After traveling through Naruto, he became a non-existent name in the Uchiha clan.
There is no system, no plug-ins, only the memories of the previous life and the home of this life. His father, En Uchiha, was a taciturn chuunin in the police force, and his mother, Shizuo Uchiha, would hold his hand and form seals when teaching him earth escape. There is a maple tree in the yard, which turns red every autumn.
He knows many things. He knows about the Kannabi Bridge, he knows about the Nine-Tails Rebellion, and he knows about the genocide of the Uchiha clan. He did everything he could - spread out his perception network, promote family collaboration, and try to pull more people to safety before tragedy struck.
Then tragedy struck. He missed a step. One step missing every time.
This is a story about "knowing but not being able to do it". About how a person who remembers his previous life learns to face loss in this life. About the fact that he saved some people and watched others slip through his fingers.
Life is not worth it. But fate can be connected.
His name is Uchiha Jin. Embers are what remains after burning.
