‘It hurts.’

  ‘Why do I have to deal with these things again?’

  ‘Can’t I just simply ignore them all?’

  ‘Do any of these people matter to me? Why must I suffer for them?’

  ‘I hate feeling pain.’

  The thoughts weren't his own, not entirely.

  They were the bitter echoes in the back of his mind. It was the voice of the parasite, the nascent consciousness of the Zero-Tails, now inextricably linked to his own. It fed on his exhaustion, his pain, his despair, and reflected his own darkest, most selfish impulses back at him.

  It was a mirror that showed him his most morbid feelings.

  He lay in the stark white bed of the Konoha Hospital's secure ward, the rhythmic beep of the monitor steadily getting on his nerves.

  The battle was over, but the war wasn’t. There were still a lot of things to deal with, yet here he was, struggling.

  Every twitch of a muscle sent a jolt of pain through his system. His body, pushed so far beyond its limits, was barely holding on. The Shikotsumyaku had began acting up, now far more potent than before, seemingly to mock his attempt to cure it with the artificial tailed-beast project.

  Kasumi sat beside him, her cool hand resting on his own.

  She had not left his side.

  He could feel the worry radiating from her, the desperation in her gaze. He tried to speak, to reassure her, but his body was far beyond any condition to do so.

  "Ryuu?"

  Kasumi’s voice was soft, cutting through the insistent noise of the monitoring machine.

  "The medics are on their way. Tsunade-sama wants to see you."

  He forced his eyes open, the sterile white of the room almost blinding.

  "Tsu… na… de…?"

  He rasped, just barely.

  Before Kasumi could answer, the door slid open. Hiruzen entered, his expression somber, followed by a woman Ryuu recognized instantly. Blonde hair, a distinctive violet diamond on her forehead, and eyes that held a lifetime of loss and an unyielding, formidable strength.

  Tsunade of the Sannin, the world’s greatest medical-nin. It seemed like the attack had prompted her to quickly return to the village, which wasn’t strange.

  She approached his bed with a sharp, appraising gaze. Her hands began to glow with a gentle, green chakra.

  "Don't fight it, kid," she said, her voice a low, husky command. "I need a clear reading."

  The green chakra flowed through Ryuu’s battered system. He felt it slowly examining every part of his body, thoroughly gathering the intel needed but also healing him to an extent.

  Tsunade’s brow furrowed, her professional calm deepening into a look of intense, almost grim, concentration. Her hands moved from his chest to his limbs, the green glow following her path. Ryuu saw her jaw tighten, her eyes flickered with something he couldn't quite decipher. It wasn't surprise at the sheer volume of his chakra but something else.

  Something far more troubling.

  She withdrew her hands, the green light fading. The silence in the room stretched, heavy and suffocating. Kasumi’s grip on his hand tightened, her knuckles white. Hiruzen leaned forward, his pipe held forgotten in his hand.

  “Well,” Tsunade said finally, her voice devoid of its earlier brusqueness, now carrying the somber weight of a grim verdict, “the good news is you’re not going to die. At least, not from this.”

  She looked directly into Ryuu’s eyes, and for the first time, he felt truly seen.

  “The bad news,” she continued, “is that your chakra network is a catastrophe. It’s been pushed, torn, and forcibly expanded by a power it was never meant to contain. Think of it like trying to run a river through a garden hose. The hose didn't just leak, it shredded. The pathways are frayed, the coils are unstable. If you were to attempt a jutsu of C-rank or higher right now, you would risk a complete blowout. You’d be lucky to be crippled for life.”

  Kasumi let out a choked gasp.

  “But that’s not the worst part,” Tsunade said, her gaze unyielding. “The pathways can be repaired, slowly, painstakingly. The real problem is…”

  She placed a single, glowing finger on Ryuu’s sternum. He felt a sharp, icy ache flare from the point of contact.

  “The Shikotsumyaku. I’ve read Hiruko’s and your files, the Kaguya scroll you recovered… it’s a self-devouring illness. Your… ‘symbiote’… hasn’t cured it. It has given it an infinite meal. The artificial beast’s chakra… your Kekkei Genkai is feeding on it, accelerating the cellular decay at an alarming rate. The actions you took in this battle have worsened the ticking time-bomb in your DNA.”

  This book was originally published on Royal Road. Check it out there for the real experience.

  “You mean…” Kasumi’s voice was a terrified whisper. “The illness… it’s started?”

  “Started?”

  Tsunade scoffed, a humorless, bitter sound.

  “Kid, it’s in a full-blown rampage. The only reason you’re not a pile of dust right now is because your other half, your Yuki heritage, is fighting it. Your body is a battlefield. Your Ice Release is instinctively trying to create stasis, to slow the decay, while your Bone Pulse is trying to grow, to consume, to overcome. This balance is the only thing keeping you alive.”

  Ryuu stared at the ceiling, the sterile white panels blurring into a meaningless void. It was worse than he thought. He had gambled and won the battle, only to accelerate his own condition further.

  “Is there… a cure?”

  Hiruzen asked, his voice heavy with the weight of an old man who had seen too many prodigies burn out.

  “There is no cure for what you are, kid,”

  Tsunade stated flatly. She looked back at Ryuu, a fierce, almost angry determination igniting in her eyes.

  “But we’re not going to let it kill you.”

  She leaned over him, her presence filling the room with an indomitable will.

  “We are going to fight it. You and me. Starting now. We are going to place you in a medically induced coma. Your chakra network needs to be shut down, completely. I’m going to use my own skills, combined with the data you and Hiruko gathered, to develop a series of seals and cellular regeneration techniques to not just repair your pathways, but to rebuild them. To reinforce them.”

