Shimazaki, Kiyoshi Shimazaki, Kiyoshi || When the kage extended his hand for the scroll; the messenger allowed him to grasp it. Time seemed to freeze for a moment before the messenger released his end of the scroll.  After the transfer was complete the man took a step back and allowed the kage to open the scroll.

Within the scroll the words were illustrated,

"Ziare sends his regards."

Immediately the kage would feel an unbearable pain take fire within the hand that was used the grasp the scroll. This pain quickly began to spread across his body as his cells were being targeted and devoured one by insects that rapidly multiplied.

As soon as everything was in motion; the messenger aimed to get as far away from the kage as possible before the reality of the situation dawned upon him.
Midou, Kei held the scroll for a moment, suddenly he began to feel a burning sensation in his hands. He instantly dropped the scroll, feeling a sense of rage. His eyes darted over at the genin as the insects began to feast on his flesh. "What the hell is this!?" He shouted, kicking off the ground and launching his right hand into the genin's throat, gripping it with enough strength to make him feel the fear of death.

Without wasting a second, he pinned the shinobi down onto the ground, holding him tight. The nano insects continued to travel through his arms, and as it did so his medical senses began to kick in.  His chakra began to flare throughout his body, sending waves upon waves of rejuvenating energy.  His cells began to multiply and recreate at a speedy pace, combating the poison that infected his body.

His anger knew no bounds as he continued to apply pressure into the genin's neck, aiming for answers. "What is this and tell me now before I tear your head off right where you stand and send it as a message to your Kage," he roared.  His lazy and carefree expression was now gone and replaced with that of a blood filled lust.

The unknown reagent continued to burn through his hands, all while his own chakra combat against it. Every instant a cell ceased to function, two more would come back. The only issue with such a technique was his supply of chakra.   Quickly, he turned his head over towards his group of shinobi, "Quick, seal that scroll! Don't touch it at all, it's dangerous," he roared, gritting his teeth.

The pain was excruciating, but he had to endure. The action that the Mizukage performed spelled war for the two village.
Shimazaki, Kiyoshi || The boy was crashed into the ground, but moutning him was perhaps the worst thing the mizukage had done. By this point the boy's entire body was covered with the insects and they were continually transfering over to the male atop him. The problem with his method of healing was simple; the bugs would continue to spread and multiply so long as they had cells to feast on. You couldn't simply overpower them by making more cells. This only gave them more food that'd allow them to continue and grow.

It was also notable that due to the kage's body remaining in constant contact with the boy; the insects continued to be transmitted. The boy himself saw his life flashing before his eyes. He knew he stood no chance against the kage, but he also knew his duty. He knew from the moment that he was assigned this mission it was for the bigger picture. This wasn't about the boy himself, or his physical ability. He was like a chess piece being sacrificed to gain a larger advantage. His gift made him a valueable asset in this.

Due to his neck being crushed the boy didn't speak. If he had any strength left within his body he'd place his bare hands against those of the kage's that was now around his neck. The boy's stare was unwavering. He did not feel fear in the situation and had come to peace with what was happened. He'd been raised in blood and sweat and was mentally conditioned to see death as nothing.

His heart was cold and the kage may even notice that his body was as such to the touch. At the current state the boy's fate was as sealed as the kage's,

<I'm sorry Lord Mizukage...I won't get to turn this one in...>
Shimazaki, Kiyoshi it was to note that the pain quickly engulfed the entire body of the kage.
Shimazaki, Kiyoshi says, You...have been infected...by my special...friends. There is no...cure...you will perish...as so will I...
Shimazaki, Kiyoshi says, We're not like you...
Okata, Ren arrived on the scene at the gates. With Ren's own eyes, he simply spotted the the Kazekage in action and the scroll he yelled about. Within a simple instant, he acted, not even stopping to question the wors he spoke.

His bodied carried itself forward and Ren simply presented another scroll, choosing that it would be best to seal the item into another object of sorts. With ease, a basic sealing formula was planted amongst his own and he pressed it towards the other---effectively sealing it away.
Midou, Kei hearing the man's words only caused him to rage.  He clicked his teeth before lifting him up with his single arm and throwing his body full force into the walls of the village.  A loud explosion echoed the desert as rocks shot out from the impact zone.   He let out a mighty roar, expressing his rage at such an attack.

"KILL ALL OF KIRIGAKURE! LEAVE NO TRACE OF THE SHIT HOLE BEHIND!" His blood boiled, and he was nowhere near finding a solution to his problem. It seemed as though death was coming for him, but he was persistent in escaping it.  There had to be a way, but he didn't know how.  His only means of combating the issue was to slow it down for the time being.   He glanced over at Ren, and the other shinobi.  His eyes were filled with a head tearing rage.

Suddenly, he began to burst into laughter. His voice echoed through the sands. For a moment, it sounded as though he had gone mad, but in reality he was far from mad. He had no reason to contain himself anymore.

The Kage gave a sinister grin to the two men. "I want everyone in the square, anyone who avoids it will have their headband removed. We are at war gentlemen."

A malicious aura soon overcame the kage. His chakra continued to fight off the venomous plague that riddled his body. The option of defeat was something he wasn't going to take.   He glanced at his hand, taking note to its coloration, and instantly knew that it wasn't going to be good. "Tch, where's Onbu?" He shouted, gritting his teeth at the intense pain.

"Fuck it!" He added, not wanting to wait. Without a second's thought, he extended his right arm forwards. He swallowed hard before severing it from the forearm downwards with a chop of the left. Blood began to spray out from his arm, but he quickly began to apply chakra to mend the bleeding, creating a stump.

The detached arm flew into the air, spraying blood all around before it landed on the ground.  It twitched for a moment before the insects took over, completely turning the detached limb purple.
