Looking over his friends one Rikuo Nura smiled at them as they discussed the latest Yokai sightings, they had all matured in the years since Abe no Seimei's defeat the girls had matured and filled out well especially Kana who could easily be most of the guys in the schools wet dream by now with her mid length brunette hair and brown eyes always shining with her youthful innocence never lost, her uniform taught over her new chest she grew into with her skirts a bit short that causes her no end of embarrassment and many boys bloody noses. The rest of his friends had grown up as well, Tori had gained height as well as a few sizes her hair had lengthened a little but she kept her pony tail and with her cat like eyes she has become quiet the beauty with an almost cat like grace. Maki is still just as she was not particularly changing beyond cutting her hair short she's still just as short tempered at times but just as lazy. Kitsyugu definitely hasn't changed much still having his rather crazy hair and his personality and charisma has yet to wane in the least. Shima has kept his punkish spiked hair and kept with soccer beyond that he's stayed very much the same. Then Rikuo himself has changed a fair amount he has become taller and more athletic with sharper eyes and tongue his day self has become much more like his night self-becoming more charismatic, confident, and has taken his mantle of the third heir of the Nura clan seriously though he still attends human school he has become well versed in the ways of the Ayakashi and the clan. As they laughed and chatted about the latest yokai sighted near the school before the door opened with Tsurara the Yuki-onna, having matured physically she is now a true nadeshiko beauty with her long black hair with the blue highlights and while in human form her brown eyes and in yokai her golden eyes gleamed with an almost predatory seduction much like her mother as she has also filled out her figure giving her a perfect hourglass, came through the doors with a smile saying "Rikuo-sama the letters came."

Turning to look at her Rikuo smiled while kana turned to chat with tori but the rest of them turned curious as Tsurara walked up to her young master and handed the letters which he smiled saying "thank you Tsurara."

Blushing lightly, she sat down as he went through them saying "its high school acceptance letters… why is one from Kuoh here?"

Looking at it there was a strange insignia on the top right of the envelope as they all thought about it before torii said "Well didn't it change to a coed high school last semester?"

Shrugging Rikuo said "I guess so otherwise I wouldn't have gotten a letter, anyway where are you all going?"

As he asks that they all have a realization, they are all plan on going to different schools… the Kiyojuji paranormal investigation squad was coming to an end. As that realization hit Kiyotsugu stood up saying "guys lets change this. We need to all stay together, I could never feel right if we were all separated after the years we've spent together."

As each person looked at the other they smiled and nodded saying "Yeah!"

Then Kiyotsugu smiled before saying "So where should we all try to get into… actually I read recently that the area near Kuoh academy had become a hotspot for strange occurrences recently, Nura didn't you say you got a letter from there?"

Looking at it Rikuo nodded before pulling it open and reading it he said "apparently, it's an offer to come and study there. Well if everyone else can get in I'll go along; besides it could be fun."

With his eternal smirk Kiyotsugu stamps his foot on his desk and points out to the distance and says, "Alright then our new objective is to get into Kuoh academy and keep the Paranormal investigation squad together!"

As they cheered Rikuo smiled as school officially let out he went home letting his friends go their separate ways before entering his home as he was tailed by Tsurara, Aotabo, Kurotabo, kapa, Kubinashi, and Kejouro who were his personal guard when out of the main house. Entering the many different yokai that inhabited the old Nura clan house greeted Rikuo happily as he moved through the house greeting some himself before finding his grandfather Nurarihyon out in the garden looking at the cherry blossom tree smoking his pipe. Turning to look at Rikuo he gains his signature smirk saying "aaah how are you my boy?"

Sitting down next to him Rikuo pulls out the letter of his jacket saying, "I'm doing well, however I'm curious do you know this sigil?"

Showing his grandfather, the letter envelope his eyes go wide saying "That's the Gremory family crest. What do the devils want with you Rikuo?"

Raising an eyebrow Rikuo can only say "They are inviting me to study at Kuoh academy. Heh I think I should go, it'll be fun besides all my friends are trying to get accepted there as well."

