Chapter 1: Awakening of Power.

Sakakino City is a peaceful city located in Japan's Tokyo Metro Area as it home to the famous Sakakino Academy which is the only school that deals with the Mythology of Japan and the World. It's also home to the Spiral Sun Corporation which is owned by the Hyuga Family. Also this city is home to a branch of a Mafia family known as the Vongola Family and the city is also home to the true heir of the Vongola Family.

Walking toward Sakakino Academy are two teenage boy that appear to be sixteen year old of age as one of them has sun kissed blonde hair and sky blue eyes and was wearing a custom version of the Sakakino Academy male school uniform as it was orange and black in color. He was also wearing a odd belt buckle around his waist. This is Uzumaki Naruto the Boss of the Vongola Decimos. Walking next to him is a very pale boy with black hair and black eyes as he was wearing a standard black Sakakino Academy male school uniform. This is Sai the Storm Guardian of the Vongola Decimos.

"Kami why do I got to go to school still when I'm the Boss of the Vongola?" Naruto asked out load to himself.

"Because Naruto-sama it is not right for you to just skip out on your education and also you have to find a wife as well. And a school seems like a most likely place to find yourself a wife." Sai replied as he was reading out of a book on relationships.

"Sai you really got to stop reading out of those books man. I mean you got Ino pregnant because of those books." Naruto commented as Sai looked at him.

"But Naruto-sama the book said I'm suppose to show everyone that she is mine." Sai replied as they kept on walking.

"And you believe getting her pregnant was the answer?" Naruto asked as he was really confuse on his friend's reasoning.

"No that was actually Ino's suggestion." Sai simply replied as Naruto just plain looked at him like he was crazy.

"Okay then let's drop that subject and let's get to Vongola related business then." Naruto said as Sai nodded his head.

"Okay then from what I remembered from reading several of the report these past few weeks a number of our guys are getting rubbed out." Naruto said as he was getting angry that someone would kill his people.

"Yes Naruto-sama and there are also reports of some of our men disappearing without a trace as well." Sai said as Naruto grind his teeth in anger.

"Okay then tonight I will search for the one responsible for these crimes and deal with them myself."

"But Naruto-sama!" Sai said in shock at what his boss is saying.

"No buts Sai and also I order you to spend more time with Ino instead of constantly being my bodyguard." Naruto ordered as they finally arrived at the school now as Naruto then sees a beautiful teenage girl of sixteen as she was wearing a purple version of the Sakakino Academy female school uniform as she has long indigo hair and pale lavender color eyes and a very impressive bust as well. She was walking toward them.

"Oh hello Hinata-san how are you doing today." Naruto said hello to his best friend Hyuga Hinata who is also the Heiress of the Spiral Sun Corporation.

"Oh hello Naruto-kun and Sai-san." Hinata shyly said as she started walking with the two boys.

"So Hinata-san how is your company doing anyway since I heard you now leading the Spiral Sun Corporation since your father died?" Naruto asked his best friend who just blushed.

"Eh it's doing alright so far. My company has been making a good profit so far." Hinata responded as the group headed for there homeroom class. All three of them wander around the Academy Hallway as they soon stopped in front of a classroom door as they soon enter it.

"Oh hello Uzumaki-san, Hyuga-san and Sai-san. Please pick a seat and wait for the class to start. But Sai you do have to sit by Ino since you did kind of got her pregnant." the teacher said as he pointed at a platinum blond teenage girl who appeared to be six month pregnant.

"Sai I'm still kind of disappointed in you for getting my niece pregnant." the teacher said as he was kind of disappointed with both Sai and Ino in having a child so early in there life. The Teacher's name is Mark Frey as he came from United States of America to teach Mythology in Japan.

