Chapter 6

Naruto and Kunou were walking side-by-side on their way to Kuoh Academy, Naruto wasn't too fond about wearing a school uniform. He wasn't one for formal wear. Kunou didn't mind going to school, in fact, she couldn't wait, although Naruto had to admit that she looked absolutely adorable in her uniform.

Kunou's outfit consisted of the normal female Kuou Academy dress attire, a magenta colored skirt, a long sleeve white button-down shirt, a waist tape jacket kilt like thing, and shoulder cape thing I guess you could call it that. Of course, she had to hide her Youkai features, unless the young couple wanted to cause a scene. And as for Naruto, he wore the male version of the Kuou Academy uniform. Basically, he wore a black blazer, white button-up shirt completely open, wearing a blue shirt underneath, black pants, and he wore black shoes. Naruto didn't care what the dress code was, he was not wearing those uncomfortable brown clot-hoppers they called shoes.

"Naru-kun?"

"Yes Kunou-chan?"

"Won't Sona and Rias recognize you?" The young vixen asked while Naruto shook his head. "No, they won't. My identity has been kept secret from the entire underworld only a select few know of my existence. And I know Sera Oba wouldn't break our trust like that, although I'm not too sure about Sirzechs. But I do believe he would keep it a secret, at least I hope he did." Naruto said with a frown.

"Are you sure the seals suppressing our power will keep us hidden from the Devils, Fallen Angels, and Stray Exorcists." The daughter of Yasaka asked slightly nervous while Naruto nodded giving her a reassuring smile. "Of course, these seals were developed by Tsukuyomi-sama himself. Remember it's his seals that keep Kyoto safe from supernatural threats." Naruto said.

"Naru-kun you've met the other members of the Shinto Trinity, haven't you?" Kunou asked while Naruto frowned shaking his head. "I've never personally met Tsukuyomi-sama or Susanoo-sama. I've talked to them through a magic circle phone but never in person." Naruto replied softly.

The young couple came to the gate leading to Kuoh Academy, this place was big, but not as big as the Imperial Palace or some of the mansions in the underworld. But it was still pretty big, and the young couple can clearly sense demonic energy flowing throughout this place. Naruto took Kunou's hand before they made their way through the front courtyard of the Academy. And almost immediately all the students turned their attention to the young couple. On the male students' side, they were all drawn to the beauty of Kunou. While on the female side, they were all drawn to Naruto's handsome figure.

"Holy shit! Do you see the knockers on her." Spoke a perverted young fat male. Which was followed by another male with perverted tendencies? "I wonder if she's' single because she's absolutely gorgeous like a goddess."

"Are you free tonight!"

"Look into her eyes, they're so beautiful."

"Hey hottie, why don't you ditch the dope, and let's have some fun back at my place tonight." That was the most troublesome kid in the entire Academy who howled out to the young vixen. Which didn't settle too well with the son of Tiamat, and now he was debating on whether to kill this kid. Kunou wasn't the only one getting harassed. Naruto had it just as bad.

"Look at him, his eyes, his hair, his body, he's absolutely perfect!" Screeched one of the girls. Another girl with red hair and brown eyes screamed out. "Hey, hottie come back to my place! I got sake and a boatload of porn we can have fun tonight! A lot of fun!" Okay, that last one sends shivers down the Uzumaki turn Dragon's spine and made Kunou want to kill this girl on the spot with her Kitsune-bi.

"I want to be the mother of your child!"

Naruto couldn't believe any of this! He and Kunou were trying to keep a low profile here, but they were getting picked off one by one by all these hormonal teenagers. 'This is absolute bullshit I can't believe this! I'm gonna end up killing every male in this school!' Naruto grumbled and thought. 'I'm scared. The boys back at home in Kyoto were never this aggressive!' Kunou shivered in thought.

Yeah, the young couple made a beeline for the Academy, leaving all the hormonal students behind who were still sending out catcalls and wolf whistles towards them. There first day at Kuoh Academy and they already wanted to go back home to Kyoto.

