Hello everybody, TravyMcNavy184 with another new story. This one will be a High School DxD standalone story, my first one since my Bloodrayne story. In this story, it will follow Issei and the ORC as well as my OC, who is Issei's older twin sister Isane. I have read a lot of fanfiction where Issei has a brother but there are very few where he has a sister that I have found. As far as pairings go, I haven't decided who Isane will end up with, I'm making her so that she is too focused on her studies and her own thing to worry too much about relationships, but we'll see where the story takes us. So read and review, nothing too mean please and let me know what you think. Anyway hope you enjoy it. As always, I own nothing but the Ocs.

Appearance: Kiyone is a tomboyish young woman with a curvaceous figure and moderately muscular build along with brown hair that extends to the middle of her back, which she keeps tied in a high ponytail tied with a black ribbon and brown eyes. She is usually seen wearing the basic Kuoh Academy's girl's uniform. When exercising she wears various colored tank tops with black sweat pants. When in battle or on the job, she wears modified soldier's fatigues with combat boots which are black in color, a gift she received from Azazel when she left to return to Japan and keeps her hair in a low pony tail. She also wears a black skull mask to mask her identity as an assassin, earning her the moniker the Black Skull. As a child, Kiyone had shorter hair and wore various dresses with flowers on them.

Personality: Despite being twins, Kiyone is the exact polar opposite of Issei, leaving many people to find it hard to believe that they are related. Kiyone is a rather serious individual who has very little time for other people's shenanigans, especially her younger twin brother's and his friends. She easily gets sidetracked due to Issei's personality clash and can turn rather dark if pushed far enough, which scares other people, including her family. Underneath her cold and serious demeanor however, Kiyone is a kind individual who is fiercely loyal to those who earn her trust and respect and despite their differences, Kiyone loves her brother dearly and would do anything to protect him. Kiyone is also a huge gun enthusiast, having near encyclopedic knowledge about various firearms which stemmed from books, the internet, and training from her Blackwater instructor. When on the job or during a fight, Kiyone is calm and composed and thinks carefully in the situation she is in. As a child, Kiyone was more shy and introverted, keeping mainly to herself and only ever opening up to Issei.

History: Before Kiyone and Issei were born, their parents had trouble trying to get pregnant, having failed twice due to miscarriages. After their mother got pregnant again, their father paced back and forth in front of a Shinto shrine honestly wishing that they were successful. When the time came for them to be born, they were ecstatic to learn that they were blessed with twin children. The girl being born first, was named Kiyone since their mother always wanted a daughter named Kiyone while the boy, born seven minutes later, was named Issei. She and her brother attended the same middle school as Matsuda and Motohama. During middle school, Kiyone gained an interest in firearms from watching various action movies, anime, and manga. Before starting her first year at Kuoh Academy, she was invited to the United States to learn more about guns from an instructor at the PMC Blackwater, who turned out to be Azazel. During a training exercise gone wrong, Kiyone was seriously injured and was close to death. To save her, Azazel reincarnated her into a fallen angel using an unknown method.

Powers and Abilities

Light-based Weapons: Being a fallen angel, Kiyone is able to form weapons made from light with ease. While she can create light spears, Kiyone mainly uses her light manipulation powers to create bullets made from light.

Master Marksman: Kiyone is an incredible marksman, capable of shooting targets with remarkable accuracy and capable of feats such as firing behind her back without looking behind her. She prefers mid to long range combat, with a specialty in sniping. She also dual wields pistols, her favorites being dual Jericho 941 pistols which she wields with incredible skill. While she specializes in long range combat, should the need arise she can use close range weapons as well like shotguns. Her favorite sniper rifles are the Mosin Nagant M91 used by her idol, Aliya Moldagulova, and the PGM Hecate II anti materiel rifle.

Expert Hand to Hand Combatant: While she prefers to use firearms, Kiyone is very well versed in unarmed combat. She is capable of holding her own in fist fight with garden variety thugs as well as middle class level Devils.

