Scene Start

Here we see 3 random genin on their first D-rank mission. Their Jounin-Sensei was nowhere to be seen.

Random Genin #1 says, "What did our Sensei tell us to do again?"

Random Genin #2 says, "We're supposed to be cutting these trees down into logs."

Random Genin #1 says, "Ohhhhh! Well then, let's get to it, shall we?"

3 AND A HALF HOURS LATER

Random Genin #3 says, "Maaaaaaan! I'm soooooo tired!"

Random Genins #2 says, "Me Too, maybe we should take a break."

All 3 Random Genins go off for a lunch break leaving a pile of 37 logs left which all poof away only to return in various dismembered ways.

SAME TIME, VALLY OF THE END

Naruto was looking around for Sasuke who had disappeared after their fall of the monuments. Naruto heard the chirping of birds right behind him and readied a Kawarmi.

"CHIDORI!" Sasuke screams as he thrust his lightning-filled hand towards Naruto from the water.

"Kawarmi no Jutsu" yells Naruto as the Chidori nears him.

Sasuke's eyes narrow a fraction of an inch, expecting Naruto to Poof away and reveal a log. There was a poof of smoke. Sasuke continued to near Naruto with his Chidori. As the smoke clears, Sasuke's eyes widen comically as he sees Naruto still there and his Chidori about to enter his head. Naruto's head turns around in surprise that his kawarmi didn't work and looks straight into Sasuke's soul through his eyes as-

Squelch

Sasuke's Chidori completely obliterates Naruto's head and splatters brain matter all over Sasuke. Sasuke's mind froze at the act he had just committed. And as his eyes started to cry blood signifying the awakening of the Mangekyou Sharingan, His mind rebooted thinking 'Oh my god, oh my god, oh my god, What the Fuck have I done? I just killed my motherfucking best friend! What am I gonna do now? He was like a brotha froma notha Motha to me!' Sasuke then sees and explosive tag sticking out from Naruto's weapon's pouch, Sasuke then takes the explosive tag and sticks over his heart. Sasuke takes one last look at Naruto's headless body before steeling his will and activating the Explosive Tag.

SCHLICK

Turns out it was a special kind of explosive tag that removes everything in an 8 inch circle behind it. Sasuke slumped to the ground with a huge gaping hole in the middle of his chest.

Somewhere in Alternate Universe

Author says, "And so, here we have two best friends, one losing his head a because of his friend and one who doesn't have a heart. All Because three random genin got tired of their D-rank mission cutting Kawarmi logs."
