"So... What is she like?" A small girl asked Naruto who was standing in front of her desk. She has soft blue eyes and long silver flowing hair. She is wearing a dark-blue one piece dress with a white collar design of two long triangles and dark blue Cornette with a heart decoration. Around her neck was a necklace with Naruto's duplicate key hanging in the middle.

"It still bothers me that you're wearing a nun's clothes.." Naruto commented on her outfit.

"You are dodging my question. Tell me about that Lucy girl." She demanded for answers. "And I don't tell you how to dress.." She murmured.

Naruto sighed "What do you want to know?"

The girl's eyes burned in jealousy. "Everything."

Chapter 4: Black & White

Earlier..

The explosion blew a large hole in the their cart. The smoke cleared revealing the people inside the cart unharmed and was protected by a golden transparent spheres.

Gabriel sighed in relief as she casted the spell at the last second. "What happened?"

Naruto's eye twitched when he saw the attackers. Outside the train was two small girls, floating and looking at him with an emotionless look. They both have gray eyes, black hair, pointy ears and wearing a black gothic lolita dress. The only difference are their hairstyles. One is straight and the other is done in a pony tail.

"Nee-sama, Nee-sama. Naruto-sama has found some new pets." The one in a pony tail deadpanned as she looked at the girls around Naruto.

"Yes, I think you are correct Lilith. Master has replaced us with those slutty big boobed girls." She replied, still no emotion coming out of the two.

Lucy looked at Naruto with an annoyed look because of the little girls comment about her being a slut, "Who are they? And why do they know you?!" She asked Naruto who pinched the bridge of his nose.

"We are Naruto-sama's pets. Please refrain yourself from talking to Naruto-sama that way or we will have to exterminate you." Lilith said coldly.

"..You are a pervert aren't you." Lucy glared at Naruto.

Naruto sighed in annoyance. "This is infuriating.. Ophis, Lilith, What do you guys want?"

"YOU'RE NOT DENYING IT?! HENTAI! LOLICON!" Lucy shouted at Naruto.

Ophis agreed with Lucy. "You are correct. Master is the Loli master."

Naruto groaned and starts explaining. "If you define a pet, A pet is something that you take care of. Those two-" Naruto pointed at the two girls. "Are my pets. I feed them and give them home. They are basically freeloaders. All sins have a pet and those two are mine."

The two girls hovering outside the train blushed but still had a stoic look on their face.

"Nee-sama, Nee-sama, Naruto-sama said that we are his."

"Indeed, Master has finally confessed his love for us."

Gabriel smiled at Naruto "Can I be your pet too?"

With a face palm in the face, Naruto groaned. "Just tell me what you guys want."

"Trihexia-sama wants to see you." They both said at the same time.

Lucy looked at Naruto with wide eyes. "Trihexia? You mean-"

"Yeah. My boss. Now if you could excuse me-" Naruto disappeared in a blink of an eye.

The girls that attacked them vanished at the same time. Erza and Gray looked at Lucy causing her to gulp. She had a lot of explaining to do.

Underworld, Trihexia's Mansion

Naruto arrived in a room that was full of runes beneath him. Beside him was his two adorable pets, clinging on both of his arms. "Infuriating. Both of you." He sighed and struggled to walk outside the room.

"We do not agree about you replacing us." They said at the same time.

"I'm not replacing you. Those are my new friends..?" He stopped walking when the twins stopped and looked at each other.

"Nee-sama, Nee-sama. Naruto-sama said he has friends."

"Indeed. It is the first time I hear master made a joke."

"Infuriating.. I have friends.. maybe? ANYWAYS what does Hexia want?" He asked the twins.

Ophis and lilith looked at each other once more before nodding then dragged him towards Trihexia's office. Like in the human world, Trihexia's office looks like a principals office.

Ophis and lilith knocked at the door before bowing at Naruto and leaving him in front of the door.

"Come in."

Lucy sighed as she finished explaining about the truth. "So please don't tell anyone!" She begged Gray and Erza.

"So you're planning to collect all these keys to bring your mother back?" Erza asked Lucy who nodded at her.

