Chapter 1: New Sensei

On this fine day, one curly-haired Bovino Lambo didn't know what to do.

This morning, on the announcements, Hibari-san had announced that old Nezu-baka was being replaced with a new teacher and his co-teacher.

At that exact moment, said Nezu-baka walked inside the classroom, an eyebrow twitching in annoyance.

"All right you brats, shut up already! I'm already pissed that two idiots are going to be replacing me, an elite! Some brats from Italy are going to teach this class instead of the great Nezu-sama!" Nezu bellowed.

'Italy? That's where Tsuna-nii's at, right? Maybe he's coming here? But then, who is the other person?' Lambo pondered, but then gave up. 'I'll find out soon, anyway.'

But the rest of the class wasn't going to give up so easily.

"Dame-sensei! Who are the substitutes?" Mochida Tezuka asked.

"Yeah! We want to know!" Haru Sakuno exclaimed.

The class nodded their heads in agreement. They wanted to know who would finally replace Nezu-sensei.

The door to the classroom slid open loudly, revealing the Vongola Cloud Guardian in all his 'I'll-bite-you-to-death" glory.

"W-what d-do yo-you need, Hibari-san?" Nezu asked nervously.

"I'm going to teach the pathetic herbivores how to act with their new teachers." Hibari said in his usual tone of voice.

Seeing that Nezu wasn't moving, Hibari spoke again.

"Is that a problem, pathetic no-good herbivore?" Hibari asked dangerously.

"N-not a-at a-all, H-Hibari-sama!" Nezu said, scrambling to the safety that was under his desk.

"Hn. Commiserate as always. Anyway, you lot, " Hibari said, his tone still dangerous,

"Had better behave yourselves around the omnivore and the monkey king."

The class gasped inwardly. 'An 'omnivore' and a monkey king are going to be out new teachers? Goodbye, my sanity.' They thought.

Lambo didn't gasp, though. The information just given had confirmed his suspicions that one of the new teachers was his Tsuna-nii. Who else would Hibari call an 'omnivore'?

And if the 'monkey king' was who he thought it was, then his classmates were in for a major surprise.

*~The Next Day~*

Lambo's class was buzzing with excitement. Their new teachers would come today, after all.

The door slid open for the tenth time already, and the class didn't notice two men step inside. The class finally shut up when they were greeted by a burst of amber-ish flames from two guns with large 'X's on them, blasting a hole into the next classroom over.

"Shut the fuck up, trashes. You're making my head hurt and my ears bleed from your irritating voices. Do the world a favor and SHUT THE FUCK UP or I'LL DO IT FOR YOU!" one of the two men yelled in a gruff voice.

Ahaha? I know that I should be working on I and X, but... Writer's Block and lack of time... Ahem, I hope you guys enjoyed this! This will be like a side project, since I'm focusing more on I and X...
