Tsuna had risen before the sun the day of the field trip. It might've been nerves or it could be the way his mother was hesitant to sign his permission form. Reborn had greeted him with some odd advice, "Tsuna make sure you have your headphones with you on the field trip."
"I will?"
"They could be more important than your mittens."
Tsuna was a little freaked out but he had no time to dwell. He was off to catch an earlier bus because of the field trip. Class "started" almost two hours earlier than normal because of the trip to the Unforseen Simulation Joint Facility. Tsuna didn't know anything about the Facility and Izuku was his sole knowledge on the Space Hero, 13. He didn't get to take his usual nap on the long ride because his netves just would not calm. What would the simulation consist of? Could he complete it? Was enrolling into U.A. the right move?
The thoughts plauged Tsuna all the was up to the door of the classroom. No one besides a few teachers and Class 1-A were in the building. Aizawa quickly took roll before leading the students to the bus. Everyone seemed excited, which helped calm Tsuna's nerves, and were animatedly chatting about their dreams of Heroism.
"Tsuna, I have a few more questions about your Flame."
Tsuna looked back to see Izuku with his pen and notebook, having a gleam in his eye that was kind of overbearing to Tsuna. "S-Sure. What do you want to know?"
Izuku started to mumble to himself to the point that everyone started to look at him with a look that was worried crossed with confusion. A few questions could be picked out of the stammering but it wasn't until Katsuki snapped at Izuku, "OUT WITH IT, DAMN NERD!"
"R-Right! Tsuna," Izuku flipped through his notes, "why were you able to stop my punch?" This comment caught everyone's attention almost immediately.
"Well its from a technique I had revised awhile back. Zeropoint Breakthrough: Custom."
Bakugo jumped from his seat in anger, "YOU! You were able to stop Deku's punch?!"
"Y-Yeah... but i wasn't able to fully use-" Tsuna was cut off as the bus stopped and Aizawa told everone to "Shut up" as they have arrived. Their instruction was simple, the boys go to the Men's Locker Room while the girls went to the Women's, and after they followed them they were to meet up at the main gate.
As everyone was getting changed into their Costumes, two students wire their Gym Uniforms. Tsuna and Izuku were almost one in the same besides the fact Tsuna's "costume" was a ploy to trap the other engineer between Giannini and Spanner. Aizawa allowed them to as it was too late to disagree.
In the Men's Locker Room one male student was losing his cool, Minoru Mineta. "G-Guys!!!" He shouted almost too perverted, "T-There i-it is..." Very few paid attention to him either because of his perverted nature or the fact most had more conplex costumes to change into. Minoru started to ramble like Izuku would but it was more about which gurl he wanted to see. Out of the peep hole he found came Kyoka's plug-like earlobe, stabbing Minoru in the eye, "Sawada, that better not be you!"
Tsuna's face made a deadpanned expression, Why am I being targeted? He shook his head and continued to get changed. Like he promised Reborn he put on his 27 Headphones and Contacts. It was only a few moments longer before all of 1-A stood in front of the main gate where 13 greeted them.
"Welcome Everyone, I've been waiting to meet you all!"
The students were were in awe, "The Space Hero, 13! The Hero that has resqued tons of people from disasters!" Izuku continued to mumble more stats to himself as 13 went on to show the students where they would be tested. The landscape was awe inspiring, split into four large sectors, and containing natural disasters from all four elements.
"Now, who is ready to save the day?"

All Might and Principle Nezu sat in the Teacher's Lounge, "Aren't you supposed to be with 1-A?"
"Ah, Principle Nezu! Y-Yeah but I spent too much time Hero-ing on my commute to school this morning."
Nezu laughed to himself as Toshinori will always be the same. He had 3 hours in his All Might state and somehow managed to be 3 hours late to school. "To be a deterrance is one thing Toshinori, but when do you stop being the hero and start training the hero?" Toshinori thought long about Nezu's statement. Even though the small Principal meant all of the young wannabe Heroes in Class 1-A, Toshinori took it as a means to train Midoriya a little more properly.
After theor little chat the room was pretty empty. A teacher would pop up every now and again but nothing really important. The news was still covering the deeds of All Might from the morning while he worried about the students at the training exercise. Aizawa and 13 were great heroes, so their instruction is benefitting for them. Right?
It wasn't until Toshinori tried to get in touch with Aizawa that something felt off...

