Shigaraki stepped back, a grin on his face.

  "Player two? Excellent, I've waited a long time for a PvP match... Nomu!!"

  The muscular bird monster charged forwards. Igris cleaved it's body in two, then again, and again, and again until it became hundreds of tiny flesh cubes, falling into a neat pile before Izuku.

  The meat chunks shifted.

  "Mages!" Izuku yelled.

  A shower of fireballs rained down on the Nomu's remains, burning several chunks to ash, and charring the rest.

  The pile no longer moved.

  Shigaraki stared.

  "You really are player two... I need to grind more to match your power..." Shigaraki muttered.

  The doors to the USJ sprang open, and All Might marched through.

  "I AM HERE!!" He yelled.

  A blue disk appeared in the air, to Izuku's right and Shigaraki's left.

  "What's that? Who's doing that???" Shigaraki asked.

  The blue disk grew bigger, sucking in anything nearby.

  "Kurogiri! Get us out of here!!" Shigaraki yelled, sliding towards the blue portal.

  Izuku stood fast, watching the purple portal swallow Shigaraki up.

  "I will kill you one day Monarch. From one player to another, I will win next time."

  Kurogiri's portal closed.

  The blue gate did not.

  Izuku turned his attention to the gate.

  *How is this possible?? I didn't summon this! And it's sucking us in? None of my gates ever did this!*

  Izuku recalled his soldiers, making his armour disappear.

  He heard a shriek, and Watched Momo and Jiro get sucked into the portal. Bakugo soon followed, as well as Kirishima.

  *They must have been caught right behind it..*

  Aizawa took a step towards a portal.

  Izuku grabbed his sleeve.

  "Let me go Midoriya! I have to go after them!"

  Izuku shook his head.

  "I know what that is! It's too dangerous for you, let me go after them!"

  Aizawa lost his footing, stumbling closer to the slightly calmer portal.

  All Might ran forwards, grabbing them both.

  "I will go after the students!" He said.

  Izuku growled, slapping All Might's hand away and leaping into the portal.

  It became dead calm. Apart from the loud Bakugo and Kirishima, and the worrying Momo. Jiro was quiet.

  Izuku waved.

  "Hey everyone. I know what this is, don't worry. I don't know how it got here, but I know what this place does."

  Bakugo marched forwards, but was stopped by Igris.

  "Please listen. If you want to live, and make it home alive, then you listen to me. From the size of the gate I'd say it was an S class, so you'll all be pretty much powerless here."

  Bakugo stared at Igris, then relented.

  "What do we do then Nerd?" He asked.

  Kirishima nodded alongside the question, and Momo slowly calmed down.

  "Kirishima, your defence won't work against the things in here. Don't rely on it. Stay behind me and focus on dodging. Bakugo, same to you. Jiro, your jacks will be really helpful in locating and avoiding enemies. Yayorozu, your creation will do just as well. Come Forth."

  A portion of Izuku's army rose from his shadow and joined the other four student's shadows.

  "They will protect you, to a degree. Now, come on."

  Izuku headed deeper into the cave, keeping his senses stretched out for monsters.

  Jiro tapped his shoulder, pointing down a side tunnel.

  Izuku nodded his thanks, heading down there, waving for them to wait.

  The students heard inhuman grunts and noises, then screeching and screams, then silence.

  "Arise."

  Izuku returned, leading them on.

  "Midoriya..." Momo whimpered. "What is this place..?"

  Izuku sighed.

  "I'll explain later, when we get out. Basically, it's a dungeon full of monsters. Kill the boss and we can go back through the portal. This one is really high level though, because of the size of it."

  A dog like creature leapt out of the shadows at Kirishima, who dodged the animal, watching it get impaled by a sword from his shadow.

  "That thing is just a pet. This cave is the home of a tribe of high orcs. They're very powerful monsters."

  Kirishima kept a more wary eye out.

  Bakugo was good at blasting away the jackals, and Jiro heard them coming even before Izuku. Momo was the technical expert, making traps to throw at the jackals as they approached.

  Izuku soon got tired of their slow trek and sent his main force out to comb the caves.

  *Share Sense..*

  Izuku looked through the eyes of every squad leader periodically, looking for where the high orcs camp was.

  "All of you, return to me." He said.

  Izuku turned to the other students.

  "There are no monsters of any kind around us, the only ones left are down these last hallways. I'm going to go and take the boss down, you stay here."

  The others nodded, except Bakugo who just snorted, looking the other way.

  They waited, and heard loud roars, chanting, explosions, screaming, the clash of weapons.. and then silence.

  "Arise." Echoed through the caves.

  Izuku watched the other four step out of the gate, heading through after them.

  Aizawa and All Might sighed in relief when he came through. It looked like the other four's parents had come too, along with Nezu.

  The gate snapped closed behind Izuku, who heaved a sigh of relief.

  "Was that..?" Nezu asked gleefully.

  Izuku nodded.

  "What rank?" He asked.

  "A+ or an S- I think." Izuku answered.

  "Do you know what kind we can use to train with?" Nezu inquired.

  Izuku sighed.

  "Offensive quirks like Bakugo, Kirishima and Todoroki... B- at best. Skill or circumstantial quirks.. C's." Izuku said.

  The four student's turned back to the teen, away from their parents, who watched on curiously.

  "Alright Deku, what the-"

  "Midoriya.. you said you would explain..." Momo said.

  Izuku nodded.

  "Yes, I did. What you just went through and escaped was an S class dungeon. I can create them with my quirk, under certain conditions, but this one just.. popped up out of knowhere. I use these dungeons to improve myself and my quirk, fighting the monsters within to the death."

  "Do you think the villains caused it to appear?" Nezu asked.

  Izuku shook his head.

  "Shigaraki, the leader, seemed as surprised as us. He wanted to know who was making it." Izuku said.

  Nezu nodded.

  "Okay. Well, it's quite late, so you should all go home for now. I believe we should just start with E ranks and go from there." Nezu said to Izuku.

  *Quest complete!*

  *You have Leveled up!*
