~000~

Yukari Kasumi was an unfortunate girl. Because, after the first day after she was born, someone cruel gave her a serum of Werewolf and Vampire, making her half werewolf and half vampire while all of her families are humans. This, makes Kasumi become an outsider for her cousins but not to her older siblings that cares for her.

"We'll protect you Kasumi, trust us!" That was the promise made by her brothers, Kisetsu and Kasetsu also her sister, Kinata. When she heard this, the little Kasumi smiles and promise them to practice to control the other side of her.

Until she was 7 years old. Her families are murdered because of her, making her go rampage on the people that killed her parents and siblings. After her rampage, she stayed at the almost broken house, crying herself to sleep.

The next day, a boy, a years older than her, walks pass her house with his parents and cousin. Sensing her presence, he ran to the house and found her. The boys parents decided to adopt her as their daughter and they changed her name into Kazama Kasumi.

Now, 9 years after, the girl almost reach her puberty and schooled at the same place as her adoptive brother and cousin, living as a human at day, werewolf and vampire at night.

~day 1 : start~

"Kasumi, wake up girl, it's time to school" the soft sound of a woman in her mid-30 wakes the sleeping girl that still covering her body with her soft and fluffy bed cover.

"Can I wake in 5 minutes, Kaa-san? Nii-san and Nee-san takes me outside until 3 last night..." She mumble and the woman sigh.

"When I already told them that the maximum time for you is at midnight if it's school day or Sunday" the woman said and the girl opened the bed cover. Her light blue hair was straight down reach her waist and her light blue eyes are still closing. Don't forgetting a wolf ears are coming out on top of her head with the same color of her hair.

"You became wolf last night?" The woman asked while sitting down near the girl and the girl nodded, covering her mouth then yawning.

"Okay then, 5 more minutes, at least until that ears are gone" the woman chuckled while playing with her wolf ear. The girl nodded and covered her head with the bed cover and the woman left her.

"Kaa-san, did she awake already?" Ask a boy that's wearing her school jacket and beside him, his cousin standing there also, wearing her tie correctly.

"Well, thanks to the two of you, she'll be sleeping for another 5 minutes, Kouku, Kaori" the woman scold the two teenagers while the two of them just grinning.

"Maybe because Kasumi's so adorable whenever she's in her wolf form~ Her fur just so soft to touch" Kaori said while giggling and that makes the woman sigh.

"Well, she will sleep for another minutes. Wakes her up okay" the two teenagers nod and the woman leaves them.

While inside Kasumi's room, she's already sitting on her bed while covering her face with her hand that rest on her knee. Her wolf ears are still twitched when she hears her mother's steps walks away. She sigh and focusing her mind to make the ears gone. When the ears gone, she went to the bathroom and washed herself. Wearing her uniform, took her bag, she get out from her bedroom and walked to the dining room.

"Ohayou..." She greets and Kaori greet back.

"Ohayou, imouto~ I was planning to wake you just now" she said and Kasumi just shook her head.

"No need, Kaori-nee... I can't sleep once I awake..." She said and Kaori just gave her a small smile, her emerald eyes looking at Kasumi's light blue locks before she pats it.

"Kasumi, you better eat breakfast now so we can leave now" Kouku said and Kasumi nod, sitting herself next to Kaori and eat her toast. After a while, they finished their breakfast and walks towards the door.

"Tou-san, Kaa-san, ittekimasu!" Kouku shout when walking towards the door and there's another shout from inside from their mother and when they passed their father that sits in the living room, Kasumi see a frown on her father's face which is rare to see.

'Is there something bad will happen?' She thought while running towards Kouku and Kaori that already running a few meters in front of her.

Kasumi isn't exactly Kouku's little sister nor Kaori's cousin because 9 years ago, she was adopted from Kouku's parents as Kouku's little sister that he always want it. Once they knew that she's a human that being injected a werewolf and vampire serum, their father, Kazama Kazuya, decided to train her so she can control it well. And the result, every time the clock ticks at midnight, the three kids will go to the forest near the house to train or hunt some animals to feed Kasumi's wolf and vampire side.

"Nee, nee-san, nii-san, aren't we going a bit too fast?" Kasumi ask between her pants and Kouku just glance at her before answering.

"No we're not, just hurry up because we need to do something first" he said and Kaori just laugh a little.

"Yeah, copying someone's homework because you forgot to do it last night" she mocked and Kouku just hit her head.

