Y/N: "You are going home for the summer for training and you want me to come too?"

Sona: "yes. I would like to see your capabilities. And it's time you met my parents."

Y/N: "alright so how are we going to get to the underworld then?"

Sona: "Rias is using her family train and offered us a ride."

Y/N: "I was kinda hoping for a highway..."

Sona: "why?"

Y/N: "AC/DC!"

Sona just shakes her head in disappointment And Y/N just laughs.

Time skip on train

Y/N pov

Y/N: "this is acutely quite nice. I guess I shouldn't go off of what the bible says... it's very one sided isn't it."

Sona: "I'm glad you are enjoying yourself Y/N. we should be arriving soon we should probably go say hi to Rias and her peerage and thank them again for the ride."

Y/N: "your right sona! That's a great idea. Although koneko will probably kill me on sight."

Sona: "what for?"

Y/N: "well we did trap her in a house with the pervert."

Sona: "I see your point. But we mustn't be rude."

Y/N: sigh "your going to be the death of me... I thought it would be your sister but no it's definitely going to be you. Alright let's go."

We walked threw a few cars to reach Rias and her peerage saji decided to tag along because he and issei are friends. Tsubaki came too as she is sona's Queen. The intercom just announced that we where about to arrive at our destination. We then opened the door.

Saji: "yo Hyoudou!"

Issei: "saji, student council prez, VP, and Y/N!"

Rias: "good to see you sona. I'm surprised to be seeing you here Y/N."

Sona: "since you where kind enough to give us a ride on the gremory train I thaught I'd see how you were before we got off."

Y/N: "and I'm here because sona asked me too."

Rias: "were fine if not a bit anchos."

Sona: "perfectly understandable. After all this is no ordinary trip home."

Rias: "Y/N since you are in the underworld would you like to visit the gremory household at some point?"

Y/N: "we shall see Rias. I'm going to be pretty busy."

Sona: "Y/N it's time to go."

Y/N: "right best not keep the magic girl waiting."

Sona then turns towards Rias

Sona: "goodbye and good luck."

Rias: "goodbye. See you again soon."

Time skip

Y/N: "so this is your family home."

Sona: "Y/N there is something that you are going to be needing to know before we enter."

Y/N: "I imagine that there is a lot that I'll be needing to know. So what specifically?"

Sona: "well as you know I made a deal with my parents that I would marry whoever beats me in a game of chess... so my parents will want us sleeping in the same bed."

Y/N: "I figured that much already. But why would that be a issue?"

Sona grew red and looked away.

Sona: "because my sister will be with us again and we both know how she gets."

Y/N: "I see your point."

The door then opened and a butler greeted us inside and led us to our rooms everyone on sona's peerage had separate rooms. We finally got to ours.

Butler: "miss sitri and mr flint hears your room."

He opened the door and sona went red but it was for lots of reasons.

Y/N: "sona?"

Sona was very quiet in her embarrassment.

Y/N: "I know that there was things that I should have prepared for... but this... I don't think I could have prepared for this."

Sona was just standing there blinking

The room was filled with handcuffs and whips and other stuff and magic girl cosplay costumes.

Y/N: "we should probably get out of here before your sister finds out we're here..."

Sarafall: "too late!!"

Sona/Y/N: "ahhhh!!!!!"

Time skip

Y/N: "go to the underworld she said... it'll be fun she said... I have experienced things today that I can never forget."

Sona: "at least you didn't have to ware magic girl cosplay while sarafall spanked you...."

Sarafall: "that was soooo hot." She then leaves the room skipping.

Y/N: "how long are we staying here?"

Sona: "the entire summer."

Y/N: "god help us."

Sona: "ouch!!!" She was holding her head.

Y/N: "sorry."
