AN: I don't think Kazuki counts as a Gary Stu, I write him in a way that the reader is supposed to hate him and want him dead. Isn't that completely the opposite?
Hidan was caught off guard by the question. Kakuzu had been deep in thought while eating. "Huh?" Hidan murmured.
"I want to make sure you two are far apart," Kakuzu answered, looking down at Hidan. "You should keep your scythe by your bedside, and sleep with clothes on."
Confused, Hidan sat on his bed. "Why the fuck do you care?"
"..." Kakuzu replied with silence, and sighed. "I'll move my things in here."
The white-haired man lied across his bed as Kakuzu left. There was really no reason for Kakuzu to care if Kazuki did anything, after all, and he would just remind him of Kazuki anyway - so wouldn't they be better off apart? He rolled on to his stomach. He hated confusion, a lot. When he didn't have a clue about something, it made him feel as if he didn't have a clue about anything. They should just have gotten on with their lives as normal.
Soon, Kakuzu's bed and desk had been pushed into Hidan's room, and everything that came with them. Hidan was quite fed up. He didn't believe anything was going to happen again, and Kakuzu was expressing pointless worry. "Kakuzu, there's no fucking point in this," he stated, kicking back and laying against his pillows. "It's not as if-"
Slapped across the face, Hidan was interrupted. "Hidan, don't let your guard down," Kakuzu shouted fiercely at him, moving his hand gently to the preacher's shoulder. "Don't let your guard down, it's not proper for a ninja," he repeated. Hidan stared up at him, bemused. Kakuzu averted his eyes, uncomfortable.
The awkward silence surrounded them. Hidan lied back in his bed, trying to get his mind on to other things. Fuck, that cereal tasted bad. Wonder how old Kakuzu is, a hundred? I should pray pretty soon. What the fuck is up with Deidara's mouths?
Kakuzu sat up, staring into space and taking his mind off of the events. We wasted money on that cutlery. Wonder who's the highest bounty at the minute? I could use a good, well-paying job.
Neither of them bothered to break the silence. It would seem more awkward to speak to each other than not to. But Kakuzu's thoughts steadily wandered back on to the topic.
Wonder what Kazuki's bounty is. Wouldn't mind collecting. Kakuzu smirked to himself, and Hidan stared oddly.
"Yo, miser," he yelled. "What's so fucking funny?"
The idea of killing his brother was quite a good one to Kakuzu. "Nothing."
