"Well then." Vader began, turning to the now thirteen year old Tsubaki. She was slender and fit, with enough muscle on her so she didn't look weak, but at the same time, not enought to say that she was jacked, either. Her developing breasts was protruding slightly out of her chest, and her curves were at the very early stages of development. Her black jumpsuit was tight against her body and her blonde hair was in a medium length ponytail hanging over her left shoulder. Her bright blue eyes were very intense, but still held a glimmer of child like curiousity.
In the 8 years that he knew her, Vader had found her to be someone he had to watch out for. Many times she would prank him for no good reason, using the force to appear invisible, and then as soon as he turned the corner into her view, she would sneak behind him, grab his shoulders and shout, returning to visibility. On top of that, she had managed to find a way to mimic creepy noises to wind him up, setting his guards on edge as well. She was quite the handful.
Despite that, she was a cheerful presence aboard the Death Star. She would visit the wounded in sick bay and tell them elaborate stories that she would think of on the fly. On one occasion, Vader himself had gone to sick bay to repair his portable resporator, and had to be hooked up to a larger machine in the mean time. She had visited him and told him a story about a princess that had been transformed into a dragon because of a prince's cold blooded murder of a dragon chick. It was one of his fondest memories to date, and was the reason why he didn't stop her from continuing the hobby.
"Lord Vader, Would you say my training is complete?" She asked.
"Far from it young one. I have yet to train you in the ways of the Dark Side of the Force." He said calmly. Though he was anything but calm. His heart was pounding. He would finally get to see how skilled she was with the force beyond her silly pranks. "For now, we shall have a duel using only the force. Nothing that can kill, unless you purposefully miss. Understand?"
"Yes sir." She said standing.
"Ready? Go!" Vader started with a Hand filled with lightning, aiming to brush her side. She quickly turned invisible and drop kicked him from behind, sending him to the ground. He quickly checked his resporator and deemed it fine to continue, and swung his body, turning to the left just as Tsukbaki Force Pushed the ground where he was previously. There was a sharp crack, and Vader called out in agony. His arm had gotten caught in the Force Push and the bone had snapped. Tsubaki stopped as her teacher made pained moans and panted slightly.
"Master, I'm sorry...!"
"Izfine..." He wheezed out. "Ohhhh... You seem to have... Nnghh... To have mastered the Light Side... Just as Dr. Colrez said..." He said, attempting to get up. Tsubaki halped him and accidentally tapped his arm, making him double over it and growl.
"I'm so so sorry...!"
"Just get me to sick bay..."
"Yes sir..."