Everybody was already seated as Naruto was sitting next to a teenage boy with black hair and blue eyes. The boy was wearing a black bomber jacket with fur around the collar and bottom hem and also some around the wrists on his sleeves. He also wearing black pants as well. The boy was also emitting aura of a delinquent. This is Ryuji Sonozaki and Naruto still remembered how Ryuji punch Makoto Ito for cheating on his best friend Kotonoha Katsura for a girl named Sekai Saionji. Hinata was seated next to a girl with long black hair and black eye as well. She had a generous bust size as she was wearing a black female school uniform. This is Kotonoha Katsura and she was still a bit depress that her boyfriend Makoto cheated on her with her best friend Sekai. But she was slowly getting through it with the help of her childhood friend Ryuji.

"Okay class everyone quiet down so we can start today's lesson." Mark shouted to be heard as everyone quieted down.

"Okay then today's lesson will be about the Ancient Ones. But first can anyone tell me about what they have heard about the Ancient Ones" Mark asked as Hinata raised her hand in the air.

"Ah Hyuga-san so what have you heard about the Ancient Ones?" Mark asked Hinata.

"I heard that each of the Ancient Ones were demons that were so powerful they were treated like gods." Hinata replied.

"That is correct Hyuga-san. But there's actually more to the whole story of the Ancient Ones. For example each of the Ancient Ones represented one of the Seven Deadly Sins. Which we are all going to be researching for today so take out your mythology textbooks start pairing off into groups and begin looking up the Seven Deadly Sins on page 110 and also write down several notes on the sins as well." Mark said as everyone started pairing off into different groups as they working on there assignment.

Six hours later as Hinata was walking toward her company building as school finished. She decided to take on walking down on a street lane that she never been to before as she took notice there was barely anyone around. Soon a fog bank started rolling in as Hinata try to see through the sudden fog cover. Soon she started hearing heavy footstep in the fog right now.

"Is someone there!" Hinata called out as the footstep stop for minute before resuming. She started to panic as she started running with the footstep running after her as well. Hinata then spotted a opened store as she quickly rushed in as she close the door behind her. She then looked though the store window as passing by the window was figure in gold armor as it kept walking by.

"Hello there ma'am did you came into my store for a reason?" A voice spoke up from behind Hinata which quickly startled her.

"AAAHHHH!" Hinata screamed as she quickly turn around as right behind her is a man dress in a white business suit and wearing a white fedora.

"I am very sorry for scaring you Hinata Hyuga." the men said with a smile that will make even angel and demon unnerved.

"How did you know my name?" Hinata asked in shock as the man before her presented her with a odd gem.

"Don't worry Hinata-san. My name is Ankiseth and I'm just a simple magic shop owner. But you can have this before you go as a thank you for visiting my store." Ankiseth said as Hinata slowly took the fire-red heart shape gem from his hand as she looked at it.

"Just to let you know it is called Burning Heart and I believe you'll find it is very useful to you in the near future." Ankiseth said as he started walking away from her.

"Thank you Ankiseth-san for this gem." Hinata said as she exit out the store as Ankiseth looked at her departing form.

"No Hinata Hyuga thank you as your story is just beginning right now." Ankiseth said as he started laughing.

Meanwhile Hinata was walking through the fog again as she looked at the heart shape gem in her hand. She was wondering on why that store owner gave her the gem. She was so into looking at the gem that she didn't take notice of someone standing in her path as the fog was clearing up. She then bumped into the person that was standing before her.

"Oh I'm sorry..."Hinata stopped what she was saying as standing before her was a giant of a man as he was standing over 3 meters tall. He was wearing full suit of gold armor as he was looking down at Hinata.

"Ah there is the girl I was tracking down. I thought you had gotten away from me." the tall armored man said as Hinata started backing away from him.

"Who are you and what do you want from me!" Hinata shouted at the man before her as he start approaching her.

"Well little miss my name is Pimp King and I'm here to make you one of my hoes like all the other girls I have kidnapped." Pimp King said as he started advancing on Hinata.

"You stay back!" Hinata shouted at the man who just backhanded her sending her flying and hitting the pavement hard.

"Now I not going to let any women talk to me like that except for my wife." Pimp King said as he slowly started advancing on Hinata as she was weakly trying to get up.

