Hello and welcome to a new fanfic. Here it is, the moment you've been waiting for! Sorry, couldn't resist. Anway, I finally got around to starting my Kuroinu x Naruto fic. Now then, let's get to it.

As usual, I own nothing.

AN: Co-Authored by Zero Arashi Uchiha.

The planet Earth. So big. So full of mystery. Of the many continents that make up this world, two are the most important.

The Elemental Nations. A continent made of several others. Here, Shinobi, or ninja, are the main superpower. These ninja serve and protect their villages and at often times, eliminate threats. Using the power known as chakra, the ninjas are able to perform superhuman feats.

Then there's the other continent. Eostia. A land of magic and fantasy. Much like the Elemental Nations, Eostia is part of a much bigger land. Here, there are other races alongside mankind. Elves, demons, ogres and much more. Unlike shinobi, those who live in Eostia depend on magic.

These two worlds, while co-existing, are normally separate. And it is a child born of both worlds that will tear down this wall.

Naruko Namikaze Uzumaki. A child born of the union of Konoha's Fourth Hokage, Minato Namikaze and the Princess of Uzushio, Kushina Uzumaki.

On October 10th, Naruko was born alongside her twin sister, Mito. During that time, a madman unleashed a monster upon the village known as the Kyūbi no Yōko, the Nine Tailed Fox. Minato fought hard to defend his village and his family. At the cost of his own life, the Fourth Hokage sacrificed himself to split the Bijuu in half and seal the individual pieces into his newborn daughters. The Hokage's wish was for his children to be seen as heroes for containing the Nine Tails. That wish was granted. Partially.

While Mito Uzumaki was hailed as a hero, Naruko was treated like the plague. More times than she could count, Naruko was beaten, scorned and isolated in her own village. To make matters worse, her own mother, Kushina, neglected her in favor of her twin. It wasn't until the girl was eight years old that she realized her home wasn't safe for her. Sadly, the villagers wouldn't let their favorite pariah go. Naruko was cornered and beaten to near death. Just when it looked like she would die, an unlikely savior appeared. Her name was Olga Discordia, the dark elf queen of Eostia.

Olga had detected the Kyūbi no Yōko when it was released during the night of Naruko's birth. She had heard tales of the nine Bijuu and thought the fox would make a wonderful addition to her empire. But once the Bijuu was sealed, the trail went cold. Olga could only feel small traces of the fox's power here and there for the last eight years. Until she found Naruko. Disposing the human trash was easy for the dark elf queen. Afterwards, Olga questioned Naruko about her situation. When the dark elf queen learned of Naruko's life, she was once again reminded of her dislike of humans. Olga could see something in the young girl. Potential to be something greater. It was then she made her decision. To raise Naruko as her own while also gaining the power of the Nine Tails for her empire.

It was October 10th, eight years after the Nine Tails attack, that Naruko Namikaze Uzumaki disappeared from the Elemental Nations. It would be another eight years when the girl who was hated and ignored, would return.

The Dark Castle. It stands as a reminder of the power of Olga Discordia and her empire. It is here where the dark elf queen sits upon her throne while another kneels before her. The person in question is known as Zafrina Discordia, formerly Naruko Namikaze Uzumaki.

When Olga brought Naruko to Eostia, she was immediately blood adopted by the dark elf queen. The former human was renamed and had severed her ties to her old life.

Zafrina has grown over the years. She has become a beautiful, well-endowed young woman with caramel colored skin and pointed ears, a signature trait for dark elves. She has violet eyes and long black hair tied up into twin tails with two black ribbons. On top of her head is a black and gold tiara. She also has a rose colored tattoo in the middle of her chest, right above her breasts. *.Hack G.U Haseo's Third Form Tattoo* Zafrina wears a black hooded mantle with a ribbon lace over a purple & white sleeveless, strapped crop top that shows her cleavage and midriff, purple dangerously short shorts with a brown belt around her waist, purple arm sleeves wrapped in bandages, purple thigh-high stripes strapped boots wrapped in bandages.

No longer was Zafrina the weak human she once was. Now you may wonder: "Weak?" That is because Olga's blood adoption revealed a few things. Such as the seals that kept Zafrina weak, a loyalty seal and even a slave seal. It was obvious that the seals were designed to make Zafrina weak and submissive. Thanks to Olga, Zafrina was free to live up to her full potential. Along with her training as a Kunoichi, the new Dark Elf Princess is now an expert magic caster and swordswomen.

"Zafrina." Olga says.

"Yes?" Zafrina asks.

"Our spies have made some progress." Olga says. "We now have a lead on Volt."

Hearing the name causes Zafrina to snarl before quickly regaining her composure.

Volt. The leader of Kuroinu, the Black Dogs. A mercenary group that was originally hired by the Princess Knights to help them defeat Olga and her monster forces. However, they had their own agenda. Volt was able to obtain Olga's resources and convinced her monsters to join their side. Their goal was to create an empire where the woman are forced to appease the sexual desires for the men of the country. Volt would've succeeded if not for one thing. Zafrina.

The Dark Elf Princess was out at the time of the attack on the castle. On her way back, Zafrina was met with a loyal servant of Olga. She then raced back to the castle and started tearing through Kuroinu's forces. Once she reached the castle, Zafrina was met with a shocking scene. Her sister in all but blood, Chole, mind broken and covered in orc cum and her mother being raped by Volt and his men. The sight caused Zafrina to tap into the the Kyūbi's power and slaughter the Black Dogs.