"Yeah.."

Erza smiled and crossed her arms. "I don't see any problem with that. Your secret is safe with us, right Gray?"

"Yeah. I still can't believe that Naruto is a devil."

"And I'm sure Natsu will keep it a secret as well." Erza added while looking at the unconscious pinkette. "But you need to tell master. He can help you with that. Maybe he has information about these keys."

Lucy teared up from happiness and bowed her head. "I will! Thank you!"

"How many keys have you found?" Erza asked Lucy.

"Three." She placed Naruto's, Gabriel's and Lust's keys in the table."This one is Naruto's" She pointed at a demonic looking key.

"And that's my key!" Gabriel smiled on pointed at her golden key.

"... GABRIEL IS A SUMMON?!" Gray pointed his finger at Gabriel.

"Ahe.. I forgot to tell you about that." Lucy chuckled nervously. "She is a Zion angel."

Gabriel gave them an angelic smile. "That I am. It's my first time being summoned here so please show me around!"

"Due to an attack, the train will stop at Onibus. We are arriving in a few minutes."

"That's our stop." Erza said then smiled at Gabriel. "We still have time to admire the place before we get going."

"Ah! Thank you Erza-san! You're such a nice soul!"

They arrived at the station and started heading to a restaurant to eat lunch. Erza started showing Gabriel around and teaching her some new things.

"What weapons do you use Gabriel?"

Gabriel placed a finger on her chin. "I'm not into weapons but I use this for emergency." She summoned a golden sword that glows with holy power.

"Onii-sama gave it to me for protection. It's called the Excalibur!" She said happily as she show the sword to Erza.

Meanwhile the redhead has star in her eyes as she gaze at the beautiful weapon. "That's an amazing sword Gabriel!"

"Thanks!" She smiled at the compliment while the golden sword vanished in thin air.

Lucy was curious about Gabriel's sibling and decided to ask her. "You have an older sibling?"

Gabriel nodded at her "Yes! He's name is Michael. Onii-chan is soo cool! Unlike me, He's a fighter! He's good at swords and stuff!"

"He sounds amazing." Lucy imagined the appearance of Michael in her head. A long haired blonde like Gabriel wearing a shining white armor.

"He kinda looks like Naruto-kun too. Strange.." Gabriel scratched her chin then shook her head. "I am going to ask what is the reason we left Natsu-san in the train?"

All of them looked at each other then their eyes widened in shock. "WE LEFT NATSU IN THE TRAIN!" Lucy shouted.

"I was busy showing Gabriel around that I forgot about Natsu! It's all my fault! Somebody hit me!" Erza balled her fist.

"I can get Natsu. I am one of the fastest flyers in heaven!" Boasted Gabriel with a gentle smile. She then let her 12 beautiful wings out, making Gray, Erza and everyone near them looked at her in awe.

Erza bowed her head at the blonde angel. "Please get Natsu back!"

Gabriel nodded "I will be back in 20 seconds." She flapped her wings making a huge gust of wind and creating a sonic boom in mid air.

With a speed of mach 10, she arrived at the fast moving train that is heading towards the next town for repairs.

She landed inside the hole that was created by those Loli earlier and saw Natsu being beaten by a guy.

"Eh? another Fairy brat?" His eyes trailed to her wings then grunted. "Looking at your appearance, You might be an S-class. Tsch! I'm out of here!"

"O-Oy! D-Don't run from me!" Natsu shouted while struggling to get up. Somehow Gabriel's cure didn't last for long.

Gabriel frowned and looked at the unknown mage. "You have something powerful inside your pocket."

The shadow user smiled nervously. "W-What are you talking about?"

"I sense a dark magic.. Are you a mage of Eisenwald?"

He smirked "I'm glad you knew-" He tried to move but he was paralyzed. "W-W-What's going on?!"

Gabriel pouted and walked towards him. "You guys want to use the song of the children to hurt other people. Unforgivable!" She plucked a feather on her wing and placed it on the mans forehead.

"I shall cleanse thy soul and confiscate that dark item that you are hiding."