Enhanced Durability: While not as durable as her brother, Kiyone can take a tremendous amount of pain, ranging from knife slashes to magic attacks. She even suffered a broken arm and still managed to fire her rifle.

Immense Stamina: At first Kiyone possessed average stamina as a child, but after her training at Blackwater and doing her morning training regiment, her stamina has increased exponentially. After becoming a fallen angel, her stamina increased even further capable of carrying her sniper rifle and pistols as well as clips of ammo great distances without rest.

Flight: Being a fallen angel, Kiyone can use her four fallen angel wings to fly.

Equipment

Infinite Armory: Kiyone's artificial sacred gear given to her by Azazel, which grants her the ability to create firearms of any size, type and variety. She is even capable of summoning weapons from past eras, such as flintlock pistols. All she needs to do is think the weapon in her mind and have a clear vision of it and it will appear in her hands.

Prologue

The sun was shining on another weekday in Kuoh Town. The sun filling the darkness of a particular bedroom in a familiar two story house. The room had posters of various FPS games as well as some family photos. On the desk was a high end gaming desktop with several books on firearms and firearm maintenance. There was a bookshelf with similar books as on the desk. There were even a pair of Jericho 941 pistols and a couple assault rifle airsoft guns hanging on the wall. A few moments later, the occupant's alarm clock went off.

"Goooooood morning Kuoh Town. It is now half past the hour of 5am in the charming little city. Today's weather will be partly cloudy with a 15 percent chance of rain with temperatures in the mid fifties today and in the low thirties starting tonight so bundle up if you find yourself out and about tonight. Coming up in-" The person on the radio was silenced as the occupant of the room pressed the button to turn it off while rubbing her eyes to get the sleep out of them. The occupant was a teenage girl of about 17 with brown hair that went down to the middle of her back and brown eyes. She had a rather curvaceous and moderately toned figure with large breasts. She wore a black tanktop with white panties. This girl was Kiyone Hyoudou, oldest daughter of the Hyoudou family and older twin sister of Issei Hyoudou.

Kiyone stretched her arms to get the starch out her joints to help wake her up. She stood up and faced the door to her room. She then dropped to the ground and began doing push-ups. After reaching fifty pushups, she got on her back and did the same amount in sit ups. After doing her sit-ups, she did the same amount in squats. After doing her squats, she put on a pair of black sweat pants and proceeded downstairs to the front door of her house. She grabbed her house keys and proceeded to run five laps around the block.

After the fifth lap, it was now 6:30 so she went back inside her house to shower and get ready for school. Walking inside, Kiyone saw her mother in the kitchen making breakfast and her father sitting at the table reading a newspaper. They saw their daughter walk in the house and smiled at her with pride. "Good morning Kiyone." Mrs. Hyoudou greeted the older Hyoudou twin.

"Morning mom." Kiyone greeted back.

"Back from your morning workout pumpkin?" Asked Mr. Hyoudou as Kiyone wiped some sweat from her forehead.

"Yeah, gotta stay in shape after all." Kiyone responded to her father.

Both parents smiled at their daughter. "It's amazing how you rigorously work out early in the morning yet still manage to have energy for school. You're even the top of your class. You make us both so proud" Said Mrs. Hyoudou as she continued cooking breakfast for her family.

Kiyone just smiled at her parents as she headed upstairs. "I'll be in the shower."

"Kiyone." Mrs. Hyoudou called out. "Could you wake your brother up before you get in the shower." Kiyone just groaned at the request. She didn't have the time or motivation to deal with her brother's antics. "Yeah sure." She said unenthusiastically. She then walked to the door next to hers and knocked on the door. "Issei, are you up?" She asked not getting a response. She knocked again and asked the same question, again no response.

