Rated for shounen-ai, death and Kankurou's language. I think there's more to this, but maybe not... We'll see how it goes. It could sort of stand alone like this, so...
"Inuzuka, aw fuck, Inuzuka, why the hell did you take that shot!" Kankurou moaned, his hands clasped around one of Inuzuka's as Sakura used healing jutsu to try to stop the bleeding.
Kiba grinned weakly. "Because otherwise you would have taken it… You were going to… to throw your life away," he murmured, coughing weakly. Blood came up, alarming Sakura and Kankurou.
"I was prepared! Besides, I intended to dodge a critical hit! Now you're just…. Just weakened by it!" he sobbed, unable to accept…
"You wouldn't have been able to in time… I know you, Kankurou. I could tell… you weren't going to dodge it… you were relying on your puppets, but they weren't going to make it…" Kiba said.
"They're faster than you think, Inuzuka!" Kankurou complained.
Kiba sighed. "Kankurou-koi… I'm dying…"
"No, you're going to be fine, Inuzuka-koi! Sakura-chan's a great healer! Almost as good as Tsunade herself and,"
"Kankurou… Please, listen. I don't think…. I don't think I have much longer…" Kankurou felt tears gather at his eyes and he squeezed Kiba's hand. "So… while I'm here… There's just a few things… I want to say… and ask of you…"
Kankurou nodded. "First… Can you call me by my given name for once?" he asked, smiling weakly and wincing as a wave of pain rolled over him.
Kankurou tensed seeing Kiba like that. "You're not going to die, so I can call you whatever the fuck I want! Don't you dare fucking die on me, Dog-boy! Don't you do this to me!"
Kiba sighed. "You're so fucking stubborn, Kankurou… But, I also wanted to say… You're right…" Kankurou eyes widened. "Your face paint is better than mine…"
Kankurou broke down into sobs as Kiba reached up to stroke his face. "You stupid bastard! I don't care about that right now! Hell, I'll even do my face paint your way if you'll just promise me you won't die!" he begged.
Kiba smiled morosely. "No… I can't promise that… I'm… I'm sure I will," he said, huffing. It was starting to get hard to breath… His eyes were getting cloudy…. Tunnel vision… "Besides, I'd rather you do it like you've always done…"
"Damnit, Inuzuka! Damn you, Kiba!" Kankurou growled, holding Kiba's hand to his cheek. Their hands were trembling… They calmed slightly as Kankurou interwove their fingers.
"Thanks…" Kiba said, smiling. He could feel Kankurou's tears. "I want you to know… You'll be all right… I'm just starting a new mission… I'll hold a spot for you on my team, okay? Just… don't rush… to meet me… I'll wait for you…" Kiba's eyes were open but he couldn't see anymore, everything was black… Except two brilliant green eyes, wide and tearing with sorrow. "Won't you smile for me…? One last… time?"
Kankurou grinned weakly. "You always ask me to do the stupidest shit, Kiba… God, you're such a dumbass…"
Kiba's eyes slid shut. "Yeah? Say… whatever… you like… I still got… a sexy suna-nin…" he said, laughing weakly, hi slaughter turning into a coughing fit.
Kankurou pressed Kiba's hand firmly to his cheek. "You ended up luckier than I did… I just got a stupid… a stupid, crazy Konoha-nin!" He laughed. "There's no way you can die, Kiba… You're too stupid to learn a new trick lie playing dead… and Sakura's a great healer… Don't you fucking die!"
"Love you… Kankurou-kun…"
"I know that!" Kankurou yelled, holding onto Kiba and trying to give him some of his own life, adding his own healing jutsu to Sakura's. "I know that…! And I love you too, you damn, fucking idiot!"
"Good to know…" Kiba murmured…
"Oh… God… Kankurou-kun, I…" Sakura-chan faltered. "His body's rejecting the jutsu now… He's… He's…"
"He's NOT DEAD, damnit!" Kankurou roared. "He's close, but he's not! We… We just have to get him back to Konoha…. Tsunade-sama can heal him! Let's go, we're wasting time!" Kankurou hastily wiped away tears. Kiba's hand was cold…
"Kankurou…" Temari placed a hand on his shoulder.
"What, damnit?" he asked, sniffling.
"He's dead… He knew it, too…. That's why he told you those things, and asked you to call him Kiba… Let him go, Kankurou…" She said softly. "Others important to us have been taken for lesser reasons…"
Kankurou nodded slowly. "I'm not leaving his body here…" he said resolutely.
Temari tensed. "Kankurou… Are you sure you want to carry back a…."
"Don't say it!" Kankurou interrupted. "I'll… I'll accept that… that he's not coming back but… don't say that!" he pleaded, shaking.
"All right… Let's go, everyone," Temari said… She'd been team captain for this mission, but she wished Shikamaru had been around. This mission would have been perfect for him… She'd cost her brother his lover… She felt like shit… And she'd really liked Kiba too… The two of them had been so great together…
She lead them away from that forsaken country: her, Sakura, a stray chuunin that had come along and Kankurou carrying Kiba and Akamaru.
Kankurou shook as he became frighteningly aware of the fact that the body he carried was just that, and no more. He hurried to the Inuzuka house, feeling more and more like he was going to gag. How horrific, the shell of his beautiful, dumbass dog-boy so pale and cold in his arms! How could such a vibrant being leave so abruptly, how could his body be so cold as stone and lifeless in such a short time!
He knocked on the door, his entire body trembling, eyes wide and teeth clenched. It was a moment before his sister opened the door and gasped at Kankurou's burden, her hands going to her mouth. "Mom!" she yelled. "MOM!" her tone was frantic.
The Inuzuka clan's matriarch came running, already guessing. Her daughter wasn't one to cry wolf. There were only a few things it could mean… She prayed it wasn't…
"Kan-Kankurou-kun!" she stuttered, taking the body from him. Kankurou was almost reluctant to give it up, as much as it chilled him to the bone to carry Kiba and Akamaru when they were like that…
He swallowed deeply, trembling like a leaf in a gale and finally passed out, falling into Kiba's sister's quick arms. "Get him in a bed, and warmed up!" Kiba's mom said, carrying Kiba's body away. Kiba's sister ran to do so, setting Kankurou up next to a big fire and piling blankets on, rubbing warmth into his frigid hands.
