(Y/n) made it to Union Academy and descended near the entrance. People looked on and saw he was holding a woman in his arms. His friends then noticed this and watched him walk indoors.

Izuki:"Hey, who was that?"

Joan:"Maybe she was the reason he powered up so much."

Ruby:"Let's check it out."

They nodded and followed after him as he made his way to the infirmary. He set her gently on a bed as Recovery Girl looked over her.

(Y/n) turned around and saw his friends looking at him curiously.

(Y/n):"Get the club together. I need to make an announcement."

He walked off without saying anything else which left them even more curious.

And soon his club members had gathered as (Y/n) looked at each of them.

Rias:"(Y/n), why are we here? I thought practice was only on Mondays, Wednesdays, and Thursdays."

(Y/n):"I didn't call you here to practice. I came to talk. The person that made me bleed when we had our first meeting is finally dealt with. Her name is Android 21. Ruby, Joan, and Izuki saw me carrying her to the infirmary. Hopefully I can convince her to join our side."

Kirishima:"Sweet! So that's one problem dealt with!"

(Y/n):"Yep, but there's just one last loose end to tie up."

Asia:"Towa, right?"

He simply nodded

Pyrrha:"How are you going to deal with her?"

(Y/n):"That's the reason why I called you here. I'll be bringing two mentors of mine here."

Everyone gasped and went wide eyed.

Issei:"No way! Some of your own mentors?! Then they gotta be crazy strong!"

(Y/n):"Indeed. Far more than me that's for certain."

He looked at his fist and clenched it and let out a small chuckle.

(Y/n):"I want to have a sparring match with them that you all can witness."

Rias:"Witness a sparring match between three powerful beings? That's going to draw a lot of attention won't it?"

(Y/n):"Exactly. Towa won't be able to resist the power that's being gathered up in one place. And with my mentors at my side we can get the drop on her."

They all nodded and agreed.

(Y/n):"So if one of you may be so kind as to let Ozpin know we'll be borrowing the stadium..."

He began creating a magic circle with a piece of chalk and used his ki to transport himself back to his home world.

Pyrrha:"Rias, how about you and I go?"

Rias:"Right. Let's go."

The two redheads got up from their seats and began walking to the nearest elevator. Everyone else in the club room began discussing how awesome it would be to see (Y/n) going up against some people stronger than him.

Joan:"I wonder what his mentors are like."

Izuki:"Well he told us they were tough as nails and made him push past his limits. My guess is they are wise old people that use their age as a way to hide their strength."

Ruby:"No way! I bet they're huge men about 7 feet tall with bushy beards!"

Joan:"Maybe they're monks that can paralyze you with a single hit."

They kept discussing his mentors' possible looks until Rias and Pyrrha came back.

Rias:"Good news, we have been given permission to use the stadium. But the teachers are going to be watching as well. Let's hurry on up."

Everyone nodded and began making their way there. A few minutes passed by as everyone sat in the front rows and waited for (Y/n). Soon enough, the ring began glowing and (Y/n) stood there with two men at his side.

Ozpin:"So it's true then..."

Izuki:"No way...those look like..."

Sirzechs:"The heroes of old..."

(Y/n):"Everyone! Meet my mentors! Goku and Vegeta!"

Goku waved at them as Vegeta just scowled lightly.

Vegeta:"So you really are the strongest one here, huh?"

(Y/n):"Yep."

Goku:"So there's no one good to fight here? Aw man."

(Y/n):"Chin up Goku."

Goku:"Alright! Mainly because I'm excited to spar with you!"

(Y/n):"Before we do that, let me lay down some rules."

He got in a huddle with them and whispered something and they nodded before getting into different corners of the ring. They all simply stared at each other before making any moves.

Issei:"I don't know why, but the air itself feels tense!"

Kirishima:"No kidding. I can only imagine what those other two guys are capable of."

Yang:"Probably far more then what (Y/n) can do."

Blake:"Even then we might not have seen all he can do."

THOOOM!

The arena's force field activated and blocked flying debris as everyone jumped from the sudden sound. All three guys were in the center of the ring with their fists touching. They soon jumped away from one another.

Ruby:"They were so fast!"

Nezu:"Oh my, and they damaged the ring quite a bit with their first punch."

(Y/n) began walking slowly as he eyed Goku and Vegeta carefully. He threw a punch in the air and a massive gust of wind kicked up and pushed them back while tearing up the ground. They stood their ground and Goku ran right at him.

(Y/n) saw and ran as well. He jumped and aimed a kick for his head, but Goku caught his leg and threw him to Vegeta. Vegeta smirked and got ready to strike before (Y/n) recovered in the air and landed back on the ground. He threw a punch and hit Vegeta across his face. He grit his teeth before tightly grabbing his wrist and pulling him in for a headbutt. The hit landed and (Y/n) groaned in pain before stumbling backwards.

