Kamitari: Hey! This is Kamimura Kaoru's and my account o.O; We write obviously... BxK or KxK fics with this ^___^ Nyao! Anyway... I'll be doing the A/N for this chapter @.@ Eh... The name of this fic is 'Blood Stained Hearts' since this will be Angst and a Romance story. Kaoru is an assassin, along with Kenshin, in the Ishin Shishi! Whoa Oo; We were intrigued... how come women weren't in the war... eh... anyway... On with the story! Kaoru still uses the Kamiya Kasshin Ryuu... though for killing instead of protecting. We don't own Rurouni Kenshin although we wish we did o.o;

Blood Stained Hearts : Welcome to the Darkness

:: + ::

Blood. It was everywhere in Kyoto. It was the Bakumatsu. There was the sound of swords clashing, bodies falling, blood splattering... everywhere. No one was safe... not the men, not the children, not the women. All but one woman. She wasn't exactly who you considered safe but she could take care of herself... for she... was an assassin.

She was merciless. She had no heart. She was as cold as the coldest glacier in the world. She was the Kurai no Musume as she was dubbed by her fellow assassins in the Ishin Shishi, she was Darkness' Daughter. Her fighting style was the Kamiya Kasshin Ryuu, her father's style... but instead of using it to protect people, she was using it against them. Her raven hair was usually held up high in a ponytail so as not to distract her while she continued with her onslaught. Her sapphire blue eyes, always showing no emotion, her face, blank. No one could match her abilities... except one. His name... Battousai... her counter part, her adversary... her partner in the Ishin Shishi. Her name... Kamiya Kaoru... his name... Himura Kenshin.

"Finished already?" mumbled a voice from beneath the shadows, a pair of reddish eyes there as well.

The girl just shrugged as she mumbled, "Go away Ichiro... I don't want to talk to you." She then flung the remaining traces of blood of her katana. She loved to see the blood stain her sword... but she never let it stay there for long due to the fact that her sword might grow red in time.

"Why should I?" replied Ichiro as he finally showed himself in the light. Soon, he walked over towards her, his eyes, roaming around her petite body lustily. As he greedily tried to touch her, she kicked him in the shin as she muttered, "Asshole." Her blue eyes then left the sight of the wincing Ichiro as she walked towards an inn, her feet making no noise at all.

:: + ::

"Bah... too easy," thought Kenshin as he slashed through the bodies of members of the Shinsengumi. He was told to do this while Kaoru was told to kill another group in the eastern portion. He had hoped that the samurai coming from the opposing forces had been tougher than this... this was just too easy for him. Their skills were mediocre compared to his.

"Where the hell is Saitou when you need a good fight," thought Kenshin as he killed the last of the group. Flinging the blood of his sword, Kenshin looked down on the mess of bodies on the ground before heading back to the inn where they were staying. He was the last student of Seijuro Hiko. His fighting style, the Hiten Mitsurugi Ryuu.

As he walked along the dark path... he noticed... it was full of bodies, again, from the Shinsengumi and maybe a few civilians were there laying on the ground... dead. His amber eyes scanned the bodies... familiar slashes were on them. "Kamiya's work," he thought as he quickly brushed past them and entered the inn.

"Would you like some tea, Kamiya-san?" asked a brown haired girl... she was about ten or eleven, no younger. Kaoru looked at the timid girl before nodding her head. The girl nodded as she rushed to the kitchens to get a pot of tea and a glass for Kaoru. Kaoru sighed as she shifted from her position... it was getting uncomfortable just sitting down in the floor for the past thirty minutes or so. Kenshin still wasn't in the inn... until... the door opened anyway. Kenshin's familiar amber eyes and fiery red hair entered the room, everyone but Kaoru cringed at the site knowing that he could just kill them at any given point... either... he felt like it or he was ordered to do so. Most of the time, he killed because he was told to do so but at other times, he killed because he wanted to see blood. No one could contain him... except Kaoru. She was the only person who wasn't scared of facing him because... her abilities matched his perfectly, speed, quick thinking and abilities as a samurai.

