I did a pretty good job on this chapter cover.

Y/n: How long have they been doing these experiments on you?

Lucy: ... 19 years... Ever since I was just a little girl.

Y/n: ...

Y/n grabbed her arm and started pulling her towards the exit. Lucy tilted her head.

Lucy: What are you doing?

Y/n: Getting the hell out of here. Ironwood or the one that captured you also did this to other girls too. They're with my friends now.

Y/n saw a closet near the door, he opened it to find some clothes in there. He took them out and handed them to Lucy.

Y/n: Here wear this.

He threw her the clothes. She nodded and quickly put the clothes on.

About 10 minutes later....

Lucy was now in the clothes that Y/n gave her.

Y/n: There, that's better now le-

He was then cut off by almost getting slashed with a sword but luckily he dodged. He turned his head to see a man in White armor.

Hakumen (Basically Jin growing out of Yandere mode for Y/n and becoming the hero he should've been)

Hakumen: I am the White Void, I am the Cold Steel, I am the Just Sword, with blade in hand i will reap the sins of this world and cleanse it in the Fires of Destruction! I am Hakumen, the end has come!!"

Y/n: Shit.. This might be bad..

???...

Sitting in a table, drinking a cup of tea. Rachel watches from her Mansion that both Y/n the Bloodedge and Hakumen have made contact with each other. She takes a sip of the cup and puts it down on the table.

Rachel: Oh my, this will be interesting..

Intro...

Back Y/n...

Y/n grabbed his Aramasa and the blade was filled with dark aura.

Hakumen: Dark One, this will be your end.

Y/n: Heard that one before, you masked freak.... Bring it on!

He turned his head towards Lucy. 

Y/n: You get him from here while I get him up close. 

The pink haired female nods

Y/n ran towards the masked man to go for a swing but was blocked. The man grabbed his collar and slammed him on the ground. 

Hakumen then jumped away as he saw invisible hands coming straight towards him. He then slammed his sword on the ground causing rumble to come up. He then grabbed one of the rocks and kicks it at Lucy.

Lucy: ?!

The incoming debris was heading straight towards her. She summons more vectors from her back to grab the incoming rock.

Lucy: Rgh!

She breaks the rock and throws it back to the armored man.

Hakumen: Hmph!

The man dashes forward and brings his sword in the air. With a swing of his sword, he slices the rock in half and punches Lucy in the face sending her to the wall. Y/n slowly gets up and looks to see that the girl was on the wall.

Y/n: Damn that asshole!

Y/n grabs Aramasa and jumps in the air. He drives his sword down towards the armored man and shouted.

Y/n: Belial Edge!

Hakumen turned his head to see Y/n coming at him. He couldn't react in time and Y/n managed to land his attack on him which sent him to the ground.

Y/n: About damn time... Ark, he hit me pretty hard before. My wounds aren't healing as fast as they usually do. What kind of fucking sword is that?

He gets up and runs towards Lucy, he noticed that she was injured.

Y/n: Are you alright Lucy?

She shook her head as she pointed at her arm, he looked down to see it bleeding.

Y/n: Shit it looks pretty bad. You should leave while I take care of this son of bitch.

Lucy: You know you can't take him on by yourself....

Y/n: That's because I haven't activated my powers yet...

Lucy: Hm?

Y/n: Don't worry about it... You should go bef-

???: Die!

Y/n turned around to see the white swordsman right behind him about to cut him with his blade. Y/n grabs Lucy and missed the sword slash but what the two didn't notice was that Hakumen reeled his fist. 

Hakumen: No escape!

Hakumen pushed his fist with enough force to send Y/n and Lucy in the air crashing into multiple floors.

Player 1

Y/n the Bloodedge Lose!

With Rumi and the other girls...

The place was filled with bodies on the floor. Rumi wiped some sweat off her face as she exhaled.

Rumi: Looks like we're done here.

Hades: My for someone who is a hero, you sure went crazy with these soldiers.

Ramia: Agreed, I mean like when you broke someone's neck with your legs. Pretty impressive I must say.

Baiken nodded in agreement as she seethes her blade into the holder.

Baiken: Right, now we should try to get out of here bef-

Suddenly they hear a loud crash, the girls turn around to see Y/n on the roof, he spat out blood.

