Makarov: It's been a few days, you all are healed up. So I will be organizing the fighting festival today.

Erza: Who will fight?

Makarov: I was thinking everyone who wants.

Y/n: I want to face Juvia, Lucy and Mira.

Erza: Are you sure? They aren't strong enough to beat you, you know that.

Y/n: I want to see how strong they are at full power. I want to see their true potential.

Lucy: I want to stay alive. Thank you, but I'll pass.

Ten minutes later

Natsu: Lucy come on, you are stronger than this!

Erza: Even I know it Lucy, you aren't using all your power.

Lucy: (Heavy breathing) Y/n is too strong, I can't even get close to him!

Y/n: Lucy get your mind together and stop doubting your strength!

Lucy: If I want to beat you then I have to concentrate. Star Dress Leo Form! (Lucy attacks Y/n with swift kicks)

Y/n: Finally, you are braking your shell Lucy!

Lucy: Regulus Kick! (Hits Y/n on his face making him flip)

Y/n: Not bad. Now it's my turn, God Dragon's Destruction Fist!

Lucy: Oh no! (Evades it barely) This was too close.

Y/n: Seems like you're finally understanding it Lucy, the art of dodging.

Lucy: Of course. I had you as my teacher. (Lucy's and Y/n's fist collide, as a shock wave forms)

Natsu: Is Lucy able to stand up to Y/n now?! Is she really this strong?

Erza: No Natsu she's not able to stand against him, he's testing her and checks how strong she is. Can't you see how effortless he moves?

Gray: Erza's right, if you remember his fight against Irene then it's obvious to me.

Natsu: You are right, he's playing.

Y/n: You got stronger Lucy I can sense that.

Lucy: I know that, thanks to your training and constant fights. (Y/n hits Lucy making her fall of the ring)

Y/n: However you still have lots to learn, but you can manage fighting alone. I would say S class requests should be possible for you now with the help of another mage. 

Lucy: Really? Did I get this strong! (Y/n helps Lucy up)

Y/n: Of course, you are Lucy you fought good no doubt. Well done.

Lucy: I lost, well I didn't expect to win anyways. (Lucy and Y/n leave the ring)

Mirajane: Erza we will fight now!

Erza: Of course She-Devil Mirajane. (Erza and Mirajane look at each other in an evil way)

Y/n: So You both will fight at full power, that means Mirajane's Alegria form vs Erza's Scarlet drive.

Erza: Not quite, I will beat her with my Nakagami Armor.

Mirajane: Take over vs Re-quip, what's stronger... We will find it out now. (Smirks)

Irene: This will be a really cool battle.

https://youtu.be/BZUKQavWH00

Erza: You know Mira some call me a demon or a monster as well. Re-quip Nakagami Armor!

Mirajane: You aren't a demon like me Erza, Take Over Alegria! (Erza and Mirajane attack each other)

Y/n: This battle will end their rivalry against each other in one way or another.

Natsu: (Scared) I will never be able to beat Erza if she's this powerful.

Bahamut: I know who wins this battle.

Erza: It has been more than eight years since our rivalry started Mira, you always tried to make me angry and when Y/n showed up in the guild you always said that he will be my boyfriend and that I should go to a doctor or something. (Hits Mirajane)

Mirajane: So what? I was right, you even held hands with him two weeks after that he joined. (Mirajane kicks Erza in the back)

Erza: (Angry) That happened because I was angry and wanted to leave the guild to go on a job! (Erza and Mira headbutt)

Mirajane: (Angry) It looks like you are as stern as ever, ugly! (Blocks an attack)

Erza: You have lost your bite Mira, you aren't as strong like you used to be so that's why I'm going to win this you punk!

Y/n: (A cold shiver runs down his back) So much anger and brute force, they really are two devils.

Mirajane: I wouldn't be so sure if I were you. (Mirajane and Erza fire a powerful magic spell at each other)

Makarov Can you see who won Y/n?

Y/n: (Shocked runs to Erza) Erza, Mirajane are you able to stand up?

