[Crossover] The Uchiha Rescue Plan

Announcement: After talking it over with my editor, I've decided to start charging for the story on February 19. There will be three chapters that day. I hope you'll support me, little angels~ Blurb: How to save the Uchiha from their tragic fate at its roots Founder Arc Yuan Chu had lived with this embarrassing name for over twenty years. Only when the Emperor bestowed a surname on him did he realize something was off. The name Uchiha seemed vaguely familiar... So the red-eye episodes that he and his children occasionally suffered from weren't hereditary illnesses, but the so-called ninja bloodline ability, the Sharingan? Having learned that the original story ends with nearly the entire Uchiha clan wiped out, this winner in life declares: I'm not satisfied with that ending! So let's just be proper nobles and enjoy ourselves, hahaha. Why become ninjas? Heh heh heh. [Evil laughter] Father Arc Tajima is a transmigrator who has arrived in a powerful clan in the ninja world. Going by the usual script, Tajima should be crushing ninjas, kicking nobles around, and unifying the world. Unfortunately, the sworn enemy clan next door has a clan head who seems even more like a transmigrator than he does. Unable to beat them in combat, Tajima can only develop other talents, and somehow ends up restoring his ancestors' glory. Founder Arc The final boss of the Fourth Shinobi World War is reborn as a child. His parents are both alive, and his brothers are all here. At this point, he hasn't yet met his childhood friend, whose boundless love will ruin half his life. So, having a little brother is all you need. What good is a childhood friend? Can you eat one? Clan Head Arc He wakes up to find that his home has changed from the Uchiha compound to Konoha's orphanage. The future Uchiha clan head says his heart is practically shattered. Back at the Uchiha compound, the future Yellow Flash and the protagonist's dad ask: Is it my fault? #Every month, there are a few days when I switch bodies with my friends# Theme:
