Ever since you and your brother found out the ssj2 and 3 transformations, you both have been doing nothing but train, eat, and workout in order to get to those forms. It has been 3 months since they've started training and neither one of them wants to quit and lose .

AT SCHOOL.

Y/N: Guess I'm eating lunch on the roof again. Nice and quit.

You secretly climbed the side of the school building and just ate the big lunch that you made.

Y/N: This is so good!

You didn't waste any time and just ate like it was the end of the world for you. After you ate you started to read, but you felt a random source of power appear near the school.

Y/N: What kind of energy is that? well, whatever it is, it belongs to a high ranking devil for sure. I should probably go check it out.

You slide down the school pipe and after using your senses, you sense that the source of power is coming from the ORC clubhouse.

Y/N: I hope Rias isn't doing anything stupid!

You rush over to the Orc room and kick the doors open, and when you kick the doors open, you see a group of people you've never seen before.

Y/N: Who the hell are you people!

BEFORE YOU BARGED IN.

Rias: It seems like today will be another great day.

Akeno: It does seem that way.

Rias: This may be random, but have noticed anything different about Y/N?

Akeno: In what way?

Rias: I've been able to sense his power for a while now, and back when I first felt 3 months ago it blew me away, but now it feels like It's 3 no 5x what his energy was.

Akeno: He must've been doing some training then. How do you think he came across that power in the first place?

Rias: That is a possibility.

Rias then felt a source of power and then an orange magic circle appear on the floor, then she saw a tower of flames.

Rias: Not him again!

???: Ah, the human world. How nice it is to live in a beautiful place such as this!

 Rias: What are you doing here, Riser?!

Riser: I'm here to check up on fiance.

Rias: I'm not your fiance, Riser!

Rias: Still cold as ever. You haven't changed one bit, my dear.

Issei: Who are you? and why are you her fiance?

Riser: Who is this, Rias?

Rias: He is Issei Hyoudou, and my pawn.

Riser: Well you better tell your pawn to have some manners while speaking to me.

Issei: What do you mean by that?

Riser: I'm Riser Phoenix of the Phoenix clan.

Issei: And I should know who that is?

Riser: You really are a lower class devil if you don't know one of the noble devil clans.

Issei: What was that?!

Issei summons his sacred gear and gets in a fighting stance.

Riser: You dare pick a fight with me?!

Riser starts to light some flames in his hands.

*BOOM*

Y/N: What's going on here- Who the hell are you?!

Riser: Rias who is this disrespectful child?

Y/N: Name's Y/N, and who are you calling a child?!

Riser: Rias, don't tell me that you still have less than 10 pieces.

Rias: So what if I do?

*SNAP*

Riser: I have a total of 15 pieces.

You see a magic circle appear and then saw a group of 15 girls come out of the ground.

Y/N: Okay who are they?

Riser: They're my peerage. Have you not heard of a peerage? and you call yourself a devil!

Y/N: Okay 1: I have heard of a peerage, and 2: I'm not a devil!

Riser: Now you're recruiting humans, Rias?

Y/N: You got a problem with me as a human, huh?!

You knew Riser didn't know you were a saiyan, so you decided to play along with being a human.

Riser: Humans are the problem that we devils have to deal with. You make most of our lives hard.

Y/N: Then answer me this. Can a weak human do this? HHAAA!

You power up and cover yourself in your dark aura.

Riser: You're more than I took you for. Want to make a deal?

Rivel: What are you doing, brother?

Riser: How'd you like to join my peerage? you can have everything you want and do whatever you want. No one could stop you.

Everyone was surprised at the offer Riser made you, but you just chuckled.

Y/N: You know for being a high ranking devil. You're not to smart. You can take your offer and shove it!

Riser: You dare say that to me? show some respect when you speak to me.

Y/N: You gonna make me? flame brain!

Riser: Why you!

Riser lit his hands on fire and you took a fighting stance getting ready to fight, but another magic circle appeared, and you both see a woman wearing a maid outfit appear.

???: There will be no fighting here, Riser!

Riser: Very well, Grayfia. Oh yeah how is Sirzechs doing?

Grayfia: Sirzech is his usual self, doing paperwork.

Riser: He hasn't changed.

Grayfia: Rias, you have to marry someone soon. You can't just deny marriages.

Rias: I choose who and when I marry. I don't care if you're my brothers queen!

Y/N: Wait "marry" can somebody fill me in here?

Grayfia: And who might you be?

Riser: He's just a lowly human who knows about us devils!

Grayfia: One who takes good care of himself as well.

Y/N: That sure didn't answer my question.

Grayfia: Rias is being forced into a marriage and you can guess who.

Riser: Do you have a problem with that, Y/N?

You went silent for a bit and closed your eyes.

Y/N: I can't believe the words that are coming out of my mouth! You're damn right I do!

You fired back and gave Riser a deadly glare. 

Grayfia: Do you object to the marriage?

Y/N: Take a guess!

Grayfia: Sorry, but the only way to stop this marriage is by doing a battle.

B/N: Well then. Why don't we fight for it.

Everyone turns around and you see your brother leaning against the door with his arms crossed.

Y/N: When did you get here, B/N?

B/N: A while ago.

Riser: Who are you?!

B/N: Names B/N. It's not my pleasure to meet you.

Riser: You've got a big mouth. What can you two do against my entire peerage?

B/N: Oh I don't need to fight. He will.

You see B/N point at you.

Y/N: Why only me?

B/N: I want to see how long you last against a high classed devil.

Y/N: I'll bet he won't last 5 minutes against me!

Riser: You think you can beat us? HA!

Y/N: I want to make this more interesting. I'll fight you one on one.

Riser: Very well, but I want to make a catch.

Y/N: Catch?

Riser: If I win you become a member of my peerage and I marry Rias as planned.

Y/N: What if I win?

Riser: If you win, I'll resign the marriage, and grant you one wish.

Y/N: Interesting, but I want to change one little thing.

Riser: And what might that be?

Y/N: Instead of me being a part of your peerage, the loser. Dies.

Riser: What?

Y/N: You heard me. The loser dies. Is that too much for you? are you afraid of dying.

Riser is being hesitant before answering.

Riser: I'll agree to the loser dying request. Are you okay with your brother doing this?

B/N: You should be the one who should feel okay. I saw how hesitante you were when he asked you.

Riser: I was just taken aback at the request that's all.

B/N: Sure.

Grayfia: Very well. The conditions are set and the loser of the fight will die.

Riser: Better practice on your last words, Y/N!

And just like that, they all disappeared and you and your brother turned to look at each other. After looking at each other you both burst out laughing.

Y/N: I might kill him by mistake.

B/N: He'll be surprised when they find out who we truly are.

Rias: Why are you doing this, Y/N? the first time we met I helped Issei try to kill you.

Y/N: To be perfectly honest. I don't really know.

Rias: I will never understand you.

The two brothers use their instant transmission and teleport back to their house. Y/N was getting ready for his battle with Riser.
