Hit Three: The Wrong Student
Kakashi knew what he needed to do. He knew what he needed to get. He knew what he needed to become.
He needed to protect Naruto.
He needed to get the Mangekyou.
He needed to become one of the monsters he had always hated; one of the people who killed their special person.
Kakashi wasn't stupid; he knew Jiraiya was a strong ninja who would be able to teach Naruto a lot, in both ninjutsu and life skills. But Kakashi also knew that he needed to help protect his sensei's son, even if the boy didn't need it. Even if Naruto came back stronger than him, Kakashi had to do his part.
So he would do the vile thing, and get the Mangekyou.
He had planned this day meticulously from the start. As soon as he heard Naruto was leaving the village, Kakashi knew he would have to get stronger as well. As with everything else Kakashi did, this plan was detailed, thorough, and had no pitfalls.
Regrettably, Kakashi would be able to gain the Mangekyou with ease.
He had already tracked down his target—calling the person a 'friend' or any other term that implied closeness would only make this more difficult. Although, Kakashi supposed that was kind of the purpose.
He shook his head to clear these thoughts away. Such speculations were useless. What must be done must be done.
He was outside the place where his target was. Pakkun and Biscuit had confirmed it two hours ago, and Kakashi had come immediately. Tsunade willingly gave him permission to complete this mission; she knew as well as he did what had to be done, and she was just as determined to ensure Naruto's safety as he was.
There were no lights on in the windows of the building, which was odd. The establishment was a hotel, so surely someone must have been awake to welcome guests? Unless this wasn't the right place, or his target knew and suspected him of coming here…
No. That was impossible. There was no way the target could already know of this. They weren't planning an ambush. Most hotels in this city were closed, having accepted their last guests at eight this evening. Sure, it was a strange coincidence not lost on Kakashi that all the guests happened to be sleeping at once on the night when he came to kill a certain man, but he wasn't going to speculate on it.
He had already decided speculations were useless.
He climbed up the wall, using his hands rather than his chakra, and peered cautiously into the room from the window. Good. It was just as he thought. The target was alone in the room; his guardian was probably out enjoying the local nightlife.
Slipping the window noiselessly open, Kakashi climbed through and walked to the figure sleeping deeply on the futon in the middle of the room.
He allowed himself one tear for what he was about to do, then he pulled out the vial Tsunade had given him, and poured the poison into the mouth of his target. This way, the boy could die in peace.
Kakashi did not want him to suffer—not as Kakashi was suffering, just thinking of doing this. Completing the task was so easy and so hard at the same time. If Kakashi were to talk to the target that lay on the futon swallowing the liquid, he was sure the boy would agree of the importance of his death, but that was not exactly a comforting thought.
From the hallway came the sounds of a drunken man climbing the stairs. Kakashi needed to leave soon. But he had to make sure this worked.
The door handle turned slowly, and Kakashi was hidden out of sight before the drunken man outside had even begun to push the door inwards. A light flicked on, but the boy on the mattress didn't groan or instinctively cover his eyes.
To the drunk man, it looked like his comrade was deep asleep.
To Kakashi, it looked like Tsunade's poison had worked. He was not relieved by this news.
His eyes were heating up oddly and as he reached a hand up to touch them, he realized in shock that he was bleeding. The effects of the Mangekyou? he wondered.
The white-haired man seemed to notice there was something wrong with his charge, and he knelt down beside the boy and poked him. "Hey, wake up, brat," he said in a surprisingly clear voice for a drunk.
Well, it wasn't that surprising considering he was a ninja of very high caliber.
"Brat? Are you asleep?" the man asked.
Kakashi swallowed. The boy... is blonde? he asked himself. He looked at the poison vial in his hand. The poison he had just poured down the boy's throat... had no antidote. It was a special mix created by Tsunade to be undetectable and irreversible.
Earlier, that had seemed like a good thing.
Currently, Kakashi was trying desperately to not have a heart attack. Shit! I just killed...
The old man checked the boy's pulse. "Crap, his heart isn't beating!" he said aloud.
Oh my god...
"He's not breathing... Who is in here? Who has done this?" the man asked, turning around in a rage, already retrieving kunai from his weapons pouch.
Kakashi couldn't hold it in any longer. He freaked out. "SHIT! He's dead! I killed NARUTO! I killed the wrong damn student!"
Jiraiya turned to him. "Kakashi, you did this?" he asked in surprise. "You-you killed Naruto?"
Kakashi nodded numbly. "I... I had to get the Mangekyou. It was supposed to protect him. And now he's dead. Oh my ramen kamis!" He curled himself into a ball for comfort. It wasn't working. "My foolproof plan! No! I killed the wrong person!"
"Who did you intend to kill?" Jiraiya asked menacingly.
"Sasuke! I heard he was here… Orochimaru had a beauty pageant…"
As Jiraiya puzzled over this, Kakashi sobbed himself asleep. He had the Mangekyou, but now what good was it?
