-3D POV-

As both of them teleported out of the underworld they appeared back in the SC room. There they saw Sona and Tsubaki as well as the girl who tried bumping into him along with a red head.

Y/N: Thank for that Sona. I'll be sure to trow in a few good words about you in the report.

With that Y/N waved his hand and left. While waking to the exit he got a few stares from the students. Probably due to his new familiar still sitting on his head. After he left the school territory he decided to walk around for a while till he walked into a park which was empty.

Y/N: Now that I think about, I didn't ask you your name did I?

Silkworm: Oh right. I kinda forgot about that too. Let me just.

She flew down in front of him and then glowed. When the glowing stopped in her place stood a woman.

Harem: Hell yes.

Meng: Demon king Mi Meng greets Lord Y/N, please call me Xiao Meng.

Y/N: Okay I wasn't expecting that but that's cool.

Meng: *giggle* Expected. Not all familiars have a human form. Although *looks him up and down* why do you have to be so tall?!

She got the point though as she's only tall enough to react to the middle of his chest.

Y/N: Don't know. It's in the family I guess.

Meng: Yeah that could explain it. So what now?

Y/N: Don't know. Look around town and wait for the call from Sona to know where my car is.

Meng: Alright then!

Meng then proceeded to make herself small and invisible to human eye and Y/N put her on his shoulder.

After a while of walking around Y/N got a text from Sona with the address. After arriving at the bus stop and waiting for a bit they entered the bus and sat in a free seat. After one stop a huge man with a stone cold face sat next to them. What was special about the man is that he had a brown bunny on his shoulder. Y/N and the man looked at each other and nodded. After a few stops Y/N arrived at the address and saw his car windows being cleaned by a mechanic. He walked over and the worker noticed him.

Worker: Heya partner. I'm guessing this is yours?

Y/N: Yes. How much for the door?

Worker: None mate. It was enough for me to work on a rare model like this one. Truly a great car.

Y/N: I see, well thank you then.

Worker: No thank you. *tips his hat*

Y/N got into the car and after checking everything he drove off. After a while he arrived at the forest just outside the city and got out of the car. Then a few hours passed of him getting everything out the trunk and setting everything up. Meng helped too. Currently he was meditating not too far from his camp.

Y/N: 'So how do you feel?'

Fauna: 'Very good. Great even. Give or take 5 minutes and I think I'll be able to manifest in the real world in my small form'

Y/N nodded and continued meditating. After 4 minutes a flash of light appeared in front of him and he felt something in his hands. When he opened his eyes and looked down he saw a small girl sitting in his hands.

Fauna: Heya! It worked!

Y/N: Adorable.

Fauna: I know right! Mom always said that I look very adorable like this.

Y/N: Well at least this makes things easier.

Fauna: Yup!

Y/N stood up and headed back to the camp but upon arriving he was met with an interesting surprise.

He was about to speak but ???(Atago) handed him a letter which he opened.

Dear Y/N, we had a little change of plans. A few hours back we got a report that a high class fallen angel is hiding in Kuoh and we think that they have bad intentions. So I'm sending Atago and Takao to help you in case a situation arises. I also took a liberty to get you a job at Kuoh Academy as a PE teacher so you could easier communicate with Sona Sitri.

-Musashi ;)

Y/N: *sigh* *a few quiet swears*

~timeskip brought to you by~

Currently Y/N was walking to the SC wearing a track suit while Atago and Takao wore uniforms that looked a bit different from the usual ones. They also made themselves look a little bit younger.

This got them quite a lot of dirty looks and a guy with glasses tried to say their measurements but failed due to a bullet flying past him, courtesy of Y/N. As they arrived and entered they saw Sona in the room with the red head being there as well.

Y/N: I suppose you already know Sona?

Sona: Yes. I got informed by one of the tengu. And the girls I assume are Atago and Takao?

Atago: Yup!

Takao: Yes.

Sona: Good, then I welcome you to our academy. I will give you your schedules in a minute. Y/N, or should I say Mr.Lioncub, you can get your schedule in the teachers lounge.