"What took you so long," taunted Kaoru as she finally stood up, brushing off some dust which landed on her dark blue gi.

"Tch... it's like you care at all Kamiya," replied Kenshin emotionlessly.

"Took you thirty minutes later than usual... I think it is something that we should know... why you took longer than usual," replied Kaoru, pointing at the time.

"I wanted to see them suffer longer," replied Kenshin as he shot her a 'There-you-happy?' look. Kaoru nodded grimly as the girl from earlier walked over to her, a glass and the pot of tea. Kaoru took it and set them both on the table as the girl scurried off to get Kenshin another pot and glass who mouthed that he wanted one. He and Kaoru never killed any child or woman who was under the care of the Ishin Shishi but if the child or woman wasn't under the care of the Ishin Shishi, they killed them without any hesitation. Kaoru then walked off into the opposite direction as Kenshin sat down in the seat nearest him, waiting for the girl to come back with his tea.

The other samurai were gaping at the conversation of the two best assassins in the Ishin Shishi. They just glared daggers at each other, hands above the hilt of their own sword, as if threatening to kill the other right then and there. Just then, Katsura entered the room.

"Himura, Kamiya, come in here now," he barked out as he pointed towards a secluded room. Kaoru and Kenshin both shot him icy glares saying that they'll go, as soon as they finished their tea. Katsura couldn't take no for answer so he told them the only thing that could make them move, that they would be forced to work together on every damn mission if they didn't cooperate. With those words coming out of Katsura's mouth, Kaoru and Kenshin stood up from their chairs and walked towards the room. They soon reached and tried to push the other out seeing that he/she wanted to enter it first.

"Damn it get out of my way," growled Kaoru menacingly as she eyed him.

"You get out of the way," growled Kenshin in reply as his hand roamed around in order to find the hilt of his sword.

"Let Kaoru pass first, Himura. Ladies first," commanded Katsura. Kenshin unwillingly obeyed as Kaoru shot him a triumphant look.

"Is she even a lady? She's an assassin... like me, but still worse" thought Kenshin as he entered the room after Kaoru.

"What do you want," mumbled Kenshin as he lay back on a wall, his eyes closed.

"Well... you both are being assigned to protect a certain man in order to get to Tokyo. He has to go there since he has a lot of work to do there. You both will be his body guards until he arrives in Tokyo, there, you can leave him in the hands of the other Ishin Shishi guards which are standing by for his arrival," informed Katsura as he set a map down, showing the path they had to take.

"Nani?! You said you wouldn't pair us up in any mission if we followed you earlier," growled Kaoru as she slammed her fist on the table.

Katsura sighed as he said, "Well, it's not my decision. It's only when _I_ am in charge of the mission and I'll be needing either one of you to be in it, that's when you WON'T be partnered. This was Shao's idea... not mine." Kenshin glared at him. Of all people... why her? It would've been better if he had been partnered with the blunder of an assassin, Ichiro.

"Fine," growled Kenshin as his eyes turned into a familiar shade of amber, "When do we leave with whoever we have to protect?"

"Tomorrow, at dawn," replied Katsura. "The name of the official is Taniru Tomoshi."

"Isn't he the man wanted by the Shinsengumi?" asked Kaoru upon hearing the name.

"Aa, that's why you both were assigned to protecting him," replied Katsura as he stood up from his seat, "That gives you tonight and early morning to pack whatever you need, shine your swords and all other preparations that you need to do." Kaoru and Kenshin simply nodded as they rose to leave the room. Kenshin grumbled at the fact that he had to let Kaoru walk out of the room first because she was a girl... she was no ordinary girl though.

"So, what happened in there?" asked a male voice as Kaoru walked out of the room. As she sat down, she glared at him with an ice cold look that could freeze anything.

Kaoru then raised her head as she said, "Yui, get me a glass and a pot of tea." The brown haired girl from earlier nodded her head as she scurried off to get what Kaoru asked for. Kenshin soon emerged from the room and walked quickly towards a wall where he would probably lean on until a hand wrapped firmly around his wrist.