Y/n: Guagh!

The girls: Y/n!

He slowly turns to them. He was about to say something until he saw Hakumen jumping at him and Lucy and punching them through the ceiling.

Rumi: We have to help him!

The girls nodded. A weapon forged on Hades hand, it was a huge sword.

Hades: Alright, let's do this!

Back to Y/n...

Y/n held Lucy tight as he was punched so hard the two were forced out of the factory. The two crashed down in the front gates were Heroes and huntsmen were taking care of some of the villains.

Y/n: Shit!

???: Y/n!

Hearing a familiar voice he turns his head to see his former classmates. He groaned in annoyance.

Y/n: Damnit, all of you are here too!

Yang: We came to stop you from causing all of this destruction.

Xenovia: And to capture you.

Bakugo: And we're gonna kick your ass if you resist!

Y/n: I don't to play with a bunch of little kids right now, I have to l-

Crash!

Y/n: Oh my fucking God...

He turns his head to see Hakumen landing on ground.

Hakumen: This is the end Dark One!

Issei: Whoa, who's that?!

DDraig: I don't know but he's really powerful that exceeds ours by a lot.

Issei: What?!

Ruby: Look at his sword too! So cool!

Suddenly more people jump in the fray as Baiken and other girls stand around the injured Bloodedge.

Y/n: Girls, you're all here!

Ramia: Whoa, you took a beating. He must be really strong!

Y/n: Y-Yeah... He's really damn strong.

Baiken: Let us take care of the Union students for you.

Y/n: Thanks a lot. These fools still won't learn to leave me the hell alone.

Ramia: Wohoo, hopefully they'll be a better challenge than the Atlas soldiers.

Yang and Xenovia growled as they now know that Y/n has more girls with him.

Xenovia: We won't let you get away this time, we will bring him back.

Yang: We will stop you!

Y/n gets up from the ground with Lucy in his hands. He gives Lucy to Rumi.

Y/n: Protect her, alright.

Rumi nods her head

Rumi: Alright, I will.

Y/n: Thank you.

Y/n's right arm started shaking but continues to stand. He stares at Hakumen with anger in his eyes.

Hakumen: Dark One, you will not see the next day!

Y/n: Shut up already and just fight!

The Wheels of Fate are Turning...

Rebel 2...

Action!

The two rush towards each other and clash swords. Hakumen goes for another swing but Y/n rolls out of the way. Y/n grabs his sword and was about to go for a slash but it was blocked. He then grabbed Hakumen by the face and dragged him on the ground,  he then picked him up by the neck and punched him in the gut. 

Hakumen: Tch.

Hakumen kicked the spiky haired teen in the gut letting go of his neck. The white void then punched Y/n in the face making him slid on the dirt.

Y/n: Grk!

Y/n wiped his mouth and saw that there was blood. He gripped his hand. Suddenly his body began to glow as the ground shook, stopping everyone from fighting to look at him

Blake: Y-Y/n?

Kiba: W-What the hell is going on?

Izuku: W-What's happening?!

Pyrrha: This feels like an earthquake!

Hades: Y/n's power is rising immensely.

Ramia punched IIda on the face then turned her head back at Y/n

Ramia: Oh wow! Y/n is glowing!

Y/n: I didn't want to do this but...

Y/n brought his right arm up by his face. The red shell on his glove opened up as a red light shined the area.

(Say the lines everyone!)

Y/n: Restriction 666 released, deploying the dimensional interference imaginary magic circle....

Y/n clutched his right arm. Gust of winds blew the area.

Baiken: T-This wind!

Hakumen: So this is Y/n the Bloodedge's full power.

Y/n yelled out loud.

Y/n: RAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHH!

The ground cracks more and more as Y/n's power began to rise.

Play Rebellion!

A symbol forms in front of Y/n

Y/n's Crest

With Rumi...

Lucy's eyes opened to see Y/n.

Lucy: Hrg...

She looks down to see Rumi carrying her.

Rumi: Nice to see you awake.

Lucy: Who.... Are you?

Rumi: Names Rumi Usagiyama or the hero Miruko.... Actually I think I'll change my name to Juri or something... Hmmm

Lucy: You're a... Hero?