Knowing she didn't have time for this, she turned the knob and entered her brother's room. The walls of the room were littered with posters adorned with images of half naked women or women with barely any clothing on them at all. Seeing the posters made Kiyone feel very uncomfortable. She knew her brother was a pervert but it still creeped her out to be in his room. In the bed still fast asleep was a boy around Isane's age and bore a similar physical appearance to her but the difference was the boy had shorter hair and it was spikier. This was Issei Hyoudou, the youngest child of the Hyoudou family and Kiyone's younger twin brother.

The story goes that Mr. and Mrs Hyoudou had trouble having children, having had two miscarriages back to back. When Mrs. Hyoudou got pregnant a third time, Mr. Hyoudou paced in front of a shinto shrine repeatedly and prayed that they would be successful in having children this time. His prayers was answered as when their children were born, they were more than ecstatic when they were blessed with twin children; a girl born first and a boy born seven minutes later. Mrs. Hyoudou always wanted a daughter to be named Kiyone. When the boy was born, they named him Issei.

Kiyone just looked at her brother with an annoyed look on her face. She shook her brother to try and wake him up. "Issei, come on it's time to wake up."

Issei just ignored his sister and continued dreaming his own dream with a goofy grin on his face. "Mmmm...breasts. Heeeeeeeeh." He mumbled in his sleep. Kiyone was further annoyed at this. She didn't have time for this but she knew there was one thing that wouldn't fail. She shut the door to her brother's room, approached her brother's ear and whispered in his ears. "Issei, there's a really pretty girl downstairs who isn't wearing a bra and whose titties are bouncing up and down and she's begging for a big strong man to come down and fondle them." She backed up and mentally counted down from three and then...

"TITTIES! YAHOOO-" Issei shouted as he shot out of his bed and jumped towards the doorway, only to end up face first into his door. He was then on his knees holding his injured face. He then looked up to see the smirk on his sister's face. Issei just glared at her, angry that she not only tricked him, but also because he fell for the same trick. "There are no titties downstairs, are there Kiyone?" He asked with anger in his voice.

Kiyone just shook her head. "What do you think you perv?" She asked sarcastically.

"Why do you always have to get my hopes up and then smash them?"

"It's not my fault you keep falling for the same trick Issei. Now get dressed and go downstairs and eat or we'll be late." She answered her brother, who just shot a glare at her. Kiyone then exited her brother's room and went to hers. She grabbed her school uniform from her closet and a clean bra and pair of panties from her dresser. She grabbed a towel from the hall closet and went to the bathroom to take a shower.

After taking a shower and getting dressed and put her hair up in a low pony tail with a black bow, she went downstairs to eat with her family, Issei having finished getting dressed and sitting at the table. After breakfast, Issei and Kiyone grabbed their school bags and bentos and exited the house to go to school. "We're off mom and dad. See you later." Issei called out.

"Have a nice day at school you two." Shouted Mr. Hyoudou as both he and his wife waved goodbye to their children. While walking to school, the twins were intercepted by two of their classmates. Two whom Kiyone wanted nothing more than to avoid if at all possible. One of them was a taller boy with a shaved head and the other was a boy a with brown hair wearing glasses. This was Matsuda and Motohama respectively, two of Issei's best friends since middle school.. What Kiyone didn't like about these two is the fact that they were bigger perverts than her brother. In fact, together the three make up 'The Perverted Trio', three of the biggest perverts in Kuoh Academy. Kiyone tolerated her brother's perverted nature and that was enough for her, she certainly need to be affiliated with two more.

"Yo Issei, my man what's up?" Matsuda greeted his friend as they bumped fists.

"Did you manage to watch the DVD we lent you?" Asked Motohama.

"Hey guys, yeah I did it was amaaaazing." Issei said with a lecherous grin, causing Kiyone to look at them in disgust. "Well that explains why you had a long night." The older twin said.

"Well hello there, Kiyone. You look lovely as ever." Motohama complimented the girl, who just shrugged off the comment. The last thing she needed was a compliment from a pervert. "Aww why are you so cruel Kiyone?" Motohama retorted all the while gazing at her body to figure her measurements. When Kiyone caught on what he was doing, she bopped him in the nose, causing a nosebleed.

