Caius Gremory.

A boy with long crimson red hair and dark blue eyes can be seen smiling playfully at a handsome man with long crimson red hair like the boys, but instead of dark blue eyes the man has light blue eyes instead. The boy has sharp very handsome facial features that go splendidly with his red hair. The playful smile on his face makes him look quite adorable, a sight many women in his world are attracted to. However don't be fooled by his youthful face, In fact the boy is not a boy at all and is already 20 years old. Now for a devil 20 is still quite young, but no one would dare to call this young man boy because if they did, they might just lose their life. This is our Mc Caius Gremory and the man in front of him is his older half brother Zeoticus Gremory the current head of the Gremory clan after their mother handed over the title to Zeoticus.

"Caius, it seems that we'll go to war soon,." Zeoticus says in a serious tone.

"Finally! I've been itching for a fight." I can't stop the grin from spreading across my face.

Zeoticus sighs at his little half brother's actions.

Since he was a child Caius has really loved to fight ever since he could walk. He used to go around challenging everyone and anyone to a fight including all of the current Satans. Of course none of them took offense, after all he's just a kid, but what they didn't know was that Caius was born with control over terrifying black flames. The flames looked so evil and gave off this terrifying evil aura that could make the bravest person quake with fear. After the Satans heard of this, they all wanted to see his flames, so during a young devils gathering they held a competition between the strongest young devils and everyone that fought Caius that night left the arena with terrified expressions on their face. They all got a taste of that black flames and almost immediately quit when they realized the flames couldn't be extinguished. You see my brother Caius' flame cannot be extinguished no matter what you do, the flames will consume anything it touches until there's nothing left, magic, so don't hope to block the flames it'll eat through any shield you put up, honestly what a terrifying ability. The crazy thing is that the flames can only be stopped by Caius himself, The Satan's were really impressed by the flames, so much so that Lord Lucifer had given my brother's ability a name, he calls it The Eternal Flames of Hell. Caius has become very imfamous around the world because of his black flames. He earned the nickname Hell's Wrath because he delivers Hell's Wrath upon you when you fight him.

Caius Pov.

"Caius, I came to tell you Lord Lucifer has requested your presence." My brother informs me.

Oh what does that old monster want now. Lord Lucifer seems to have taken quite the liking to me, most likely due to my flames but it's not only him. Many devils have taken a liking to me, none more then the four great Satans, except they don't genuinely like me, they just want to use me in their plan to conquer the world.

I was actually surprised by how quickly I was able to master all of my abilities. Using observation haki I'm now able to see one second into the future, I can sense the presence, strength and emotions of anyone within 500km of me.

Honestly the Gura Gura no mi is really op, I can literally tear someone's body apart with my vibrations or quakes if that's what you want to call it, or to make it even easier I could shred their hearts with a punch, the possibilities are endless actually. I can clearly state that with all my powers combined I am a ultimate class devil, in fact I even have the confidence to take on the Satan's in terms of raw power alone but if we include other factors like experience and cunning well I'm light-years behind those old fogeys, they'd definitely be able to outsmart me. Observation Haki helps even the playing field a little, however it's not to the extent that I can confidently say that I'll be able to beat any of the four great Satans in a one on one fight.

The reason I've been able to so easily learn all of my abilities is probably thanks to my Gremory bloodline, our Gremory clan has always had excellent control over our power making it really easily to learn any magic or abities we have.

"Alright I'll go see him nii-san." I can't help but sigh honestly this old man is always bothering me, always calling me to his castle to tell me some bullshit or invites me over to hang out with his scumbag son Rizevim. I've never liked Rizevim he always gives off this creepy wormy vibe like he'd stab me in the back if my guard isn't up. I really don't like him, he honestly just creeps me out.

"Alright you better hurry up, he doesn't like to be kept waiting."

"Yea, yea." While I'm walking away, I suddenly hear Zeoticus ask me a question. "You're excited for the war aren't you?" Zeoticus asks.

I can't stop a sadistic smile from spreading across my face. Of course I'm excited, there's nothing better then the thrill and adrenaline rush you get when your fighting someone strong amd it's even better when you kill that person. Honestly I can understand why there's alot of battle junkies, the thrill of the fight is too addicting.

"I am nii-san. I can't wait to crush those arrogant angels, they think they're better then us, well I'll show them their nothing but a bunch of weaklings" I can't help but say scornfuly. Honestly Angels all have this holier then thou attitude and they always seem to have a stick shoved up their asses, while sneering at us devils. They're only that brave because they have the Big G behind them, without God they'd be pathetically weak.

Zeoticus let's out a sigh hearing my reply.

"Just make sure you don't die Caius." Zeoticus says in a serious worried tone.

"Huh I won't die nii-san, if anything you should make sure you won't die, considering how weak you are." I tell my brother sincerely.

