We see Kiba walking through the halls of Kouh academy while talking to some female students as they were just talking what a day they are having when Y/n and Asia approaches Kiba and a group of female students as Y/n ask Kiba.

Y/n: (smile) Yo Kiba can I borrow you for a bit?

Kiba: (smile) Sure thing Y/n.

The female students make theie leave after saying goodbye to Kiba and once they were gone Y/n tells Kiba what happened last night to which Kiba looked a bit surprised and tells Y/n.

Kiba: Well I never see Rias act like that in my life. She's usually calm no matter what.

Y/n: Huh weird. Still that maid who appeared in my room said about "The Phenex family" whoever they are.

Kiba: I think I've heard about them before. They are a very powerful family within the underworld and according to what I've learned, there is a man named Riser Phenex who is the Head leader to his house hold.

Asia: He sounds like a powerful person.

Y/n: (smirk) Not to me. So what dose he have in his peerage?

Kiba: Well let's just say he has a lot of girls within his house hold.

Issei: You mean he also has a harem?!

They jump a bit when Issei appear out of nowhere which Y/n slap Issei at the back of the head while he tells him.

Y/n: Damn it Issei are you trying to scare us!

Issei: Ow! I can't help it when I heard another person has a harem! This is just great, first you, then your friend and now this other guy!? Whose next?! (Tears) My life sucks!

Asia: I'm worry tgat maybe this Riser guy may try to marry Rias.

Y/n: (smirk) I know Rias is a tough and smart person, I'm sure she'll tell this Riser guy to fuck off and that will be it. Besides, she's nearly an adult, she's allow to make her own decisions whatever she wants. It's not like her parents are gonna make her marrying Riser. Not for a million yea-

(Later)

Rias: My parents request to marrying Riser Phenex.

They were at the Occult research club as Rias tells them this news which stunned them a bit.

Y/n: (thought) Well fuck me then.

Issei: They can't be serious?!

Rias: I afraid so. They wish me to marry Riser so both families will be stronger within the underworld.

Y/n: Well that's stupid. They can't make that decision.

???: Oh they can and I will marry her.

Suddenly a magic circle open with flames coming out of it as a man blonde hair while wearing a red jacket with a white shirt underneath it comes out of the circle along with the same maid from last night.

Issei: So he must be Riser.

Akeno: That's correct.

Riser: (smile) I hope you'll exited about our marriage my dear Rias.

Rias: I told you not to call me that and didn't I tell you not to come here.

???: Your parents allow Riser to come here to meet your peerage.

Issei: Look at her! Whose she?

Akeno: That's Grayfia, she serves the Gremory family for years and she's the wife of Sirzechs Lucifer.

Issei: (smirk) Well she's a hot maid.

Y/n: Yeah don't get any ideas.

Koneko: Yeah pervert.

Then Riser approaches close to Rias's desk as he lend his arm onto his desk while get close to Rias as he tell her.

Riser: (smirk) This will be a great day for both of our families once we are married. We will be the most strongest devils in our lives.

Rias: I never care about that and I surely don't care about you either.

Riser: You may not care but I do. I very much care about you and our future and the future of our family.

He gose to place his hand onto Rias when Y/n sees how she didn't like it so he was the first to tell Riser.

Y/n: Yo how's about you remove your disgusting hands away from Rias.

Riser looked over and glare at Y/n as he stood up and ask in a angry and annoyed tone.

Riser: (anger) And who the hell are you? Aren't you apart of Rias's peerage?

Y/n: I'm just a guy who is working with Rias and the others. Your suppose to be the strongest devil ever? Ha! Your nothing but just a pathetic person who thinks he is powerful.

Riser: (anger) What did you just say?!

Y/n: (smirk) I can already tell you haven't faced anyone who is stronger then you and only saying that because your family is powerful. I bet the only reason why you wish to marry Rias is because you can just use her intelligence and power so you can make yourself powerful.

Riser: (anger) You dare to mock me! Don't you know who I am!

Y/n: Um let me see? Riser......Riser.......Riser.....Oh! I know! Riser Chicken, that's your full name right?

