The Day Of the USJ Attack.

                     "Alright class... All of you shut up and listen." The teacher said, entering the room. Class 1-A immediately ceased all conversation. It didn't take long for them all to figure out that their teacher, the pro hero eraser head, meant business. However they all took note that he looked more stressed than usual.

                     "Mr. Aizawa, you seem more active than usual." The class vice president, Momo Yaoyorozu said. Most of the class nodded in agreement. Aizawa scowled at the statement and just sighed.

                      "Yes, I am, and it's because I have news for this class." Everyone immediately began murmuring until Aizawa glared at them again, making them silent once more.

                     "I am announcing that U.A is getting their first ever transfer students from Europe." Everyone only showed looks of confusion. Transfer students were somewhat common but none were given from Europe. Aizawa must have guessed what they were thinking, as he explained more.

                     "I know it may not seem exciting, but these kids... are unique..." Everyone gave a look of confusion and curiosity.

                      "What do you mean by that, Mr. Aizawa?" The class president, Tenya Iida asked.

                      "Yeah they're just foreign hero course students, what's so odd about that?" Kaminari asked, fist bumping his friend Hanta Sero. Hearing this made Aizawa twitch a little reflecting on past memories when he finally spoke up again.

                      "I am telling you all this because they're quirkless." Bakugou, who was leaning on his chair, nearly fell over at he said. Everyone stayed silent for a brief moment before they all burst into laughter, only to cease at Aizawa activating his quirk.

                     "Listen. I know how ridiculous it sounds, but I can assure you, these guys are not to be taken lightly." Hearing this made Bakugou scoff.

                      "What the hell are you on teach? Quirk less nobodies are always weak." Bakugou said pridefully. He hadn't forgotten about Izuku and was slightly worried about him when All Might began training him. He wouldn't admit he felt bad for him, but he still had to be put in his place. 

                       'It doesn't matter, that little runt is probably dead for all I know' He thought. 

                       "How's that possible? They're the ones with the disadvantage." Ashido asked. Aizawa tensed up at this question, before regaining focus and turning towards his class.

                       "... I have a history with their leader." Aizawa said bluntly, confusing the students. "No more questions. Get your costumes on and head to Ground Alpha." Everyone nodded in unison and dismissed.

                       "It doesn't matter now. Go suit up and meet at the buses, today we are going to the USJ." He said, to which the students nodded. 

Time Skip

                    Class 1-A was on their way to the USJ on a bus while Aizawa sat in the front, reflecting on past memories, especially the ones of HIM. Aizawa swore that he was the scariest person that he ever met, considering his quirk didn't even work on him. If he is capable of nullifying quirks, then he could be the biggest threat the world has ever seen. If his suspicions are correct, he will be coming to UA. He doesn't know his motive, but knows it cannot be good. He feels a tap on the shoulder and turns around to see the class president telling him of how the bus has stopped at the destination. He shrugged off his sleeping bag and joined his class at the way in. 

Time Skip

                  When they all walked in, everyone was shocked to see dozens of people lying on the ground. 

                     "What the hell happened here?" Kirishima asked, sounding almost impressed. Most of the bodies were not moving, but a few were still struggling to stay awake. Aizawa told the kids to stay back while he jumped to one of them, he grabbed him by front of his shirt and began interrogating him.

                   "Who are you? What are you doing here?" He asked angrily. He could already tell these men were villains, thugs at least. However, Aizawa was shocked to feel the man shaking, as if he were traumatized.

                      "H-He told us that there would only b-be students and a teacher here... n-n-nothing more." Aizawa was confused at his statement.

                      "What're you talking about?" Aizawa demanded to know. The man only looked him in the eyes with the worst look of fear you could imagine.

                      "Demons..." He said, and with that, the man fell unconscious. Aizawa sighed in disappointment before he heard the entrance open, and looked to see most of UA's faculty, including All Might and Thirteen. They too developed a disturbed look when they saw all the bodies.

                       "Does anyone know what happened here?" Nezu asked. Only for Thirteen to step forward.

                       "Like I said sir, the USJ was breached by two unknown groups of people. They started fighting each other when I tried to call the mainland, only to be cut off. I snuck out and met with you, and this seems to be the aftermath." The principal nodded at her explanation.