"Try to figure my measurements again you creep, there won't be a surgery possible that will repair your eyes." She said with a rather wicked and sadistic voice, she was even covered in a menacing aura for emphasis, scaring the two other boys. "Damn Kiyone, you didn't have to knock him down like that." Issei said to his sister.

"Well he knows how much I find that little "trick" of his disgusting" Kiyone responded.

"Aw come on is it a crime to admire such a beautiful lady like you?" Asked Matsuda.

"A compliment coming from pervs like you, yeah it should be."

"Aw come on sis, you know you love us." Issei said.

Kiyone just looked at her brother with a disinterested look on her face. "Them I don't really care about. You however, I tolerate you." Kiyone responded, causing Issei to feel like a knife went through his heart.

"Oh, dear sister, your cruel words pierce my heart." Issei said in a dramatic tone, which Kiyone just rolled her eyes. Kiyione then looked to see the clock tower a ways away and looked at the time. It was now 10 minutes til eight. Seeing the time, now Kiyone was freaking out. "Oh crap, it's almost eight o'clock! We're gonna be late!"

The perverted trio shared in Kiyone's anxiety and immediately they all took off in a sprint towards school. They all knew that if they were late, they would catch hell from the student council president. While they were running, they didn't notice a man coming out of hiding from a corner wall. It was a tall man in his twenties with an average build with black hair, golden bangs and a black goatee. He was also wearing a gray yukata with a lazy smile on his face. He looked to see the kids running to school and couldn't help but chuckle. "Ahhh, the wonders of youth." He said. His eyes then fell on the younger Hyoudou twin, then his expression turned serious. "Kiyone, I hope you are ready for the events to come. When all is said and done, can you still protect your brother?"

After school

It was finally the end of the day and the students of Kuoh Academy were mingling with each other or heading to their after school club activities. Kiyone was sitting on the fountain by the entrance, a text book in her hands and a notebook by her side. She was finishing some of her homework while she was waiting for someone. As she was writing, she heard a voice calling for her. "Kiyone." She looked and saw a beautiful girl with shoulder length reddish brown hair and brown eyes which had swept bangs and a single strand of hair sticking from the top. This girl was Tomoe Meguri, a fellow second year student and a secretary fro the student council.

Tomoe was meeting Kiyone for tutoring lessons. Tomoe wasn't doing so well in her history class and since she and Kiyone had the same history class, Tomoe asked her for tutoring. Since Kiyone considered Tomoe a friend, she happily agreed to help her out. "Hey there Tomoe." Kiyone greeted her classmate.

"Hey, sorry if I'm late. Did I keep you waiting long?"

"Oh no don't even worry about it, I did some of my homework to kill some time. So, you ready for your session?"

Tomoe happily nodded her head. "You bet, thanks again for these tutoring lessons. If the president found out I wasn't doing well in one of my classes, I catch major hell." She replied.

As they were about to head to Tomoe's home, Kiyone caught the sight of a certain familiar trip of perverts walking across the courtyard. "What are those morons up to?" Kiyone asked out loud. She then looked to the opposite end of where they were walking and realized they were heading for the changing rooms of the Kendo club, whom she was sure were just about to get ready for club activities. She then scowled at her brother and her friends as she realized what they were up to. Tomoe looked at Kiyone with a confused expression.

"Hey Tomoe can you wait for a moment, I have to do something real quick?"

Tomoe looked at where Kiyone was looking and understood why she asked. "Going to go save that pervy monkey you call your brother again?"

Kiyone let out a loud sigh before she replied. "Unfortunately yes."

"Go on, I can wait." Tomoe replied. Kiyone smiled and then walked towards the changing room.

After a few minutes of peeping on the girls, the trio were eventually discovered and suddenly Matsuda and Motohama bailed, leaving Issei to take the brunt of the Kendo clubs wrath. Issei was now on the ground looking up to see the girls in their kendo uniforms and all holding shinai, ready to beat the pervert to a bloody pulp.