The shadow mage fell unconscious and drop on the ground. Gabriel bent down and grabbed the dark item in his pocket.

"A flute?" She looked at the scary item in her hand. It has a skull with three eyes on one end, and an oval-like cutout in the skull's brow. On the other end, there are root-like cutouts.

"W-What did you do to him? T-That was amazing! And since when did you got wings?!" Natsu tried to grin but failed. The train was still moving and his sickness is getting worst by the second.

"I wiped out his memories using my feathers. About my wings, Lucy-sama will happily explain it to you!" She smiled then quickly panicked and rushed towards Natsu.

"I'm sorry! I was so caught up about stopping the bad guy that I forgot your situation!" She placed a hand on his forehead and it glowed gold.

Natsu suddenly felt his energy coming back to him and his headache disappearing. He stood up and flex his arms. "Thanks Gabriel!"

Gabriel nodded and smiled at him. "We should get going. It has been more than 20 seconds now and I must apologize to Erza-san because of that."

She grabbed the back of his shirt and flew back to Onibus in the speed of sound.

Onibus

Gabriel arrived at the station with a grinning Natsu who has a very wild hair because of the wind. "That was AWESOME!"

Gabriel Retracted her wings and it vanished like magic. "I am glad that you enjoyed the flight."

"Natsu! Are you alright?" Erza ran towards the pink haired teen.

"Yeah, Gabriel knocked out one of the eisenwald guys! It was awesome!"

Erza quickly started shaking him madly. "DID YOU INTERROGATE HIM?! DID YOU ASK ABOUT LULLABY?!"

Lucy sweat dropped at the scene and walked towards Gabriel. "What happened back there?"

Gabriel took out the flute out of her pocket and showed it to Lucy. "I found this in the guy's pocket earlier Lucy-sama. It has a dark aura surrounding it."

Lucy's eyes widened in shock. She thought that flute was just a myth and just folktales to scare the childrens. "T-That's Lullaby! The cursed song!"

Gabriel looked at the flute and frowned. "So this is the weapon.. Shall I dispose of this instrument Lucy-sama?"

Lucy looked at Erza who nodded at her. "That's our priority in the first place. We need to destroy it."

"Go for it Gabriel." Lucy told Gabriel.

Gabriel placed it on the ground and took a deep breath. Behind her, Lucy, Erza, Gray and Natsu waited for her to cast a spell to destroy the death flute.

"Begone!" Gabriel shouted while stepping on the flute repeatedly.

All of them sweat dropped at the blonde angel. "Do you have any more effective way?" Lucy asked Gabriel who was starting to get exhausted.

"I-I believe I have." She said while catching her breath. "I need Naruto-kun to massage my breasts after this." She sighed to herself. Luckily Lucy and Erza didn't heard her.

She clasped her hand together and it started to glow. "Vanish-" Before she start chanting a spell, The flute started oozing purple smoke.

"I will not let you destroy me!" The flute said and a huge magic circle appeared above them.

The people in the station started panicking and ran away from the scene. The flute turned into a gigantic beast that is 50 meters tall and destroyed some of the building in process.

"Gabriel!" Lucy shouted at the angel and nodded.

She cancelled her purification spell and let her wings out. She clasped her hands and prayed."Protect the people, Guardian Angels!" Some of her feathers scattered and turned into angels in white armors. The white knights started picking up the civilians and flying them away to safety.

"I'll start with you!" Lullaby lifted its foot and smashed it in Gabriel's position. "You dare stepped on me?! I'll step on you!"

Gabriel bit her lower lip and extended her arms forward. "AEGIS!" A golden sphere surrounded her and shielded her from Lullaby's attack.

"Lucy-sama! Please get away from here!" she shouted at Lucy.

"No! We will help you fight that thing!" Lucy shouted back. Erza, Gray and Natsu smiled at her. "We are mages of fairy tail and we never leave someone behind!" Natsu shouted and ignited his fists.

"That is correct. We will help you in this battle Gabriel. Requip!" Erza requipped in her heaven's wheel armor.

Gabriel managed to gave her a smile. "You looked like an angel Erza-san!"