"The last one arrive at the school yard treat us at the cafeteria for a week!" Kouku declares and fasten his pace.

Seeing this, Kaori also run faster and Kasumi just sigh. Having a werewolf part in her body, she has an advantage on running because whenever she in her wolf form, she always running with her paws. So she stops, kneeling before she run so fast, and passing both Kaori and Kouku, making Kouku whine because he lost to Kasumi yet again while Kaori just laugh seeing her adopted cousin run with the speed of her wolf form.

"Seems like I win again, Kouku-nii" she said while fixing her skirt that folded up, revealing her thigh and Kaori stop beside Kasumi, looking at Kouku that lose to his sister for the umpteenth time.

"Fine, I'll treat you girls" hearing that, Kaori and Kasumi high five each other before they enter their school.

The three of them are in a same school that was build by their grandfather, Kazama Hikaru called Kazama Polytechnic Academy or they always called KPA and the three of them are at the same section. Kouku at the 3rd year at High School while Kaori and Kasumi are at 2nd year at High School.

"Kasumi, you already did your homework, aren't you?" Kaori asked when they change their shoes into indoor shoes and Kasumi nodded.

"I did it before went hunting last night" she said and turned to Kaori while closing the shoe locker.

"See? Even Kasumi already did it, unlike you, Kouku" Kaori grinned at Kouku that fist his hand on the locker.

"Shut up! I'm not doing it because I have to prepare for yesterday's hunt!" Kouku shouts and everyone looks at him including Kaori and Kasumi glaring at him.

The two of them drag Kouku to the garden behind their school and cornering him.

"I thought we agreed to not talking about that loud, Kouku-nii" Kasumi said and Kouku just looked at her with apologetic eyes.

"I know... Sorry... It just slip out my mouth" he said and scratched the back of his neck.

"Well you better be. Next time, we'll kick your ass" Kaori threaten him and pulled Kasumi's hand to their class while Kouku walks to his class.

~in class~

Kaori and Kasumi sit side-by-side with Kasumi near the window and Kaori sit on her right side. They reading a book while waiting the teacher and sometimes they'll chat only for a couple of seconds and they return to their book.

While Kouku sit at the front sit near the window and talking with his friends that at the same club as him, soccer while the girls are archery club. When the bell rings, the kids are return to their sit and the teacher walks in.

"Okay kids, let check attendance first..." The teacher said and start calling the students name one-by-one.

"Seems like everyone are present, well then, shall we start the lesson? What about... Collecting the homework first?" The teacher ask and the boys are groaning because they didn't finish or start it just yet.

While the other kids are collecting it, and the boys are grounded, the headmaster, or Kazama Hikaru is watching his students, especially his grandchildren. Kouku is lazying himself in class, Kaori is take notes of her teacher while Kasumi just gaze out to the window. Hikaru just chuckle at his grandchildren's attitude that almost remind him of himself even tough Kasumi isn't his real granddaughter.

"Headmaster" a call from outside the headmaster's room makes him turns around and see his secretary with a tall man around his mid-30 with red blazing hair and a pair of blood red eyes. Hikaru stands up and walks to the man and shake hands with him.

"I've been expecting you, my old friend. Why don't we have a sit" Hikaru offered and the man just nod and sit in front of Hikaru.

~lunch break~

"Eh? What are you talking about, Shin?" Kasumi ask her friend that eating one of her octopus like sausage and answer her.

"Well, that's what I heard. Apparently, it's start when you become a vampire a few nights ago" Shin answer and Kaori just looking at them.

"How do you know about this, Shin? I mean... You're not that fond of vampires and werewolf back then" Kouku comment and Shin just laugh.

"I become fond of them since I know that my cousin here is one of them~" Shin said while hugs Kasumi and she just break his hugs.

"Half-breed. I was born human, Shin." Kasumi said irritatingly and Shin just grin like a cat.

"Well, but you're infected when you're a baby. So I conclude that you are born half-breed" Shin said and Kasumi sigh.

"Just say anything you like because I'm not giving you my octopus sausage again" Kasumi said and Shin whine at her.

Kamiya Shin is one of Kouku, Kaori and Kasumi's cousin. They also know that Kasumi was a half-breed and also keeping it a secret. Shin is a month older that Kasumi but act like a year younger than her, which really annoys the three of them.

"Hey, did you heard it last night?"

"A howl right? What was that?"

