Jiyū watched the bubbling green chakra form around his target. It was thick and viscous like a liquid. However he could feel the heat radiating off of it. Tails began to form from it near her pelvis. Truly the fight against a Jinchuriki could finally begin.
'The beast has emerged. Which means lightning won't work. However…' His hands blurred as he slammed them onto the floor.
"Earth Style: Mud Draco!" The stone floor liquefied as dragons made of mud shot out towards the Jinchuriki. The tails made of chakra burst to life as they flapped rapidly. Pulling strength into her legs, she rocketed into the air to dodge the dragons. Two splattered into a heap of mud as a third turned rapidly to follow her. The green cloak of chakra seemed to have a mind of its own as an arm burst from her chest and slammed the final dragon, destroying it as mud went in all directions.
Finishing off the mud she turned her attention back to Jiyū, only to find him in the air weaving through more hand signs. "Fire Style: Fireball Jutsu!" The flame hit as it ignited the cloak. She began to scream as her voice became distorted by a beastly wail.
'So I was right, the beast's chakra is infused with the wind element. Good.' Weaving through another set of hand signs, the mud scattered across the hallway began to glow crimson as the heat in the area began to increase. "Fire Style: Mud Mine!" The mud exploded with great force as the jutsu went off. The mud on the cloak began to glow as she had just enough time to throw the chakra off her, exploding mere seconds later.
The force of the attack blew her back to the ground with a crash as the ground underneath her began to glow. 'The mud!'
Jiyū watched the large explosion erupt the floors as they shattered. The hospital shook, windows shattered, and the structures east side caved in. He looked at the destroyed part of the building as the smoke obscured his view. "Where are you?"
A chakra arm flew towards him. He dodged the attack. Another came as he weaved out of its way. More and more seemed to chase him as he ran through the halls of the hospital. They broke through walls, floors and ceilings as they tried their hardest to capture their prey. Jiyū wasn't worried.
Attack after attack came flying as he dodged out of the way. He felt his feet be grabbed before he was dragged through the air and slammed onto the ground. She smiled at seeing him fail to run. The poof of smoke that followed however only enraged her. "Shadow Clone? So he's likely from Konoha. That along with the fireball jutsu means he's an Uchiha. If he's hiding his face that must mean he's trying to put me under genjutsu. I can't look at his hood."
Black ink began to form from the clone's location. It rocketed towards her as she flew away from it. 'What is that? A sealing jutsu?' The glow of fire illuminated behind her. She dodged it just before impact. "Damn!" Her heartbeat stopped for a moment. 'No, not yet.'
She fell to the ground. Blood poured from her mouth once again, this time in waves. Her body was at its limit. 'Please hold on!' The Seven Tails pleaded, however she knew the truth. 'I can't. I'm at my limit. I won't be able to keep going.' The sound of footsteps echoed through the area. He was coming.
'Then if there's no other way let's go into stage 2. It may kill you but at least he will die with us.' She smiled to her old friend. 'Alright then.'
He approached her slowly, not like this was all that dangerous. Weaving through the hand signs for the fireball once again he felt the ground tremble. "What's this?" Black and green chakra erupted as the rubble in the area was launched away. "What!?"
He covered his face to stop any debris from hitting it. A roar erupted out as a black and green arm shot towards him. It came too fast as it grabbed him. The force was incredible as it slammed him into an outer wall of the hospital. He coughed up blood before puffing into smoke. The black ink formed from the clone's spot as it began to form lines in multiple directions. In a hidden spot he looked at the beast that now stood where she once had been. The creature made of green and black chakra was humanoid, only it had six wings and a single tail. Spikes covered various parts of its back but the head was the most important part. It wasn't a human's head but that of a beetle.
It was still for a moment, likely searching for its quarry. It's head snapped to one of his clones as its arms extended to crush it. The clone stood no chance as multiple arms extended out of both arms, targeting the other clones in the area. One by one his clones were obliterated as he watched in amazement. "This is their power?" Its head jolted to look in his direction. "Shit!"
Arms appeared from the rubble as he dodged them. He weaved through hand signs as he took in a deep breath. Exhaling, a dragon of fire erupted forward to meet with the arms. "Fire Style: Flaming Draco!" The attacks collided as an explosion erupted. He looked into the smoke, wondering what won. "Shit!"
He tried to dodge the claw that hurdled towards him. He wasn't fast enough as it slashed through his clothes and met his skin.
Blood gushed out as he grabbed at the wound. 'Damnit! That chakra, it's not like the last one she had. It almost feels like it's a poison.' Falling to the ground, he couldn't believe the intense pain of the chakra that coursed through his body. 'I need to purge it before…!' His head whipped to see the beast as a massive chakra signature flared to life. A black ball of super condensed chakra was forming above its mouth, smaller chakra particles intermingling into it.
The ball was being condensed more and more until it was the size of a baseball. Once at that size, it pointed its head in the direction Jiyū was slumped over before firing the Tailed Beast Bomb. It whizzed through the air at an alarming speed before exploding, destroying the hospital and all within.
Steam escaped its open maw as it roared into the air in victory. Fire, smoke, rubble, nothing was left untouched by the destruction of the beast, and now even this man knew what a Jinchuriki was capable of. Tears formed in her eyes as they evaporated into steam. She could feel her body breaking inside the chakra armor made by the beast. Her skin was long gone and once she released this prison she and the seven tails would die. She didn't regret it though. She would rather go out fighting than in a bed. Any shinobi would.
"So this is your power, Jinchuriki." Concrete slabs rose as Jiyū arose from the dead. He tried to steady his breath as the beast looked at him in surprise. 'If I hadn't put up a mud dome at the last second I would have been done for. What's more, I can't attack it with my bare skin if I wish to not be poisoned and burned. Which leaves only one option left.'
He smiled. It was only recently that he gained this form back, but he was so glad when he regained it. "I haven't gained my full power." His skin began to change as red scales formed over it. "To be honest, I don't know if I ever will again." His nails lengthened, his hair grew until it escaped his hood. "But even if it can't regain it all, this should more than suffice." His mouth grew into a scaled muzzle. Two horns began to grow out from his skull, reaching out past his hood and pointing to the sky.
Red shined from the hood. The eyes of a demon who had finally awakened. "Now Jinchuriki, let me show you just how powerful I am."
