A/N: Ok this one is an AU! It's also my FIRST EVER AU! Not much of a HieixMukuro fic, but still a slight pairing. As always PLEASE R/R!

Pinky Swear:

"Ok children let's go outside for recess!" The distressed young teacher called to her kindergarten class. She loved her job, but sometimes the kids just go so wild, and she prayed for the short thirty minute break she got after lunch where the children went to play outside. The children scrambled through the halls as fast, and as orderly as they could in a straight line.

"Ms. Boton!" She heard her name called by one of her kids that was tugging her hand.

"Yes Keiko what is it?"

"Me and Yukina are going to go play on the swings! We need someone to push us!" She looked up with pleading eyes at the tired teacher, tugging her sleeve again.

"Why don't you go ask Yusuke or Kuwabara?" She tried to suggest, but knowing that the boys probably had other things in mind.

"Yusuke's too mean! He's always picking on me! And Kuwabara has icky cooties!" Boton rolled her eyes, but didn't want to give into the littler girls puppy dog eyes, this was her only break for Pete's sake!

"How about Hiei?" Boton felt her other sleeve pull, looking down only to find Yukina pulling it.

"Yes, ok that sounds like a wonderful idea doesn't it Keiko!" Boton looked down cheerily at a slightly disgruntled Keiko who thought for a moment before nodded up smiling.

"Ok, um, let's see…" Boton looked around at the children who were now scattered around the small school yard.

"Where is Hiei?" Boton counted the students, noticing she was missing one.

"Where did he go!" The panicked teacher looked around, calling her young students name, yelling at the other students to try and find them.

…

Hiei relaxed against a tree trunk, sitting on one of its high branches. He could hear his name being called, but made no effort to acknowledge them. He closed his eyes, wondering how long it would be until they eventually found him, hoping it wouldn't be for awhile. His wish was not granted however, when a small ginger popped her head up.

"What are you doing up here, Hiei?" the young girl looked directly in his eyes, clearing passed the years of innocence, but still young however in her actions.

"Go away Mukuro!" Hiei glared at her.

"Why?"

"This is MY tree! No girls allowed!" Mukuro thought for a moment, still holding onto the branch Hiei was sitting on, but hadn't pulled herself up yet, humoring him until he gave the ok.

"I'll give you my gummy bears if you let me come up," She tried, not really thinking it would work.

"Ok,"

"What?"

"I said ok! But you gotta give them to me as soon as we have snack time!"

"Deal," Mukuro pulled herself up in one swift movement to where she was sitting across from Hiei. She extended one pinky out to him, waiting until he did the same and interlocked them for a moment, sealing the deal.

"I don't count you as a girl anyways,"

"Thanks a lot," Mukuro punched him in the arm.

"Ow!" He rubbed his arm, "I meant it in a good way!"

"Whatever… You know they're looking for you down there," She looked out to the scattered school children below.

"Like I care!"

"You'll get in trouble if you don't go back, and they find you here,"

"Let them come!"

"But if you have to pull a card again, then you can't play hide and seek at recess tomorrow!"

"So?"

"I was gonna show you my super secret hiding place…" Mukuro smirked a little. Hiei thought for a moment, Mukuro always won at hide and seek. He extended a pinky towards her.

"Deal,"

…

"Omigosh THERE you are Hiei!" Boton ran towards the small boy who was walking with Mukuro towards them.

"Where did you go!"

"Can't tell you, we pinky swore," Mukuro explained.

A/N: Ahhh don't you just miss those days? Preschool was so much fun! XD… Oh well… So what'd you think? I'm actually thinking about making a multi-chapter AU for HieixMukuro (not of one in preschool, that'd be dumb…) Lulz So tell me what you think!
