I realised that it's been a while since I updated and I had a rather large part of the chapter done, so this is part 1. As always, feel free to criticize or even make requests. I hope you enjoy!

At last the day had arrived, it was only the day after but that didn't matter to Izuku. He was ecstatic to be going to the USJ. As you probably expected, Rachel wasn't particularly excited, she saw it as another day. Little did she know...

They were welcomed by a hero in a astronaut costume. They introduced themselves as 13. Izuku started to mutter (again) about 13 and Rachel found out from the mumbling that 13 was a rescue hero. They went through all of the situations the students would have to experience during the day and when they were about to get started, a dark purple portal appeared, surrounding them.

Both of the pro heroes there, 13 and , knew this was trouble. 13 tried to use their quirk in secret but was caught. Even when Bakugo and Kirishima landed great hits, the portal remained. Kurogiri used his position to forward the plan. He scattered the students to different areas of the USJ, those areas had a nasty surprise for the students. Kurogiri left some students with 13 so the villains that weren't hiding could have fun as well.

Izuku found himself in the city part of the building, and he looked around and found Rachel.
"Are you ok?" Rachel nodded and they began to find a way out. But this would be a rubbish finale if it was easy. Not even minutes into their search, they heard a bone-chilling laugh. Izuku froze up in fear and Rachel was flooded with relief.
"Izuku, we'll be fine." She whispered to him and he whispered back,
"How can you be so sure?" Rachel couldn't answer before they were found.
"Now, what do we have here?" Izuku was confused, that sounded like Kaachan.
"K-Kaachan?" Izuku stuttered out without turning around. Then again, did Kaachan really laugh like that?
"Who the fuck is Kaachan?" This confirmed it for Rachel so she turned around and her face somewhat lit up when she saw a familiar person.
"Rachel what are you doing?" She didn't answer Izuku. She was both surprised and not. Of course he was the killer, but he was here, in front of her.

"Zack." She smiled, the promise could be fulfilled now, the sweet death that she longed for could now be achieved.
"Huh? Ray, what ya doin' here?" This made Izuku turn around in shock. He had no clue who this 'Zack' guy was, but he knew that weapon.
"That's the scythe that was used in the raids." Zack just nodded.
"Yeah so?"
"How do you know him Rachel? He's a villain." There was only one possibility in his mind and he didn't want to admit it, but was Rachel a villain?
"Don't you remember? I said could only remember jumping off of something with a man." That was another possibility.
"So this is the man?" Rachel nodded and Izuku wondered how a girl like Rachel met this man. He asked that and got,
"It's none of ya fucking business squirt. Now Ray, this a friend of yours?"
'Why would it matter if I'm a friend? I'll die if I don't do something!' Izuku thought as he began to channel one-for-all in his arm.
"Yes he is." Rachel answered and Zack answered with something that honestly surprised him.
"You have friends!? That's so unlike you. Anyway, I'll leave him." Izuku was stumped, why would Zack let him live?
"So Ray, I know I gotta promise to keep. Should we go?" Rachel turned to Izuku, who at this point was more confused than he had ever been.
"It was nice knowing you. Bye." With that they walked down the corridor and Izuku didn't follow, he was spared once so he didn't want to test his luck. Of course he could just punch Zack, but Rachel would be caught in the blast and he didn't want to hurt her feelings. Zack was obviously important to her. So he found the way out by himself.

It was a shitstorm out there. There was this weird bird thing beating up Aizawa and Izuku could see everyone fighting in the different sections. His first priority was helping Mr. Aizawa, he looked like he could pass out at any second. Izuku ran towards the bird while he was channelling one-for-all is his arm. Barely anything happened when the fist made contact. Izuku had only used a small amount to see how strong the bird was so he didn't have to suffer the pain of a broken limb yet. His mind was still racing about the encounter with Zack. What did he mean by "promise"? And why did Rachel say goodbye to him as if she was going to die? Izuku hoped that what he thought wasn't the case. Rachel was his friend so she couldn't die.

Izuku continued to fight the beast and to put it simply, he hoped that All-Might would suddenly appear out of nowhere so he would make it out alive. It was brutal and he would need a lot of help just fighting this bird. That's not taking into account the other villains. On the bright side, Aizawa had a slightly higher chance of survival now. Being too preoccupied with the bird, Izuku didn't notice a blue haired man behind him in the distance.

Back with Rachel and Zack, it was much more peaceful. Their goal was to escape this building and then Zack would kill Rachel. Easy plan and they had done it before. They were running in any shadows they could find to avoid being seen because they might have quirks, but they're weak as hell. If Rachel hadn't noticed the situation that Izuku was in, they would've been out of that building in record time. Zack was astounded when Rachel ran into the battle and even shouted at her in surprise.

Izuku was ready to channel one-for-all in his arm at 100% to try and defeat this monster. The last thing he expected was for the monster to be tripped by red thread.
"Rachel! Just run!" He shouted to her as she ran between the bird and Izuku. She shook her head at him.
"No, we're friends right?" Both of the heroes heard vomiting noises and of course it was Zack. Izuku heard him mutter about this being cheesy. Using the last of his strength, Aizawa used his battered scarf to stall the beast. This gave Zack just enough time to swoop in and grab the two heroes. Unfortunately, Shigaraki noticed what Zack did. He wasn't pleased about that.

So that's the end of part one and fell free to call it dogshit if you want. I don't know when part two will be up but I'm planning on publishing an AOT fanfic. See ya in the next part!
