After your "Sparring" Session with Todoroki and Bakugo, the three of you walked out of the Professor's office, you and Bakugo were covered in ash as Todoroki was somehow clean
Bakugo: Nice going you idiots...
Y/N: How is it our fault?!
Todoroki: You were the one who attacked us out of nowhere, Bakugo...
You went to the ballroom to get washed up and put on a clean pair of clothes when you saw Issei flirting with Ashido who was somewhat into it.
Y/N: You're making a big mistake ashido...
You dug into you bag and began to look for some spare clothes when you saw a small capsule at the very bottom, you grabbed it and risked opening it inside,
you pressed the button on top and Chucked it to the ground before a brand new set of Saiyan Armor came out.
Y/N: I remember this!
Flashback
You were snooping around the capsule Corp building looking for Vegeta because you wanted to spar, You eventually wandered one of Bulma's many labs, she was working on some sort of blue powder stuff with Monaka from the Universe 6 Tournament.
Y/N: Hey Bulma, have you seen Vegeta anywhere?
Bulma: Oh hey there Y/N! I'm not very sure where Vegeta is, he's always away from home...
Y/N: Oh, well thanks anyway!
You were about to walk away when Bulma called your name and brought you to a halt.
Y/N: Need something?
Bulma: I was going to give this to Vegeta but he already has a new set of Armor, Him and Goku have new outfits so you might as well get one too, right?
She handed you a set of Black Saiyan Armor as you looked at it, it was made of the same material as Vegeta's old Armor.
Bulma: It's been decked out with Capsule Corp exclusive technology!
Y/N: Technology?
Bulma: Yeah! First off there being an option to activate a force field around you that makes any projectile smaller than you bounce right back to where it came from!
Y/N: That can actually really come in handy!
Bulma: Right?
She began to get excited that you took a liking to her newest invention, you began to examine it more and found out that it was expandable.
Bulma: Oh Right! This Armor, like all previous versions before it, can stretch to almost any size!
Y/N: Sweet!
Flashback End
You looked at the Armor and examined it again, you began to think about all of your friends back at home.
Y/N: I haven't worn it once yet...Well!
You went to the washroom and got changed into the Saiyan Armor, everyone else was getting ready for the Tournament since the sun was beginning to go down.
Kirishima was looking for you since he was all prepared and didn't know what to do in the meantime, he approached Yang to ask about you.
Kirishima: Hey Yang, do you know where L/N went?
Yang: No clue, he tends to disappear like that...
Suddenly Nora jumped in between the two of them and shouted.
Nora: I Know where he is!! He went to the washroom to get changed!!
Kirishima: Where did you...how do you...never mind...
Suddenly the Washroom door opened up and you stepped out in your new armor getting some people's attention.
Y/N: What up guys?
Ruby: WOOAAH...! THAT'S SO AWESOME!!
Kirishima: Wow L/N! Great outfit! Is that what you're wearing to the Tournament?
You nodded with a grin on your face.
Y/N: Yep! A good friend made it for me!
Midoriya: Woah! He looks like an actual pro hero!
Koneko: Rad...
Suddenly the Professor opened the door and stepped inside.
Professor: Alright everyone, it's time to head to the Tournament! Be ready! We have no idea what kind of fight it will be!
With that you all grabbed the things necessary and headed out, you all went to the front of the academy to see a very large green pad on the ground.
Jaune: What's this for?
Professor: It's what we'll be using to get to the Tournament and back.
Momo: What? Where exactly is this Tournament going to take place?
The professor gave you all a blank stare before speaking up.
Professor: The Null Realm...
Y/N: What?! The Null Realm?! How is any form of technology going to take us to a place that exists outside of the Multiverse?!
Professor: I have my ways, now get on everyone!
You all stepped onto the Pad and as soon as everyone was on, it began to glow bright green.
Jaune: U-Uh...Just how fast does this...
He was interrupted when you All warped to the Null Realm in a matter of seconds.
Jaune: ...Thing Go...?
Professor: We're here!
Jaune: Wait...WHAT?!?!
You all floated above the stage that you were all too familiar with.
Y/N: Woah...Deja Vu...
Tsuyu: Do you know this place, L/N?
Y/N: Yeah...It's where a Tournament Of Power went down a little while back...
Blake: Tournament Of Power?
Y/N: It was a fighting tournament where the 80 warriors of the multiverse including myself were gathered to fight in a winner takes all Battle Royale...
Rias: Hm...if adversaries from the multiverse were gathered, why weren't we invited?
You then spotted some people standing on the stage, you pointed out to the Professor.
Y/N: Sir, There's other people down there!
Professor: I know, let's go see them.
You all began to descend as everyone began to notice the people.
Issei: Wait, That looks like...
Rias: No doubt about it...
Midoriya: No way...that's...
Ruby: What's he doing here?!
You all landed on the stage and began looked to see the other people.
???: Well, It's good to know that you're alive and well...
??? 2: Indeed, I was thinking something grave had happened to you all.
??? 3: It's good to see you my little sister.
??? 4: Yes, it's been a little while.
