Sweat rolled down Kakashi's face as he hastily dropped Naruto off his back and retreated away from the boy. He and the doctors clung as close as they could to the scorching hot wall, watching as one bubbling, hissing, orange tail grew from the shroud of chakra surrounding Naruto. The heat in the lift shaft was unbearable; it made it feel like even the air was on fire.
Kakashi watched Naruto as the boy came to settle in the centre of the lift, his clawed fingers clenched against the rubble, his breath ragged, his eyes focused directly on him. The roaring sound above became even louder and the doors of the lift some 10ft above them began to glow from red, to yellow, to white.
A more animalistic roar sounded right in front of Kakashi. He flicked his eyes down and sprang sideways, just missing the chakra claw which now powered into the hot metal. Naruto turned his blood red eyes to Kakashi and roared again, the loud, feral sound scraping against his ears. He sprang left again as another chakra hand shot out towards him, narrowly missing his torso.
What the hell do I do?! he thought desperately, creating Shadow Clones to try to stall Naruto. It did not perturb the monster as, once again, he aimed directly at Kakashi. He dodged another attack, ending up in a corner of the lift, a direct target for Naruto. He watched in horror as another tail grew from the bubbling mass around his student. We have to knock him out! he thought as he quickly glanced up at the glowing lift doors.
He saw his mistake as soon has he refocused on Naruto. The Kyūbi sprang at him, wrapping both his real and chakra hands around his waist. The pain was unbearable; Kakashi screamed and writhed as his skin burned horribly. He opened his clenched eyes to see the able doctor spring into action, bringing out a kunai and throwing it; watching as it sank into Naruto's arm, making him drop Kakashi.
Naruto roared again, turning on the doctor, but Kakashi grabbed a large piece of metal and slammed it over the boy's head. He crumpled to the ground, out cold as Kakashi fell beside him, succumbing to the unbearable pain around his waist. The roaring sound stopped.
Tsunade had kicked Sasuke. He flew sideways, slamming against the wall at the end of the corridor. Snarling, Sasuke sprang up. "What the hell do you think you are doing?!" Tsunade shouted, her face twisted with rage. "They'll die in the heat down there! If you think that using a showy technique like that would save the day, then you were tragically mistaken. How dare you further risk the lives of the people in that lift shaft?! How dare you use a technique in my hospital without my permission?! How da- ?!" She stopped mid-sentence. "Get a Water Release user here, quickly!" she shouted down the corridor. The medical ninja blocking the doorway approached.
"I'm a Water Release user," he said, standing to attention.
"Cool it!" she said, pointing at the still-glowing door. "Supercool it now!"
The doctor ran forwards, making Hand Signs as he did so. Positioning himself directly at the door, he shouted "Suiton: Suiryūdan no jutsu!" A great dragon of water appeared, its translucent body rippling, before he sent it directly at the door. Steam billowed down the corridor, blinding the occupants, but instantly cooling the room. Tsunade ran forwards and touched to door; it was cold.
She nodded at the doctor who stood back, vanishing into the thick, steamy mist before she readied an attack. Building up her chakra, she punched the dented door. It shattered instantly. Sasuke appeared along with the doctor and the three peered down into the black lift shaft. What they saw was absolute chaos.
Naruto was sprawled in the centre of the crumpled lift, his skin torn, his breathing ragged. Kakashi was no better; a great burn drew a ring around his waist, and he was barely conscious. One of the doctors who had been tending to the two looked up and grinned as he saw the three heads in the doorway. The other doctor, leaning against the lift shaft, his leg trapped, called out quietly.
"We are all alive… some more than others…" he gestured to the two in the middle of the space. "Please get us out," he finished, his voice wavering.
Tsunade, Sasuke and the doctor jumped down into the shaft. Rubble shifted under their feet as they landed. Sasuke began to extract the trapped doctor while Tsunade and the two medical ninjas tended to the others. A blue dome of light glowed under Tsunade's hands as she healed the torn skin on Naruto's body.
"Explain what happened thoroughly later," she said curtly to the two doctors who had been trapped. They both nodded solemnly. Two more domes appeared over Kakashi's middle as the doctors began work.
For those who asked (and, of course, for those who are curious), meningitis is a disease caused by a bacteria or virus. It is contagious and can most easily be spread this way both through animals (rarely) and people; however it can also occur as a complication from injury or illness. It is most common in children, though it is also seen in teenagers, much Like Naruto here. The viral meningitis is a lot less serious and often doesn't need hospital treatment. The bacterial kind, however, is extremely dangerous and can kill in a matter of hours. As most adults over 25 have immunity to the disease, the cases are often isolated (and this explains why nobody else has caught it in the story).
There are many symptoms of meningitis, most of which I have picked up on in the story. If you would like to know more, I recommend this website: www . meningitis . org (take out the spaces).
