A/N: I was too lazy (and it was too long) to update I'm Not Don! so I did this instead.

This gives a taste for Humor ahead in it so I suggest you check it out~

Plus I had an epiphany: Hey does Reborn have (m)any Self inserts?! And low and behold this was born! From my collection of short series of Self inserts. I might continue if there is interest, follows review etc. Personally I may just continue this one on my own because it was hilarious to write.

Warning: A lot of Destruction. Occ Reborn. Parody and Cracky craziness.

Subject: A young fanboy of KHR who thinks everything is just to cool! Where Reborn literally become a kid again in both mind and body. I don't own Katyeko Hitman Reborn

'Thoughts'

Reborn as Reborn!

Victim 1: Scaring Shamal

It's not always easy being a kid, but I bet it's even harder being an adult.

Julie, age 11

In an obscure town, in an expensive hotel there was maniacal laughter, perfume, broken glass, dented walls and bullet holes littering the walls. To put it plainly total and utter destruction.

In the middle of this was a young barely 3 child. Oh and a doctor cowering behind the couch for his life.

This doctor's name was Shamal. A rather prominent mafia doctor in fact who's mafia nickname was Trident Shamal.

The esteemed man at this moment was cowering behind the rather nice and expensive couch while mourning why had he chosen such nice place to perform the operation on?

How had a mafia member ended up cowering behind the couch because of a destructive three year old child? Let's go back to a couple of hours ago...

Flashback

"You had a woman over here" said an unimpressed Reborn in baby form. When Shamal shot him question looked that screamed "How did you know?"

Reborn gave the look and tipped his hat over his eyes "I can read minds"

"Uh ah of...course" squeaked Shamal as he nervously waved Reborn over to the kitchen table to sit.

"That and the woman's perfume is stinking up the whole room" pointed out Reborn blandly as he hopped onto one of the kitchen chairs and Shamal choked midway while he prepared the medication to erase Reborn's memory.

After he had recovered Shamal came over needle in hand "Are you sure? After this Reborn you know all your memories will be erased and the results are unknown" forewarned Shamal

"Just do it. I have a job lined up" curtly replied the strongest Arcobaleno wishing to get this over with, so he wouldn't have to bear the humiliation of being an adult in a kids body.

Shamal nodded, gulped, and administered the memory wiping drug. It made Reborn blink drowsily before falling asleep a spit bubble growing and shrinking from his mouth.

Shamal put him into the hotel bed before making a couple calls to his lady friends and flirting over the phone. He sadly couldn't leave until Reborn had woken up, given him the rundown as a amnesiac man in a baby's body, and given him his job information.

Flashback End

That was the last time Shamal saw Reborn calm, in control, mature and overall like a grownup. 'Had he done something wrong and was Reborn now reverted to the mentality of child by wiping his memories?'

It sure seemed like it. The reality was yes and no. Though Shamal, poor soul would never know that.

Skip now to another world. There is your generic barely a teenager boy who loves action anime, sweets and gaming. A kid still high on life, sweets,and the unflappable notion that: 'Hey I'm a kid I can't die!'

Except that he did. Not that he ever realized (but that is irrelevant at the moment).

Now imagine this boy in a adult's body.

Now imagine this boy reborn as The Reborn. Originally an adult shrunk into a baby's body. Now presto! It's a preteen kid in overpowered baby's body!

In fact the World's Greatest Hit man's body. Starting to makes sense now?

Well as what can be imagined that is Shamal got: A hyper bouncing off the wall

kid in the worlds great hit man's baby body.

"This is worse than when I was training Gokudera" bemoaned Shamal watching as Reborn jumped around like a hyper dog breaking and ripping up stuff because he simply could, but unable to do much because Reborn was that scary.

He was the world greatest hit man. The world greatest hit man who seemed to leave behind all his rationality and common sense. Now, acting like the child he appeared to be.

Let us all take brief moment to mourn for the world future and our own sanity. Like how Shamal was doing right "STOP! I don't have enough on me to pay for the damages and my date!" with anime tears dripping off his face in the most manly way.

No use. The kid was on perpetual high from finding out. "HAha take that I'm the strongest!" and "Awesome I'm in Reborn's body!" and "I wonder how many things can I smash before I get tired of it?!" accompanied by menacing cackles.

Then as he was about to throw Reborn's now his hat in the air cowboy style he proceeded to find Leon clinging his hat.

"AWESOME IT"S LEON!" who he proceed to pick up and turn into multiple shapes and weapons, because he could and started smashing and shooting stuff like there was no tomorrow.

This was all accompanied by what he deemed was awesome sound effects "POW POW!"

Shamal paled in terror at the sight while dodging the debris and bullets. If Reborn could do that much without Leon- because yes he had already broken 4 windows, thrown a table and 5 chairs out he windows, ripped up the carpet and then smashed 34 plates and much much more before.

"Stop! Reborn ...I ...I.."desperately Shamal picked up the manila folder that sane Reborn had given him to give to amnesiac Reborn "I have a job for you! and need to tell you some things"

"A job?! Lemme see! Is it awesome? I know it is!" Poor Shamal was now bombarded with questions every second by Reborn who had previously acted like he had not existed.

Thus Shamal was stuck reiterating Reborn's life to Reborn himself complete with 'awesome sound effects' and storytelling gestures . (He missed his date, by the way which he mourned later with chocolate ice cream and bad girly soap operas.)

"So what's my job?" asked pumped up and amnesiac Reborn. Who had slid the paper out of Shamal's hand without him noticing.

"Hey Reborn?!" Squawked Shamal in surprise before muttering "Well, at least you retained your hit man skills for better or worse" at this he paled at the sight of the destroyed room the numbers for damage adding up in his mind.

Reborn's excited expression was replaced with a gloomy one as he saw the assignment printed in clear black type "Aww tutoring!" whined the new Reborn kicking the floor in disgruntlement "I don't want to go to school!"

"It's for the up and coming mafia boss, Dino Cavallonne of the Cavallonne family" explained Shamal hurriedly, because other Reborn would not be happy if present him denied it.

"Dino Cavallone?" Interest peaked and a smile began to spread as the kid's mind in the baby's body began to whir.

Now let us cry for the poor soon to be student(s) of the now preteen hyper action loving kid in a baby's body, that can now actually pull off those great , jaw dropping, and fear inducing feats of power and strength.

"Plus" added Shamal in uneasy attempt at comfort, because Reborn's face really did look like a kid who had missed out on ice cream "You have plenty of time in between to do other stuff" not seeing Reborn's slowly spreading maniacal smile.

"I know, I could take over the world!"

Yes let us all mourn.

A/N: I'll have you know I was smiling maniacally while typing this. I hope you all had fun reading this as I did writing it too. :D . I appreciate any Reviews, Follows and favs~

It will encourage me to continue writing this while keeping up with my other I'm Not Don! Fic. Plus it gives you a taste for the comedy ahead I'm intending for it!.

Hyper reborn preteen kid+ baby's lack of inhibition + adults knowledge/power= What do you think~?