Nurarihyon only looks at his grandson as if he just grew a second head before laughing saying "Ah Rikuo you are definitely my grandson, just remember who you are and that you have responsibilities here"

To answer Rikuo simply stood up and smirked saying "As if I could ever forget my goal after all I have to become the master of spirits so that yokai and humans can live together in harmony. Now all we have to worry about is what Yasaka will say"

Chuckling Nurarihyon said "Let me handle that old fox."

Raising an eyebrow Rikuo then smiles saying "Excellent, so when it comes around I'll be taking my subordinates with me."

With an eye roll and laugh Nurarihyon simply looks at Rikuo saying "You are so much like your father Rikuo its terrifying what you will accomplish."

Standing up and heading off Rikuo says "Isn't that what Ayakashi are supposed to be grandpa?"

Heading off away from his grandfather Rikuo passed by his retainers who were clearly "not" eavesdropping on his conversation before he simply shook his head saying, "so who wants to help me with this endeavor to Kuoh?"

They all smiled saying "We'll follow you anywhere Rikuo-sama!"

With a smile, he then went on his way to prepare. While elsewhere Nurarihyon went into his private room and began writing a letter to an old acquaintance.

-A week later in the underworld-

Lord Sirzechs Lucifer formerly Gremory sat at his desk reviewing the latest additions, that prick of a fiancé his parents are forcing his cute baby sister with, to the marriage agreement before his wife and queen knocked on his door saying "Sirzechs are you busy?"

Perking up at hearing his wife's voice he calls out "of course not please come in."

Opening the door Grayfia held in her hand a letter with the Nura clan sigil on it and he brightened saying "It seems our friends from Kanto received my invitation."

Raising an eyebrow as she hands Sirzechs the letter which he opens happily as Grayfia says "Kanto? What are you planning Sirzechs?"

With a smirk as he read he said, "Well it seems that our dear rias will have new allies in her corner within the next year however, I do hope they don't cause too much trouble."

Keeping her questioning look she simply shakes her head before saying, "you are always like this you know that?"

Keeping his devilish smirk Sirzechs retorts "Whatever do you mean?"

-In Kanto, mid-summer-

Sitting in the meeting room in his night form, which has matured as well looking much like his grandfather did in his prime, Rikuo looks over all of the subordinate houses as he draws a breath from his pipe before speaking "now I'm sure you're all curious as to why I've called this impromptu meeting. It is to say that for a time I will be leaving the kanto region and going to school elsewhere."

Many of them look at him in surprise others simply stay quiet waiting to learn what their third supreme commander has in store to which he holds his hand out to silence some of the talking before saying "I know how you must feel but do know this, the place I will be studying is not only a place which holds great interest to me, but to the clan. You see I learned before I graduated from middle school there are devils living in Kuoh, and well I think it would be fun to make some friends in low places."

As he finished some keep their incredulous looks as others smile knowing this is how things will always be before one head speaks up saying "and how will we operate here? Who will be in command in your absence?!"

To answer that Nurarihyon simply appears behind Rikuo saying "What you saps forget I'm still kicking so soon?"

Once the original supreme commander showed his presence every yokai there silenced themselves as Rikuo smiled saying "and with that ladies and gentlemen this meeting is adjourned."

And with those final words Rikuo left the chambers and went on a stroll over his area sitting atop the flying snake with Tsurara behind him they looked over Ukiyoe town as he said "You know Tsurara I do love these strolls. It's nice going through the night sky."

With a light blush Tsurara smiles saying, "You do know we'll still be able to do this at Kuoh right?"

Chuckling Rikuo nods saying, "Very true, however we'll have to be much more careful who sees us."

Nodding to each other they continue their night stroll returning to the compound early in the morning ready to face the last days of living in Ukiyoe town for a time. Over the next week school let out for summer vacation and the group all got accepted to the prestigious academy They spent their time packing and with the rest of their parents meeting with Rikuo's mother who would act as their guardian while they would be attending Kuoh. Over the summer the group of friends all made their way to Kuoh, got a place for them all to stay while going to the school. Then the school year arrives and the first year had been a complete and total let down. There was almost nothing supernatural about the first year at Kuoh, the most interesting thing that happened was Rikuo made friends with one Issei Hyoudou and his other two friends, however a "Good" effect was that the yokai kept themselves what seemed to be hidden for now however the counter was they did not meet the devils either. Now with the second year having begun some of the group feel it was a waste of time coming to Kuoh instead of their original choice particularly one irate blonde as she was going off on Kiyotsugu again for dragging her along with his stupid idea "Dammit Kiyotsugu I told you this was a bad idea! We haven't seen a single thing since coming here it's like everything we experienced back home was all a dream!"

