This story contains eventual yuri, with a bit of an age difference. The main focus of this story is not on the romance and it will be a slow burn with that other girl.
"So, let me get this straight, you want me to reincarnate into the Naruto world to ruin the life of another reincarnate because your brother pissed you off and you don't want him to have nice things?" The very confused woman asked.
"Yeah pretty much." A white sphere of pure energy responds.
"Fuck it, sure. So what can you tell me about this reincarnate?" The woman has been dead for a few hours now so she was kinda missing being able to breathe.
"Well he has seen Naruto, and he has the abilities of the Gamer." When the being of energy said this, the woman frowned.
"Oh yeah, meta knowledge and gamer abilities this will be so easy..." She sarcasticly responds.
"You'll get two wishes you know." The energy being tried to make her situation seem easier but the gamer ability is just hacks.
"Look, there is a lot of hacks abilities better than the gamer system but I have a feeling you'll say no to them." The woman says dryly.
"Try me." The energy being said.
"Okay... Plot Manipulation-"
Before she could even list another ability the being said: "no, none of the reality breaking things."
The woman sighed. "Come on man that's like half the abilities I know, okay uh, what type of things can I ask for?"
The energy being thought for a second, thinking of a list of potential abilities. "Well, the abilities must function as a part of chakra, but you can change some parts of it, like how it flows and forms and stuff."
The woman looked off into the vast void of emptiness away from the energy being and asked a question. "Can I make mine function like cursed energy?" She was a fan of Jujutsu Kaisen though there are several abilities she would want from other media, the problem is all the ones she can think of off the top of her head are reality breaking.
"Sure, though you'd need an innate technique. Any preferences?"
The woman's mind went to limitless almost instantly before realizing this cursed energy wish is kind of a loophole to gain another wish, by having her chakra function differently and being able to have a unique ability on top of that while still having another wish.
She thought about it and wondered if she could just wish for her own gamer system, thinking she'll ask that later, for now she needed an innate technique.
At first, limitless seemed like a good option, but there's no guarantee she'll be born with the six eyes, and she could just waste her other wish on that but there had to be more practical wishes.
"Time Manipulation." She eventually said. Limitless itself is just Spatial Manipulation so this shouldn't be too much of a problem.
"Alright, we'll give it the name Dialation. Now what's your second wish?"
Her response was immediate. "Can I also have the gamer ability?" Unfortunately for her however...
"No, you can not, having two gamers in one place is always a bad idea." The woman sighed, her potential easy option out. Then she got to thinking, what makes games so hard? Usually bosses are hard until you remember their attack patterns but she's not a robot so that's not a problem.
The sense of precog maybe. Gamers tend to have something that can detect other people and incoming attacks to some extent from the stories she's read. The best way to get around that would be to attack so fast the gamer doesn't even have the time to register them.
But Time Manipulation, or Dialation, covers that... Something to boost her stats maybe? She could probably handle that too with the cursed energy function and being able to make a binding vow.
A win condition or trump card then? A potential domain expansion kinda covers that too...
Damage output then. She may be fast but if she's not able to harm her target then what's the point? Cursed Energy should solve that though... She's got it.
