Enter! Josephine Yukikaze!

"Today we're going to learn...." They carried on that day training vigorously and tirelessly. Months went by and Josephine made a large amount of progress. She was faster, stronger, smarter, and had much more endurance. Even her chakra levels had increased. Now at the 6 month marked Zakku was out at the Lake with Josephine. "Today we're going to try controlling your Blizzard Jutsu. It seemed like when you used it on me, it went everywhere and that could turn out bad if you have teamates."

Josephine pouted, she never worked with teammates on missions. And if she did, they usually died in battle.
"Erm, okay. Finally we get to work on my blizzard jutsu!" she said putting her fist in the air, "yeah!"

Zakku went a good 100 yards from Josephine and summoned the large tree from day 1. He went bac and pointed at it. "Try to hit only the tree." Zakku said as he stood back ready to defend against the blizzard.

Josephine smirked and prepared the handsign for the blizzard jutsu.
"Fuyuki sparkling wind no jutsu! (キラキラ冬樹雪風)"
A snowstorm whipped up, Josephine tried to concentrate the energy on the tree, but the wind kept going in different directions, she was so used to having it going crazy everywhere. It was hard to control the raging winds.
"Fuyuki sparkling wind no jutsu! キラキラ冬樹雪風!" She said again concentrating harder, her chakra flow started to speed up and so did the wind. The entire area, not just the tree, got covered in frost.

Zakku saw a whip of the blizzard headed at him and used his black chakra to block the attack. He slid back a bit. "Okay try again... Don't worry about me, i can defend myself." He smiled and waited defending himself from the wild attack

The girl sighed and tried again. This time, slowing the wind down so she could control it.
The winds started to speed up again, with more control, she was finally doing it. Finally controlling her winds!

"There you go, keep it up!" Zakku watched as she gained control over her jutsu. It was astonishing how fast she progressed. He watied to see the outcome.

Josephine's chakra flow started to speed up. Her eyes glowed light blue due to her status of using a clan jutsu, she can open her eyes in the intensely bright snow and not get blind by the flurry.
With a final sharp yell, she released the jutsu, which caused the snowstorm to come into one giant snowball and explode. Sharpened snow flying everywhere
