We see Y/n walking down a long hallway of the Gremory family home that is pretty big and a lot more fancy then his as he look around and looking at the paintings on the walls as Rias and her family came up to him looking at a family painting.

Y/n: Huh pretty big family you have there.

Venelana: Indeed. We have been around for a long time.

Zeolticus: Our daughter has told us a lot about you and how you took care of her for a long while.

Y/n: Yeah and she's been with me as well.

Zeolticus: (smile) I appreciate the kindness you give to pur daughter. She could use someone who is has powerful and interesting. I mean a Dark Slayer....what a interesting title.

Y/n: (smirk) But cool as well.

Zeolticus just nodes while Rias is not saying anything which concerned Y/n a bit when he hears someone said.

???: Oh its you.

He turn to see Grayfia and next to her was a young boy as he approaches her.

Y/n: I remember you. Your Rias maid a while ago.

Grayfia: (smile) Indeed. I hope your ready for dinner.

Y/n: (smile) I'm ready for any food. So the kid?

Grayfia: Oh this Millicas. He's my and Sirzechs son.

Millicas: (smile) Hi it's nice to meet you. Your really cool.

Y/n: (smirk) Thanks kiddo. Maybe one day you'll be better than me.

He smiled and soon after they arrived at the dinner hall where they begin to have dinner. Y/n sat next to Rias who isn't saying nothing which Y/n gently grab her hand as a sign to tell her that whatever it might be it will be okay.

Sirzechs: So Y/n tell me how skilled are you when it comes to combat?

Y/n: Well I'm an expert of guns, swords, hand to hand combat and all cool stuff. Oh and I know how to ride a motorcycle bike.

Sirzechs: You ride a bike?

Y/n: Yeah. There is a rule that no one is not allow to ride on it, especially Issei. Last time he ignore my rule he scratched it! Sorry it still pisses me off remembering about it.

Sirzechs: I see. Do you see Issei as a friend?

Y/n: Yeah he's a okay friend but he's sometimes....an idiot. Don't give me wrong Issei is pretty good but he's easily distracted.

Venelana: What sort of things distracts him?

Y/n: I won't say it but let's just say it's something that woman have.

Venelana: I see?

Zeolticus: Still its interesting that two powerful people is within Rias household. Its a surprise.

Sirzechs: Its good that she is adding in some new members to the house hold. It's been awhile she had some new members isn't that right sis?

Rias then gets up and walks off which Y/n now knows something is wrong so he excuses himself and leaves to catch up with her.

Soon he came up to her room as he knock on the door and ask.

Y/n: Hey its me....can I come in?

Rias: Yeah.

He opens the door and sees Rias laying on the bed with her face onto the pillow as he came up to her bed and then sat on her bed. There was some silence and then he said.

Y/n: I suppose its something to do with your brother or father?

Rias: Yeah.

Y/n: Well I'm sorry to not doing anything about it. I never met your family and I don't really know what they are like. I have some clubs but not enough.

Rias: (sigh) Don't blame yourself. I know it's not your fault.

She then sat up on her bed with her pillow wrapped around her arms and covering her lips as she goes on to say.

Rias: They don't seem to understand the work I'm going through. I'm just the youngest child besides Millicas and they always try to embarrass me. I just want it to stop.

Y/n:......Yeah it sucked but.....your lucky that you got a  family. Meanwhile I don't know anything about my biological family. I'm always alone until I became older and start to make a family of my own. Seeing your family makes me a bit happy. True they are sometimes rude but at least they are a good family. I....I kinda wanted that.

Then he felt a touch on his shoulder as he turn to see Rias as she tells him.

Rias: I'm sorry. I didn't realise how your past was so sad. Meeting my parents must have made you excited to what it feels like being part of one. I shouldn't get mad.

Y/n: No its alright. (Smirk) Besides I can't see my princess looking so sad.

Rias: (giggle) You surely do know how to make a girl cheer up.

Y/n: (smirk) Part of my charm.

She giggle once more and then the two lend in and they kissed. They begun to make out as Rias sat on his lap while crossing her legs around Y/n's back and the two go at it.

They let out moans of pleasure as their tongues clash to each other as they let out mre moans until they collapses onto the bed where they make out once more.

Soon we see Y/n on top of Rias as they were done making out and after a kiss they look at each other while breathing heavily as they look at each other for a bit and then Rias give him signs to take things to the next level.