"I'm not going to be made into some kind whore for some pimp." Hinata muttered to herself as Pimp King then kicked her sending her flying.

"AAAAHHHH!" Hinata scream in pure pain as she hit the pavement hard.

"What am I supposed to do?" Hinata asked to herself out loud.

"What about you activating me?" a mysterious voice asked her as Hinata eye widen in shock as she looked at the Burning Heart gem that she was still clutching in her hand.

"Did you just talk to me?" Hinata asked the gem.

"Yes I did talk to you and I say you should activate me if you do not what to become this man hoe to increase his profits." the gem said as Hinata got up from the pavement.

"What do I say then to activate you?" Hinata asked the gem as she quickly dodged out of the way of a heavy punch that shatter the pavement and street on impact.

"Just hold your hand out with me still in your grasp and call out Burning Heart Activate and I do the rest." Burning Heart said as Hinata holding Burning Heart out in front of her as she took a deep breath.

"Burning Heart Activate!" Hinata shouted out loud as the Burning Heart gem started glowing bright and blinded Pimp King.

"Someone turn off the light show!" Pimp King shouted as the Burning Heart Gem started floating in front of Hinata.

"Mahou Shoujo Mode Activated!" the gem shouted as Hinata clothes suddenly exploded as she start floating in the air and curled into a ball. Soon ribbons of white, blue, lavender and sliver started appearing around her as they started forming around her as a ray of light shine on a flower as it suddenly started to grow huge and bloom showing Hinata in the middle of it as she was wearing a new outfit. She was wearing white long boots, a blue short skirt, lavender tight shirt and detached sleeves and a sliver tiara with a sapphire on it. The heart gem also took on the form of a knuckle like weapon as it gem was shinning brightly. Hinata then looked at herself after the transformation as suddenly a name popped into her head.

"I am Magical Lavender!" Hinata shouted out as Pimp King regained his eye sight.

"So you are a Magical Girl huh? Well that just makes you even more desirable!" Pimp King shouted as he charged at Hinata.

Pimp King threw a right cross at Hinata who duck under the blow as she then punch Pimp King in the chest. The force of her blow push Pimp King back a little. She then drew her arm back as the gem start to glow.

"Gentle Impact." Burning Heart said as Hinata hand was glowing in gentle blue color as she did what appear to be a very weak punch to his chest.

"That is a very weak punch little girl." Pimp King said as he was about to counterattack when he suddenly stopped as he clutch his chest in pure pain as it almost like his heart is about to explode any second.

"What did you do to me Magical Lavender?" Pimp King asked Hinata in terror as he feel his heart suddenly expanding as when Hinata struck at Pimp King she sent a burst of mana directly into Pimp King heart which started expanding it.

"You know little girl I'm just going to come back and get you. You can't get rid of me that easily." Pimp King cryptically said as his he got up as he was about to punch Hinata's head off when suddenly Pimp King freeze up as he then imploded.

"It's a good thing I came in the nick of time." A woman's voice shouted as Hinata quickly straightened up in shock as she quickly looked behind herself as running directly toward her was a woman who appeared to be twenty-five years of age as she appeared to being of both Asian and Caucasian descent. The woman had blue eyes and platinum blond hair. She was also wearing a outfit that consists of a sleeveless black leather top that is tied around the front. She also wears torn blue jeans along with buckled black boots that come just under her knees. The outfit also had a black belt, a bracelet and a silver name tag necklace with the name Aya Brea on it. The women was also carry a handgun with her.

"Who are you?" Hinata asked as the woman approached her.

"My name is Aya Brea and it's a good thing I stopped you from experiencing your first kill." Aya said as she got close to Hinata.

Meanwhile within an alleyway, a person was laying on the ground as he was wearing black boots, black pants, crimson long sleeve shirt with loose sleeves, a silver necklace with the kanji for despair, black gloves and carries two handguns and an assault rifle on his back. The person's eyes suddenly opened up as he got up from the ground and he then took notice in the next alleyway there are four dead bodies of Vongola members.

