Sakura's POV

It's only been a few months since Sasuke and I have arrived here, and I guess what would be suspected, everything was falling into a routine. I'd wake up, eat a small breakfast, train with Kabuto-shishou for countless hours, take a small lunch break, train some more, eat dinner, and then go to bed. It was all really dull to say the least.

I woke up, shifted my position, and nearly face dived onto the ground. Guess I was sleeping a bit to close to the edge. I threw the thin covers off my body and threw on some clothes. My normal attire had changed now that I was in the sound. It now consisted of a black tee shirt with some wire mesh covering it. A pair of dark blue shorts, covered my legs just above my knees, fastened by my new Oto headband. Bandages covered the rest of my legs, all the way to my black sandals. Wrapping it all up was a pair of grey gloves that shishou got me. They would allow me to channel my chakra better. I had come to realize that black colors are more useful then pink or red.

I walked out of the stuffy black room and continued down the corridor. I made my way to the cafeteria only to find it relatively empty. That itself was strange, because it was usually crowed with other Oto Nin. I shrugged it off, I was probably early or something, and got some food. Steamed rice and miso soup. Yum.

I took a seat in one of the tables and began to dig in. Halfway through the meal, I heard footsteps, causing me to look up. It was Sasuke. I watched as he got some food and walked over to me. He hit the seat with a thud and raised an eyebrow.

"You're up early."

I scratched the back of my head, "Yeah, I know."

He didn't say anything, but continued to eat. His outfit too had changed, though I couldn't say it was exactly better. It was a white robe left open in the front with a purple rope wrapped around his waist. Pretty simple, though lacking in the fashion department.

I tried to start a conversation, but as usual, all I got were monotonous replies. It didn't really matter anymore, because I was now fluent in "Sasuke Speak."

I had finished my meal, but decided to wait up for him. I didn't have to wait long as he too was finished with his meal. We both stood up from the table and placed our plates in the sink. We walked down the maze of a base, and soon arrived at my work place. I thanked Sasuke for walking with me, and entered the room.

Like most rooms in the base, it was a black colored room with nothing really special about it. There was a simple bed and a bunch of medical tools in various cabinets. I took a seat in the chair in the corner and waited for Kabuto to arrive.

After five or so minutes had passed, he walked in. I stood up and gave a bow while he walked over to the bed.

"Now, Sakura. I have a new ninjutsu for you." Kabuto motioned to the door. "Come in!"

An elderly man walked into the room. His face revealed he was frightened as he stumbled onto the bed.

"Now, what I am going to teach you is a killing technique. It takes a few seconds, and if you have your enemy on the ground or close to your hand, this is perfect. It is also good for assassination, if you don't want to leave a mess."

My heart nearly stopped. A killing ninjutsu? I never even killed anyone before, much less an elderly old man! I tried to hide my nervousness as I walked over to the man.

Kabuto continued, "Now, its called 'Higi: Kibaku Shinzou', or Exploding Heart technique. I want you to channel your chakra over his heart, and sever everything surrounding his heart. It should take you only a few seconds."

I nodded, looking more confident then I felt. My hands were involuntary shaking as they covered the man's heart. I closed my eyes as I began to concentrate around severing everything connecting to the man's heart. It was harder then I thought. After a minute or so, it was done, and the man lay dead.

Kabuto frowned in dissatisfaction. "Sakura, that took you way to long. Remember, only a few seconds should be applied in this! Now, try again!"

He moved the body, and then he clapped his hands, and this time a young boy walked in. My blood ran cold. I couldn't possibly do this. An old man was at least near the point of death anyway, but this was a young boy! I took a deep breath to calm myself as the young boy walked over and laid down on the bed. I could feel myself become clammy.

"Um, shishou, can't we try on an elderly man again?" I noticed a frown forming.

"No. You are an Oto Nin, and this means you must kill anyone you are ordered to, no exceptions. Now, try again."

I wanted to run away, but this was the path I had chosen. To be with Sasuke meant that I must do what they told me. I placed my hands over the small child's heart, and repeated the process. However, again, I had failed.

"Again!"

As I sat down to lunch my mind felt blank and numb. My emotions seemed to have run away into thin air. I looked down at my lunch, steamed rice and some meat. I didn't take a bite, because I knew that if I did, I would hurl. I knew that when I returned to Shishou, he would force me to continue to practice that technique until it was perfect. He always did that.

"What's with you?"

My head shot up. I was so spaced out that I didn't even realize that Sasuke had sat down. I forced a grin and shook my head. "Nothing's wrong! I must have eaten something that didn't agree with me!"

Sasuke said nothing, but stared at me. I shifted uncomfortably as I took a bite of my food. I wanted to spit it out, but then Sasuke would know something was wrong. However, when he looked away, I spit the food in a napkin, disgusted.

I continued to fake eat until the plate was cleared. I had a feeling that Sasuke knew what I was doing, but if he did, he didn't say anything. When we were done, we placed our plates in the sink and went our separate ways.

What I didn't notice was that Sasuke had a sword attached to his back. If I did, then I would have realized that Sasuke had killed someone, because I knew that Orochimaru even stated he would give him one if he did. But I never noticed.

After I finished walking, I arrived at the door. My hand was on the door's handle, but my body refused to enter. Before this encounter, Kabuto had only been teaching me healing techniques, so this was a huge change. I vaguely wondered if he was going to teach me more killing techniques after this one, but I knew the answer was yes.

I steeled my self and entered the room. Kabuto was already waiting.

I had skipped dinner that night. I just couldn't eat, and just the sight of food now had made me want to gag. I collapsed onto my bed and just laid there. I didn't think, didn't move, I just laid there. Then almost spontaneously, tears burst forth from my eyes. In the academy in Konoha, they had given us a counselor on how to handle these things. Still, it didn't make it easier.

I heard knocking on my door, but I ignored it. After a few minutes, the knocking stopped. I heard footsteps walk down the hall and I vaguely wondered if that was Sasuke, but I knew it wasn't. He wouldn't come after something as trivial was this.

I closed my eyes and began to think. This would have happened sooner or later, right? That was what being a ninja was all about. The thought comforted me yet I still felt numb. I forced my self into a dreamless sleep, hoping that tomorrow won't be as bad.

Whoot, done! Hope you enjoy! Next chapter will be a time skip chapter. I just wanted everyone to see Sakura evolve into a killer. She had to face it one day, and how else would be sadistic enough to help her D

Anyway, hope you enjoyed!
