The nurse rolled Zurui into the hospital. They'd received word from Konohagakure a few days ago, so they were expecting his arrival and were, therefore, well prepared for it. Because of this, the nurse was able to wheelchair him right to the recovery wing where there read a room waiting for him. Seeing that she wasn't stopping to ask anyone if there were rooms available, Zurui reasoned that there was one already picked out for him, which meant he would have no chance at being transferred to the coma wing. Given his findings in Konoha, he very much wanted to be in that wing.
"I'm sorry, but if it's not too much trouble, could I spend my time in the coma wing?" He asked the nurse. She stopped the wheelchair and pursed her lips. It wasn't exactly protocol, but there wasn't anything against it.
Seeing that she needed more convincing, Zurui chimed in again. "I'm not fond of being around people, so if I must be, I'd rather them be asleep the entire time." The nurse nodded her approval. The room picked out for him was unoccupied at the moment, but given that they were expecting to have him for two or more weeks, or was very likely that he'd get a roommate at some point. If he'd be happier with a sleeper, then she would definitely love to oblige.
"Okay, we do have an open room there. If anyone gets admitted, away least they won't be able to disturb you." She replied with a kind smile. Zurui returned the expression and sat silently whilst she rolled him to the coma wing. It sounded like he wouldn't have anyone in his room to start off with, so he'd have to sneak around to see if any other of his kind were here. He probably should've done the same in Konoha's hospital, but the pain in his torso was way too uncomfortable for him to go sneaking around. He still should have. Comfort can go to hell when it comes to his destiny. At least he felt a bit better now, so it would be easier.
The two arrived at the empty room and Zurui was helped onto the bed before the nurse went to the reception desk so as to make official the Jounin's current living arrangement. Seeing no need to rush things, Zurui remained in bed and rested for many hours, until the sun had fallen and the night shift was well under way. There were less staff around at that time, which would give him a lot more breathing room to go on about his personal mission.
The Jounin activated the sensing technique to locate everyone in the building. He paid special attention to those in his wing, as well as any that might coincidentally catch sight of anything in the coma wing. He needed to take no chances, for while he could do it, it would be awkward explaining what he was doing in a coma patient's room if he were caught. Best to avoid that situation altogether.
When he felt confident in the predictability of the hospital staff's patrolling paths, he waited for a moment when nobody would be looking for a while and made his move. With the positions and directions of everyone within the building at the forefront of his mind, Zurui began to enter the other rooms, making the sound of his movements with Silent Killing while making his appearance by staying only in the areas where nobody was looking. This made for a lot of stop and go, but he maneuvered through the area brilliantly due to his strategic mind.
After making it through the whole ward, Zurui let out a muffled, exacerbated sigh. He'd seen not a single person with white hair. It was entirely possible that there was an Otsutsuki here with a different hair color, though. After all, Zurui himself, though born with hair white as snow, often masks his appearance, which almost always involves changing the color from white. He still had faith, in the back of his mind, that he might find one of his own in this place, but what he'd have to do to find this individual would be troublesome. He needed to make absolutely sure, beyond the shadow of a doubt, that nobody saw him. For the only wayi to know for sure without spending two days trying the Six Paths ritual on all of these people, was to activate his own Rinnegan. After going through so much work to keep his Kekkei Genkai secret throughout his life, he absolutely did not want it to go to waste now, for this.
Zurui closed his eyes. When they next opened, they were changed. They were violent and bore now two rings, a sign of the power he'd taken back in Konoha. Focusing on both his vision and his sensory ability, Zurui moved quickly through the halls, peeking in every room and entering a few to ensure that he caught sight of everyone in this wing. He was nearing the end, preparing himself for the possibility that his target was not here, when he saw it. An aura of violet, a color akin only to his Doujutsu, emanating from the body of a young...person? He couldn't tell the gender, but it mattered not to him. The Jounin slipped into the room and hid in the corner, waiting for a nurse to pass by before he proceeded.
Much like the last time, several days ago, Zurui placed his hand on Eden's forehead. His eyes looked at theirs and, after much effort and some time, Zurui managed to draw out their Path. It was somewhat fortunate, he thought, that neither of those two had activated their abilities, Aryn and Eden. While they never got a taste of that awesome power, they also wouldn't know the loss that befell them, even now. A few moments later and Eden's eyes snapped open. Their Rinnegan was active and Zurui watched as the ring in their eye faded away not long before the color drained from them. Their eyes returned to their usual red color and then closed once more. They never woke, never felt a thing, as the Jounin stole from them the power granted them at birth. He looked at their helpless body with his newly three-ringed Rinnegan, giving thought to something he'd dismissed in Konoha.
Would it not be a gift to offer eternal use to a corporeal body destined for naught but death and rot? It was a mercy, to put down someone trapped in prolonged suffering. The gift, then, was to allow a person to continue existing in this world when they can no longer do so themselves. Eden may die now, or in a few weeks, and most will have never heard of them. If, however, Zurui bestows upon this body the Rinnegan's unique receivers and allows them to remain in this world as a Path, a puppet corpse under his control, then many will know of Eden. Many will fear and admire them. How kind a gift was that?
It probably wasn't kind, but he wanted to look at it like that. Zurui removed the sheet and blanket from Eden's body and then slipped a hand under their clothing. Black metal penetrated their flesh from his, and eventually their torso and upper arms and legs were sparsely covered in black receivers arranged like many piercings. He gave the same piercings to their ears, like studs lining the outer cartilage, and left the room when the next opportunity came so that none would see him return to his own assigned bed.
For the next few hours, Zurui kept his sensing active, waiting for the next nurse to visit Eden's room. When the nurse entered, Eden suddenly opened their eyes. The nurse shouted for help and hospital staff swarmed the room. It was a miracle of medicine, they thought, such that only some questioned the change in eye color from red to ringed violet, and even they dismissed. Nobody even noticed the piercings in their ears and none ever saw the piercings lining Eden's body. The nurses simply ran the requisite tests, which were difficult for Zurui to take. Eden was dead, now, and it was only because of their recent passing that the Jounin was able to use his chakra to fake all of the signs of not just life, but healthy life.
Nevertheless, Eden passed and, skillfully hiding the blood on their sheets left from when Zurui inserted his receivers, changed from the hospital gown and into the clothes they were admitted in. Eden then went on to venture out of the hospital, sharing vision with Zurui, who himself was stuck in the hospital until his wounds fully recovered. Eden never went too far away and would sometimes stop by the hospital, so as to always be within range should anything unexpected happen.
Nearly a week and a half later, Zurui checked out of the hospital, confident that he'd recovered enough to function near full capacity again. During this time, Zurui paid similar visits to others in the coma ward, injecting them with receivers in such a way that they were killed and the receivers themselves were unnoticeable through clothing. One by one, five others suddenly woke from their coma, passed the tests, and were released from the hospital. Time passed between them in such a way as to not draw too much attention, though someone was bound to notice six people walking when for years it was commonplace that all coma patients died. Zurui just hoped nobody in a position to cause him trouble would notice.
Like Eden, the others lingered around the general area of the hospital and wore coverings over their eyes, like sunglasses, to mask the reflection of Zurui's Rinnegan. When finally the Jounin walked out of the hospital, he had Eden Syn, Amaya Taira, Nami Hozuki, Kaido Kazama, Kazumi Yuki, and Magnus Kaguya. It would be a new squad in Kiri, to everyone else's eyes, led by Zurui. In reality, that wasn't quite true.