They all knew the yokai attacks as well as the Gokaiden house were covered up quickly by the government but none the less they each had scars from that time. The leader of the group sunk further into his chair knowing exactly how she felt but he took a breather saying, "I know how you feel Maki but we are here and well we're still a club and we kept up with the curriculum so we might just have a ride through university."

He smiled at her which diffused her as she huffed saying "alright fine, anyway have any of you seen Nura? He has been gone for a bit."

Looking around the room both Rikuo and Tsurara were indeed gone despite it being midday tori and Shima both shrug not knowing.

-elsewhere in Kuoh-

Rikuo and his group were moving through the streets before he notices Issei waiting by a bus stop he lets his guards explore before he approaches saying "Hey Issei."

Hearing his name the high school pervert smiles turning saying "Rikuo. How are you? What are you doing here?"

Keeping his smile, he says "Just out exploring a bit more since last year I was busy or I kept to my apartment and school so I found some time and well here I am. What are you doing out here?"

With a smirk and a sudden spark Issei looks at his friend saying, "I got a date with a real hottie"

Raising an eyebrow Rikuo bursts out laughing which causes Issei to make a feigned hurt before he simply smiles saying "Ill prove it to you stick around she should be here any moment now."

Smiling he nods saying "Alright Issei let's see what kind of girl you snagged."

Waiting with him for a bit a rather lovely girl in a bat cosplay comes up to the two friends handing out flyers handing one to each of them with a smile to Issei but a slight pause with Rikuo as she then leaves quickly as they both shrug and pocket the flyer as Rikuo senses the magic coming from the symbol on it and will investigate later. After another little bit of waiting a beautiful girl with raven black hair and violet eyes approaches and says "hi Issei… who's this?"

Gaining a sharp glare in her eyes Rikuo simply keeps a kind smile as he adjusts his glasses saying "Nura Rikuo a good friend of Issei here, so is this your girl?"

With a bright smile Issei wraps an arm around the "innocent looking" girl saying "Yup, this is Yuuma Amano, and get this she asked me out!"

He gives her a quick but sharp spike in fear having let his night blood gently mix with his day blood saying "Isn't that nice. I do hope you two have a nice date. Later Issei."

Waving to his friend and watching him leave Rikuo moves into a side alley and sees Kuroumaru waiting as he simply says, "follow them do not interact with them simply observe and report back, understood"

Nodding the crow tengu launched up into the sky and began following the two people silently keeping vigil. Returning to his day Rikuo knew that Issei will be alright with Kuroumaru watching them. Heading back to their apartment Rikuo is greeted by his friends in the middle of another argument which he becomes the mediator as usual.

-at a certain fountain park at dusk-

Kuroumaru had been tailing the two children for several hours and could not understand why his commander would give him such a simple task. So, he continued to watch and saw the girl change into a form like his own and his siblings but the energy she gave off was definitely of the fallen angels. Gripping his staff, he prepares to attack but remembers what Rikuo said 'observe and do not interact' so he steals himself as he must watch as his master's friend is speared with light. Gritting his teeth, he knows how Rikuo will react to learning of his friend's death but he could not stop it as he followed orders to the letter, however after the fallen disappeared he noticed a red-light glow from his pocket as a spell seal appeared nearby and out of it a buxom red haired devil appeared and he watched as she resurrected Issei and vanish through the same seal.

Having finished his task and believing he remained unseen Kuroumaru took off himself and returned to the apartment that his master and his friends from kanto were staying. After reporting what he observed he watched Rikuo grit his teeth and his night form take over from the anger that radiated off him from learning what the fallen had planned in the first place but relax slightly as he knew the devil resurrected him and now with the description he knew who the local devils were, Rias Gremory and her club had to be the ones. After dismissing Kuroumaru Rikuo goes to his room to rest his body so his day self won't pass out in the middle of class thinking 'what a pain, but this should become quite interesting'

With that last thought he fell asleep ready for the next day and to see what will happen next.
