3 days have passed and you waited in your hideout for Sirzechs to give the answer

Alex: (Y/n) if he says no are we still going to kill his sister and peerage anyway?

(Y/n): That's the plan

D.C: Even if he does say yes don't you think they'll betray you?

Talon: Remember Boss they do have the Red Dragon emperor by their side. Would they really give him up so easily to win a rating game

Ace: Would it start another war?

(Y/n): Those odds have crossed my mind countless times, but another war starting I highly doubt it.

Raynare: Everyone is still trying to rebuild especially Devils and Fallen Angels like us.

The Magic circle appeared on the floor and Sirzechs came through

(Y/n): Do You have your answer?

Sirzechs: My answer is yes...

(Y/n): And you're fully aware of what happens after I help your whore of a sister. I get to kill the Red Dragon emperor and take his sacred gear correct?

Sirzechs: Y-Yes..That is correct...

Talon: Looks like the almighty Devil King isn't so almighty after all? *Shrugs*

(Y/n): Pleasure doing business with you.

Sirzechs: That Rating game is in 10 days. You guys will meet Rias' and her peerage later.

Sirzechs Disappeared going back to the underworld.

Grayfia: So how did that go?

Sirzechs: He thinks he's going to kill the red dragon emperor under my watch and he's in my sister's peerage is which means he's even more important. When he thinks hello kill him we'll ambush him and kill him and his team

Grayfia: You sure that will work?l my dear?

Sirzechs: It has to. For Rias' future and the future for all devils.

-TimeSkip-

Rias and her peerage were walking up the mountain to get to their training spot

Akeno: Visualize Issei you're almost there

Rias: C'mon you're so close

Issei: I'm coming! Gosh this is so tiring!

Koneko: Om Your left

She bumped issei on the way up and he almost fell but he stayed up

Issei: Phew

But he heard Kiba's footsteps behind him

Issei: Don't say it. Don't you dare!

Kiba: On your left

Issei: Ahh!

Kiba pushed Issei making him fall on his back and he was frustrated and tired

Issei: AGH! What are they carrying?! Bags of feathers or something!?

Rias: *Chuckled*

After a few minutes and Asia using her Twilight healing on Issei Sirzechs came along with Grayfia

Rias: Hello brother what's going on

Sirzechs: I bring along some help for your rating game.

Rias: And who's helping

He snapped his fingers and (Y/n) and his team landed behind Sirzechs

Rias and her Peerage: (Y/N)!!!!?

Sirzechs: He said he would help you smd guaranteed I looked no one is stronger than him

Issei: *Gulps*

Sirzechs: Alright kids have fun

He disappears

Black: Is that the Pervert?

(Y/n): Yeah that's him

Black: And those are the whores...aren't they.

(Y/n): Mhmm

Black: Can I kill them now.?

(Y/n): No not yet

Akeno: (Y-Y/n) I-it's you again.

Asia: (Y/n)!

You raised your hand

(Y/n): Before we get to training I just want you to know that...

Rias/Akeno/Asia/Koneko: 'Please don't hate us! Please don't hate us! Please don't hate us!'

(Y/n): I hate you all of course besides Kiba

The girls looked down in defeat

Ace: Wait Boss, if we're going to be training them I want to test their skills.

(Y/n): Why?

Ace: They seem weak, I want to know how hard this is going to be.

(Y/n): *Sighs* Very well

Ace then walks over to Rias and her peerage with his hands in his coat pockets.

Ace: Hey pervert try to give me a fight on this one, unless you want a repeat of last time. How is your stomach by the way?

Issei: I'm going to enjoy this.

Ace: Me too

The white haired fallen angel says as he knees Issei in the stomach, knocking him down. Kokeno then lunges at him, but he kicks her in mid air and she is sent into a wall.

Ace: Alioop.

Kiba then charges at him and slices at his neck, but Acero doges the blade.

Ace: I'm getting the strangest feeling of deja vu

He comments before shattering the blade with a kick.

Kiba: Ain't that a kick in the hea-

Kiba is interrupted by a kick in the head by Acero.

Akeno: Aren't you just cute?~

Acero: Bitch I'm adorable.

He says as he flies behind her and kicks her in the back.

Acero: I'm bored, you're all boring me.

(Y/n): Wow, he really is holding back. He hasn't even thrown a punch.