"Enough talking!" Lullaby quickly blow a tune that paralyzed them except for Gabriel. She quickly flew towards her friends and cast aegis again to buy her time as she healed them.

Lullaby started smashing the shield and it started to crack a bit. Gabriel healed Lucy first then went to Erza.

"Tsch! Where is Naruto when you need him!" She grabbed Naruto's key and did a swiping motion. "Open gate of hell! Wrath!"

But Naruto didn't appear like he always did. Hearing another cracking sound, She grabbed the new key she acquired back in her first mission.

"Open gate of the virgin! Vrigo!"

A maid appeared with shackles around her wrists, short Blonde hair, and blue eyes. She wears a typical maid outfit, consisting of a black under coat and a white, frilled-trim apron.

"Eh?.." Lucy blinked in shock. This was not the Virgo that they fought back in the mansion.

"You called Mistress?" Virgo bowed her head at Lucy.

"W-WHY ARE YOU BLONDE?!" That was the first question Lucy asked.

Virgo smiled and happily explained. "I am a stellar spirit that is loyal to her Master. I carry out my duties in the appearance desired by my Master."

'Desire?...' Lucy thought of Naruto's blonde hair then blushed. "C-Can you turn your hair back to pink?"

"Of course." Her blonde hair turned into pink locks. "What else do you desire Master?"

Lucy looked at her teammates and they are already healed. "Help us fight that demon."

"Yosh! Let's beat this wooden thing into a table!" Natsu grinned and charged towards Lullaby but was blocked by aegis.

"Itai!" He cried in pain as he hit his head. Gabriel quickly flew towards him and heal his bruise.

"Are you guys all ready?" Erza asked as she prepared her swords. They all nodded and prepared to fight.

"Gabriel, can you remove the shield?" She asked Gabriel who nodded her head. "Deactivate!"

Aegis shattered and the Mages of fairy tail charged the demon. While they fight, Lucy stayed in the ground with Gabriel, watching them fight the demon.

"I wish Naruto-kun is here.." Gabriel frowned.

Lucy frowned too. She felt useless. Sitting there, doing nothing and just watching them fight. She made up her mind and ask Naruto to train her when he returns. She wants to be strong to be able to protect all her new friends. She's not the princess who grew up in luxury anymore.

Gabriel watched as Erza got swatted away by Lullaby's hand and quickly flew towards her and caught her mid air. "Are you alright Erza-san?"

"Y-Yeah, Thanks for the save." Erza smiled weakly as Gabriel started to heal her.

Back in the ground Lucy bit her lower lip. She watched as her friends trying to dodge Lullaby's attack while attacking its blind spots. Her hand slowly traveled to her keys and picked up Lust's key.

She stared at the key for a second before making up her mind. "Please help us." She used the sharp edge of the key to slice her palm and let her blood coat the key. They glowed pink indicating that it is ready for use. She took a deep breath and did a swiping motion.

"Open gate of hell! LUST!"

Underworld (Current time)

"Aand she's basically like Layla." Naruto finished explaining to Trihexia.

She started to give a smug look on Naruto. "See? That girl found a new guy after you guys break the contract! Ha! I told you that she only likes you for your looks!"

"I do not own her and she is free to choose who ever she likes.. And besides, I'm a devil. I have jobs to do." He said with a little sadness in his voice.

Trihexia held up her hand to Naruto with a smile. "Then be mine, Naruto!"

"I refuse."

Trihexia sighed in defeat as she slumped down her chair. "Foiled again.. Is it because I look like a child?" She asked sadly.

"No, Because you're my boss." Naruto deadpanned.

"Then if I retire-"

"Why do you need to speak with me? Time moves slower here so I need to get back as fast as possible."

Trihexia pouted at him. "You're so attached to that Lucy girl because she looks like Layla. hmph! I have a job for you because you're the only one who is summoned right now."

"What is it?"

Trihexia snapped her fingers and a hologram of five gems. "We found the God key and we need these gems to unlock the seals surrounding the catacomb."

"What gems are these?"

