You were walking home from A Friends House at Night as you were just whistling A Little song when suddenly you felt A Dark presence and you began to get scared.

Y/n: Weewoo... Weewoo... Weewoo... Wewoo...

You then saw A Figure with A Pair of Crow Wings!

Y/n: AAGH! WEEWOO! WEEWOO! WEEWOO! WEEWOO! WEEWOO! ACK! GAH!

You were Impaled through the stomach, as you fell to the ground nearly in death, the Man standing above you smiling.

???: Well It Looks like You're still alive, yet Barely. I guess I'll have to finish you off now.

He smiled raising the spear again but he heard A Voice behind him.

???2: Stop.

???: Who says so?

Rias: I said so, Rias Gremory of the Gremory Clan and You are Touching my Servant. Now Back away from him, before I beat you to death.

???: So You Know what he is Capable Of?

Rias: I do.

???: He has A Sacred Gear?

Rias: He does.

???: Our Intelligence is right. We'll be back.

He then flew off as Rias looked down at you trying to check our your wound.

Rias: Fufufufu, I Guess I have to heal you again.

You then woke up this time to your Yandere girl Alarm clock as you woke up and you were on the Floor.

Y/n: Huh? When did I get home? Why am I on the floor? AND WHY AM I NAKED!?

You then tried to cover up anything indecent with your hands as you noticed Rias in your bed Naked.

Y/n: Oh Rias is Naked in my bed....................................................................... WAIT, RIAS IS NAKED IN MY BED!? HUH!? WHAT!? WHY!? HOW!? HUUUUUUUUUUH!?

Just then you heard your Mom marching upstairs clearly A Little pissed off.

Mom: Y/n I didn't hear you come home last night! You Better explain yourself, young man!

Y/n: OH GOD!

Rias Just got up with no Urgency whatsoever.

Rias: Hnnnngh... Is it Morning?

Y/n: RIAS! TAKE THIS BLANKET AND- WOAH!

You Tripped and your face fell directly into her Boobs!

Just then your door was slammed open by your Mom!

Mom: Y/N L/N YOU HAVE SOME EXPLAINING TO- H-Huh?

Rias: Oh Hello Ms. L/n, I hope we're not bothering you. I took Y/n Home last night and stayed here for the Night.

Mom: Oh... Okay...

She then ran downstairs with A Series of Loud thuds!

Mom: Oh My God my Precious Baby Boy is having Sex! Should I give him the talk!? His Father's not here so he can't! He literally roped himself, ACute girl! Should I expect Grandbabies!? Oh My God Oh My God!

Rias: Good Mom.

Y/n: Rias-Sama what are you doing here?

Rias: Well I found you last night, and I healed you. How is that wound?

You Looked down and it was gone with only A Bruise left.

Y/n: I-It's good... How did you-?

Rias: I healed you. It would have been fatal for any Normal Human but you truly are something else. It's Like you have some Good Genes in you.

Y/n: Yeah, I got Genes!

Rias: Well I saved you.

Y/n: So Why are you here, and what did you do?

Rias: Right, I almost forgot to say. My Name is Rias Gremory and I'm A Devil. I'm also your Master Now, Y/n L/n~ May I Just call you Y/n?

Y/n: HUH!? W-WHAT!? EEEEEEEEEEEEEEEEEEEEEEH!?
