After many years of training his disciples, he is killed at the age of 60 by the ploy of a secret organization and was reincarnated in another world with all his past memories.Though he was surprised by the magic and the strange species of that world, he adapted very fast to his condition as a newborn and took advantage of it. He acquired special magic and gained a massive amount of strength thanks to his tight discipline in order to reach his goal: resume his career as a teacher which he left halfway through in his previous life.This is the story of a man who based on the memories and the experiences of his previous life, became a teacher who travels through the world with his new students.

Crossing to the Naruto World, Uchiha Tonan obtained the ‘Legacy Inheritance System’. As long as the people who acknowledged him died, he could inherit all abilities of the deceased.

Therefore…

“Konoha’s higher-ups mistreated the Uchihas. So, I’ve decided to lead the clan to launch a coup d’état after three years.”

“Ding! Gained Uchiha clan’s acknowledgment.”

Two years later.

“Tonan, this is the evidence of the Uchiha clan’s betrayal. When all is said and done, it’s your clan. So, I want to hear your opinion.”

“I’ll always stand on the village’s side.”

On that fateful night, Tonan stood on the Hokage Rock, coldly watching the Uchihas’ annihilation.

He spread his hands, being grateful to his clansmen’s gifts.

The next day.

“Lord Hokage, I shed blood for Konoha and became the village’s sword. And this was how you treated the meritorious clan.”

“Tonan, didn’t you agree to it!?”

“I don’t know what you are talking about. The fury of clan extermination is irreconcilable. Today, I will destroy the Sarutobi and Shimura clans to appease my clan members’ souls in heaven.”