Zeoticus' eye twitches hearing his brothers statement. Zeoticus isn't actually that weak he is a high class devil after all, but in this war he would be considered nothing more then stronger cannon fodder.

"Thank you for your concern." Zeoticus doesn't take offense he knows Caius is only concerned about him, Caius is just bad with words and normally speaks bluntly, but that's what many people like about him his brutal honesty, he doesn't even spare the Satans from his honestly.

"I'll see you later nii-san."

Lucifers castle is massive, nearly twice the size of ours and twice as intimidating.

As I approach the gate I notice an extreamly beautiful silver haired women with red eyes standing in front of said gate. The women is wearing a French maid outfit, her name is Grayfia Lucifuge one of the most powerful devils in the underworld.

I challenged her once and I lost miserably, but we became friends after that and I'd regularly visit her in order to get tips from her.

"Grayfia." I yell excitedly and tackle he. Ahhh Graydia's chest is honestly Heavenly, it feels like my heads resting on the softest pillows imaginable.

I can feel Grayfia's soft hand caressing the top of my head, it feels really good.

She's the one of the only people who are allowed to do that to me, if someone else tried they'd definitely lose that hand.

"Caius-sama it's good to see you aswell." I can hear the smile in Grayfia's voice. I pull away from Grayfia and admire her beauty. Honestly the anime doesn't do her justice, she's way prettier in person.

"Caius-sama follow me, I'll take you to Lord Lucifer." She gestures me to follow her and walks through the gate.

"So Grayfia what does the old man want?" I speak casually.

Grayfia doesn't say anything because she's already used to my way of speaking.

"I'm not sure Caius-sama." Grayfia answers with a polite smile.

"Urghh why are you so stiff Grayfia? Didn't I tell you to drop the Sama, aren't we friends?" I ask annoyed.

"We are Caius-sama but I'm working right now it's best that I keep things formal."

"Jeez, anyway when do you get a break?"

"In an hour Caius-sama."

"Great wanna fight, I think I can actually beat you this time." I ask smirking. I honestly believe I have a chance, especially if I use my barriers.

"Very well Caius-sama, I'll meet you at the usual spot." Grayfia smiles beautifully actually dazing me for a second.

"I'll see you there." I return her smile with one of my own.

Grayfia leads me to a big wooden door, the door that leads to Lord Lucifers office.

She knocks gently on the door. "Lucifer-sama Caius-sama has arrived." She informs the man inside.

"Send him in." A gentle voice comes from the other side of the door.

Grayfia opens the door and steps aside so I can walk inside.

"See you later Grayfia." I wave at her and walk inside.

Grayfia acknowledges my greeting with a nod and closes the door behind me.

I walk towards the massive wooden desk where a handsome silver haired man with Hazel colored eyes is sitting looking at me with intrigue.

"Hey old man what do you want." I ask annoyed because he interrupted my training.

Lucifer can't help but sigh hearing how Caius addresses him, but he's long since got used to it.

"I'm sure you've heard that we might be going to war soon."

"Yea, everyone whispers about it, but I can feel it war is in the air." A feral grin spreads across my lips.

"Yes you're right we'll be going to war with the Angels." The old man says drops the bomb calmly like he's talking about what he'd like for supper.

"So why'd call me? surely not to just tell me that" I ask confused.

"No, however we need you to kill someone, they have to be your top priority when the war starts." Lucifer squints his eyes and stares at me seriously, as he speaks in a grave seriois tone.

"Who?" I'm curious who they want me to kill.

"Azrael." He drops a bomb. Azrael the Angel of death, does this old man want me dead, is he afraid I might usurp him or something. Azrael is said to be able to kill his enemies with one swing of his scythe, he's a really dangerous foe, there's a good chance that I'd die if we fought, thats if I didn't have observation haki. As long as I avoid his scythe using future sight, I should be fine.

"That's all you called me for? I can easily kill that pompous ass Azrael." Actually I haven't met Azrael but I'm sure he's like any other Angel I've met.

"Good, good Caius, remember he has to be your top priority, he has to die no matter what." Lucifer stresses the urgency of my task.

I nod my head in response.

"Excellent, you may leave now."

"Alright I'll see you around old man."

That was honestly a waste of time, Azrael won't show up at the start of the war, he could've told me this when Azrael showed up, but maybe he wants me to prepare and with good reason. Azrael is supposed to be someone that can kill God himself, yea these old fogeys are probably hoping I'll die fighting Azrael. Well jokes on them, thanks to my Phenex bloodline I'm practically immortal, that scythe can't kill me unless I'm out of demonic power, there's also my Gura Gura no mi that gives me a powerful defense and offense. So I think I'm more or less prepared, but in battle literally anything can happen.

Anyway it's time I go meet Grayfia.