"So the exercise will start like-"
Shoto Todoroki noticed a strange black smoke behind 13, "W-What is that?" The smoke turned into a flame-like state and then a portal. Eraserhead and 13 were in way over their heads as an endless stream of small time Villains started pouring out, lead by a young man with hands grasped all over his body and face. Before Class 1-A could react, small portals opened beneath them, separating all the students at random.
The students were broken up into threes. Izuku, Tsuyu, and Minoru were sent to the Water Sector, landing on a yacht. Kyoka, Momo and Denki landed on a rocky plane in the Earth Sector. Tsuna, Katsuki, Shoto, Tenya, and Fumikage were left by Aizawa while Ochaco and the rest were with 13. "Eraserhead, they have cut our comms! We can't reach anyone outside."
"Damn... they have us completely isolated."
As the villains started to close in, Eraserhead and 13 got to work. 13 tried to stop the the man who was controling the portals and allowing more villains to come in, he was identified as Kurogiri with the Quirk Warp Gate. 13 was using her Quirk, Black Hole, in an attempt to suck Kurogiri into nothingness.
Katsuki and Shoto responded immediately, using their abilities to take on the small time villains and gangsters that flooded the area. Tsuna ingested two Dying Will pills and put on his mittens, with his Dying Will Flames and his Hyper Intution, none of these villains were going to touch him.
"Bakugo, Todoroki!" Tsuna shouted, "one of you go to that burning building while the other goes to that glacier!" He sounded almost like a different person to the two Genius Quirk users. Tsuna dodged a knife and countered with a flame enhanced punch to the assultant's face. Todoroki nodded like he understood Tsuna's plan while Bakugo shouted, "Don't Boss me around!" before running off with his classmate.
"Iida!" Eraserhead called out, "You have to go and get help!" He bounced around tying up villains while blocking the Quirks of others. Tenya froze up a little before he responded.
"B-But I can be of help here!"
Eraserhead did not have the time to argue with one student. That is when the situation went from bad to worse. A large monster looking creature walked through the last of the Warp Gate's portals. He had a beak shaped face and his brain was showing at the top of his head. His deep purple skin looked to be as thick as a rhino's hide.
"He's here! Nomu has finally shown up!" The leader shouted through the hand latched to his face. He sounded like a child who had just seen Santa Claus.
The newcomer made Tenya even more nervous. How could he leave his Friends and Teachers in a perdiciment like this? "I-I can-"
"Iida!" Tsuna's new commanding voice was almost soothing to his classmates, "I know it is a little scary but we can handle this."
Tenya was still worried, "B-But the gate. If we try to open it it will seal shut. I don't think I'm fast enough!"
Ochaco ran over to Tenya and lightened his gear with her Quirk. Tsuna positioned himself in front of the gate with his right hand aimmed at the gate and his left firing soft Sky Flames.
"Operation X"

Izuku, Tsuyu, and Minoru were still on the yacht surrounded by water and villains. The villains didn't make a move yet which gave Izuku a little bit of hope. They all have Quirks that excel in the water but...
"Asui, Mineta!" Izuku shouted excitedly, "They don't know what our Quirks are. We have the advantage!"
"Call me Tsuyu, I thought we were closer than that..."
Minoru was too busy crying and freaking out to listen to Izuku. Izuku started to mumble to himself with different calulations between himself, Tsuyu, and Minoru. Minoru's Quirk was odd for this situtation while Tsuyu's was almost perfect. "Asui- I mean Tsuyu, what are the extents of your Quirk?"
"Well I have many traits like a frog. My tonuge, and I can secrete an acid like substance from my stomache."
"Right! Mineta?" Izuku looked over to see him crying and rambling about how young they are and how they were up against real criminals! "Mineta! Listen, we need to put our Quirks together so we can defeat these guys."
The Heroes-in-Training had taken too long as the villains started to attack the yacht. One could control the water around himself, flinging spheres of water at the ship, while another threw a harpoon. The villains worked together to open a hole in the bottom of the ship and proceded to flood it, which in turn made Minoru freak out even more. In a blind terror the small teen started to throw the purple balls that his head produced. Some of the balls bounced off the villains while others couldn't be removed whatsoever.
"Mineta! Can you control the balls to stick to others?"
"Y-Yeah..."
"Alright. I have a plan..." Izuku brought his classmates in real close to discuss his plan.