"These are the gems of the five Dragon Kings. Tiamat the chaos karma dragon king (Blue gem), Igneel the fire dragon king (Red gem), Acnologia the black dragon king (Black gem), Albion the white dragon king (White gem) and last is Fafnir The Gigantis dragon king (Gold gem). Take your time, these gems can shift into different type of items so they might look different at first. The only Dragons that are alive and roaming are Tiamat and Acnologia so keep an eye on them."

Naruto pinched the bridge of his nose. "Why do we need the God key anyways.."

Trihexia smirked at Naruto. "It's a secret Naruto. But you'll find out in the future. Now go and bring me back these gems."

Naruto prepared a portal next to him and before he could leave, Trihexia shouted "Don't forget to visit me or I'll drag you back here!"

"Hai hai."

As soon as Naruto left the room, Trihexia smiled and placed a hand on Naruto's spare key. There are so many secrets surrounding Naruto. But she can't tell him yet.

She closed her eyes and took a deep breath. Once she exhaled, She saw a vision. A small glimpse in the future. Everything is on fire and everything is destroyed.

Naruto was heavily wounded and looking up to a figure with black wings. The figure has Black flowing hair and Red glowing eyes. On top of the figure's head was a Red halo that was sparking with black and red electricity.

Trihexia opened her eyes and realized that she was breathing heavily. This was the first time she saw a vision and it was horrible.

"I-I.. I need to find out who that dark angel was.."

Back at Naruto

Naruto arrived in front of a two story house using the portal. It looked modern and it was the place he called home. He needed to check something important before leaving the underworld and be at Lucy's side. Naruto entered the door and was greeted by the twins.

"Welcome home Naruto-sama."

"Welcome home Master."

They greeted at the same time. Naruto sighed and patted them in the head. "I'm actually happy that the house is still in one piece."

"Of course we would take care of the house while you are away master." Ophis hugged Naruto's left arm.

"We don't want you to be mad at us when you return and the house is messy." Lilith hugged his right arm.

"Why are you all so clingy?" Naruto tiredly asked the twins who both glared at him.

"Because those big boobed sluts might steal you away from us.." They both deadpanned.

"Infuriating." He walked towards the kitchen then sighed again when the twins let go of his arms and started to walk behind him.

Naruto looked at his double door fridge for a moment before opening it. "Why am I not surprised.."

The fridge was empty. Not even a trace of ice was left in the freezer. he looked behind him and the twins started to point at each other.

"It was her." They both said at the same time with the same tone.

"This was full before I left.."

"Welcome back nya~" A black cat entered the kitchen via window. She then transformed into a beautiful and attractive young woman with a voluptuous figure, long black hair with split bangs, and hazel gold eyes with cat-like pupils.

Her attire consists of a black kimono, a yellow obi, a set of golden beads, and an ornately detailed headband. The kimono features a red interior and it is open at her shoulders, giving view to her enormously large breasts,

"Kuroka? Why are you here?" Naruto asked the black haired beauty. Then he raised a brow at her. "And where's lust?"

If her pet was here, then lust is going to jump out out sooner or later.

"Master got summoned nya~ And you know she wants you to call her by her name." Kuroka purred and walked towards Naruto while shaking her hips.

"That means-" Naruto's eyes widened and tried to make a portal. "Infuriating!" He entered the portal leaving a disappointed Kuroka behind.

"Mou~ I want to spend time with Naru-kun nya~"

"Nee-sama, Nee-sama, A stray cat has found her way to our house. What should we do?" Lilith asked while looking at Kuroka.

"I think It's best to kick her out before she touch master with those dirty paws of hers."

Kuroka's eyes started to twitch in annoyance. "So you two think you can take me on flat breasts?"

"We do not fear you, stray cat." They both said at the same time.

He exited the portal and arrived in a badly destroyed train station. Lucy, A new pink haired chick, Erza, Gray and Natsu looked like they just had a hard fight, save for Gabriel who was unscratched and healing them. Behind him is a giant burning thing and a woman covered in black lightning with a sadistic smile etched in her face.

"Ara, I was expecting you, Naruto-kun~"

Akeno won the poll by a landslide! A little short chapter. It stopped actually on 3,999 words.