"Akeno." Rias Gremory, a young beautiful girl with crimson red hair and blue eyes asked while she observed the strange spiky blonde young man and the beautiful blonde girl walking beside him. "Do you know who those two are?"

"That's one of our newer students Uzumaki Naruto-kun?" Akeno answered. "If I'm not mistaken today is his first day at Kuoh Academy? It's almost like he popped into this world." Akeno delicate lips soon formed into a teasing smile. "Why do you ask? Has Buchou become interested in one of Kuoh Academy's newest students~."

Rias completely ignoring Akeno's last comment. "What about that blonde-haired girl walking beside him?"

Akeno then placed her finger on her chin. "She seems to have arrived with Naruto-kun. I believe her name is Kunou-chan no last name. It seems that they may be in a relationship with one another?" Akeno's teasing smile soon returned. "Why you're not jealous are you Buchou~."

Rias' brow began to twitch in annoyance. "No, I'm not jealous Akeno!" Akeno covered her mouth with her hand as she giggled. Rias went back to observing the two blondes. "Naruto and Kunou... Hmm..."

Naruto and Kunou walked down the halls of Kuoh Academy, with one destination in mind to find the Student Council room and get their schedules from Souna Shitori (a.k.a. Sona Sitri younger sister of Serafall Leviathan and the youngest daughter of Lord and Lady Sitri).

Coming to a large set of doors Naruto gently knocked, a few seconds later a feminine voice came from the other side of the door "come in". After hearing the verbal invitation both Kunou and Naruto entered the room. The room was completely empty apart from two young women. The first young woman was a young bespectacled woman with a slim figure, black hair styled in a short bob cut and violet eyes. While the second one was a young bespectacled woman with long straight black hair that extends all the way down to her knees, with split bangs and heterochromic eyes, with a violet left eye and a light brown right eye.

"How may I help you?" Sona asked while she observed Naruto and Kunou with a calculative gaze. Naruto gave the Sitri heiress a warm smile which caused said heiress to blush. "We're here to pick up our schedules. I'm Uzumaki Naruto and this is my girlfriend Kunou." Naruto said in a friendly manner as Kunou bowed her head slightly.

Quickly shaking her head Sona stood from her desk and handed the young couple their new schedules for Kuoh Academy. "Here you go. And please refrain from causing any mischief while you study here." Sona said with a sharp tone.

"You don't have to worry about us we won't cause any trouble for you." Kunou said before waving goodbye. Naruto stayed there for a moment as his eyes narrowed at Sona and her Queen Tsubaki. "You're just as Sera Oba described," Naruto said softly causing Sona's eyes to widen. "Wha… You know my Nee-sama!?" Sona asked/demanded.

Naruto nodded. "Yes, I know her quite well in fact. But I believe a proper introduction is in order. However, I must warn you. You are not to repeat any of this to Rias Gremory…" Naruto said in a harsh tone which caused the two Devils in the room to shiver.

Kunou was gently tapping her foot against the floor wondering what Naruto was doing in the Student Council room. However, she didn't have to wait long as the door opened, as Naruto walked out with a smile on his face. "What took you so long?" Kunou asked her fiancé who shrugged his shoulders.

"Ah, you know just giving a proper introduction." Naruto said in a carefree tone, to which Kunou simply deadpanned at Naruto. Anyone who had known Naruto for longer than a day would know that Naruto never did anything properly. He always had a strange way of doing things and funny enough they always ended up turning out better than the proper way.

Placing her hand against her forehead and sighed. "What am I going to do with you Naru-kun?" Naruto shrugged his shoulders. "I don't know? Love me, feed me, spar with me?" Naruto listed off in a sarcastic manner to which the beautiful vixen slapped him. "Oh, hush you." She playfully scolded him to which he chuckled lightly.

Within the Student Council room, both Sona and Tsubaki both appeared to be much paler. What they just heard from Naruto had scared them, no it downright terrified them. Sitting in her desk Sona had her face buried in her hands as she groaned. "This is bad. This is very bad."