The monster, known as Nomu, seemed to be completely unstoppable. Eraserhead had cancelled out his Quirk but it still elt that he had Super Strength on top of whatever his Quirk could be. The cutom made scarf that Aizawa fought with was useless compared to this monstrosity. Each punch made the long haired Pro nearly faint. But he couldn't, there were too many important lives in his hands right now.
Aizawa was too distracted to worry about just Nomu. Iida was doubting himself, Sawada was handling this better than the teachers, and there still was no word coming from the outside.
"X-Burner!"
Everything changed with that phrase as Tsuna fired a blast so powerful it melted the gate doors. That was Tenya's chance. In a roaring burst of speed, the armored speedster rocketed off into the outside world.
"Mr. Aizawa!" Ochaco and the others shouted in horror. Tsuna look to find not only a monster but other villains start to close in, ganging up on the Pro Teacher. The younf Boss quickly shot over towards Aizawa to help him. Knocking villains away with enhanced punches and burst of flames helped but there was too many. Aizawa was overwhelmed and Tsuna was losing hope fast.
"Tsuna! You better not be giving up now!!!"
"R-Reborn?"
"Keep it up just for a little longer. Your Family is almost there."
Tsuna nodded to himself like that reassurance was all he needed to get back up. "Natsu, let's go." The small lion cub appered in a burst of flames before pouncing on Tsuna's left shoulder. Natsu and Tsuna were more in sync with each other than any of the other students ccould hope to be. It was like Natsu was an extension of Tsuna. The lion cub watched Tsuna's back while he focused on the enemies directly in front of him. Natsu let out a roar, ignited by Sky Flames, sending anyone trying to harm Tsuna into the ground.
With Tsuna taking care of all the fodder, Aizawa was able to focus on Nomu. The monster grabbed the teacher by his face and slammed him into the ground. Everything looked bad until in the distance they saw Midoriya high above the water.

"Deku Shot - SMASH!"
Izuku was high above the lake and yacht while Minoru and Tsuyu were throwing the purple balls at the villains in the water. The flick of his middle finger was almost one hundred fold then he normally does. The words rang in Izuku's memory, "To use One for All, you must clench your buttocks and shout SMASH!"
The blast was powerful enough to create a crater unter the water causing the lake to become a giant drain. Minoru used his Quirk to make the purple balls stick to the villains. They were all clumped together stopping the water from draining. Tsuyu shot her tongue to catch Izuku and she swam the three of them to the shore line meeting up with the other students who stayed away from the more dangerous fight. Izuku saw Tsuna use all of his power for the first time. Everyone was amazed at how calm Tsuna was fighting as well as how powerful he actually was. Sparring with Reborn was nothing like this to Class 1-A, even Izuku's sparring in the mountians was different.
Shigaraki had hust about enough of all of this. This whole attack on U.A. was meant to draw out All Might. The News was always covering him teaching, HE SHOULD BE HERE! The scratching wasn't enough for the young man anymore. He dashed towards the closest student, Tsuyu, and he tried to grasp her face to disintergate the young teen...
But it didn't work.
"Eraserhead..." Shigaraki looked at the Hero pinned under the enormous Nomu. Aizawa refused to close his eyes, no matter how hard Nomu was gripping his head. No Students will be harmed.
"Sensei!" Tsuna was now flying towards the Hero and monster as fast as he could. "Natsu! Cambio Forma!" the lion cub jumped on Tsuna's right hand, "Modo Attacco: Mintena di Primo." Natsu transformed into a silver gauntlet with a blue shield with the Roman Numeral "I" on it. Tsuna charged as much Hard Sky Flames into the gauntlet as he could muster before punching Nomu in the face. The monsterous man roared in pain as the sphere of Sky Flames removed him from Eraserhead.
"S-Sawada... get away." Tsnua looked at his beaten teacher before glaring at Nomu. Natsu transformed back into his Lion-self, perched on Tsuna's shoulder.
"Sorry, Aizawa. I have to protect my friends with my Dying Will."
