All was silent.

Iruka had ditched Hidan in the classroom about 30 seconds ago and in that time, no one had made a sound.
He had promised to return in 5 or so minutes to check up on him but Hidan didn't want to get his hopes up.
Not with Kakashis reputation for being late anyway… This guy will probably take half an hour to spite me for something this asshole jounin did in the past…
Twenty or so 11 year olds gazed up at him in a mixture of awe and amazement at having an S-rank jounin teaching them.
Hidan shifted his weight onto one leg and a gasp of anticipation ran through the class.
He rolled his eyes and cocked his head.
Another gasp.
He sighed.
Might as well find out what they knew about him…
Hidan was inwardly grateful that he would at least be able to get some information on how to act and what to do from these unsuspecting children as he attempted to teach them something.
He looked out over them, deciding to start with the basics.

"Who here knows about Kaka- umm… me?"

Twenty hands shot up into the air the instant he completed his sentence.
Wow… Popular guy this Kakashi…
And no doubt they all had different stories to tell about him that may or may not be true…
Hidan decided that he probably couldn't trust these kids after all…
Especially if they had ALL heard about him.
That was how myths and legends developed, via the over active imaginations of children.
His eyes rolled up towards the ceiling in exasperation.
Might as well have some fun then.
Time to teach them something that may or may not kill them all…
Accompanied by a demonstration of course.
Hidan rubbed his hands together in anticipation as he asked his next question.

"Who here know how to swallow swords?"

No one made a sound but several hands were raised.
Hidan scratched his head.
Oh yeah, they teach you what to do if you accidentally swallow a kunai in these classes…
That is essentially sword swallowing…
Next idea then!

"Who here knows how to use will power to stay alive after they have been stabbed in a vital organ?"

A gasp and whisperings filled the room.
Hidan grinned.
Struck gold!
For obvious reasons he couldn't actually teach how to survive with willpower unless they became Jashinists, but the way Hidan saw it, it would be funny to demonstrate just to see their reactions.
Pointing to a young girl with white irises in the front row, Hidan said, "You there, what's your name?"
The girl looked up, surprised and insulted that someone didn't know who she was.
With her nose upturned and thinking she was the greatest thing in the world, she replied snobbily,

"I'm Hyuuga Hanabi. I come from one of the most highly sophisticated clans in Ko-"

"Yeah, yeah. I don't give a shi-… Uh… Damn."

Hanabis mouth dropped open in shock.
Who dare interrupt her and not care about her roots?
No one usually, but to be so easily brushed aside by the great Kakashi Hatake bruised her ego greatly as sniggers and giggles came from the other students.
Hidan rolled his eyes at her reaction.
What a little brat…
He would get her back real good for being a snob.

"Fine, Hanabi. Grab that kunai from the desk and come here."

Regaining her composure, Hanabi shrugged her shoulders as if it were no big deal that she had been so easily insulted.
The young Hyuuga walked up to the teachers desk and took hold of the kunai that Iruka sensei threatened to shove down their throats when they misbehaved.
Having accomplished half her mission, she returned to Hidans side and held it out.
Grinning under his mask, Hidan kneeled down beside her, pointed to his chest and smiled wickedly,

"Stab me in the heart."

Hanabi hesitated, not sure if he was serious, but upon seeing an impatient look under 'Kakashis' mask with her Byakugan, located the heart and stabbed the kunai through it.
Hidan noted with glee that she stumbled back in horror at the sight of blood.

She had obviously thought he was a shadow clone that would disappear on impact or some other sort of visual trickery.
Not for a second had she considered that she was stabbing an actual person.

Whimpering slightly as blood soaked through his jounin jacket, Hanabi Hyuuga took a step backwards in fright, her hands incriminatingly soaked with red.
Hidan yanked the kunai out with a grunt, spilling blood all over the floor and nodded to her.
A silence descended upon the classroom as every child held their breath, sure that one among them was going to be charged with the murder of Kakashi Hatake.
Hidan had to stifle his giggles when he held out his arms to their terrified figures.

"See I'm still fucking alive. Willpower brats!"

The reactions were, in Hidans mind, absolutely priceless.
Several children burst into tears while another fainted at the sight of so much blood.
The boy that he had seen earlier, Konohamaru, was several shades paler than he was before and the girl next to him gagged and vomited.
Hidan cocked his head at them and smiled at the sound of crying and screaming.
Hanabi was still frozen with terror in front of him.
Stupid brat…
He remembered reading something once about children having nightmares for years after experiencing a murder or shocking violence.
Good, Hidan thought, now that they are significantly scarred for life, time to get the hell out of here…
His chance came when footsteps were heard approaching the classroom and the door swung open.

"Kakashi? I just came to see how you were doi- WHAT THE FUCK!?"

Iruka slapped a hand across his mouth in shock, whether it was because he swore in front of a class full of children or because someone he secretly idolized was bleeding profusely was up for speculation.
He gasped upon seeing the bloody hole in Hidans jounin jacket and the soaked kunai that had dropped to the floor beside him.
What ever he had expected to return to his classroom to find, it obviously wasn't this.
Iruka didn't think to question why his idol was still standing/alive.

"What the hell happened!?"

Without hesitation, Hidan shrugged his shoulders, pointed to Hanabi Hyuuga and without bothering to elaborate replied,

"She did it."

Irukas mouth dropped open upon seeing Hanabis blood soaked hands and the poor girl passed out with the shock at being framed.

Hidan glanced around at the terrified, and in some cases, passed out children and back to Iruka.
I think its time for me to go…

"Well… Guess Ill be going then… See you later kids, Iruka."

With a cheery wave and a grin on his face, Hidan jumped out of the window and walked to what he hoped was somewhere far away.
