demons have certain common powers amongst themselves these are the common Demon powers:

Flame control: Able to create and control flames even ones that aren't their own

Lie Detection: Able to detect lies from any living being

Energy sense: Every demon can detect energy, between Demons, Humans, and Angels.

However, if you are contracted with certain high-level demons, you are gifted with certain powers that the demon has control of

For example, if someone made a contract with justice, they are granted the power of the white chains that she, as well as Judgment, are able to use. Here are some powers that Izuku Posses due to his contract with Beelzebub (some will remain a secret):

Void Manipulation: Manipulation of the void and its own powers which slowly weaken opponents

Pestilence: [TOP SECRET]

King of the flies: [TOP SECRET]

Rot: [TOP SECRET]

Currently, Izuku and the rest of the students of Class 1-A were on their way to the USJ. Not Universal Studios Japan, but as Aizawa and Nezu called it, "Unforeseen Simulation Joint". Apparently, this little training exercise was some way to rescue civilians from.

"So, are you guys excited about this?" Mina asked

"I for one am very excited about this training exercise!" Iida cried

"Yeah, I wonder what kind of training we'll be doing while in those disaster zones?" Kirishima cried with excitement

Izuku just ignored the conversation, his mind wasn't worried about the training session. Right now he had bigger problems. From what Beel had told him, it seemed that Lucifer and her secretary, Pandemonica, were here on earth, and he had a pretty good idea why they were here. However, they haven't made a move against him, which was odd. They also seemed to have some sort of relationship with Principle Nezu. However, he didn't have more time to think about it because the bus had stopped.

"Alright, everyone off!" Aizawa said "we're here," Aizawa said

As they all began to get off the bus, and standing at the door was none other than Pro-Hero 13.

"Hello, students!" 13 greeted "Welcome to the USJ"

many students were glad to see another pro-hero training them, Izuku was actually a bit amazed to see 13 here since they were mostly specialized in capturing villains, but this was a rescuing exercise facility, and 13 would make the best teacher for such an exercise.

13 led them into the USJ and as they all entered, the doors behind them closed and they looked at the facility, which was indeed very huge! Izuku himself was amazed by how large this place was.

13 then turned to them all, "Here at the USJ you will be learning how to save lives and the proper way to conduct a search and rescue mission as a hero" 13 told them "Your powers are not meant to inflict harm. I hope you leave here today with the understanding that you're meant to help people" 13 told them

Kirishima looked past 13 and saw the center of the USJ and saw a black portal open, only for many figures to exit the portal itself, just as he saw that, Izuku sensed three similar demonic energy's and he didn't recognize them.