                        "It seems then like one side beat the other." Nezu said, only to be cut of by Thirteen.

                         "That's the thing, sir. One side was way outnumbered, there were only about six of them, and they looked like teenagers." Everyone's eyes widened. 

                         'How was that possible?' They all thought. It was then that Aizawa sensed something. He looked over to see the trees from the forest zone rustling.

                          "Looks like we're about to get our answer, someone's coming." He said. Everyone looked where he was and they all saw a black blur emerge from the trees. The man landed on the ground right in front of everyone. He was a large and tall man for someone his age. He was wearing a black trench coat with a body harness that held eight sword like objects. He had very spiky black hair as well as black lightning shaped sideburns. What everyone saw was a very menacing looking man. He looked around at all the bodies before facing the students and teachers.

                          "Where's the leader of those low lives?" He asked. He locked eyes to helmet with Thirteen, who shuddered. Bakugou began letting tiny explosions out of his palms.

                          "WERE THE ONES WHO SHOULD BE ASKING YOU QUESTIONS! TELL ME WHO YOU ARE OR I'LL KILL YOU!" He shouted angrily only for the man to put his hands on two of the swords. 

                            "If you get in my way, I'll eliminate you." He said calmly. This irritated Bakugou even more, and his explosions only grew bigger. 

                         "Fine by me, other shitty hair." By now he looked just as hostile as the man. 

                         "Young Bakugou NO!" All Might shouted. The two were about to lunge at each other when someone new interfered. 

                         "Hold on, Levi." All of a sudden, several more black-clad figures appeared next to him. They were all sporting their variation of a black trench coat.

                         "You don't get to hunt them by yourself." A tall man with a green side part of hair with an orange fur coat said. 

                         "Share your prey. Shi-Shi-Shi." The blonde kid wearing a tiara said. 

                         "It looks like the situation's changed, the school teachers and the gross students are here." A boy with green hair with a large frog hat said. "Those three guys ditched us due to Levi's stupidity." The dark haired man, now known as Levi, scowled.

                         "VOIIIIII!" A man with long, silver hair yelled. He pointed a sword at the group and waved it threateningly. "Where is the trash with the blue hair?!" He asked, only to get murmurs of confusion. He then scoffed before putting his sword down. "Speaking of which..." He said turning to his associates. "Where in the hell is that damned boss?!" He shouted at them. Only to receive no answer. "That asshole destroyed his earpiece again and now I can't find him." He turned towards the students again. 

                       "I can't believe we transferred to this damned school..." He muttered. Shocking everyone there. 

                       "WHAT?! YOU PSYCHOS ARE THE TRANSFER STUDENTS?!" Bakugou yelled angrily. 

                       "Damn right, trash. We are the most powerful hero students in Europe, and we are all quirkless. So don't think about looking down on us!" The  silver haired man yelled. He everyone's shocked faces. "Heh." He said, before he felt a firm hand on his shoulder. An all too familiar voice spoke out.

                       "Move." He said, and the silver haired man moved out of the way. Everyone got a clear look at him. He was a tall boy, had a spiky hairstyle with several beads, feathers, and an animal tail adorning it. He was wearing a white collared shirt with a loose black tie. He had his trench coat on his shoulders as well as black trousers paired with a set of black combat boots. The most striking thing, however, was his face. He had dull green eyes and two dark spots on his face that looked like scars. All Might's and Bakugou's eyes widened, as well as Aizawa's.

                       "It's you..." Aizawa spoke. "I never thought I'd see you again... Xanxus." Everyone gazed at him only to develop an intense sense of fear. The man's aura only screamed hatred and fear. Everyone, teachers and students alike froze in fear, unable to move their bodies. He looked with cold eyes at the explosion quirk user.

                        "Katsuki Bakugou..." He said in a deep, scarred voice. He raised his left hand, which emitted an orange ball of fire. It glowed brightly, blinding his subordinates, who looked nervous as well.

                        "Boss, you're going to start with that? Here?" The green haired man asked, stepping back.

                        "Are you trying to kill us too?" The silver haired man asked, trying to cover his eyes from the light. Aizawa's eyes widened.

                        "Everyone! RUN!" He shouted. He knew it was too late though. 

                         "Die."