Y/N: Understood. And who's your friend here?

Sona: Oh this is Rias Gremory of the Gremory household.

Rias: Nice to meet you. I'm the co-owner of the Kuoh territory. *smiles*

Harem: No.

Y/N: *raises an eyebrow* I don't remember Musashi-sama mentioning you.

Takao: That's because she's not supposed to be here. The permission to temporarily own and stay in this territory were given to the Sitri family and Sitri family alone.

Y/N: Is that so? Well, I think we have some problems Ms.Gremory.

Y/N sent a glare in her direction which made Rias flinch.

~small timeskip brought to you by Koneko eating sweets~

The tension in the room was big. Currently Y/N sat on one of the couches with Atago and Takao standing behind him in their uniforms and katanas ready. On the other couch sat a very nervous Rias and a calm Sona with both peerages behind them who got filled in to what happened when they arrived. A few seconds later not too far from the couches appeared a magic circle and 2 people teleported into the room.

Sirzech: What happend? I came as fast as I could.

Serafall: So-chan what happened?

Harem: Yup.

Sona: *points at Y/N and the girls* We have a little problem.

Sirzech: Hmm? What problem is it exactly?

Y/N: That your sister isn't supposed to be here. Both of you. Sit.

That very second both devil kings sat next to Rias and Sona respectfully while shaking a bit. Mainly because the tone of Y/N's voice reminded them of their mothers when they're angry.

Y/N: Now. When I was coming here to check on thing by Misashi-sama's order I only knew of Sona Sitri and her group residing in this territory. My question is, why is Rias Gremory here?

Sirzech: Well you see- *gets slapped*

Serafall: Shut up! That's my job! Ahem. I will answer the question so the dumbass! Over here won't sugarcoat it so I'll be honest. She acted like a spoiled brat and while I refused to let her go to the territory because of our deal with Musashi-sama, sis-con here gave in immediately and let her into the territory!

Sirzech: That's not-

Takao: That's true. Even when they both were in the meeting with Musashi-sama, Sona acted politely while Rias was a total brat. That was one of the reasons why she wasn't allowed in the territory.

Y/N: I see. Musashi-sama will hear of this predicament. Await for a message and you better hope that she doesn't send me after you.

Sirzech: *serious* Are you threatening us?

Y/N: No. *Fauna appears on his shoulder* Only you.

Sirzech: *terrified* T-thats!

Fauna: Hello Sirzech Lucifer. Still messing with humans I see. I don't like that.

Serafall: *stands up* Please everyone calm down. Let's wait and see what Musashi-sama says about this situation first. I beg you.

Y/N: Hmm. Fine then. For now the Gremory stays. But if Musashi-sama says otherwise.

Serafall: We understand. *bows* Thank you.

Y/N nodded and he and the girls left the room. As soon as the doors closed however they could hear screaming from the inside.

Serafall: *muffled* WHAT THE FUCK WERE YOU THINKING YOU RED HEADED PERIOD TOMATO HEAD OF A FUCKING SIS-CON!! DIDN'T I TELL YOU IT WAS A BAD IDEA!!!!

Sirzech: *muffled* PLEASE DON'T HURT ME!

Serafall: *muffled* *slaps him* SHUT THE FUCK UP AND TAKE IT LIKE A MAN!!

~timeskip brought to you by~

Currently Y/N was sitting in a living room of his new house when a door bell was heard. He stood up and went to the front door and when he opened it he was met with a pleasant surprise.

Y/N: Well well well, if it isn't the little white. Haven't seen you in a long time.

Koneko: Hey. Man I come in?

Harem: Yes.

Y/N: Yes.

He stepped to the side and Koneko entered. They sat in the living room and started to catch up on things.

--------------------------------------------------------------

And that's done. For those who will ask why Koneko looks like that. That's because of Y/N helping them, they didn't get separated and Koneko didn't reject her Nekoshou side so she's an adult now. And a hot one at that. AND she's one year younger than Kuroka so she makes herself look younger so she can attend the academy.
