3rd person POV
It was a normal day a U.A. High. The class of 1-A was out on the field, training.
"Hey everyone, want to stop for a water break?" Izuku called out.
"Sure!" Ochako replied. Soon after, they were sitting on the ground in a group with Bakugo, Momo, Todoroki, Iida, Kirishima, and Mina. They were chatting about a variety of things, when there was an explosion a couple of blocks away.
"What was that?" Midoriya wondered.
"I suggest we go check it out." Iida said.
"I hope I can fight it!" Bakugo yelled.
Kirishima sighed. "Let's go see what it was."
The group took off at run towards the area the explosion came from. They arrived just as the smoke cleared and saw something completely unexpected. It wasn't some strange villain or a hero that might've been blasted away from a fight, but a man and a teen. The man had pure white hair, glasses, a black bodysuit, and an unknown weapon of great size. The teen had white hair, though not as white as the man's, red stitches all over his body with some in the roman numeral of 13 in his hair, brightly colored overalls, and a strange scythe with corners on it. Then the kid spoke.
"Where am I? Then he looked over at the man next to him and froze in shock. He stared blankly at him then asked,"Hey, I thought you died, what are you doing here sir?"
The man looked over to the teen and started speaking. "Investigator Suzuya, I see you're still the same as always. As for why and how I got here, I do not have the answer to that. After my demise at the battle with the Eyepatch, it was simply dark. I was just drifting around for who-knows-how-long until I saw a light. I went towards it expecting some kind of afterlife, but I found myself here. What about you?"
"I was just raiding the Kaneki family's pantry during their kid's birthday party when I saw a weird light coming out the back door. Of course I had to check it out, so I opened the door and here I am!"
"The Kaneki family?"
"Oh yeah, you died before they got married. Well it turns out that awhile after Haise got his memories back and defeated you, he got married to the S rated ghoul the Rabbit and had a kid. A lot of other stuff happened, but I'll catch you up later."
The class of 1-A looked on at their exchange, dumbfounded. Then the teen, revealed to be named Suzuya exclaimed.
"Hey, my hair reverted back to normal! And now that I think about it, I feel shorter!"
"Maybe they can answer some of our questions." The man said, gesturing to the group of students.
The group was shocked, as the two people hadn't given them any sign that they had noticed them. It was Mina who spoke first.
"Who are you people?"
"I was a Special Class Investigator, Juuzou Suzuya of the CCG, but now I'm a peacekeeper for the TSC." The boy announced. "This man was another Special Class Investigator, though he was the strongest of all of us and considered the boss. He died a few years ago in a battle against a ghoul. His name's Arima."
"What's a ghoul?" Momo asked.
"Wait, you mean you don't have ghouls here?! But you speak Japanese, so we must be in Japan."
"Yeah, we're in Japan, but I've never heard of a ghoul before." Momo replied.
"So, Mr. Suzuya-"
"Juuzou is fine Mr. Broccoli."
"So, Juuzou, what is a Special Class-"
"Wait just one minute Mr. Broccoli, you asked us a question, so we get to ask you one too. So, who are you?" Juuzou interrupted Midoriya again.
"Well for starters, my name is Izuku Midoriya, not Mr. Broccoli. This here is Ochacko Uraraka, Tenya Iida, Momo Yaoyorozu, Bakugo Katsuki, Kirishima Eijiro, Shoto Todoroki, and Mina Ashida. We're students of class 1-A from U.A. High."
"All right Mr. Broccoli, thank you for introducing your friends."
Midoriya sighed and heard Bakudo snickering behind him.
"Actually, before you begin asking your questions, perhaps we should move to a more comfortable spot. Besides, it appears we have company," the man known as Arima said.
The students look around and realized that while they were talking, the rest of class 1-A and some teachers had rushed to the scene, thinking they were under attack.
After the teachers arrived, the group of students explained that they weren't under attack and Juuzou and Arima were escorted to the principal's office, where they explained the basics of their story to the staff and the group of students, but skipped over the details. By the end of it, they people from U.A. appeared to be more confused than before the story.
"So what you're trying to tell me, is that in your world, there are no quirks, things called ghouls that look like people but actually eat them and have an extra organ, and a group of people who use the ghoul's extra organ as a weapon and try to exterminate the ghouls. Ha, what a load of bull." Bakugo exclaimed.
"AHAHAHAHAHAHAHA!!!!" Juuzou started laughing hard, which evolved into creepy giggles.
"Juuzou..." Arima warned.
"Don't worry Arima sir, I won't do anything to hurt the kid." Then before anyone could blink, Juuzou had kicked Bakugo's feet out from under him and used his scythe to catch him, making sure the sharp edge was right next to his neck.
The teachers and students all reacted in an instant, rushing to attack Juuzou and getting ready to use their quirks, but Juuzou easily evaded all their attacks until Midnight tore the fabric on her arm and Kirishima and Uraraka fell asleep. After seeing them pass out cold, Juuzou advised against fighting them. Arima grabbed his arm and told him in a stern voice to calm down.
"Aaawww, but it was just getting fun." Juuzou complained. "And see, I didn't hurt the kid."
"I must apologize for the behavior of my young companion here. He has always been sort of an odd one."
"Haise was always nice to me. He also gave me snacks all the time," Juuzou grumbled.
"Well now everyone, let's calm down and sit. I have a proposition to make, but before that, Mr. Suzuya, you mentioned that you look and feel a few years younger than you were. That's perfect then! How about you and Mr. Arima here join U.A. High?" The principal offered.
Everyone was silent, and then, "HUH?!"
This is Juuzou and his weapon and Arima and his weapon. Ignore Kaneki in the last two pictures.
So, that's the first chapter. If you liked it, please comment and vote. Should I have characters like Kaneki, Touka, Ayato, Hide, Ichika, etc. show up? If you want me to, please tell me in the comment section, and which characters. So far I'm only adding Juuzou and Arima because they're my favorite characters.