"What the hell happen here?" the man said as he then saw a stumbling black armored humanoid with a long bladed arm, small moth like limbs on its hips and there 'helmet' similar to that of a Komodo dragon slowly approaching him. The man quickly responded as he shot the thing several times with his handgun as it fell to the ground and it dissolved into thin air.

"Twisted." the man simply said as coming into the alleyway was Naruto who kept his promise on trying to find out who was killing off his people as he heard several gunshots coming from the alley. Naruto stopped in shock at the men before him.

"Frey-sensei? You're the one that has been killing my men?" Naruto said in shock and anger at the person before him and the men was actually Mark Frey.

"Henshin!" the odd belt buckle said as Naruto pressed a small yellow button on the belt.

"Henshin!" Naruto shouted as his odd belt buckle released an orange and yellow light that enveloped him as soon Naruto was soon covered in a black body suit as he had yellow armor on his torso and shoulder. Orange armor on his forearms, knees and shins. His helmet which covered his entire head was yellow with orange highlight as it seems to be based off a chimera as two horns were on top of the helmet and giant blue lenses that served as eyes.

"Kamen Rider Kirin!" Kirin said as Mark Frey looked at him oddly. Kamen Rider Kirin formed a pair of Pata weapons known as the Kirin Pata over both of his hands.

"No I haven't. And that is an odd ability. I guess we will be unable to reconcile this with words." Mark said as Kirin went to attack him as Mark suddenly jumped and use Kirin's head as a stepping stone to dodge Kirin's attack.

"I guess not." Mark said as he pointed his handguns at Kamen Rider Kirin. When suddenly the two of them were surrounded by a huge group of the black armored humanoids.

"What the hell are these thing?" Kirin shouted as he looked around.

"They're called Slackers. They are a type of being known as a Twisted which are creatures that used to be human before they were transformed by Kurayami Kaien, the Ancient of Sloth. They have been killing your men or maybe some are your men and there is no way to change them back." Mark said as he pointed his handguns at the surrounding Slackers.

"So you know about these thing how?" Kirin asked as one of the Slacker swung its long arm at him which he used his Kirin Pata to block it.

"My girlfriend." Mark simply said as he shot a Slacker in the head as it dissolved away.

"Most of the girls in class won't be happy about that." Kirin simply said as he quickly sliced a Slacker in half.

"Why's that...actually save it for after we destroy the Slackers." Mark said as he took his assault rifle off his back and start unloading into the Slacker horde killing the Twisted creatures en mass. Naruto was slashing at several of the Twisted as they kept on coming out of the wood works. Naruto then touch a button on his belt.

"Element Charge." the Constellation Belt said as wind started forming around Naruto as Mark quickly got on the ground.

"Kirin Blade Twister!" Naruto shouted as he spread his arm out as he started spinning in place as he then start launching blade made of pure winds at the Slackers cutting them down in the process. Soon he stopped rotated as all the Twisted start fading away.

"Can't believe I have to put my own men down." Kirin said as Mark got up from the ground.

In a weird dimension standing around a huge table were six people and one person was sleeping on a couch. One of them was a man of unknown age as he was wearing a black cloak and with an armored suit underneath it as he was also wearing a odd helmet that almost resembled a spiral eye design as some spiky black hair was sticking out of the helmet. This is Uchiha Madara the Ancient One of Pride. Next to him sitting on a throne made of gold was a tall, dark skinned, muscular man. He was wearing a black outfit that cover most of his body as he was wearing a white hood and a black mask on his face with his eyes being the only visible part. His eyes were a green irises, no pupils and red sclera. This is Kakuzu the Ancient One of Greed.