"Sona-sama?"

"What is it Tsubaki?"

"Do you think Uzumaki-san was lying?"

Sona shook her head. "No. His power alone should be enough to verify that he's telling the truth. He's easily on par with an Ultimate-Class Devil. He's not someone you want to make an enemy out of. It's best not to withhold any information from him either." Sona grumbled feeling as if she wanted to cry. 'I hope it was worth it Rias. Because of you "we" could be in a lot of trouble.' Sona thought to herself.

"Should we warn Rias-sama about him?" Tsubaki asked as Sona stared at her Queen as if she was crazy. "I already promised him I wouldn't say anything to her. And I don't know about you, but I currently like my position and I don't want to lose it." Sona retorted.

Tsubaki nodded respecting her king's wishes. Sona stared down at her desk before leaning back in her chair. "To think Beelzebub-sama had a son with Tiamat the strongest of the Godai Ryūō." Sona said as she simply couldn't wrap her mind around it. How could something like this happen and no one in the underworld knew about it? And who was Kunou, yet another mystery that would soon drive her insane?

In the second-year student classroom, we find a very frustrated looking instructor who is trying to regain control of his class. It is complete and utter chaos in his classroom, no one was listening to him, so he commenced Plan B. The instructor reached into his desk, pulling out a blunt object. It had a wooden handle and a long hexagon-shaped cylinder on it. It's a small sledgehammer. What would the instructor need such a dangerous tool for, you ask? Simple. Slamming it on the desk.

There was a loud bang throughout the entire classroom which made all the students jump in fear at their psychotic instructor. Now that the instructor had control over his class again he cleared his throat. "Okay 'students' we have two new students joining us today." The instructor spat out the word student as if it was a curse word. "You two may come in now." The instructor said in a calm and friendly manner, unlike the manner he spoke to his class in.

That was the cue for the young couple to enter the classroom. The door slid open, revealing both Naruto and Kunou in all their glory. The instructor then cleared his throat before speaking in the same kind and gentle manner. "All right you two, please introduce yourselves to the class."

Naruto flashed his usual foxy grin. "Yo! My name is Naruto Uzumaki, let's try to get along with one another." Naruto spoke in a friendly warm tone that made all the females in the room blush and all the males green with envy. Next was both Naruto's best friend and fiancé. "Konnichiwa! My name is Kunou! I hope we'll get along and be friends!"

"Excuse me Uzumaki-kun." Asked the brown-haired girl with large circular glasses. This got the blunette's attention as well got the attention of the adorable but sexy Kunou. "An... Yes, what is it."

"Yes, my name is Kiryuu Aika and I have a question for the two of you. Where did the two of you come from."

Naruto blinked as he stared at Aika as he wasn't expecting such a normal question. "Oh, I and Kunou just moved from Kyoto, and we decided to move here to this lovely little town of Kuoh." Naruto said in a friendly manner. Aika's eyes widened in surprise. "Kyoto!? The two of you moved from Kyoto, why the city so beautiful!? I wish I could live in Kyoto!?"

Naruto sweat dropped at the girl's reaction. "Well I do agree with you Kyoto is a very beautiful city, especially the historical district. Also, we just arrived last night." Kunou answered before Naruto could reply.

"That gaki with the spiky brown hair and brown eyes he's a pervert I can feel it. Just like your perverted Godfather Jiraiya." Kurama snorted in amusement as Naruto couldn't help but mentally nod. 'Yeah he definitely is a pervert alright, I can tell.' Naruto replied as Kunou suppressed a shiver. The young Princess of the Kyoto Youkai was not too fond of perverts.

[Partner the boy with the spiky brown hair and brown eyes, the one glaring at you. He has a Dragon in him however I don't know what dragon is currently sleeping in him.] Ddraig spoke.

{Yes, I feel bad for the poor bastard that's inside him.} Albion said.

