AN: Welcome! This is Part 1 of my Naruto series Will Of Fire! I'm only putting up the prologue until I've got several more chapters written, because I don't want to accidently get two chapters up and never update again! Authors who do that piss me off:) But anywho, if you like the sound of this, then you can check out my profile for more info and updates! Or just add this to your alerts and you'll be notified when I start updating. Enjoy! SR

"Kakashi-Sempai! I've done it!" A young voice yelled, running up to the silver haired boy. "I walked to the top of the tree!" Kakashi smiled and rubbed the top of her bright pink hair affectionately.

"Good job kiddo. Now I can teach you the next step." The four year olds eyes widened.

"YAY!" She screamed loudly, spinning in a circle with her arms outstretched. The Genin chuckled at her antics. "So what will I learn now!" She was wobbling slightly from all the spinning, her eyes unfocused.

"Once you get over your dizziness I'll show you." Kakashi was only six, but had been enrolled in the Academy at age four, and graduated that same year.

"Alright!" The pink haired girl bit her lower lip as she waited to the dizzy spell to pass. "I'm good now!" Kakashi snapped and visibly sent the chakra to his feet.

"It's the same basic concept, but it'll be a lot harder."

"Are you going to fly?" The young girl asked amazed.

"No." Kakashi chuckled again. "I'm walking on water." He stepped onto the slow river next to them and, with only a little trouble, made his way to the middle.

The girl excitedly pushed the chakra to her feet, and ran out onto the lake.

"Hamai!" Kakashi yelled, racing back to her. He reached down and managed to grab her before she completely slipped under water. He placed her back on the ground. "This is a lot harder then walking up a tree. The bark doesn't move underneath you, while the water does. You have to work on setting your chakra so that it's flexible enough to bend with the water."

"What does that mean?" The boy scratched the back of his head.

"I actually don't know, that's just what Minato-Sensei told me. But how I did it was by picturing the chakra at me feet as water itself, so that it could move like the water did, and hold me above it."

"Okay!" Hamai shouted. She closed her eyes, concentrating on her chakra for a moment, before stepping back onto the water. Kakashi watched impressed as she managed to stay standing for four seconds before slipping under. He quickly caught her again, so only her pants got wet.

They worked for three more hours, and by the end, Hamai and Kakashi were playing tag on the river, only having a few slips each. Wanting to challenge her more, Kakashi expanded their game to the hole clearing, so that Hamai would have to quickly change her chakra so she could run on the ground, up trees, and then across the water without pausing. Of course, this was also training for Kakashi, but he wouldn't admit that to the girl.

"Hey there! I thought I'd find you here." Minato Namikaze walked into the clearing, smiling as he saw Hamai chasing after Kakashi across the ground. The Jounin had no idea that his student was teaching his little sister everything he learned.

"Hey Minato-Sensei!" Kakashi yelled breathlessly.

"Hi big brother!" Hamai yelled, stumbling slightly. Kakashi decided to finally show off his teaching skills, and jumped against a tree to push off in the opposite direction. Minato about called out an unfair move when he saw Hamai copy him exactly.

"What the…?" Then Kakashi raced across the river and started climbing a tree over there. Hamai immediately followed after, completely terrifying her older brother. "Hamai don't run on the water! You'll… fall?" Hamai's foot only dipped slightly into the water from exhaustion, but otherwise she crossed just fine. He stared in shock as the kids passed back in front of him, Hamai finally tagging Kakashi. They fell down onto the ground breathing hard.

"Wasn't that cool!" Hamai shouted breathlessly at the blonde.

"What the hell! Kakashi have you been teaching Hamai behind my back?" The kids were shocked.

"Was I not supposed to?"

"She's two years younger than you!"

"She's the age I was when you started training me though. I just wanted her to have an edge over everyone else when she started at the Academy."

"She has three more years before Academy! She does not need to be running across water at age four! You're just now learning this! Why would you teach a four year old? She's not even supposed to be able to control her chakra at all yet! What the hell?" Minato continued ranting for at least an hour. He didn't stop until Hamai walked down the stairs of their house, now in dry clothes, and joined Kakashi on the couch. Minato stopped his pacing and took a deep breath. "Sorry… that just really scared me. You can continue teaching her if you want, you seem to have a knack for it. Just… just don't let me see any of the dangerous stuff."

"What part of being a ninja isn't dangerous?" Kakashi asked, throwing words Minato has once said back at him. Minato scratched his head and smiled.

"That's my point."

"So I can't show you how good I am with shurikin?"

"NO!"

"Creating paper bombs is probably out too, right?" Kakashi asked.

"Yes. Wait, what? I haven't even taught you that yet!"

"Just for future reference." The Genin grinned at the look of panic on his Sensei's face.

"On second thought, maybe I do want to know what all you're teaching her." The kids looked at each other quickly.

"Probably not." Minato hid his face in his hands.

"God help me."

"Don't worry big brother, I only burnt down three trees before Kakashi put it out!" They both started chuckling. Instead of more yelling like Kakashi expected, Minato flopped down onto the couch and groaned. Kakashi and Hamai merely laughed louder.