Next to Kakuzu is a man that is sitting on a throne made of sliver and he appeared to be twenty-two years of age and has a lot of black scruff on his chin which matched his long black hair in a ponytail. He wore a fancy Victorian suit and had white gloves. This is Yuhi Ryumen the Ancient One of Envy. Next to him sitting on throne made of pure flames is a teenage boy with spiky black hair that had a blue tint to it. He had cold onyx colored eyes as he was wearing a similar outfit to Madara except without the mask which showed a handsome face and his outfit color was blood red and black. This is Uchiha Sasuke the Ancient One of Wrath/Rage.

Sitting on a velvet chair was a teenage girl of seventeen with a very curvacious figure as she was wearing a light blue silk kimono and she has E-cup size breast. She also has short red hair and has a couple of freckles on her face that made her look cuter as she seems to be snacking on some cupcakes. This is Nysos the Ancient One of Gluttony. Sitting next to her on a similar chair was a similar age girl as she has black hair in two pony tails and golden eyes and she wears a red cloak with a hood, short black frilled dress that is low cut to show off her F-cups and crimson high heels. This is Talim Lakeforest the Ancient One of Lust.

Sleeping on a couch nearby was a teenager boy of nineteen wearing black boots, black military pants, twin black belts that crisscross holding two retractable shuriken, loose black shirt, and a black long coat. He also has white hair almost like someone scared the living daylights out of him. On his face was a playboy magazine. This is Kurayami Kaien the Ancient One of Sloth.

"It has been a while my allies." Madara said as Kaien was still snoring and very loudly as well.

"Will some one wake him up? And get that filth out of here?" Madara said as he was annoyed with Kaien and the smut. Kaien woke up but the playboy was still on his head.

"You heard him Kakuzu. Out!" Kaien said as Kakuzu looked at him annoyed.

"He was referring to your smut!" Kakuzu snapped at him.

"That's mine thank you very much." Talim said as Madara just looked at her.

"Never mind then." Madara said as Nysos kept on eating some cupcakes.

"Kaien does realize he can just ask you to get naked right?" Nysos asked Talim.

"Yeah I do but Talim likes to have me look at these...hey this one looks like you Ny. Mind if I do a comparison?" Kaien said as he saw one of the naked women in the playboy must have looked like his friend.

"Did you just ask your best friend to get naked for you?" Nysos asked Kaien in shock.

"Yes I did." Kaien said like he was talking about the weather.

"After the meeting. After all you know how much I like to watch you and Talim." Nysos said as Sasuke just looked at her angrily.

"Why don't you just join them you stupid bitch!" Sasuke shouted at the Ancient One of Gluttony.

"Because what if I'm bad and lose my friendship with Kaien." Nysos said as Sasuke just looked at her more angry now as he was slowly losing his temper.

"ENOUGH! We have a meeting to take care of!" Madara shouted as he wanted to get this meeting going.

"Kaien I hear you have been sending your Twisted to attack the humans." Madara said as he can tell Kaien is looking at him though the smut.

"Only mafia guys cause Tally asked me to." Kaien replied.

"That is true. I was bored." Talim said as she was truly bored and she wanted to see some killing.

"That is quite all right. The humans have forgotten about us and need to remember who we are." Madara said

"What ever." Nysos said as she started eating a banana.

"Bet you wish that was Kaien huh." Talim teasingly said.

"He's only my friend!" Nysos said.

"Which is why you have sex shrine to me in your closet." Kaien said as Nysos looks horrified that he found out about her secret shrine. While everyone else, except for Talim who was giggling like a maniac, was looking at Nysos then at Kaien.

"I learn a lot when I sleep." Kaien simply said.

"We are off point again. Any plans Madara? Sasuke asked the Ancient One of Pride.

"For now Kaien I want your Twisted to continue to reek havoc. Also Nysos send in your zombies every once and a while as well until further notice." Madara order the two as the meeting came to a end.

"Okay then! Nysos it's time for you to sleep with Kai-kun!" Talim said as Nysos started to blush very red as Kaien finally lifted the playboy off his face.

"You don't have to Ny but you do have to get naked." Kaien said as Nysos still was blushing.

"That I can live with." Nysos replied still blushing as both her, Talim and Kaien went to Talim chambers.