: ~ : Kenshin's POV : ~ :

As the hand wrapped firmly around my wrist, my eyes turned a slight amber color and I turned my head around to see to whom it belonged to. Seeing a familiar black-haired girl with gray eyes, I muttered, "Get your hand off me Chidori-san." She looked at me and shook her head.

"No, I won't. I have your wounds to heal," she replied.

"How about Kamiya's... how about her wounds... why tend to mine first..." I spat as he shrugged her hand off of my wrist.

"I don't know... It's more fun to treat yours," she replied with a teasing tone. Not that she really liked him or anything but it was fun to annoy him... up to a certain extent.

"I could just kill you right now Ameyama Chidori," I growled as my hand grasped the hilt of a sword. Ameyama shook her head in fear as she walked over towards Kamiya in order to treat the wounds she received from earlier's venture. I shrugged and walked off towards the wall where eyes looked at me.

"What?" I growled as I finally broke the silence.

"What did Katsura tell you both earlier?" asked Ichiro. He wanted to become a top assassin, like me, I just don't see it in him to be like me.

"We're being assigned to guard Taniru for his trip to Kyoto," mumbled Kenshin as his eyes turned to that familiar shade of amber once more.

"Can I go with you?" asked Ichiro with a slight hint of hope in his voice as he wanted to see the two of us kill and slaughter people with our own hands. I sighed and looked at Kamiya. I saw her have a grim look on her face, saying no. Not that we agree on things very often but this time, Ichiro was too clumsy. We couldn't afford for Taniru to die because of one being.

"No, you can't come with us Ichiro. We're not supposed to let you go with us," I replied. That was partially lying since Katsura said we could take anyone else with us. Kaoru didn't hear that but I'd tell her later... when the time comes. Ichiro growled as he slumped down on the floor, across from me sensing I was still agitated by his earlier question... if he could tag along.

: ~ : Normal POV : ~ :

"Are you done yet?" asked Kaoru impatiently as Ameyama finished bandaging her right forearm.

"Almost. Be patient Kamiya-san," replied Ameyama as she applied some medicine to wounds on her other forearm. Kaoru winced a little due to the fact that the medicine stung a little. Kaoru sighed as she fixed the swords on her left.

"Done," announced Ameyama as she stood up straight, wiping away beads of sweat from her forehead. Kaoru then stood up as she walked towards another chamber, where the stairs were found in order to get to her room. She had finished her tea while her wounds were being tended too.

"Kuso! Why do I have to be partnered with him?!" cursed Kaoru mentally as she climbed to stairs to her room. She had only one thing to pack with her... an extra set of clothes. Kaoru walked towards her room when Ichiro appeared... again.

"What do I have to do to get you out of my life, Ichiro?" growled Kaoru as she walked along the hall.

"Nothing... because I want you," replied Ichiro as he eyed her lustily. Kaoru groaned mentally as she kicked him in the stomach, causing him to curl up on the floor, trying to catch his breath.

"You should learn that I will never learn to love an asshole like you," mumbled Kaoru as she entered her room in order to get a dark blue gi and a hakama out and packed into an extremely small bag. Soon, Kaoru was sitting down on her bed, thinking of things like why she was in the Ishin Shishi and why she disobeyed her father's wishes.

: ~ : Flashback; Kaoru's POV : ~ :

"Tou-san! Where are you?" I shouted as I ran through the dojo. My father was a sensei of kendo, his style, the Kamiya Kasshin Style. He taught it to me when I was young, I was thirteen at the time. My father was in the dojo, looking at the wooden plaques hanging on the wall.

"Yes Kaoru?" my father replied as he turned to face me.

"Will you join the war?" I asked timidly as the wind blew.

My father shook his head. "And neither will you," he said finally as he grasped my shoulders, "I don't want to lose you." I smiled a little and nodded. Soon, I was told to go outside and help my mother cook food.

"Kaa-san! Why won't father join the war?" I asked as I helped her wash some radishes.

