[Crossover] The Perfect Ending Must Be Achieved

You head out to get the basic food you need to fill your stomach. "What rotten luck! I run into this jinx first thing in the morning." A piece of fruit smashes hard into your head. Disgust / fear A park, where people hide in shadowy corners to watch the show. You gather your courage and step forward. "Get lost! You fatherless, motherless freak! Only a ghost would play with you!" Malice / showing off An old man, hunched over, leads a timid child along, repeating words like these again and again. "Where the leaves of Konoha dance, the Will of Fire burns. The whole world must inherit the Will of Fire!" Hypocrisy / brainwashing Uzumaki Naruto's life was a joke. As a child, everyone treated him with malice, fooling him into shouting like an idiot that he would become Hokage. The boy pursued teammates who were loved by everyone and solved calamities that even the Kage could not, only to finally claim the glory that should have been his all along. But it was as if Uzumaki Mansei was not allowed to be loved. The fearful looks people gave him were mixed with hatred, while those who had once beaten the "hero" were itching for another chance. "Serves you right!" "A monster is always a monster!" "To be honest, it bothers me when you like me! So please stay right where you are, okay?" The first girl who ever smiled at you sealed your chakra. Her emerald eyes were full of malice, and the ninjutsu she used was far beyond anything she should have been able to handle. Konoha, which had always loved peace, was the first to break it, starting the Fifth Shinobi World War. They looked certain of victory, as if they had nothing to worry about. The enormous Nine-Tails rampaged across the battlefield, firing Tailed Beast Bombs in a frenzy. Konoha soon annexed the four great nations, weakened after the Fourth War, and emerged as the final victor. Once the fruits of victory had been claimed, the docile Nine-Tails suddenly went berserk and chose to self-destruct without hesitation. From that moment on, there were no shinobi in the world, and no humans. When Uzumaki Naruto, after self-destructing, woke again, his name was Mansei, a tool who survived on sin points. Naruto from a parallel world: blond and ordinary-looking before being reborn, red-haired and stunningly beautiful as Mansei after being reborn. Conspiracy theory: Before he was reborn, the Third Hokage was Danzo, who was determined to turn Mansei into a weapon of Konoha. After he was reborn, things are just like the Naruto we usually watch! The protagonist is ill, the protagonist is ill, the protagonist is ill. He doubts himself, and his imagination runs wilder than the plot.