He let's out a smirk and unbutton her uniform as her bra is expose as he gets to the final button. He gently touch her cheek which she begins to suck on his thump and making some sexxy moans as she keeps sucking his thump which Y/n gets heated as he lend over as they were about to go at it once more when they heard.

Sirzechs: I suppose you are full from your dinner?

They look over to see Sirzechs standing at the door. There was silence in the room until Y/n ask.

Y/n: How long have you been standing there?

Sirzechs: I just came in to check but it seems I interrupting you having "fun" with my sister.

Y/n: Indeed I have. You cool about it?

Sirzechs: Of course. You deserve her. Well best be leaving you two be.

He turns to leave but then he stop and then turns back.

Sirzechs: One more thing. Rias remember the thing we talked about.

Rias: Of course.

He nodes and he leaves the room as he closes the door behind him.

Y/n: What was he talking about?

Rias: Best I'll tell you tomorrow. Now where were we?

Then they go at it as moans cane be heard outside of the door as they have a bit of "fun" in Rias bed room.

(Next day)

When Y/n and Asia arrived at the Occult research club we see everyone gathered at the chained up room which Rias releases the chains as Y/n then ask.

Y/n: So we're going to find out what is inside?

Rias: Yes. I believe it is time.

Issei: I really hope it is a sexxy girl in there.

Kiba: Probably not keep your hopes up Issei.

Asia: I wonder what is inside.

Xenovia: Probably a weapons room.

Koneko: Guess one way to find out.

Rias grabs the door handle and then opens it. Everyone looked inside and inside what looks like a normal girls roo, except there is a coffin in the middle of the room rather a bed.

They enter the room and look around as Issei approaches the coffin and he kicks on it.

Issei: Seems like just a empty room. Say why is a coffin he-

???: AAAAAAAAHHHHHHHHHHH!!!!

Issei jump back after he heard the scream while the rest apart of Rias and Akeno are surprised that someone is inside the coffin.

Y/n: Well I don't remember monsters scream like a little girl.

Rias: There is no reason to fear, you can come out now.

???: I don't understand what is going on?

Akeno came over to the coffin and begins to open the coffin while she said.

Akeno: (smile) Don't worry you can come out, it's safe.

???: No I don't want to fome out! The outside is scary.

When the coffin is open they look inside and to their surprise sees a young innocent looking girl who is extremely cute.

Y/n: (surprised) Wow she is super cute! Good thing Lucifer isn't here otherwise she might might hug her to death.

Issei: Hell yeah? A super cute girl! Finally my first girl added to my harem coll-

Rias: The child is a guy.

Y/n and Issei froze for a moment and slowly turn their heads to Rias and then ask.

Issei and Y/n: Wait, what did you say?

Rias: (smile) He may look like a girl, but he is indeed a guy.

Asia: (surprised) Wait so this one is actually a male.

Xenovia: (surprised) That's unexpected.

Issei: Wait? Hey how come you didn't point that out he's a duds man!

Y/n: Don't blame me! Look i may have known Irina is a girl but it's not like I'm suddenly a guy who knows who is male or female! Actually why do you dress up like a girl......what is his name?

Gasper: M-My name is G-Gasper and I like dressing up at a girl because it's cute.

Y/n: Well if everyone is fine then I'm fine....I guess?

Rias: (smile) How's about we come out okay?

Gasper: No I don't want to go out!

Issei: Come on man it isn't that ba-

When he came over and grab Gasper arm, he screamed and suddenly vanishes from sight which they look around and then finds him at the corner scared.

Gasper: (scared) I'm sorry I didn't mean to make you all mad. Please don't hurt me.

Asia: (surprised) Did he just teleported?

Y/n: No that's not teleporting.

Rias: Indeed. He has a sacred gear that can freeze time.

Issei: (surprised) As in he can stop time?! Oh man just imagine what that ability can do if I have it.

Y/n just sighs and then walks over to Gasper as he kneels down and reach out his hand to him.

Y/n: Don't worry kiddo. We're not mad at you, we're surprised. How's about we come out and we can introduce each other properly, okay?

Gasper:....O-Okay.

Gasper gently take Y/n's hand as Y/n looks into Gaspers eyes and he was hit by something that he is familiar with. He doesn't know why but he felt like Gasper is just like him when he was young.

He shakes off that thought and take Gasper out of the room so Rias can explain more information about Gasper and why he was in a locked room for who knows how long.