Riser: (anger) How dare you!

Grayfia: That's enough! It seems both sides ain't gonna agree on anything. My I suggest an alternative way to settle this?

Rias: Sure.

Grayfia: I suggest the Rating Game. If Rias wins, the wedding is cancelled. If Riser wins, the wedding will begin.

Issei: Um what's the Rating Game?

Akeno: It's a competition between two devils with a peerage. It's similar to Chess where both sides have to knock off the king of the match.

Y/n: (smirk) In short, a battle arena so we can beat the crap at Riser Chicken here and win.

Riser: (anger) You better regret your words because I will burn you alive!

Y/n: (smirk) Sorry but I'm not in a menu for your chicken restaurant.

Riser: (anger) Why you-!

Grayfia: Riser!

Riser turne to Grayfia while he growl angry at Y/n and tells Grayfia.

Riser: Fine, I'll accept the challenge.

Grayfia: And Rias?

Rias: Of course. Our house hold will win for sure.

Riser: We'll see about that.

Once that but Riser and Grayfia leave the room as Rias let's out a sigh and looks over to Y/n and was not mad that he was rude to Riser....but impressed that he did.

(Later)

In order for them to get stronger for the Rating Games, they take a long walk to a large mansion where they will stay there for 2 weeks as they train for the Rating Game. They begin their training with Kiba, Y/n and Koneko doing well on the training while Issei needs some few lessons by Y/n to master his scared gear in hopes for Issei to last longer in battle.

Akeno and Rias also train while also making some food with Y/n helping the two girls out in some days. They kept training for a week and we see Y/n at the open field while holding three target disk which he throw at in the sky and once they were lined up, he quickly shoot his one shot pistol and took out all three disks.

He smirked to himself when Akeno voice can be heard behind him.

Akeno: (smirk) My My, such a good shot.

He turn to her as she approaches him with a smirk on her as he reply to Akeno.

Y/n: (smirk) This gun may fire one shot but I've found useful ways to hit my targets.

Akeno: (smirk) How interesting.

Y/n: Yep. So how is Rias doing so far?

Akeno: She's doing alright. She might still be worrying about the Rating Game.

Y/n: Why? Judging by her intelligence, I think we have a chance.

Akeno: True but Riser is a complete different story. He has more peerage on him with some stronger then one of us. She may worry we might lose.

Y/n: (smirk) I'll tell her not to worry and we'll be fine. We'll win for sure.

Akeno: (smirk) Agree. I love how your so cool about this and we're thankful that you wish to help us.

Y/n: (smirk) It's my pleasure.

Akeno smirked even more, always love his attitude and his personality. Soon everyone was inside the mansion and having some dinner when Y/n noticed Issei looking at Rias and the others girls with a pervert look on him. He stomp his foot on top of Issei which hurt as he turn to Y/n, seeing him just eating, pretending he didn't do nothing while Issei gose back to eating.

Y/n noticed the worry look on Rias face about the Rating Game. So after dinner  everyone heads to bed and get some sleep except for Rias who is outside and near the fountain while looking at the night sky when Y/n walked up to her and stood next to her.

Y/n: Ain't this a good night huh?

Rias: Guess so.

Y/n:......I know your worrying about the Rating Games but don't worry, we'll win this.

Rias: Maybe.....but there is this small thing inside of me telling me that we might lose. Sure I am smart and powerful but when it comes to Riser and his peerage.....I'm not too sure we have a chance to win.

Y/n: Sure we can. Numbers doesn't matter. Intelligence outmatches any army if you put your head into it. True Riser has more peerage then us but we've been through things that a small group of us can't beat but guess what, we did.

Rias: You think so? You think we can win this?

Y/n: (smirk) Sure we can. Look forget what your family says  to you, your a person no matter if you are a devil, an angel or hell even a human. You and you, you have ever right to make your own decisions even if you were forced to by anyone even by means your parents. I don't care who your true love belong to just as long your love is in the right place and not some asshole or pervert. You love whoever your heart wants you to fall in love with.

