"Ah, just take my life!"
I am a man who left his name behind, hoping to be forgotten forever...
I was born as a weeb on Earth, with siblings. To put it briefly, I am the black sheep of the family, and I can confidently say I have the worst luck imaginable.
Either way, after living a miserable life filled with turmoil and misery, I died. For once, I was glad it was all over. Maybe I'll be reborn next time as someone better.
...
The sound of a child crying could be heard from a room in a building.
A child was just born into this lovely world.
'Apparently, that was me. And holy crap, it seems like a ritual is going on here.'
'Damn, I'm already feeling dizzy...'
...
Three years later, I'm in a house, eating as usual with my siblings, in the village of the Sand, as usual. And, as usual... in Gaara's body.
'Gaara's body? Seriously? Is my luck really this bad?
'I thought about my past life and then this life... as Gaara?'
'There was no other character in the famous Naruto universe like any of the Uchiha, and of course, I'm an Uchiha fan. Even the Hyuga, Senju, or Uzumaki clan would have been better to be reborn into.'
'Of course, I'm bitter about this. Gaara's potential basically ended, and he was only relevant because he had Shukaku. Otherwise, he wasn't the worst, but even less important characters had more screen time.'
'Either way, ever since I got into this world, things haven't gone as planned. I tried stopping the hostility toward me and even showed affection, acting like a normal child. But it all led to the same result.'
'At the very least, I thought the storyline had to be followed. But thinking about it again, why was I reborn here? I thought being reborn would give me some kind of cheat system like in the novels, but no, it didn't.'
'Looking at it from another angle, maybe it did give me freedom in another way. I can't necessarily change the people around me right now, but I can change myself. There may not be a system, but who cares.'
"So, I've decided to... Um? Actually, I haven't decided on anything yet, so let's just say I've decided to get enough screen time."
"Huh? What are you talking about, Gaara?" Temari asked me.
"Uh, nothing. Just a bad habit of talking to myself."
"..."
'To be sure, there are two essential things I need to master to survive. First is chakra control, but at this age, it seems nearly impossible—I don't even know what chakra is yet.'
'Second is taijutsu. I can't exactly practice it, but I feel more drawn to that direction. I need to overcome Gaara's weaknesses of relying heavily on Shukaku and his low mental fortitude.'
'Third should be some ninjutsu, but that doesn't matter for now. Until I learn to sense chakra and control it, any chakra-related skills should be put on hold.'
'I wouldn't want to be controlled by the storyline, so my training should start tomorrow. But who should I approach to train me?'