My mother looked at me with her blue eyes and said, "He sees no point in joining it. He'll be fine here." I nodded grimly as the thought of joining the war appealed to me. I had mastered all the moves of the Kamiya Kasshin Ryuu even up to the succession technique. I was as good at wielding a bokken, shinai and a sword as my father at this young age of thirteen. I was also gifted with a god-like speed. Soon, my mother was cooking the food and she told me to go out and do the other things I wanted before it was dinner. The war had been going on for a few months now and I see bloodshed on the streets everyday. I heard that the man who was responsible for this was called 'Battousai' due to the fact that he had mastered all the invented Battou Jutsu techniques. I also head that his sword style was unheard of, that only few people are ever able to master it. I soon walked out towards the well.

Should I join it or not? Why am I debating on this, tou-san said I shouldn't so I won't. But... I don't feel complete here... as if I want to kill people on my own... as if my heart yearns for bloodshed caused by my own hands... for me to stain my hands with the scent of human blood. Anyway, I heard the Restoration is doing this for the good of the majority. Mou... but they'll never accept me... I'm a girl... a young girl. But it never hurts to try to join it right? But what about tou-san and kaa-san? I should tell them later tonight... after dinner... I don't care anymore if they'll get mad at me or not... this is what I believe in.

"Kaoru, its dinner time," called out my mother as she poked her head out of the dining area. I nodded happily as I ran towards them... possibly this being the last time I'll be eating with them as a family... before their anger pours out on me because of my decision.

After dinner, I set down my chopsticks and said, "I have something to tell you both." My face darkened as the time drew near for me to reveal my decision.

"What is it Kaoru?" said my father with a kind face. It broke my heart to tell them this but I needed to. This question has been bothering me since the beginning of the war.

"I... I... I'm going to join the war... with the Ishin Shishi," I blurted after a few moments silence. With those words, my father... from his kind and demure state... he became angry and violent.

"Nani?! Kaoru! I told you that you wouldn't!" my father spat angrily.

I stood up in order to face him. "I know! But this is what I believe in! You can't force me to believe in something else!" I argued in return.

"You will NOT join the war, Kaoru," my father said angrily as he grasped my wrist so tightly that it hurt. I shook my father's hand off and ran out the door as I heard my mother call out, "Kaoru! Kaoru!" Their words had fallen on deaf ears, I had ignored them. Running to my room, I changed into a dark blue gi and a pair of white hakama, I put two swords on the left side, those two swords used to be my father's but he had stopped using them. Tying my hair into a pony tail, I ran out the streets in order to join the Ishin Shishi.

When I arrived there and asked if I could join them as an assassin, they surprisingly accepted me. They somehow knew I had slashed my way through the path. I had killed over ten skilled warriors... warriors who were much older than me and supposedly better than me. A red-haired youth approached me, his eyes, an amber color. I shivered in fear. I realized who he was.

"You?! You're Battousai?! But... you're not much older than me. I had heard Battousai was near his thirties," I blurted out as I realized who the boy was.

"That's what most people think Kamiya-san. Most people don't realize I'm just a youth... like you... because I kill all witnesses before they can say who I really am," he replied coldly.

"Aa. Ano... My name is Kamiya Kaoru, you are?" I said.

"Himura Kenshin if you must know. Now, I will leave you for your training as an assassin Kamiya-san. I have much more work to do. I'll be seeing you around," replied Kenshin as he turned his back on me, his black gi slightly crumpled. I nodded as I turned to face the man who would train me.

A few months had passed and I became the second best assassin... second because Kenshin was still better than me. During those months, Kenshin grew to hate me because I was going to be as good as he. I grew to hate him because he was always so cold and arrogant when I tried to spark up a conversation... then again... assassins are usually like that. About a month later, it was proclaimed that Kenshin and I had the exact same skills as an assassin... it was that fateful day that it was also proclaimed... silently though... that we were rivals.

: ~ : End of Flashback; Normal POV : ~ :

"So that's why I left home," thought Kaoru as she lay on her bed to sleep. All assassins were extremely light sleepers so any sound made they could hear it and they woke up to either kill the spy or to talk to whoever needs to talk to them.
