The next few days were less than pleasurable for Kusuri.
His headache was certainly better than it was initially, but even days later it had yet to fully fade. The sole solace he had was that he finally managed to organize the information that had been implanted into his head.
When he did so, it became rather obvious that it was the information that was stored on each of the scrolls, and thus he organized them by scroll to save himself trouble later down the line.
The process was largely indescribable, as was the prior condition of his head.
When all of the info was first placed in his head, it started off scattered and messy, like a library in the middle of a windstorm, but when he focused on it, analyzing and digesting the most basic aspects of its contents, it settled down and settled into his mind as if they had never been anything other than his own memories.
He had that to thank for much of the reduction in his headache.
He suspected the rest of the headache was fatigue from the transfer itself, which explained why the remaining bits slowly disappeared over the rest of that week.
Unfortunately, despite his claims to the contrary, his grandparents declared him still recovering and forced him to rest for another few days. The only caveat was that they allowed him to visit the shop which at the very least did wonders for his boredom. He loved reading, sure, but when it was the only thing he had to do, it got grating fast.
He enjoyed hanging around the tea shop, and since he wasn't allowed to help serve or cook because he was expected to rest, he decided to try to make conversation with the odd patron.
The first day was largely inconsequential, but the second was quite a surprise as he saw a face he recognized.
A rather conspicuous pair walked into the shop: a tall, blond man wearing a jōnin vest and a young blond girl around Kusuri's age.
Now, Kusuri didn't recognize them immediately, it wasn't until he saw the crest on their clothing that he realized they were Inoichi and Ino Yamanaka.
Inoichi approached the counter with a steady pace, guiding his daughter in one hand and holding a large bundle of flowers in the other. When he reached the counter, he let go of Ino's hand to get a better handle on the massive bundle and handed it over.
"Here are the flowers you ordered Toshi," Inoichi announced, "I've got the hydrangeas, wisteria, and chrysanthemums, but not the plum blossoms. My usual supplier went out of business last month."
"I'm sorry to hear that," Toshiyori responded, "Ina loves plum blossoms. I see you've brought a new face with you though! Your daughter I presume?"
"You would presume correctly," he said, reaching down to ruffle Ino's hair a bit, "Say hello Ino."
"Hello," Ino said, somewhat reluctantly.
"She'll be enrolling in the academy next year. Figured she was old enough to join me !" Inoichi exclaimed.
"Our grandson will be as well! His name is Kusuri. He's actually sitting right over there if you want to say hello."
Toshiyori pointed to a small table nestled into the corner where Kusuri was reading a book that Inoichi couldn't see the title of.
Inoichi chuckled a bit before nudging Ino and saying, "Why don't you go say hello to your future classmate?"
Reluctantly Ino obliged, making her way over to the table. At first, she was about to say hello, but then she saw the book Kusuri was reading and pivoted to ask a question instead.
"What's... alguhbra?" Ino asked curiously.
"Algebra. And it's, uh, Math?" Kusuri responded, closing his book and hoping that was a good enough answer.
It apparently was as Ino didn't continue that line of questioning.
"My name is Ino. My dad told me to say hello. Hello."
"Hi?" Kusuri responded, somewhat caught off guard by her tone.
Ino then turned around and walked back to her father, who couldn't help but laugh at the results, with Toshiyori joining in not a moment after.
"I can't say that was outside my expectations, but your boy's reaction sure was. I've never seen a kid make such a confused look before," Inoichi chuckled, "Actually, now that I think about it, how haven't I met him before? And who are his parents? I don't remember you two having kids."
"To answer your questions in order," Toshiyori began, "He usually stays home on Sundays and we don't fully know. We took him in not long after the fox attacked."
Nothing Kusuri's grandfather said had technically been a lie, but he still kinda felt bad about deceiving Inoichi.
"Before you go, would you like to take some dango for the road? We just made a fresh batch!"
"Can't say no to free food! If I did I think it'd give Chōza a heart attack."
Toshiyori handed the pair two dangos, one for Inoichi and one for Ino.
"Say thank you Ino."
"Thank you."
Then, without another word, they were off to return home.
Long after they were at the door, Inoichi talked to his daughter about Kusuri, when he learned a startling fact.
"He was reading a book about what?!"
----------
Two days later, Kusuri's grandparents finally removed his restrictions.
Over the past few days, he had concluded what he wanted to do with his last few days before the Academy.
He was going to start deciphering the scrolls.
He had no idea of their actual contents, as roughly two out of every three words were ones he didn't understand, but he thought that it could potentially be useful in finding ways to utilize his kekkei genkai.
Among his limited options, he suspected his best bet was just to search the library. The problem was that he suspected most of the information to be chakra and/or ninja related, meaning he likely wouldn't be able to access much of it as someone who wasn't even an academy student yet.
Thankfully as he would be enrolling soon enough, he hoped he could gain access to the necessary resources then.
Until then, he would be making many, many trips to the library.
----------
Deciphering the scrolls was a slow process, a fact Kusuri had become well acquainted with over the last few months.
Since, as he suspected, he wasn't allowed to access many of the books that he might've found useful, he had to make do with working around many of the subjects, forced to fill in the holes with context clues and dreams.
Even with such a handicap, he learned quite a bit. Most of it was advanced medical knowledge and other scientific concepts. Each of the concepts was being used to describe various kinds of advanced chakra theory as well as theory about many branches of jutsu such as sealing, but no matter how much he deciphered, without the core information it was gibberish.
It aggravated him to no end.
Despite that, he still kept on studying, his fascination overtaking him time and time again.
It wasn't until he was days before enrollment that he came upon his most important discovery.
The purpose of the scrolls.
Since he had first acquired the information in the scrolls, he suspected they were some kind of inheritance, and to an extent, he was correct.
He had expected to find descriptions of jutsu and technique, and, due to his lack of knowledge, he thought he had, at least at first.
It wasn't until he dug the deepest into the scrolls that he realized what they were cataloging.
It wasn't secret clan techniques or instructions on the use of his kekkei genkai.
It was the single largest repository of research results he had ever seen.
It held the results of decades upon decades of study from countless people, possibly more than twenty on the upper end, and combined it into a mostly complete look at the ins and outs of the entire concept of chakra.
Unfortunately, even without being able to understand much of it he could tell it wasn't complete.
Many of the experiments and inquiries had never been finished, or at the very least weren't completed on the scroll.
Though, if anything, that just made Kusuri even more excited for the years ahead.
With the help of the scrolls, modern science, and a shit ton of free time, he was going to jailbreak a power system.
Eventually.
In like ten years, maybe.
Or twenty.
Probably twenty.