In the end, Volt lost most of his men, his left arm and was forced to flee from the Dark Castle. After recovering from Volt's machinations, Olga and Zafrina spent a few months hunting down and eliminating the traitors in their empire. Volt was never heard from again, until now.

"Where?" Zafrina asks.

Olga closes her eyes for a moment before opening them. "The Elemental Nations."

Zafrina's eyes widen in shock.

"From what our spies say, Volt is somewhere in that region." Olga says. "He's been licking his wounds while gathering allies."

Zafrina clenches her fist. "Of all places..."

"Princess Zafrina Discordia." Olga says sternly.

Zafrina snaps out of her bad mood. "Yes?"

"Your task is to go to the Elemental Nations, find Volt and all those connected to him and end him once and for all." Olga says. "I would send others, but our own forces are low thanks to the traitors that were in our ranks. In addition, you are to gather allies of our own. Starting with Zabuza Momochi, the Demon of the Mist. He has been reported to be in Wave country at the moment and has been contracted by a despicable worm named Gato."

Zafrina takes a breathe before nodding to her mother. "Understood."

Seeing her daughters reluctance, Olga closes her eyes. "Zafrina."

Zafrina looks at her mother who motions towards her. The Dark Elf Princess then walks to her mother and is then caught in a loving embrace. Zafrina is taken by surprise for a moment before she begins to melt in her mother's arms.

"I know this is a difficult task for you." Olga says softly as she run her fingers through her daughters hair. "Going back to back to that world. But I have full confidence in you. Volt fears you. It is the reason why he's hidden himself until now. Trust your judgment. And prevent him from achieving his ambitions. We may not like humans, but no one deserves the vision Volt has for us all."

Zafrina hugs her mother as with a small smile. "Okay, mom."

Olga opens her eyes as she and her daughter part. The princess then leaves to make her preparations as Olga looks on.

"Be safe, my child." Olga says softly.

After making the necessary preparations, Zafrina journeys to the courtyard. On her way there, she passes by the remaining loyal members of her mothers empire. At first, many of the monsters treated Zafrina almost as bad as the villagers of Konoha. But the princess was able to win them over and they grew to like her not just as Olga's daughter, but as a friend.

As Zafrina exits the castle, she is met with two individuals seemingly waiting for her. One was a woman that can best be describe as an elegant, snow-white skinned, black-pony tailed beauty. She wears a white shirt, brown pants, black boots and a plain brown cloak. A sword can be seen hanging from her belt. This is Narberal Gamma, a doppelganger and one of the maids of the Dark Castle. The other individual was a voluptuous young woman with long, light pink hair arranged in buns and gold eyes with fox ears and a fox tail. She wears a Chinese qipao with a frontal cutout in a geometric fox-head shape and has earrings of the same design that shows off her lower chest, with a bell hanging from the center. This is Daji. Or as she's most commonly known as the Kyūbi no Yōko.

Shortly after Volt's attempt to seize the Dark Castle, Olga had finally managed to find a spell to safely separate the Bijuu from her jailer. Needless to say, Olga, Zafrina and Chloe were surprised to find out that the strongest of the Bijuu was a vixen. Daji had even commented that her other half was female as well and goes by the name Tamamo.

Although she comes off as professional and acts cute at times, Daji has proven to be very sadistic and has no remorse when taking lives. She takes great pleasure in making people suffer in any way she can. Daji is a captivating beauty who bewitchingly leads humans around by the nose, following her policies of free and uncontrolled wildness. She regards all human activity as filthy, but that doesn't mean she dislikes any of it. Some things are only fun because they're dirty. Daji had changed somewhat after seeing the life Zafrina had as a human. The vixen has grown to see Zafrina as a little sister and mate.

"Let me guess, mother sent you to accompany me?" Zafrina asks.

Narberal nods. "Olga-sama requested I accompany you on your mission."

"And you know better than to think you'll go anywhere without me, Frina-chan." Daji says with a grin. "Besides, this gives me the opportunity to see how my siblings have been doing." Daji suddenly gains a serious expression. "But I have to ask, what will you do should we meet someone from Konoha? Or more specifically, THEM?"

Zafrina closes her eyes as she thinks to herself. Daji had made a good point. Returning to the Elemental Nations means that she'll likely run into her former family. If someone were to ask Zafrina the same question a few years ago, she would've went into a raging tirade before breaking anything and everything in sight. But the Dark Elf Princess has changed since then.

"We'll cross that bridge when we come to it." Zafrina says as she opens her eyes. "For now, we have our assignment. Where is Wave country located?"

"On an island near the Land of Fire." Daji says.

"Reports say that that filth, Gato, has been bleeding the country dry of it's resources." Narberal says. "The humans live in a state of depression. A human named Tazuna is building a bridge that will connect the island to the mainland. Hence why Gato is desperate to eliminate him."

"I see." Zafrina says. She then takes a few steps past her companions. "Gate."

A reddish portal suddenly opens in front of Zafrina. The Dark Elf Princess looks towards her companions before looking back at the portal.

"Let's go." Zafrina says.

The princess, doppelganger and Bijuu walk into the portal. Not knowing that Chole was watching them leave.

"Be safe, little sister." Chloe says.

And done! The introductory chapter is finished. Rest assured, there will be some action in the next chapter. Where Zafrina will meet some new faces and old ones.
