The Arcobaleno Vigilantes (KHRxBNHA)

USJ (Build up)

     It was the day of the USJ trip and one man of the name Yagi Toshinori was ready to go out and teach in it... That was if his time limit didn't run out. He was in a rush to get to the center when he suddenly felt himself deflating, so he turned his direction to rest in the teachers lounge, unaware of a little note in his pocket warning him about an eventual attack.

"Line up by your I.D. numbers and fill the seats in an orderly fashion!" yelled a certain blue haired teen, only to sink in rejection when they got on the bus and realized that it had the different seating arrangements than he thought. When they were seated Tsuyu asked Midorya a question about his quirk and how it resembled All Mights (Which he quickly dodged around). After that everyone on the bus got into small talk until Aizawa announced that it was time to get off the bus and head into the USJ center. (A/N: Im so sorry this isn't specific rn)

As they walked in all of the students looked around the simulation joint in childish wonder and glee, it radiating even more when they saw the Space Hero: 13 when they entered. Too emerged into what the Space Hero was saying they didn't notice eyes on them from different places in the joint. That was until a black portal appeared revealing villains, and the eyes that were on them whole time let themselves be known.

Midoriya Izuku was having a good day so far. He didn't have to deal with the stress of being the class president, made friends, and he's going to train at USJ to become a hero like he's always wanted to. He was all ready to learn and fight for his dream, until a black warp gate opened up in front of everyone in his class. He vividly heard Aizawa's voice ring out, telling them to 'stay back' too focused on the villains appearing in front of him. 

Watching as Bakugo and Kirishima lunged at the villain in front of them, then suddenly disappear made him flinch in worry, then when he saw it surround him and his class and also swallow him and the others. He thought he was done for, well until Ausi came and saved him from the water, then got the three of them onto the boat (Midoriya, Ausi, and Mineta). Once they were all situated, he decided that it was time for him to be a hero and step in to help. About to explain why they needed to do it to the others he was cut off by a voice... a very loud voice that definitely didn't belong to any of the students,

"Oi oi oi, What are you kids doing here? kora!"

The Arcobaleno were preparing for the ambush. Now, they didn't know everything that was going to happen because of the late invitation to join. They were underprepared though for this situation, but they knew they could prevail, because they were the worlds strongest seven, and the knew that. As quick as he could after the announcement Verde hacked into U.A.'s computers again and pulled the blueprints for the USJ facility so they could see what they had to work with. 

Once that was done they all gathered in their living room for debriefing and plan making. The main people that coordinated the plans in the Arcobaleno were Lal, Reborn, and surprisingly Skull (He wasn't the main strategist in the Carcassa for nothing). Reborn was mainly there for finalizing and confirming plans. Sitting in the room and looking at the blueprints they let the experts prepare for the upcoming battle.

All throughout the night they were planning on ways that could help and the ways that they could let the students do their own things, after all in Reborn's words 'we just can't interfere with the students learning, can we~' and the fact that he was polishing a gun as he said that didn't make any of the Arcobaleno want to interfere with what he thought should happen with the students. 

Even though they knew they could handle whatever situation, didn't mean that they had to if heroes didn't show up, so they decided to leave a little warning in one of their favorite heroes costumes, and if that hero didn't realize then that showed for how great heroes were at observing things (But that was just their opinion). After a full nights rest (or what they considered a full nights rest) they were ready to go and fight.

Gathering their belongings they all left the base prepared. The first part of the plan was actually getting into the USJ building. Really, it all wasn't that hard with the security system down. Once they all got in place though was when the real show started. Though their was one thing that they didn't expect,

"Oi! Shitty Dragon why are you doing here?"

"Are those drones?"

 "Whoa it's Le Immortal!"

"Oi oi oi, what are you kids doing here? kora!"

"Chaos"

I'm sorry about this chapter I was mainly trying to get it to build up but then hit ended up sloppy and I don't really know how I could have made it more interesting. The next one will be better tho I promise (I hope). The first few arcs will go by quick in this story and then it will get more story during one of the more later arcs
