Our story begins here in the underworld in the Phenex household where young Naruto Phenex is found talking to his parents Lord and Lady Phenex. "WHAT DO YOU MEAN I AM BANISHED" yelled Naruto as stared in shock and rage at his parents decision. "Look Naruto I know this is upsetting but your the only Phenex in the clan that can't use fire magic" stated Lord Phenex. "I agree with my lord on this" speaks Lady Phenex, Naruto's mother and Lord Phenex's wife causing Naruto to stare at both of them in shock, sure he can't use fire magic but he has been trying his best to prove himself but always come short the only people that cared were his older Rabul (correct me if I got this wrong) his sister Ravel Phenex and Riser's peerage but his older brother Riser always picked on him and did his best to constantly beat down Naruto and make matter's worse they changed the contract between him and his friend Rias Gremory who he befriended for years to his brother Riser who sees her and his own peerage as nothing but sex slaves.

After constant failures Naruto was banished by his parents simply because they gave up on him and decided that in order to preserve their stature they decided to banish him and take his evil pieces as well thus unable to rank up through any rating games and have his own peerage. Lord Phenex had enough and had the guards escort Naruto to his room where he is to pack his things and leave. Naruto was simply dragged out without any fuss still in shock at his parent's decision. His sister Ravel begged him not to leave but he had no choice but he did promise that he would come back and beat Riser to stop the engagement between Riser and Rias no matter what and return. As he left he managed to steal back his evil pieces and left.

Months gone by as naruto journeyed throughout the underworld till his found and strange place, an old cavern which he used to sleep for the night unknown to him his destiny would change drastically.

Timeskip nightfall

Naruto had finished in making a fire when he suddenly sensed something both extremely powerful and similar to his family's powers so he decided to check it out he walked further into the cavern and then to his sock and awe he found something incredible. An actually Phoenix nest and it's supposed dead body, due to his shock he did not notice what little power he had resonating with the corpse which suddenly burst into powerful sacred flame.

As the flames died down Naruto could swear to the great Satan's that he seeing things cause in front of him stood an actual Phoenix. With a powerful cry the great fire bird spoke 'Who dares to- oh what have we here a child in my tomb who are you young one?' asked the Phoenix while Naruto after getting over his shock introduced himself my name is Naruto Phenex son of Lord Phenex or at least I was. "PHENEX YOU MEAN YOUR A CHILD OF MY LESSER KIN" roared for the spirit. Yes the very same but who are you? asked Naruto "ah has the 'mighty' Phenex clan forgot there creator already then again it has been a millennia since I have been seen alive very well my name young one is Phoenoxia the last true phoenix".Wait has in the true phoenix king that found our clan by offering the first Phenex devil one of his feathers and a sample of it's blood that Phoenix king?! 'yes the very one now tell me young one why are you here?' asked the spirit which leads Naruto to suddenly gain a depressed look on his face. I was banished cause I couldn't use any fire magic despite being a Phenex member stated Naruto (WHAT) yelled the spirit quite pissed at what he heard "child look into my eyes I wish to see you soul". wait say what?said a surprised naruto and a bit quite scared was the phoenix going to kill him. "now now be calm little one I merely have a look at what you endured" (If this child was truly abandoned by his own family I swear by all creation as my witness I will burn the whole Phenex household to mere dust) mentally growled Phoenoxia who was quite frankly pissed the hell off that these so called Phenex devils would abandon and banish a mere child for not having any form of there oh so precious power over fire. That however was going to chance right now, as naruto looked at the spirit in the eye he felt all his memories come forth.

The memories of his Riser mocking and beating him whenever chance he got, the pain of failure for not able to prove himself to his parents who banished him, the small peace he had with Riser's peerage who tried to help as much as they could, the friendship he had with Rias who above all else believed he could become a powerful devil despite his lack of his power over flame, the love of his sister and older brother who supported and comforted him in his times of need all laid before the great phoenix. When it was over he saw the spirit look at him with sadness and pity which ticked him a bit for the pity part at least. Then the spirit spoke "child you have suffered much yet still find love and light and even now you still wish to fight for your friends. Truly you are more worthy to be a Phenex than any of your household besides your sister true older brother and you wish to save your friend Rias Gremory from here forced marriage. As a scared being I take things as marriage quite seriously and I will not stand to such a front. Tell me child if I were to grant you great power would use it for your own gain and the suffering of others or use it to protect all those you love with all your heart and soul'? askedPhoenoxia

Naruto looked at him straight in the eye and with a pure convinced voice said "your damn straight I am going to protect my friends even if it's against my family I will all I can and more if means to protect the ones I love cause I will never die or give up if they are in harms way that is a promise of a lifetime dattebayo". The spirit looks back a bit stunned at Naruto's forwardness but merely shrugged it off while nodding his head in approval the phoenix soon gives Naruto an offer he can't refuse. "child you truly have a pure heart and a righteous mind worthy of a phoenix which is why if accept I will grant all my power over the phoenix flames and teach you everything I know to master it. The question is due you accept for doing so I will crown you my successor and my son if you wish it so. Do you Naruto Phenex accept this offer I give to you?" Naruto stood stunned for the chance to finally prove himself and get the strength to save his friend Rias was in his grasp, his chance to prove his family wrong and save Riser's peerage from their own corrupt king and take them as his own like he promised would be fulfilled, just this one answer would change not just his life but the whole underworld and he immediately responded with one easy answer. "I accept!"