"Wait...please...don't hurt me." Issei begged sweating bullets.

"Why am I not surprised?" A voice itself known. Everyone looked to see Kiyone standing a few feet away from Issei and the Kendo club. Issei looked relieved to see his big sister.

"Kiyone, didn't expect to see you." One of the Kendo club members, the one with long brown hair said.

"Hello Muriyama. I'm here because I was waiting for a friend so I could help her with one of her classes." Kiyone responded.

"Oh really, are you not here to save your letch of a brother?" Another member, one with short pink hair asked."

"Why would I Katase, it seems to me that Issei is going to get what's coming to him for peeping on you." Kiyone responded with her arms crossed. With that response, Issei looked at his sister hurt. "K-K-Kiyone, how could you say that about your own brother?" Issei asked.

"Look girls, as much as I want to stay and watch you all beat him to a pulp, I'm here because President Souna wants a word with him."

"Awww, really?" Muriyama complained.

"And what, pray tell, does the student council president want with your pervy brother?" Katase inquired.

"Damned if I know, she needed me to do something, I'm just the messenger. Now are you gonna let me take my brother to 'hopefully' face his punishment for peeping, or are you gonna let me go back to President Souna without him and have me explain why you all kept her from dealing with him." Kiyone asked with a wicked grin, scaring both the Kendo members and Issei.

'Damn, Kiyone sure can be really be scary when she wants to be.' Issei thought to himself.

"No, no, no. If the president wants a word with him, who are we to keep her waiting?" Replied Muriyama in an innocent voice, even though she was still frightened by Kiyone's ultimatum.

"Yeah, that's right. President Souna will know what to do with him." Replied Katase.

Kiyone just smirked at the Kendo members. "Smart choice everyone. Come on Issei." Issei then got up and went to his sister and the twins walked away from the Kendo club. Issei had a relieved look on his face while Kiyone sported a beyond annoyed look. They stopped and looked at each other. "Thanks for saving my ass back there Kiyone." Issei said in gratitude to his sister.

"Hey, here's a crazy idea Issei, why don't you and those two losers you hang out with stop peeping and maybe you won't get beaten up so mercilessly every time you get caught." Kiyone suggested sarcastically.

"We're guys Kiyone, we can't help it. Come on! We're red-blooded boys, it's only natural we want to see what lies beneath a woman's clothes."

Kiyone just looked at her brother with a deadpanned expression. "Honestly, and people often wonder how it is we are related." She said as she put two fingers to her forehead in irritation. "Look, I'm going to Tomoe's house to give her some tutoring, do me a favor and try and stay out of trouble on your way home."

"Alright, alright, yeesh. I gotta go find Matsuda and Motohama first and give them a piece of my mind for leaving to take the grenades." Replied Issei.

"I think I saw them run towards the old school building." Kiyone said pointing behind her for emphasis.

"Thanks Kiyone. I'll see you at home." Issei said as he walked away.

"Remember, stay out of trouble."

"Yeah, yeah." Issei casually replied while waving his hand. Kiyone then caught up with Tomoe and the two proceeded to the latter's home to begin their tutoring session.

Later that evening

Kiyone was currently standing outside an all night diner. After she left Tomoe's house after their tutoring session, Kiyone received a text from someone saying to meet them at the diner. She looked and saw that there weren't a lot of patrons, but then looked at the far end of the the diner to see a man she was familiar with, the man who saw her running to school with the perverted trio. She looked at the man with an annoyed expression. Not wanting to keep him waiting, she entered the diner.

DING DING

"Welcome, sit anywhere you like." Said the cashier. Kiyone then walked to the booth the man was sitting at and took a seat across from him. "Well Kiyone, nice of you to join me. Care to join me for some food?" Said the man in a relaxed manner. Kiyone just continued to look at him with an annoyed expression.