Rumi: Yep buuut on this occasion, I'm helping Y/n. He heard that people were doing some experiments there and wanted to check it out. He found those two in test tubes.

The bunny girl then pointed down below. Lucy looked to see Ramia and Hades fighting the Union students.

Lucy: What's happening to Y/n?

Rumi: I don't know but it looks dangerous.

Lucy: ...

Back to Y/n...

His right arm shined as the spiky haired boy continued to yell.

Y/n: Blazblue.... Activate!

Y/n looks at Hakumen.

Y/n: Here I come you son of a bitch!

Y/n dashed towards the man as a black aura surrounded his arm and yelled out.

Y/n: Hell's Fang!

With the other arm the black beast came from the ground surprising Hakumen.

Hakumen: What!?

The beast engulfed his entire body. Y/n smirked as pulled his right hand and bringing out the claws of the beast

Y/n: Let Darkness Consume You!!!!

Y/n uses his Seithr claw and starts crushing the armored man.

Hakumen gets launched into the building as Y/n's arm turns back to normal.

Distortion Finish!

Player 1:

Y/n The Bloodedge Wins

Y/n stands as he pants heavily as everything went silent. All eyes were on him.

Y/n: Hmph.... The fuck all of you looking at?

Ramia applauded.

Ramia: Very Stylish!

Hades nodded her head.

Hades: Mhm that power that you have sure is impressive, I wonder what else about you is impressive about you~

Baiken: Shut it fire breather!

Y/n exhaled.

Y/n: Now's not the time to do this... We need to leave.

Momo: Sorry but we aren't going to let you escape here.

Y/n: heh, figured you'd say that, Baiken!

Baiken moved her right shoulder to the ground and a huge cannon came out of her arm. She fired it creating a smoke screen making everyone cover their eyes. Y/n and the girls jumped on the roof. The four continued jumping on roofs to get away from everyone.

Hagakure: Hey! They are leaving!

Coco: No they aren't!

Coco's suitcase turned into a mini-gun and she fired dust bullets the Y/n and the group.

Hades: Freeze!

Hades fired an ice beam at the students and they jumped out the way.

 With Rumi....

Rumi and Lucy see Y/n and the rest of the girls running towards them. Rumi looked at the wrist band to see that the teleportation finally recharged.

Rumi: Guys, the recharging finished! Let's go!

Y/n: Right!

Y/n grabbed onto Ramia's hip, making the black haired female surprised.

Ramia: Oh my, bold indeed~

Hades: Ramia, you lucky gal!

Y/n opens up the teleportation device and a white light shines down on them.

Y/n: Heading Back now!

Y/n pressed the button and they all disappear from the area. What they failed to notice was that they were being watched.

???: Y/n the Bloodedge, interesting~

???

Somewhere else...

In a round table filled with big chairs, a female with white hair and a bunch of others were watching Y/n make his escape. These were all the League Of Villains and Salem's group of minions.

Salem: Y/n the Bloodedge.... Certainly a fascinating man.

AFO (All For One): He certainly is, and that group he's with also seems like he would be a fine collection to have.

Salem nodded her head.

Salem: Agreed, having him at our side will help us get closer to world domination.

AFO: Not only that but we can get rid of those heroes and huntsmen that Union academy are training.

Cinder: Mistress Salem, what should we do?

Salem: Observe him, make him warm up to you. Take Emerald, Mercury and Neo with you too.

Cinder bowed.

Cinder: Yes Mistress Salem.

Shigaraki: What should we do, master? 

AFO: Keep doing what you normally would, and if you see Y/n the Bloodedge... Try to persuade him to be on our side.

Shigaraki: Of course sir.

AFO: Alright then, meeting over... You all can go now.

Somewhere else...

A girl in a orange sweater and a hat sat in front of the TV with sparkles in her eyes.

May

May: Johnny! I think I found the perfect person to add to our crew! And he's totally a cutie!

A man with a big hat and weird clothing walked into the room

Johnny

Johnny: Let me guess, it's that Y/n the Bloodedge fellow again ain't it?

May: Sure am! He looked so cool fighting that white armored guy!
