It has been 3 years since he arrived in this world. He was eighteen when he arrived and now he was twenty-one. Yes, that is how basic arithmetic works but except he wasn't twenty-one, he was three. It was a difficult predicament but it was something he came to accept after experiencing infanthood all over again, this time fully aware, however.
On a positive side note, this gave a lot of time to ponder, realize and accept things and then eventually move on and get over the loss of his previous life. Getting back the same level of motor control or at least sufficient levels of it took a lot of patience.
It should have ended when he was 18. The death should have been it. But it didn't and now he was here, in Naruto of all places. When you end your own life, you are not supposed to get a chance to live again. Not when you didn't want it or when you yourself ended your first one. He wasn't sure if had the willpower to end his second life. The first one must have drained it all.
It was either a blessing or a curse. A blessing because it gave him a chance to do things differently this time. A new chance, Not everyone gets it, he presumed. Unless all that awaited us after death was to get isekai'd into a fictional world. A curse because maybe he was fated to do repeat things. After all, He was the same person in a different body. The same miserable fate that caused the end of his previous one.
There weren't many people, this time around. His family, this time only consisted of his mother and himself. No father in the picture, it seems. He could deal with that.
His mother, this mother, he had grown fond of her. Or ' kaasan' as he calls her now. At least he could talk in sentences now. Japanese was hard. don't let anyone else tell you otherwise.
His mother had red eyes, red hair. She looked the exact opposite of him. He had black hair and black eyes. Perhaps, He was adopted? She was a kunoichi, that much was evident considering how long he lived with her. Someone she took pity on rather than silting his throat along with his parents. You know? the usual cliche or maybe she adopted him when she went for a casual stroll. He didn't dare ask, not when she was the one keeping him alive. Three-year-olds don't ask that type of questions.
He lived in Kusagakure no Sato, the village hidden in the grass. No Hokage monument here. It was a simple village with a simple life. Peaceful, far away from canon. Living in Kusagakure no Sato had its disadvantage though, he had no way of knowing when in the timeline he was. But he could safely assume it was probably in the generation of naruto and the rookie nine. As for becoming a ninja, there was never even a question about it. He at least needs to be able to protect his mother, if not everyone. No, he wasn't going to be the hero of the story. Saving his loved one and himself is enough. The rest could die in a ditch.