Vegeta:"Come on already! I'm starting to get bored!"

(Y/n):"Come on 'Geets, you gotta work your way up to the fun part. A Saiyan such as yourself should be aware of that."

Goku:"He's right."

Vegeta:"Shut it you clown! If you don't act I'll kick your ass!"

Goku stuck his tongue out at Vegeta which only ticked him off.

(Y/n):"Ooh! Get his ass!"

Vegeta:"That's it! Killing ya both!"

He flew at them and struck them both in the gut and caused them to crash into the barrier.

Ruby:"(Y/n)!"

Joan:"Holy crap that looked like it could kill a person."

Goku and (Y/n) then flew at Vegeta and they all started trading blows that were too fast for any of the others to see. But they could tell it was fierce by the sounds of sonic booms and shockwaves tearing up the arena. Finally, they saw two figures crashing into the ground. (Y/n) simply floated back down to the ring and held a smile on his face.

(Y/n):"Everyone, hold onto your seats. You're gonna see what real power is like."

Goku and Vegeta got up off the ground and stepped onto the ring once again.

Goku:"HRRRAAAHHH!!!"

His hair suddenly went golden yellow and his yellow aura destroyed part of the ring and shook the stadium. The audience shook and nearly fell out their seats.

Vegeta:"URRRAAAHH!!!"

Vegeta yelled to the sky and shook the stadium as well.

Their powers rose drastically and everyone in the bleachers looked scared.

Ozpin:"So this is the Super Saiyan transformation..."

All Might:"They're in an entirely different league."

Everyone looked at (Y/n) who had the biggest smile on his face.

(Y/n): Towa, come on out girl. You know you can't resist all this, but maybe my own power will draw her out.

He laughed to himself before yelling up at the sky.

(Y/n):"LET'S DO THIS! KAIOKEN!"

A red pillar of aura erupted from his body and shot up into the sky.

Kirishima:"There it is!"

Ruby:"Go! (Y/n)!"

His friends and teachers cheered him on as all three fighters dashed at each other faster than anyone could see. But the destruction they left behind was evident.

(Y/n):"Bring it!"

They heard (Y/n) roar before watching Goku crash down to the ground and forming a massive crater. Vegeta took the chance to kick (Y/n) straight down and laughed.

Vegeta:"Haha! I'm unstoppable!"

His victory was short lived as Goku flew up and grabbed him by the ankles. He spun him around and launched him into the atmosphere.

Goku:"Whoops! Don't worry best buddy! I got you!"

He then took after him as (Y/n) got back up and patted the dirt off him.

(Y/n):"Times five!"

His power grew even more before he flew after them. Everyone looked up and watched as clouds started dissipating and constant shockwaves happened. They weren't the only ones watching as Towa finally noticed the spike in energy and went to check for herself. She flew to their location and saw them throwing a barrage of punches and kicks.

(Y/n) stopped and faced her. He was sweating and powered down.

Towa:"So, you brought the Saiyans with you."

(Y/n):"Indeed..."

He instantly appeared before her and she gasped. He threw his hand at her and it landed on her chest. He gave it a squeeze and made her go red.

Towa:"Ahhn~ (Y-Y/n)..."

Goku:"He found her weak spot!"

Vegeta:"No you imbecile! That's our cue!"

Goku:"Right!"

Goku and Vegeta appeared before her and both struck her in the back of the head with immense strength. She went out cold and fell limp in (Y/n)'s arms.

(Y/n):"Well boys, time to head on home."

They nodded and powered down before flying back to Union Academy. Everyone watched as (Y/n) had Towa slung over his shoulders.

Ozpin:"That's Towa then..."

(Y/n):"Yep! And her interference here is all over! We will take her back home so the higher ups can decide her fate."

Sirzechs:"Higher ups?"

Goku:"He means Beerus and Whis, and the Supreme Kai of Time. They're gods basically. Except Whis, he's an angel!"

Sirzechs:"I see. They must be powerful then."

Vegeta:"Incredibly so. Beerus and Whis are far beyond our reach."

Everyone just looked on surprised as (Y/n) just laughed and made the magic circle again and disappeared. Once they were gone, everyone fell back in their seats.

Glynda:"I can't believe it... All along we thought that (Y/n) was incredible, but to think his mentors and actual gods surpass him."

Ruby:"But that doesn't stop (Y/n)!"

Joan:"Yeah! He's a human, but he's managed to fight side by side with those two! He's the best of the best!"

Izuki:"Right! And I'm glad he was here to help us all out!"

Everyone agreed and decided to go back to their dorms for some rest.