Erza: Don't come closer. (Stands up)

Mira: (Lays on the ground) Looks like I lost Erza.

(Stop music)

Makarov: So Erza keeps the title as strongest female mage.

Y/n: Juvia its your turn now.

Juvia: I have to face you?!

Y/n: I'm the only one who can get you to use your full potential.

Gray: Juvia, show him how strong you are! I believe in you.

Juvia: I will do my best Gray-sama. (Juvia and Y/n enter the ring)

Y/n: Show me all your power Juvia!

Juvia: Water Nebula! (A powerful blast hits Y/n)

Y/n: This isn't your full power, show me all you have!

Gray: Come on Juvia show him your true power!

https://youtu.be/-lfHkm-XPws

Y/n: (Y/n aura starts to darken and he goes into his destroyer form) Juvia there is only one way you can show your true power! (Gray appears in front of him and Y/n stabs him)

Erza: What the hell Y/n?! Why did you stab Gra...(Someone covers her mouth)

Irene: Keep quiet Erza, he has a plan and Gray is fine.

Y/n: Your only way of getting all out of you is trough anger Juvia! Show your true power, release it!

Juvia: ...Gray...-sama. Y/n how could you hurt my GRAY! (Juvia's energy starts to rise immensely, she dashes forward kicking Y/n in the gut making him fly back) 

Y/n: This is the power I have been talking about Juvia, you have the power of the ocean in you, an unstoppable force of nature. (Juvia kicks Y/n again)

Juvia: I will make you pay for hurting my Gray!

Y/n: This is something I had to do. (Hits Juvia) Fight me Juvia of the Great Sea!

Somewhere else

Gray: (Amazed) Juvia is this strong! She can hit Y/n and make him go on the defensive.

Lucy: Of course she is, it's because of you.

Y/n: You have shown your true power now.

Juvia: My true power is my Gray, only because of him I can fight you.

Y/n: (Kicks Juvia) I didn't think that I had to power up at all when fighting you Juvia, but you lost as I had expected.

Juvia: Gray-sama, why did you hurt my Gray-sama!

Y/n: I didn't... (Juvia hits Y/n with a powerful magic attack pining him to a wall)

Juvia: Stand up Y/n and fight me!

Y/n: It looks like you have.... (Juvia upercuts Y/n making him fly back)

Juvia: I'm not done with you Y/n!

Y/n: I'm not gonna lose to you. (Juvia and Y/n headbutt each other)

Juvia: I'm gonna beat you for hurting my love!

Gray: Juvia I'm here, he did this to make you unlock your true power. It was an illusion Juvia.

Juvia: (Looks at him) Gray-sama... you are well. (Runs to him hugging him tightly)

Y/n: I'm sorry for doing it like this, but I had no other choice.

Gray: It's fine I'm unharmed.

Juvia: I forgive you Y/n you meant it in a good way.

Erza: Now that the fight is over, Y/n are you impressed of the three woman.

Y/n: Yes I am. Lucy, Juvia and Mira you all are good fighters no doubt. And Mira I wanted to finally set an end to the question who of you two is stronger.

Erza: I think you just made it worse Y/n. Mira we will fight another day again.

Mira: I can't wait for it Erza.

Y/n: God damn it!

Bahamut: Son, their rivalry will never end it's fate for them to be rivals and you can't change it in anyway. At least you tried.

Irene: Let's get back into the guild and celebrate this battle, right my sweet daughter? (Pats her)

Erza: Yes mom.

Inside the guild

Natsu: Y/n I want to fight you again here and now!

Y/n: You really think that you have a change to hit me? (Natsu attacks Y/n, but slams his head into a wall)

Natsu: I was so close.

Happy: You call flying into a wall close at hitting Y/n?

Frost: He's so delusional.

Irene: I accept everyone who wants to fight me in battle, but be aware I'm stronger than my sweet daughter. (Pats her head)

Erza: Mom stop doing this!

Y/n: So we will have our sparing matches at my home Irene.

Irene: I thought that you will say that for training purposes.

Erza: ...
