[Everyone Reads Too Much Into Everything] + [Trait Editing] + [Lighthearted Comedy] + [Invincible Puppet Master]
After transmigrating into Naruto, Qianye became an utterly ordinary chuunin teacher at the Ninja Academy. He thought he would have to scrape by in this dangerous world, but then he awakened the [Everything Trait Editing System]! By spending Emotion Points, he could freely change the attribute traits of anyone or anything!
Seeing Naruto, the boy shunned by the villagers and called the Demon Fox, Qianye casually erased his original [Demon Fox Incarnation (Black)] trait and replaced it with [Nine-Tails' Dear Old Dad (Gold)]! The next day, the Nine-Tails was lying at Naruto's feet, wagging its tail and lighting Naruto's cigarettes. The entire village was dumbstruck!
Seeing Sasuke, consumed by revenge and weighed down by bitterness, he changed the [Avenger] trait to [Ultimate Big Brother Complex (Gold)]! Sasuke: “Only Big Brother Itachi gets to kill me. Everyone else, back off!” Itachi: “You foolish little brother... Wait, don't come any closer!”
Seeing the Third Hokage, who wore a false smile and mouthed off about the Will of Fire, he changed [Ninja Hero] to [Ultimate Scapegoat (Gray)]! The Third Hokage: “I'm not taking the blame for this!” The villagers: “Yes, you are! You did it!”
Years later, when the Otsutsuki arrived, Qianye glanced at the [Forebear of Chakra] trait above Kaguya's head and quietly changed it to [Wife].
“Um... Kaguya, isn't dinner ready yet?”
(This book has a bizarre sense of humor. If you don't laugh, come beat me up through the internet!)
