Prologue
Fuming with anger, hatred and pain, Naruto Uzumaki confronted his former friend, Sasuke Uchiha, ready to beat down and torture his former friend in the most brutal way possible, wanting him to pay for all the suffering that he put him through, Naruto charged into the Uchiha and stroke him down with a rasengan in a fit of extreme rage.
"You, you ungrateful... after everything I did for you... I gave you everything, my friendship, my loyalty, my dreams, and you just kept taking, until now I have just about nothing left, not even my own teacher." said Naruto while grieving in pain and bawling out.
"Naruto, like I said before, you never had a family to begin with, you were on your own right from the beginning, you can never understand what it is like to..." said Sasuke in a pretentious manner.
Naruto was now furious and filled with anger, using the power of the nine tails, viciously slapped Sasuke in the face before he could finish talking.
"SHUT THE HELL UP YOU ENTITLED PARASITE!" shouted Naruto in an extremely furious, savage tone filled with malice and anger.
"Oh, boo hoo, my family and clan are all dead, nobody can ever understand poor little me, feel bad for me" said Naruto in a hateful, mocking tone of voice.
"Screw you, you vile, backstabbing serpent, you were loved by everyone, everyone felt pity for you, while I was the one who suffered throughout my life, never given any kind of love during my childhood, almost everyone hated me, thought that I was a monster that needed to be executed, you could never understand what it means to be hated by anyone, you always take everything for granted like an opportunistic and greedy little fiend, I hate you, I really hate you" said Naruto, trying to pour in as much anger in as possible to convey how much he feels about his former friend.
"I... I... what? I did not... what?" said Sasuke in bewilderment at Naruto's sheer rage filled anger.
"Save it, I do not need any apologies from a worthless slave of Orochimaru like YOU! you are nothing but an abomination, undeserving of forgiveness and I shall send you back to the cold wasteland from whence you came" said Naruto, who then uses frost style jutsu to expel from his mouth a massive blast of freezing ice at Sasuke with intent on freezing him solid, but Sasuke dodges it in time, enraging Naruto, who is now hellbent on making Sasuke suffer as much as possible.
"SASUKE! YOU CANNOT ESCAPE MY WRATH! I WILL HAVE MY REVENGE!" screamed Naruto who then started rapidly firing balls of ice at Sasuke, who kept dodging them until finally getting hit by one, sending him flying, which pleased Naruto, who then ran to Sasuke and started throwing haymakers into his face with truly sadistic glee and then beating his face in the ground.
"I'll make you suffer, I will make you cry blood, I will make you scream, I WILL MAKE YOU PAY!" said Naruto, who then grabbed Sasuke by the throat and flung him right into a wall, Naruto then prepared to kill Sasuke with his rasenshuriken, but his attack was blocked by Sasuke's Susanoo, which made Naruto get far angrier and start to break apart mentally.
Naruto then immediately turns into his nine tailed beast form and started to attack savagely at Sasuke with animalistic fury, but his Susanoo was too strong for him to break into, and then Sasuke makes matters worse by engulfing Naruto in Amaterasu flames, making him scream in agony and cause Naruto to finally lose it.
With one great roar, Naruto's sheer anger and hatred was so great, the ground below trembled, and he begun to channel in the powers of hell itself, soaking the nine tails chakra back in and seemingly reverting back to his normal human form, only for the earth to split open a hole which connected the world with the first circle of hell itself, Limbo, of which causes the sky to be blackened with its primal darkness.
Naruto siphoned up the infernal energy, merging it with the nine tails chakra to fuel his new mutation, growing a long tail, rows of sharp teeth, sharp claws and course hair all over his body as he moaned in intense pain from the transformation.
Then, several more holes erupted from the circles of Lust, Gluttony, Greed and Anger, which caused tornados to start appearing and wreaking havoc, infernal monsters of hell to be let loose into the world, swarms of mosquitos to spread across the sky and all of the water becoming polluted sludge.
Naruto siphoned off the infernal power, physically growing four more tails in the process, and growing larger, tearing his jacket and shirt apart in the process, with his mouth mutating into monstrous jaws filled with rows of razor-sharp teeth, and his eyes becoming slit and demonic as well.
"What... what the hell is happening?'' said Sasuke, who then shed a tear, horrified at what is happening.
Then, three more holes erupted from the ground from the circles of Heresy, Violence and Fraud, causing wildfire to ignite and spread across the land, the water to turn into boiling blood, and snakes to start slithering about from their hiding places and start attacking maddeningly.
The increasingly toxic energy made Naruto become more hideous, his head becoming larger and more like a horrific toad with ears like the nine tailed fox, his arms becoming massive with extremely long, curved claws, and grow three more physical tails from his body as well.
And finally, the final hole erupted, this one from the ninth circle, Treachery, Sasuke's biggest and worst sin ever, and the ferocious energy of the circle has caused the world to be engulfed in a horrific blizzard, the primal evil energy completing the transformation of Naruto into a hideous monster, who resembled a horrific mish mash of fox and toad with massive claws, rows of sharp teeth, a putrid stench from his course, slimy hair, horrific slit eyes and nine cancerous looking tails as well.
"Naruto? Naruto? what... what have I done?" cried out Sasuke in grief while being so horrified at Naruto's new form that he is literally both urinating and defecating himself uncontrollably in his pants, Sasuke is horrified at the monster that he had accidentally created.