"What are you doing here Azazel?" She asked the man now known as Azazel.

"What, your old instructor can swing by and say hello to one of his best and most promising pupils?"

"You're taking a big risk here, you do realize that this place is under the control of the devils, don't you? Said devils in fact are the younger siblings of two of the devil kings! One of who, I happen to be on good terms with!" Kiyone exclaimed.

"Relax will you, nobody even knows I'm here. So don't get your panties in a twist." Azazel replied, causing Kiyone to gain a tick mark. Just as she was about to say her piece, a waitress came to the booth. "Hello, can I get you anything?" She asked the brown haired fallen angel, her pen and notepad at the ready.

"I'm not eating anything, I'll just have a coffee. And put it on his tab." Kiyone replied.

"Coming right up." Said the waitress as she went to fetch Kiyone's order.

"Anyway, Kiyone-" Azazel began. "I called you here because I wanted to give you a warning."

Kiyone then looked at her former mentor with a questioning look. Before she could say her piece, the waitress came with a pot of coffee and Azazel's order. She placed the food in front of Azazel and poured it into the cup in front of Kiyone. ""Thank you very much."" Both thanked the waitress, who smiled in return and went to serve other tables. Kiyone took a sip from her cup before looking back to her former instructor. "So what did you want to warn me about?"

Azazel took a fork and dug into his meal. "Well, I don't know if you are aware but I believe your brother may have a sacred gear in him." He replied before he took a bite of his food.

"I've been sensing something inside my brother for a while now, nice to know I wasn't losing my mind. So what kind of sacred gear do you think he has?" She asked as she took another sip.

"I don't know yet, but I think it might be something very powerful. Listen Kiyone, I need you to keep an eye on your brother. If my hunch is correct about his sacred gear, there will be people who be gunning for him because they will deem it and him too dangerous to be kept alive. Think you can do that?"

Kiyone looked at Azazel with a determined look on her face. "Need you ask me to do so? You told me when I became a fallen angel and gave me my sacred gear, I could have the power to be able to protect family, didn't you?" Kiyone asked rhetorically.

Azazel just smirked at his pupil. "I'm glad I can rely on you Kiyone. I expected nothing less from you."

Kiyone returned a smirk as she finished her coffee. "Thanks for the coffee." She then grabbed her school bag and proceeded to the exit. The cashier thanked Kiyone for her patronage as she left the diner. Kiyone continued to walk as the sun started to set, contemplating what Azazel told her. Being told that there would be people coming after her brother was a shock to her. While she doesn't agree with Issei's 'tastes' and finds him annoying at times, she loves her brother dearly and would do anything to protect. Taking a shortcut in an alley, she stopped walking for a moment and looked at her right hand. She concentrated and suddenly.

FLASH

A Jericho 941 pistol appeared in her hand. She also brought out her fallen angel wings. She brought it up close to her and a serious and determined adorned her face. 'I was given power to protect the people I love. I won't let anything happen to them, not as long as I am around to protect them.' She swore to herself. With her resolve strengthened, she dissipated the gun, retracted her wings and then continued the walk to her home. After walking about four blocks, she finally arrived home. She used her key to unlocked the door and went inside. "I'm home." She called out.

"Kiyone, Kiyone, it's a miracle!" Her mother exclaimed as she came to the front door to greet her daughter. Kiyone just looked at her mother with a confused look.

"Uhhhhh, what's a miracle mom?" She asked.

"Issei...finally managed to get himself a girlfriend!" Mrs. Hyoudou replied.

Kiyone continued to look at her mother with a confused expression. She knows Issei is a pervert with an unhealthy fascination with women's breasts, there was no way he could ever get himself a girlfriend. "Uh mom, I think I must have misheard you. Did you just say Issei had a girlfriend?"

"You're damn right she did Kiyone." Issei said with pride in his voice as he made his appearance.

"...WHAAAAAAAAAAT!?" Kiyone shouted in disbelief.
