I do not own any characters from either anime.
Soft foot steps echo of the walls of the hall, the crimson haired devil with steely purple eyes continue on his path through the expansive and Luxurious estate. The man wore over a fish net shirt a black cloak with red stitched in clouds, This was homage to his previous life before he was recruited to be something more than his mortal remains could fathom. He been dead for centuries now or he would have been if that man didn't reincarnate him on the day of his death from helping his fellow Uzumaki.
Life as a devil was quite an easy one, with his power he quickly raised to the rank of super Devil. He was greatly respected and fear throughout the underworld because of this.
He stops at a junction and stares forward at his friend and boss office. The two mahogany doors were fully closed and he turned to his right down another hallway. He came to a halt at another room lightly tapping on it before entering; a beautiful gray haired woman was seated at a desk. She was lightly brushing her hair while staring at her reflection in the mirror. He walked closer and stood behind her staying as silent as mouse.
"Nagato" The soft melodic voice was tantalizing on its own" have you seen my father yet?"
"No Grayfia" He walks closer and lean against the wall beside her desk.
"How long have you known?" She asks.
"For a while now, you're eyes betray you" He eyes her carefully taking in her features.
"My father wants us to marry" Grayfia places down the brush and met his eyes.
"I know" He hid the emotion from his words.
"I love another." She informs him.
"You do" He agreed, giving into the cat and mouse game.
She reaches over and grips his cloak "Will you kill him?"
Nagato stay silent pondering the question, part of him wants to without a doubt. Since he has been brought here from the elemental nations Grayfia has been his rock in a way. The only person beside her father he could count on without a doubt. She has quickly and readily placed herself as his best friend and probably only real friend here in the underworld. So it wasn't much of a doubt on why he fell for her in the first place.
"The one you love is the ace of the Anti-satan faction. I would be lying if I told you I hold no ill will towards him, so I will tell you this. Should Sirzech and I cross each other on the battlefield only one of us will make it out alive."
She release his cloak "I see than." Grayfia stood from her desk and stare into his cold eyes "I will not let you kill him Nagato."
The crimson hair god smirk "The matter of you letting me kill him or not is invalid in this case, the question is can you stop me?" He stood upright and began to walk away until a delicate hand grips his shoulder stopping him in place. He smiles at her show of power if only for a second.
"I know how to kill you Naga-Kun…I won't hesitate." Her voice was firm and unwavering very much unlike her eyes that so wanted to release the pent up tears at there corners.
Nagato stare forward at the wall before glancing back at her, letting his cold façade down if only for a second "You do what you have to… and I'll do what I have to." He continues on his path.
Nagato leaned against the wall of the office, His eyes hiding behind his crimson hair. The man in charge of the Satan army seated at his desk, drowning his sorrows in a bottle of wine.
"I can't believe she betrayed me Nagato… of all people my very own daughter for what? Some boy she has a crush on." She chose a stranger over me, her own family." The man looks up and tears fell from his eyes. He watch as Nagato didn't move a single muscle "You must be hurting as well Nagato. You two were inseparable when I brought you here from your home."
The crimson god frown "She was alone, she felt that no one really saw her for who she was, Grayfia not the Lucifer's daughter." He chuckle softly" That's why she clung to me, the guy who didn't know anything about Devils and there Hierarchy." He walks forward and places his palm on the man shoulder" Grayfia and I needed each other and that formed a powerful bond between us. She loves me but she love Sirzech more, nothing can change that. Besides she may not understand why this war will help in the future. The sacrifice you are making to end the Angels and there fallen brethren will keep and further the Devil Safety throughout the ages."
Nagato removed his hand" Grayfia is your legacy Lucifer, She will make the right choice whatever it may be."
Nagato stood at the front of the Satan loyalist formation. The remaining forces of the loyalist was dwindling down there numbers dropping like flies since Grayfia joined the enemy. She knew all about there army positions, strongholds, and supply routes it was only a matter time before the war made it to there front door now. Unfortunately for them the Crimson god was waiting for whomever to knock on it.
Nagato turns his gaze upon the approaching army, a crimson hair man at the front. He had a look of determination on his face. Nagato eyes fell at the man side, the woman he was supposed to marry at one point holding his enemy hand.
"Crimson satan." Nagato began" I heard tells of your exploits in this war."
"Crimson god, the fact that you know my name is an honor. We do not need to fight this day, just let me pass."
Nagato chuckle "Why would I let you pass to kill the man who saved my life?" The Ninja unbuckle his cloak half way as several small birds flew from underneath his sleeves "I'll let whatever deity you worship judge if you are good or not, I'll just arrange the meeting" His hands shot from underneath there sleeves with several Shuriken between his fingers. He let them soar starting the battle that will decided the fate of the underworld.
Sirzech raised his hands and several beams of red energy whip from his palms disintegrating the metal ninja tools. The beams of energy travel on only to catch and destroy Nagato cloak.
The ninja ran forward disappearing from Sirzech view only to end up behind him, who ducks the punch and retaliate by dropping to his knees and kicking Nagato feet from under him. He raised his palms and release an enormous wave of energy and watch as a log slowly disintegrate.
Nagato appear below foot raised and smashing into Sirzech chin up rooting him from the ground. A cold glint spark in Nagato eyes as he flash through several seals "Fire style: Grand fireball Jutsu" A huge ball of white fire exhale from his mouth. Sirzech watch as the ball of fire approach him before shooting a ball of energy from out his palm destroying and launching several more smaller orbs. Nagato frown before turning and running away. The orbs of destruction destroying everything they touch in Sirzech efforts of trying to kill him. Nagato spawn several arms from his back that launches rockets at Sirzech who jump place to place dodging the projectiles.
