Life Training
Mirio forgave her a day after their conversation, but before that he tried to convince her that nothing would happen to him, and of course, she didn't budge. There were signs of them starting to fight again, and she really wasn't in the mood, so she convinced him to agree to disagree. They won't speak about it nor try to persuade each other...at least not in a direct way. She is pretty sure she can change his opinion little by little without him noticing, and if it doesn't work, she can always use her sharingan to take away his silly hero worship mindset. That would make her feel like shit, but 'desperate times call for desperate measures'.
...
Still, if he was going to forgive her so soon, why did he told her he hated her? That hurt.
...
Awesome. She is becoming a child.
Chieko had already noticed it. Sometimes she can't control her emotions as good as she should. Until now she had been putting the blame on the trauma of her past life—Shisui's death, t̶h̶e̶ ̶p̶e̶r̶s̶o̶n̶.̶.̶.̶, the visions of her Mangekyo Sharingan almost got her crazy, she realizing she had failed her brother, and her suicide—, but maybe it's also this body...she hopes part of it is her body because that will fix itself.
Anyhow, she will address her problems in order of importance, and right now the most important thorn on her side is her chakra. She had been thinking of it for a while now, but the circumstances weren't good nor desperate enough to address it. Now she is almost 4 years old and it should be safe to start her training.
So.
She knew since before she was born that her chakra was unbalanced, her spiritual energy surpassed her physical energy many times over, but she thought it was because she was 'dead'—obviously she wasn't, but that was her theory at the time—. Although that disbalance isn't new—everyone has a little difference in physical and spiritual energy—, hers is huge and it could be dangerous, but she isn't a medic-nin, so she can't be sure. The good thing is that the gap between her energies gives her an opportunity to increase her chakra pool like nothing she had before—her spiritual energy will just continue increasing while she grows and learns, and training will increase her physical energy—, and sooner or later she will be able to use her Mangekyo Sharingan at full potential. Hopefully, her eyes won't be as useless as they were in her past life.
First things first. Stop repressing her chakra, observe it's behavior, make sure her tenketsu points are functioning correctly, and see what's the difference with her previous chakra system.
It took her a whole week and a half to througly check everything. It would have taken more, but she practically doesn't have anything to do besides eat and sleep, although her parents were begun to get worried when they didn't see her reading anything or asking about the world. The liberation of her repressed chakra hurted a little—it was a good thing her father wasn't there—, and the disbalance between her energies left her dizzy, but the human body is a perfect machine, and it naturally stabilized the two energies in 4 horrible days—her parents thought she was sick—. Which only means that the paranoia that made her hide her chakra almost killed her. Awesome.
Chieko was lucky...for once...Although now that she thinks about it, this life has been pretty good. She couldn't have wished for a better family.
...
Back to topic. Her chakra system is bigger and feels different, but each one of the 361 tenketsu points works properly, so now she will try to manipulate her chakra with the easiest exercise you can do: the leaf practice. Well, she doesn't have a leaf, but she can use any other thing.
She makes sure the nanny is distracted in the kitchen, and then locks herself in the bathroom.
The exercise is fairly simple, 'control your chakra with enough precision that the leaf/object sticks to your forehead/hand/etc'. She feels the energy inside her, and notices how it moves through her body, then she accumulates a little of it on her hand and sticks the toothbrush on it...and...perfect.
Chieko practices a little, sticking the toothbrush to wherever part of her body she wants. She fails sometimes, because her chakra is bigger and more difficult to control, but when the nanny calls her, she gets out of it with a grin on her face.
That same day she starts doing basic physical exercises. She would want to start with Academy katas, but she doesn't want to strain her little body and end damaging it permanently.
Chieko decides to only train when her father isn't there-she doesn't know exactly how his quirk works, so she doesn't want to risk him noticing her 'weird' training...although it is bound to happen at some time, better later than sooner, at least until she has an excuse good enough-, and divides the day with the nanny in chakra training, from 2-3 hours, and physical training, 30 minutes.
Part two of her training starts two months later and has to do with controlling her chakra outside her body. She doesn't want to risk to try any jutsu until she is sure she can balance and control her chakra when its outside her body—she doesn't want to deplete all of it by accident—.
Again, the only ones on the house are the nanny and her, and she takes full advantage of that. This time, she faked to go to sleep, and waited until the teenager left her room.
Now, the ideal thing to do would be tree walking, but even if she does it on the walls, if she makes a mistake she could break the wall, and that would be horrible. Therefore, she will try other excersice a little more difficult than tree walking, but less difficult than water walking.
It's a basic modified training for iryo-ninjutsu. Even though she had a good chakra control in her past life, she didn't have the ability to control ying/yang release, thus she never learned iryo-ninjutsu, but she knows the basics. Medical ninjutsu basics are about exteriorising your chakra until its visible, and then only using the ying/yang release to cure. She can do the first part.
Chieko exteriorises her chakra through her palms until a faint blue light is visible...
Now, she needs to make it a little physical, but without using chakra nature, like if she were doing a jutsu...she needs to materialize the enegy, and the best way to see if she's doing it right is with an object.
...she carries the teddy bear on her palms and concentrates on it...the doll starts to float 1 centimeter above her hands just as expected and then...it bursts. When she hears steps going up the stairs, Chieko quickly hides the rests of the bear under her pillow, and pretends to sleep.
