A Few Weeks After Y/N's Birthday

Y/N was currently walking through the shopping town with Irina. The reasoning was because Halloween was the day.

Sure Y/N was happy, but he was quite worried for Irina. She had an amazing body and she might pick a costume that was revealing, allowing the various boys to ogle at her body. 

Irina: Boo?

Y/N: Huh? Sorry what was happening?

Irina: I was asking what you wanted to do after buying a costume? We still have time before the party that Rias is holding at the old school house.

Y/N: Want to just walk around?

Irina: Anything to be with you!~

She pecked his lips, which caused the black haired boy to smile in response. Afterwards, he pulls her in for a deep kiss. He deepens it even more by pushing his tongue in, which Irina accepts as the two explore their territories.

Separating from the kiss, the two walk down the shopping town, enjoying the company the two shared.

Timeskip-Night, Old School House

Y/N was walking with Irina to the Old School House. He was dressed up as a Devil, but the ones depicted in kids cartoons. He even bought red contact lenses to complete the aesthetic.

(A/N): Picture on top.

Although, it was Irina he was worried about. Irina had dressed up as a female kunoichi. When she bought it and showed it to Y/N, he had a nosebleed. He was fine with it, but the only problem was it was revealing.

Irina: (shivers) I-It's a b-bit cold h-here.

Y/N: (sigh) I told you to wear a jacket, but no. You told me you would be fine.

Irina: But it said that it wouldn't be that cold tonight!

Pouting, Irina looks away, crossing her arms at the same time.

Y/N smiles and rolls his eyes, taking off his jacket and putting it on her. He then wraps his arm around her shoulder and kisses the top of her head.

She smiles as she leans into him more. She loved him so much.

Arriving at the Old School House, the doors opened and they were welcomed by Rias, who was wearing the same revealing outfit she wore to Issei one night.

Rias: Glad you could make you two. Nice costume, Y/N.

Y/N: Eh, it's nothing special.

Rias: Well, come on in. Everyone is waiting inside.

Walking in, they spot everyone all around. Kiba was over talking with Tsubaki, as the two have been getting more intimate lately.

Sona was watching Saji, making sure he wasn't doing anything stupid or perverted. Issei was being watched as well, by Koneko and other members of the Student Council. Akeno had went to the party in her Shrine Maiden outfit, serving tea at the same time.

Kiba was wearing one of Y/N's old cloaks from his early mercenary days. It was cleaned up a bit and it wasn't made suspicious as there were humans there. Rias had made the party open to the whole school and quite a lot of guests had come. Azazel was still wearing his suit, hanging by the bar that Agil had set up in the corner. Agil was wearing his mercenary armor too, posing as a "noble warrior."

Klein was wearing his samurai gear, but the normal people there thought nothing of it as they believed it to be a dedicated costume. Sinon had shown up, wearing fake cat ears and a tail, posing as a Cat Saith from Yggdrasil. Asuna had the same idea as Y/N, dressing up as a Devil that looked like something out of a cartoon. Serafall and Sirzechs were in the back, chatting. Serafall was wearing the pirate costume that Y/N had bought for her when they went shopping on his birthday. Sirzechs somehow managed to escape his wife to attend the party, completely neglecting to do the various paperwork that he had left in his office.

Asia had wore her old nun clothes and Xenovia had dressed up as a samurai as well, standing off to the side. Gasper's room was locked and the same vampire boy was in there, having the time of his life as he sat in the dark while playing the game system Issei had bought for him.

There were a few games here and there. Some of them really just stood around and talk, which Y/N was talking to Kiba most of the time as Irina had walked off to join the other former church members.

Soon enough, the adults had gone elsewhere, in Rias's office to drink, while the girls of the bunch had pushed the boys out of the room, putting them in another room of the house that was currently unused.

Y/N: So...now what?

Kiba: I don't know. What do you think the girls are planning?

Saji: Who knows? Sona-kaichou can be really scary. Who knows what she's got planned.

While the three boys were talking, off to the side were the perverted trio, talking about certain plans.

Issei: (whisper) So, what's the plan? How are we going to peep without getting caught? Especially by those three.

Motohama: (whisper) Don't worry. Matsuda, you got the rope, right?

Matsuda: (whisper) Yep!

Y/N: What the hell are you three talking about?

Looking over, the perverted trio had gotten devious smirks, making the other three nervous.

Y/N: Guys? What are you doing?

Saji: H-Hyoudou? W-What are you guys planning...?

Kiba: Issei-kun?

From behind the doors, the girls had planted their ears up against the door. Shuffling and the sounds of a scuffle could be heard behind the doors.

Grunts and yells were heard as crashing noises were made relevant as well.

Irina: What's going on in there?

Kiryuu: Oh? Do you think the boys are doing something juicy?~

Akeno: (thoughts) Whatever it is...it must be hot.

Akeno licks her fingers as Rias and the other girls had looks of confusion and curiosity on their faces.

Finally, they decided to open the door and looked inside. Inside, Y/N, Kiba, and Saji were tied up together, tape on their mouths as their pleas were muffled.

They looked at the tied up boys eyes, which were gesturing them to look in the nearby closet. Opening the door to the closet, Issei and the perverted trio had a monitor set up with the screens showing where the girls were last were, in the living room area. Now realizing that the girls were behind them, the three boys looked behind them, only to be met with angry looks. The most visible were the ones that were on the kendo team.

Long story short, the three perverted boys were being chased by angry girls holding kendo swords. Outside the ORC building were the girls of the ORC, watching Issei and his perverted friends get chased around.

Koneko was the only one who had a look of amusement as the other girls were worried, especially Rias.

With Y/N, Kiba, and Saji

Saji: (muffled) Do you think someone is going to help us?

Kiba: (muffled) What?

Saji: (muffled) Do you think someone will help us?

Kiba: (muffled) What?

Y/N: (muffled) I don't think we can here you through this tape.

Saji: (muffled) What?

Kiba: ...

Y/N: ...

Saji: ...

Y.N: (thoughts) This is going to be a long night...