He refocus on Nagato only to see him standing still with his palm raised "Shinra Tensei!" A destructive force smashes into Sirzech sending him skidding back and slamming into the ground. He stood as a powerful aura surrounded him.
"You're ready to fight seriously Sirzech or Should I call you Satan Red now?" Sirzech stood up and ran forward kicking up a dust trail.
The man appears in front of Nagato with his fist raise, Nagato dance around the punch staying inside his guard. He grip up Sirzech extended arm and began pummeling the Devil in the face before tossing him over to his shoulder. Sirzech landed on his feet and landed a solid kick into Nagato gut sending him skidding back. Several orbs of Destruction following after the man forcing him to flip away from the dangerous energy attack. The ninja regain his composure only to be smash in the face with Sirzech fist rocketing him back. Nagato wipe his lip removing the blood and staring at his ragged opponent.
His eyes look around seeing his allies slowly but surely falling in battle, He held up his palm before cutting into his hand with a Kunai before tossing the bloody blade into the back of a random enemy saving his ally. Sirzech narrow his eyes on his enemy and watch as he dug around his hand pulling a shiny metal rod that was the length of Nagato arm out.
Nagato held the chakra rod at the ready before appearing beside the man utilize all his speed, Sirzech narrowly dodge a swipe before missing the second attack and being impale in his side below his ribs. The rod going straight through his armor like it was butter. He gasp in pain before retaliate with his fist which Nagato dodge and dance around before stabbing him again in his shoulder, Leaving the rod in place before kicking him away.
Sirzech skid before crossing his palms and unleashing a huge torrent of energy that smash into Nagato burning him greatly before he repelled it with a Shinra Tensei.
The two men breathe in deeply while staring each other down, Sirzech pull the chakra rod from his shoulder before tossing it away.
"I'm ending this war." Nagato cupped his hands together raising his chakra to the max "Perish from this world, Planetary Devastation" A small orb form between his palms before ascending into the sky. An invisible force grabbed at Sirzech trying to bring him to the orb. The earth rip up around him and flying into the orb as men and women from both sides screamed as they was pulled to the orb of destruction, only to be silence by more ground or trees and whatever decided to crush them.
Sirzech stare at the rapidly increasing ball of earth in horror as it grew even more humongous. He watch as it grew so big that it blocks his view of the sky. The miniature Meteor size ball of earth hovered menacingly above him and the few men that didn't get suck into the ball of death.
Nagato stayed silent and merely pointed his finger at Sirzech and the ball began its slow creeping descent "running won't save you."
Sirzech just stare in shock not seeing such an attack before. He just watches as death came closer and closer to embracing him.
The ball slowly to a haunting stop and Sirzech look forward only to see Nagato looking down at a Katana that was sticking through his chest. Small pebbles of earth fell from the ball onto the ground.
"You chose him." He could faintly hear Nagato speaking.
"…I told you, I will not you let kill him Nagato" She spoke the words softly.
Nagato chuckle to himself "Indeed you did" He coughs up blood that drips from the corners of his mouth" this is your father sword… You wish to seal me away?"
She smiles "You're right I can't kill you but sealing you away with my father sword is just as good…" Soft tears fell from her eyes.
"I see" He coughs again.
"Good bye…Naga-Kun" She whispers as his eyes closes, the last thing he seeing was Sirzech sorrow filled gaze.
1 Century Later
"Mom?" A little brown hair boy calls out. The boy got separated from his mother on there little picnic outing, when he ran to get Frisbee that went a little too far and into the forest. His mother calls out to him but he didn't really pay it much attention thinking it didn't go as far. Well that turn out to be false and this part of the forest was pretty damn dark as well.
He look around and his little mind was bring up ideas of all type of ghostly ghouls and creepy crawlies that's was running rampart in the dark recesses of the forest just waiting for him to stumble into them.
A low snarling drew his attention to a shaky a bush and he ran. He ran as fast his little feet can carried him until he fell over a man who was leaning against the tree.
He breathed in heavily "Oh sorry Mister…Ahhh" He shouted while scrambling back away from the pale looking skeletal man with dull stringy red hair. A long katana stuck deep through his back. What really got him was the look of sorrow imprinted on the man face.
The boy stood up and softly poke the man "Hey you okay?" He asks curiously not getting an answer. He frowns before standing "I'll get this sword out of you" He rose behind the man and grab the pommel with his small hands and tug it. The sword didn't budge an inch. He tried get with all his might a slow empowering sensation warm his belly and continues to pull at the blade and slowly felt it move from the man back. He kept going until it was all the way out and fell on his butt. The man skin began to glow warmly until it regain it fair color. His crimson hair regains its full color and his skeleton can no longer be seen through his skin.
The man slowly opens his eyes and the boy was the first thing he saw. A short brown hair boy with bright brow eyes and a kind smile. The image was greatly different than what he remembers seeing when he was sealed away. The boy dropped the sword and sat in front of him.
"You unsealed me." Nagato stated coldly.
The little boy nodded not exactly knowing what that meant but feeling like he accomplishes something. "Yeah"
"Than I am in your debt…What is your name?"
"Issei Hyoudo" The boy grin brightly.
Nagato closed his eyes before opening them again peering at the boy "Tell me Issei…Do you want to become a ninja?"
The boy eyes sparkle in delight.