  Her gaze sharpened.

  “And while you’re under, my team will analyze every strand of Kimimaro’s DNA, every scrap of information in that Kaguya scroll. We will find a way to truly cure it, not this… uncontrolled feeding frenzy. It’s going to be the most complex medical procedure in shinobi history.”

  She looked from Ryuu to Kasumi, then back again.

  “It will be painful. It will be dangerous. And when you wake up… you will have to re-adjust to your chakra, and possibly even have learn everything from the beginning.”

  Ryuu looked into the eyes of the Legendary Sannin. He saw no pity. He saw a challenge. He saw a glimmer, not of hope, but of a path. A brutal, agonizing path, but a path nonetheless.

  He closed his eyes, a single, clear thought cutting through the pain and doubt.

  “Plea… se… pro.. ceed.”

  Tsunade didn't flinch at his ragged whisper. She met his gaze, her own filled with a hard, unwavering resolve that was, in its own way, reassuring.

  “Good,” she stated simply. “Hiruzen-sama, get Kasumi-san out of here. Shizune!”

  Shizune appeared instantly at the door, a medical trolley already laden with supplies. Hiruzen gently placed a hand on Kasumi’s shoulder.

  “Come, Kasumi-san. There is nothing more we can do here. We must trust in Tsunade’s skill.”

  Kasumi looked from her son’s pale face to Tsunade’s, her eyes pleading.

  “Please…”

  “I don’t make promises I can’t keep,” Tsunade said, not looking at her, her focus already entirely on Ryuu.

  “I said I will fight for him. Now go. This room is about to become the most secure operating theater in the Land of Fire, and you are not on the approved personnel list.”

  Kasumi hesitated for a fraction of a second longer, then leaned down and pressed a kiss to Ryuu’s forehead, her lips trembling.

  “I will be waiting.”

  She whispered. Then, she allowed Hiruzen to guide her from the room.

  The door sealed with a heavy, definitive thud.

  “Shizune, prep the chakra stasis seals and the nutrient drip. I want his biological functions fully supported externally within the hour,” Tsunade commanded, already preparing a complex array of needles.

  “This is going to be a long procedure.”

  Naruto stood next to the other Jinchuriki, his mother watching over him with a strained expression. A few days had already passed since Pain’s attack, which had resulted in a major devastation of the hidden leaf village.

  Minato had returned a few hours after the attack had concluded, injured and tired from his own battle. Kakashi and Itachi glanced at the destroyed village with solemn expressions. The hokage summit had ended in an uncertain manner, since Minato had to rush back to Konohas as soon as their battle ended.

  Obito had kept them back long enough sadly.

  “Ramen?”

  Naruto offered, holding out a half-eaten bowl. It was his fourth since they had been cleared from the wreckage. Utakata simply shook his head, while Fu gave him a weak smile, shaking her head. Gaara didn't even acknowledge the offer.

  The four Jinchuriki sat on a pile of rubble that was quickly being cleaned for reconstruction. The air was filled with the sounds of hammering, the shouts of jonin-led construction crews, and the low, ever-present murmur of a village grieving.

  Naruto had wanted to help, to use his clones to clear debris, but his father had been firm.

  “Stay with the others, Naruto. Right now, your safety is paramount.”

  He didn't like it. He felt like he was being treated like a child, even though he knew he had played a part in saving the village. He had seen Ryuu fight, seen what a real Jinchuriki could do.

  And he had felt… inadequate.

  "He's gonna be okay, right?"

  He asked, looking towards the towering edifice of the Konoha hospital. It was one of the few buildings in the central district that had remained mostly intact, a testament to its sturdy construction.

  "Tsunade is with him," Utakata said, his voice a low rumble. "If anyone can save him, it is her."

  He didn't sound particularly hopeful, just factual.

  "He's strong," Fu added, her usual bubbly energy subdued. "He's the sturdiest person I've ever met."

  Gaara said nothing, but his gaze, too, was fixed on the hospital.

  The arrival of Minato was not a surprise, but the gravity of his expression was. He looked at the four children, his eyes lingering on each of them in turn.

  "We have received word from the other villages. Akatsuki has not been idle."

  He paused, letting the weight of his words settle. "Kumo and Iwa have both reported attacks on their village. They were repelled, but not without significant losses. Akatsuki's primary objective is now clear to all."

  He looked at Utakata, at Fu, at Gaara, and finally, at his own son.

  "Konoha is now the safest place for you. We will be forming a joint Jinchuriki protection and training unit. Your respective villages have agreed, for now, to have you remain under our protection."

  He didn't mention the political wrangling, the demands for concessions, the thinly veiled threats. That was his burden to bear.

  "We need you to become stronger, not just as individuals, but as a team," he continued, his voice firm with a Kage’s resolve. “We need you to master your abilities, to understand your power. And for that, you will have the best instructors Konoha can provide.”

  A new figure appeared beside him, a tall, imposing figure with wild white hair and a mischievous glint in his eyes that seemed strangely at odds with the somber mood.

  "That," Jiraiya of the Sannin declared, a wide, confident grin spreading across his face, "is where I come in."

  He looked at the four Jinchuriki, a gleam of something old and powerful in his eyes. Nagato’s attack on Konoha had weight heavily on him, but he had no choice but to bite the bullet for now, since Minato already had plans to deal with him.

  He wanted to meet his disciple again, to understand the truth, but he was forced by his own choices.

  "Alright, brats," he said, his voice booming with a confidence that seemed to push back against the despair, "school's in session."
