Finally, the doctor was finally getting it. It was something so trivial, yet it felt like some huge challenge was finally removed from whatever was ahead of the Isaki. He couldn't help but take some pride in that success. With it, too, some sense of calm -- or, more accurately, Karu was finally starting to not panic as much -- came. His mind wasn't as scattered; thoughts were beginning to make a bit of sense as he more focused himself on the goal of recovery. Whatever came next would be a challenge for then. He had more immediate problems before him, one of the most minor being which pronoun was even accurate anymore? Eh, that'd be something for him to worry about later.
He was caught off guard when the doctor lifted him, but he remained silent. Speaking was difficult enough; he couldn't be expected to follow the minor nuances that came with being in one's own body, like shifting around, or making noises to indicate being startled. He was like some large doll that the doctor carried around for whatever reason; given its size, it couldn't even be that heavy either. Perhaps 50 kilos at most; given the likelihood he was a shinobi, the weight was laughably easy for him. The stares weren't the widest of spaces, but had adequate room for Karu's body to be moved without the doctor having to side-step. Moving away from that room and upward revealed more natural lighting. The orange and red were beaming directly onto them; what hair fell in front of Karu's face with each step seemed glowing in the light. Objectively, from what he had seen of the body he was in, it was certainly not unsightly. "...ime s'it?" Karurosu asked lightly with no objections to whatever else the doctor did while moving upward. Without any obvious indication of where north was, he wasn't sure if the day had just begun or was just completed. Was it the say day as the incident or how much time had passed? He bothered not even wondering about where he was; he knew the country, at least, but anything beyond that would be information that meant nothing to him.
He had a room for rehabilitation. Why? Were all the doctors in the village working alone? It was a strange thing, but as to be expected in such a strange place. It was questionable if the Isaki would ever fully understand the ways of Iwa.
The room was large, to say at the least. Several people could train in here consecutively without feeling cramped or in another's way. It seemed pointless for a man to have a rehabilitation center of his own of this size. A couple weeks of unending practice in here would be more than adequate to get to the point of autonomy without assistance. The Isaki couldn't estimate how long it would take to reach a fighting level again, if he ever could.
Finally, abruptly, he was placed into a chair and situated to face the doctor. It was brighter in here, less clinical. He wasn't sure if he cared too much for that aspect; much of his life before was stuck in such a setting that the over-sanitary rooms felt like a second home. Perhaps his true home, given that the mansion was never a home for him.
Now it was time to train, beginning with the most trivial thing. Speech. He was managing to get the most basic sounds out, yeah, but it was not without major difficulty and exhaustion. Chakra wasn't working like he was accustomed to. He didn't have a real body anymore, he couldn't rely on it as he was accustomed to. How, then, could he use it? The only other items he had focused it into was when he used ninjutsu or genjutsu, but even those were done only ages ago. Was it like channeling through a weapon? What weapon would be fitting of a carcass, though? None that he had ever seen; weaponizing a body wasn't something that was common.
The motions were what mattered, not what caused them. His familiarity with chakra came with how it interacted with the body. That's where the difficulty came from. It was like controlling a marionette with strings of chakra. Like some puppeteer with wires that were invisible. Yeah, like a puppeteer. Karurosu imagined the memory of what he had seen this body look like: the small girl with limp muscles, all obvious joints there. He considered the jaw. He knew how it could move; human anatomy was an easy subject to memorize when you're young and its forced upon you. He imagined wires holding those joints that permitted movement. If he could move them as though they were manipulated by wires, perhaps it would be easier.
Several moments passed.
"Thanks..." it was still difficult to speak, but more mobility seemed possible. The doctor wouldn't be able to get a speech out of him, but if he could keep this up, they could begin, at the very least. "Name?" the female's voice came in rising intonation. The voice really was rather annoying. Too kiddish for Karu's tastes.