'Really now? Do either of you know which dragon is sealed within him?' Naruto asked the two Heavenly Dragons.

[I'm not sure, he's far too weak to tell.] Ddraig said bluntly.

{Plus, the boy has no knowledge of the supernatural world.} Albion stated.

"So, what you're saying is this ero-gaki is nothing more than a big walking target for the Devils and Fallen Angels?" Kurama thought aloud.

This caused Naruto to narrow his eyes he had a feeling that this boy was somehow involved in Rias and Sona purposely ignoring the Fallen Angels in Kuoh Town. But sadly enough neither him nor Kunou could act without blowing their cover. The last thing he wanted was to hear Sirzechs whining and complaining about his precious Rias.

Next came the perverted trio. The only one Naruto and Kunou remembered was Issei; the boy who held a Dragon-based Sacred Gear. As for the other two, neither Naruto nor Kunou couldn't remember their names and they really didn't seem to care all that much about them either. And Naruto swore that he would kill the three of them if they even dare touch Kunou. The rest of the day went like any normal day in school, listening to the instructor yak on and on about stuff the young couple didn't need to know about.

Rias sat there looking at the little white-haired midget known as Koneko. "Are you sure about this Koneko?"

The cute little white-haired girl with her emotionless expression answered. "Hai. Something is blocking their aura I can't tell if their human or not?" Koneko spoke in her monotone voice. Rias frowned at this as she gently tapped her finger against her chin. She then looked to Kiba. "Kiba can you please bring them here after class, I would like to speak to them personally and get to the bottom of why they're here in my territory."

The young blonde boy with a mole under his left eye and steel blue eyes nodded. "Hai, Buchou, it shall be done." With that Kiba and Koneko, both left the room. Rias leaned back in her chair releasing a tired and frustrated sigh. Akeno then decided to speak up at this moment. "Ara ara. It seems that we have a little problem here don't we Rias."

"That we do Akeno that we do."

Naruto stood from his chair the sound of the final bell signified his and Kunou's freedom. Looking towards his fiancée who had a similar bored expression. "So Kunou-chan what did you think of your first day of official school? Because this was the single most boring day of my life, but thankfully we can leave after we finish our mission." Naruto whined.

Kunou rolled her eyes as she playfully slapped Naruto again. Standing up to, Kunou grabbed her bag, as the young couple grabbed each other's hands as they began to make their way out of the classroom only to find an obstacle in their way. That obstacle was none other than the blonde pretty boy named Kiba Yuuto.

"Uzumaki-kun, Kunou-san my Buchou would like to have a few words with you. If you'll please come with me." Spoke the blonde haired pretty boy.

"How about no." Naruto said before pushing Kiba away as if he was nothing more than a ragdoll. This caused an uproar amongst all the girls in the classroom with the exception of a few. Naruto proceeded to ignore them as he made his way out of the classroom with Kunou by his side.

Kiba jumped to his feet. "Wait!" He called out only for Naruto to turn around and glare at him, his once indigo eyes were now blood red with vertical slits. "We're not interested in meeting your "Buchou". Blondie now get lost before you get yourself hurt." Naruto said as he continued on his way, as Kunou stuck her tongue out at Kiba.

Kiba was unable to move the look Naruto gave him was enough to paralyze him in fear. 'What is he!?' The knight of Rias Gremory thought to himself as he couldn't stop shaking. 'I need to let Buchou know about this immediately. Uzumaki-kun could very well become a dangerous threat if not dealt with immediately.' Kiba thought before making his way back to the occult research club.

The young couple finally made it home, no sooner did they open the door that they felt something was off. And something indeed was off? There was another presence in their house, and it was neither human, Dragon, Youkai, or Devil? No, it was a Fallen Angel judging by the signature.

Naruto glanced at his fiancée as she nodded to him, Naruto summoned forth his katana which was forged from the fangs of both Albion and Ddraig. Funny story about this sword the fangs was in Tiamat's possession, and she never knew what to do with them until Naruto decided he wanted to learn how to wield a sword. So, she had the fangs forged into one singular sword, and the Almighty blade was named the Heavenly Claw. While Kunou was preparing a spell and Kitsune-bi to annihilate the intruder.