Rias is surprised by his words as he turn and heads inside but when he was about to open the door, Rias called out to him.

Rias: Wh-What if I told you I have a crush with someone me who has a dark armor but has a good heart behind the armor?

Y/n was surprised but smirked and then tells her.

Y/n: (smirk) Then I bet he loves you the same way as you love him. Goodnight Rias.

Rias blushes a bit as he head inside while Rias continues to blush, her heart beats even more as she realised that he dose love her which madd her smile.

Soon after Y/n arrive back to his room where he jump into bed and let's out a sigh as he shut his eyes, trying to get some sleep when he felt someone on top of him so he open his eyes to see Asia on top of him, wearing her Pajamas as she tells Y/n.

Asia: Sorry I.....couldn't get some sleep.

Y/n: (smile) That's good Asia. You wanna sleep with me?

Asia: Actually.......I was wondering if we could.......you know....do the "thing?"

Y/n: (little blush) Oh. Well......are you sure?

Asia: Yes of course! I wish to make love to you and I can't hold this anymore. I want to do it right now because.....I love you.

She then lend in and kiss Y/n on the lips. This made Y/n blushed in surprised as Asia stars to kiss him on the lips while making some cute moans while she continues to kiss him.

Soon Y/n slowly allow her tongue to enter to his mouth and soon after he kiss her right back as the two make out as they wrap their arms around each other while they make out even more.

(Lemon start)

The two roll over with Y/n on top of Asia as the two continue to make out with Asia let out some cute groans as Y/n stick his tongue within her mouth and they continue until the two stop to catch a breathers.

Asia was turned on as she looked up at him with love in her eyes while Y/n find it very adorable which he lend down and start to kiss her neck which made her gasp and moan even more.

Asia: (moaning) Oh Y/n~! That feels soo good~! Ah~!

He continues to kiss her neck while his hand slowly move and grab one of her breast which made her moan even more as he continues to squeeze her breast while kissing her neck for a bit until he stop and Asia unbuttoned her buttons and show her breast to Y/n which she said.

Asia: (blush) I-I'm sorry they are not as big as Rias or Akeno.

Y/n: (smirk) Your perfect either way.

And so they took off all of their clothes, leaving them completely naked as Y/n starts to sucks one of Ash's breast while squeezing the other which made Asia let out some moans as she grab hold the blanket while Y/n continues to look on her breast while squeezeing the other one.

Asia: (moaning) Please more~! Please more~! Aaahh~!

Soon her milk came out of her breast which Y/n drinks them all up and once that he looked up at Asia to see her panting and looking very adorable then ever.

Soon they turn over with Asia on top of Y/n with his dick into her vigina as the two make some moans while Asia gose up and down while Y/n was holding on her waist while she gose up and down.

Asia: (moaning) This feels soo good~!

Y/n: (moaning) Very good~!

They go faster and after a minute the two let it out as the two let out a loud moan. They breath heavily after that and then later Asia gives Y/n a blow job as Y/n is laying in bed while Asia licks his dick and soon starts sucking his dick which made him moan while Asia continues to suck his dick.

Y/n: (moaning) Oh shit I feel it! There it comes~! Aaaaaaaaahhhhh~!!!!!!

Asia drink it all up and remove her mouth from Y/n's dick as she crawl up to him and then lay next to him. She cuddle with Y/n as he shut off the lamp and pull over the blanket.

(Lemon ends)

The two were laying in bed naked with the blanket covering them with Asia cuddling with Y/n as she falls asleep while Y/n is looking up at the ceiling while he turn to Asia, smiled and kissed her on the forhead as he slowly falls asleep and the next day they will continue on training for the Rating Game.

(Meanwhile)

A door opens as a mysterious man enters and there was Riser and his peerage as the man walked up to him as Riser tells him.

Riser: They have this person by the name of Y/n L/n. At the Rating Games, I want you to kill him and make sure he is dead for sure.

The man let's out a small chuckle and after that he reply to Riser.

???: Sure thing.....I'll get the job done, for a price.