Angela: That and he's been holding back his strength.

Rias then sends a ball of energy at him which hits him dead on, making him fall to the ground.

Ace: Maybe I was a bit to hasty to judge them.

He mutters to himself before getting up

Ace: Alright I'll give one of you a free hit, but be sure to not use it to quickly or...

Issei: Boost

He yells before punching Acero in the mouth, the force of which sends him back a few feet

Ace: Your gonna regret it.

He says as he kicks Issei in his side with a crack, and he is thrown into Rias. Kokeno then grabs him from behind in a full nelson and Akeno sends lightning into him.

Akeno: Begone you bastard.

*Bang*

A gunshot goes off as Akeno is shot in the side, and Kokeno is seen beaten and bloodied with Ace scuffed and his coat burned.

Ace: Well you succeeded in destroying my favorite coat.

He says as he jumps over and kicks into Akeno, he then turns his attention to Kiba and Asia.

Ace: Honestly out of everyone here I don't really have anything against you kiba but the others only cheated on (Y/n), which is a bitch move, isn't the same as trying to kill him. So, give up now or taste dirt.

Kiba summons his sword and flies and unleashes a flurry of strikes at Ace who starts dodging every strike.

Issei: How is missing so many?

Rias: Because he's aiming at where he is instead of where he will be.

Acero then grabs Kiba's head.

Ace: I'm about to take your breath away.

Kiba: What?

Ace: No homo.

He says kneeing Kiba in his stomach, and Kiba falls to the ground coughing up blood. Rias then sends a wave of destruction at Acero, who side steps it.

Ace: Really? You just saw me dismantle your entire peerage and you thought that would be a good idea.

He says pulling out a gun from his pocket and shooting rias in the shoulder.

Issei: YOU BASTARD!!! BOOST!!!

The red dragon emperor yells in a rage punching Ace back, he then flies over and uppercuts him into the air before kicking him down to the ground.

Issei: DRAGON SHOT!!!

He says as a bullet of energy explodes at Ace.

Ace: I'm impressed, behind all that perverted mind and horrid personality there's a real fighter

Issei: And behind all that snark is a dead man

Ace: Issei, you couldn't fathom the amount of dead men behind me.

Raynare: Should we do something?

Black: No

(Y/n): If I had to guess, Issei is currently more powerful than when we fought last.

You says as Issei throws Acero into the ground.

Issei: Now that might of not done much, bit damn did that feel good.

Ace: Oh my, do I detect an iota of pride? I guess you and your bitch of a king really are meant for each other.

Issei: That snark isn't going to save you when I'm taking you apart. If you hadn't noticed I literally have you backed into a corner.

Ace: And don't think I don't appreciate the effort. By a wide margin you're packing more of a wallop than these harlequin babies ever did. However, you will never. Ever. Defeat me.

Issei: THEN WHAT DO YOU CALL THE LAST 5 MINUTES?!

Ace: Pity.

(Y/n)'s team: *Bursts out laughing*

Rias: Don't worry, he's just playing you

Issei then charges at Acero who catches his punch and elbows Issei in the neck. He then flips over him and grabs his arm and breaks it.

Rias: Correction, he's been playing you.

Issei: How?

Ace: Because you green, an amateur. You claim to he a fighter when you've barely ever fought in your life. Plus your reliance on that gear is pitiful, there are other dragons and you can barely use yours. Even I can use it better.

Issei: Come again?

He says as his arm gets a tattoo of a hyena and he gets a copy of Issei's sacred gear.

Acero: Balance Breaker

He says as he is covered in red armor.

Acero: "My name is Issei, I'm a pervert and I have zero redeeming qualities. Someone love me" See your not special.

(Y/n): See anyone can do it

Acero says as he drops the gear and the tattoo disappears as well.

Issei: That's a terrible impression

(Y/n):: But not inaccurate.

Ace: Not stop embarrassing yourself and get down here.

He says as Issei flies down.

Issei: I give up.

Issei mutters as Acero flies over to (Y/n).

(Y/n): So?

Ace: There worth training.

(Y/n): *Sighs* Very well

You look at the rest of your team

(Y/n): Gather around gang. Now make sure to share your toys, don't leave my sight and bring me the bodies

Rias' peerage: *Gasp*

(Y/n): But more importantly have fun!