Upon making their way through the hallways as quietly as possible they could hear the TV playing. Making their way slowly towards the living room and peeking in they noticed the intruder. He was a tall man appearing in his 20s with an average build, black hair, golden bangs, and a black goatee.

The man didn't seem to notice them, either that or he just didn't care. Finally having enough Naruto stepped in aiming his blade at the man. "Who are you! And what are you doing in our house!" Naruto demanded unleashing a large amount of killer intent to which the man lazily glanced at Naruto before waving them off. "Isn't it obvious I'm catching up on my favorite shows. You're free to join me if you want?" The man offered in a carefree tone while Naruto gritted his teeth.

Kunou studied this man closely before her eyes widened, she finally realized to this person was. "Your Azazel the Governor General of the Fallen Angels and Grigori!" This stopped Naruto in his tracks as he stared at the man closely. "Then tell me why are you a faction leader doing in our house right now especially in Shinto territory?" Naruto asked as Azazel glanced towards Naruto.

"Very perceptive of you. I'm glad that you know Japan truly belongs to the Shinto Gods and not the Devils. As to why I am here well a few of my subordinates have disobeyed me and gone rogue. I believe they joined up with Kokabiel, who I had lost contact with several weeks ago, and his trail ends here." Azazel said with a serious expression despite his laid-back tone.

"Kokabiel you have got to be fucking kidding me? How could you lose contact with him? Anyone with more than two brain cells knows he's a warmonger and would do anything in his power to restart the war in between the three biblical factions?" Naruto said. "So, I take it you're the one who sent the Fallen Angels to observe that boy Issei then?" Kunou followed up after Naruto.

Azazel nodded. "Yes, my sources lead me to believe that he has a powerful Sacred Gear possibly a Longinus." Naruto crossed his arms as he frowned at this. "So, I was right he does have a powerful Dragon Sacred Gear. And from what I can gather it's neither Albion or Ddraig and the only other Dragon-based Sacred Gear that I know of contains Vritra." Naruto thought aloud.

Azazel seem to chuckle at this. "You're wrong there are two more Dragon-based Sacred Gear's. Absolute Darkness is a Longinus Candidate Sacred Gear which holds the spirit of the Eclipse Dragon, Apophis. And then there is the other Longinus Candidate Sacred Gear, Diabolism Origin which holds the spirit of the Diabolism Thousand Dragon, Aži Dahāka. They are both Evil Dragons that had reached a level of Heavenly Dragon. Most believe that they were both annihilated, but they were both sealed in Sacred Gears shortly after their demise. The sad part is most people who are chosen to wield their Sacred Gear's end up going insane."

This caused Naruto to frown as he glanced at the leader of the Fallen Angels and could detect no lies coming from him. "So, you believe Issei? Has one of the evil dragons in him?" Kunou said while Naruto was most likely having an internal monologue with Albion and Ddraig or possibly both of them. Azazel nodded as he took a deep breath. "He most likely possesses Apophis sense my apprentice holds Aži Dahāka." Azazel said before standing up from the couch.

"Make sure that if his Sacred Gear activates and he can't control it, you need to dispose of him. Because there can be many casualties?" Azazel said before walking towards the front door. "Wait what about the rogue Fallen Angels?" Naruto said. Azazel didn't stop, nor did he look back. "If they cause any more problems dispose of them any way you like." Azazel said before opening the front door and walking out.

This left the young couple alone before they glanced at one another. "It seems things are going to be a bit more complicated than before," Kunou said before looking at Naruto who pulled out his phone. "I need to get in contact with my Kaa-chan and tell her everything that's been going on. You should do the same with Yasaka Oba." Naruto said not even realizing he called Yasaka by the original nickname he gave her. Kunou nodded as she took out her phone and decided to call her mother in give her an update.

The End