"Everything alright...?" the girl sounds confused and a little worried, but after taking a good look to the room, she dismisses her thoughts and goes back down.
Okay. Good news? It isn't that difficult to balance the energies on her chakra. Bad news? Her chakra control still needs a lot of work. However, all of that will wait until she takes a real nap, she exhausted a lot of her chakra.
"What?"
"It's just so you can make friends. Okay? It will be fun" her mother is trying to convince her while her father analyzes her, and she would usually do whatever they tell her to do, but this time...
"I don't need friends, I don't need to, and I don't want to go" she feels that frustratingly childish pout start to form on her face.
"Everyone needs friends, that's how we humans work..."
"I mean I don't need more friends, I already have Miio! Besides, I won't learn anything I don't already know..." the voice of her father interrupts her.
"Would you prefer if we try to move you directly to first grade?" his curiosity is real, but the simple thought of being treated like a genius by strangers makes her want to throw up. Her family do treat her like the 'smart child' she is, but they do it with love. She remembers the responsibilities, pressure and stress the Clan placed on Itachi and Shisui. She recalls the heavy expectations of Konoha towards its geniuses, and she doesn't want any of it.
Better to suffer because of boredom than because of stress and anxiety. She has more than enough of that.
"I will go..." the answer makes her parents look at her surprised, but they quickly change their expressions to more happy ones, assuring her that she will have fun.
She hopes so.
She's not having fun. Not one bit. It may be because they are real children and she's not, or because she didn't want to be there since the start, but the truth is she is hating every minute of this thing called 'Kindergarten'.
The kids are loud, hyperactive, and fight easily. There are some kids who look kind of interesting, but they are the type she prefers to observe from far far away. Chieko already said it, she doesn't need more friends, there's enough people in her life to worry about.
Some children try to talk to her, and the adults taking care of them try to encourage her to socialize, but she maintains her position, and keeps to herself throughout the day.
When the time to go home arrives, her grandfather is the one to come and get her. They walk home holding hands.
"How was it?" he asks like if he didn't know, but if her parents haven't told him she didn't want to go, her feelings should. Daisuke has the same quirk her father has, but his is a little weaker.
"You know how was it. Horrible"
"Did you even try to enjoy it?" and now he's making fun of her...Chieko looks at him with narrowed eyes, and then gives up and tells him what he already knows.
"...not really...But it's not like I can have fun with them anyway! They won't understand what I talk about, and the only theme they know a little about are heroes, they are completely obsessed" Daisike looks at her with a raised eyebrow, and refutes her answer.
"Mirio is 'obsessed' too" please, don't remind her. With a huff, she stops talking, trying to convey her anger. He keeps quiet for a few steps, and then continues.
"So the problem is that you don't have themes in common with your classmates" he always knows how to simplify things to the extreme. "Maybe you could take one of your books and read it to them"
"Right, because they will understand what I read" she deadpans.
"You could read them one of your fantasy books" he looks at her face and seems to see something he doesn't like because he sighs and speaks more seriously. "You already know you are more intelligent than other children, and I understand that makes it difficult for you to socialize with them, but you shouldn't close yourself up...you could treat them like if they were your little siblings and teach them things slowly" she's not closing herself, it's just...people are problematic, and difficult, and...for Kami's sake, why does she even need to interact with those kids?
"Just try it. If you don't like it, we won't insist more. Okay?" she mumbles an 'Okay' towards he laughs at. "Now, does my favorite granddaughter wants an ice cream?"
"I'm your only granddaughter..."
"And you are my favorite, so...?"
"Mom doesn't like it when I eat dessert before lunch"
"Well, what she doesn't know won't harm her. Right?" oh, my...she giggles and gives up. She loves ice cream, and he's correct, what her parents don't know won't harm them.
The next day she takes the 'Percy Jackson and the Lightning Thief' book, and asks the caretakers to let her read it to the group. Chieko isn't very happy about it, but she can take the opportunity to train this body to imitate/change voices.
Although she doesn't let it show on her face, she ends up having fun, and the kids leave the day giving her big smiles and happy waves, telling their parents how awesome is their friend who imitates voices. That makes her a little —just a little bit—happy.
"Y-you are incredible! Is your quirk what let's you do that?" a boy with green hair, and freckles talks to her with shining green eyes. There's another kid behind him that tries to look disinterested, but fails miserably.
"No, I just know how to do it"
"Cool! Could you teach us?" she was going to refuse, but those fucking puppy eyes...my God, why does these walking suns keep appearing in front of her?
"Sure..." the boy left an excited squackle and spoke to the blonde kid.
"Did you hear that Kacchan? She is going to teach us!"
"Wathever" he said, but he got closer when he heard the confirmation.
"I'm Watanabe Chieko. You?"
"I'm Midoriya Izuku!"
"Bakugou Katsuki"
Izuku's voice contrasts terribly with Bakugou's voice. She doesn't even think their personalities match. The green haired boy is a cutie and kind with everyone while she has seen the blonde one being a brat sometimes—yes, she may have watched her classmates. No, she's not stalking them, she's just seeing who is worth her time—. How is it possible for these two to be friends?
It may not be so bad, making friends. It would be a good thing if they were normal civilia-...
"...and we're going to be heroes!"
For fucks sake!