"Duh, it's definitely a wolf"

"But there's no wolf that can howl that loud"

"Well, maybe the wolf use some kind of microphone"

And the gossip girl laughing and that makes the four siblings laugh even harder because the wolf that howl last night was Kasumi because Kouku told her that she can howl as loud as she want so she howled very loud.

The girls are looking at them while whispering at each other and Kasumi still can hear it.

"What are they talking about now, Kasumi?" Kouku ask and Kasumi just waved her hand.

"Just some crap" she said and continue to eat her lunch again. After they done, they return to their classes until Hikaru's secretary run into them.

"Ah, Kiriya-san" they say in union and Kiriya looks at them.

"Ah, what a coincidence, I need Kasumi-san and Kaori-san. The two of you are called by your grandfather" after saying that, Kiriya walks away only to trip her own foot, making the four of them sweatdrop.

'She's still clumsy...' The thought and Kasumi walks away.

"Kaori-nee, let's go meet ojii-san and return to class" she said and Kaori nod. Waving to the two boys before disappearing to the headmaster's room.

~headmaster's room~

"Jii-san, it's me and Kasumi" Kaori said while knock and opens the door.

"Ah, you girls are here. There's something I need to tell you two. Well, actually to Kouku too, but you two can tell him in but you two can tell him better than I am" he said and the two girls nod and sit on the couch in front of their grandfather.

"Okay, I know this is sudden, but the two of you are the only girls that bears the 'Kazama' name, while the other aren't. So, as Kazama's, I want to ask a favor from the two of you" Hikaru said and the atmosphere suddenly drop and the two girls didn't like it. Kasumi, being silence since they enter the room just take a deep breath, waiting for her step grandfather continue.

"One of you have to become the heir of the family" hearing that, Kaori and Kasumi widen their eyes in shock.

"Wait, jii-san. Isn't Kouku will be the perfect heir? I mean, he's older than the two of us, he bears the 'Kazama' on his name, he has the power as same as tou-san and-"

"And yet he still can't act like one"

That words makes both girls stuns and Hikaru just sighed.

"The reason I choose between the two of you, because you can bear children and the your power to save people all bigger than Kouku's, because you're female" he explain and Kasumi just look down while Kaori just shook her head.

"Nee, jii-san... Can the three of us talk about this first?" Kasumi ask and Hikaru nod his head.

"Of course you can, you two are dismissed" after that, Kaori and Kasumi walks out of the room and to their classroom.

Hikaru sighed. Sensing their aura has drop, and if Kasumi showed her wolf ears, he sure it'll flat to her head like a lost puppy.

"This is for the best of Kazama..." He mumbled and looked out of the sky"

~at home~

"What happen to both of you? What did jii-san talk to you until your aura's dropping like this?" Kouku asked them while working on their homework and Kaori just sighed.

"Kouku, we need to talk. The three of us" she said and Kouku move his sitting position so he can get close to his sisters.

"What about?" He ask, looking at Kaori and Kasumi one-by-one.

"Jii-san talks about between me and Kasumi... One of us have to become the Kazama heir..." Kaori starts and Kasumi just averted her gaze to somewhere else.

Kouku just looking at them and ask "Then what else?" That question makes the two girls look at him and he just tilt his head.

"I know that the heirs of the Kazamas are all woman, because they can bear a child. " He said and Kasumi protested him

"But it doesn't make any sense, Kouku-nii. Every family that I know has their son as their heir. Except they don't have a son" she said and Kouku just nod.

"Did jii-san say why I didn't the one who become the heir?" The two girls nod and answer

"Because your act doesn't like a heir" and that answer makes Kouku laugh. A pair of light blue and emerald eyes looking at the red haired boy that still laughing and then he's stopped, his warm red eyes watching his sisters and ruffle their head.

"That was only excuses. I already know, even tough jii-san ask you to told me" he said with a grin and Kaori asks him.

"You knew it? What do you mean?" Kouku looks at Kaori and grin.

"My power is telepathy remember? I can hear three of you talking about it. And I'm not angry, don't worry. But I will if one of you reject it" Kouku said and the two girls just smile and hugs him.

"Thank you, Kouku/Kouku-nii" Kouku just hug them back and ruffle their head again.

"Well then, you want to go hunting again?" He ask and they nod. Kasumi rise first, stripping herself before tuning into a big wolf with light blue fur and bright blue eyes.

"Okay, let's go!" Kouku shout and the three of them leave the house by jumping out of the balcony.

Meanwhile, Hikaru, Kazuya and their mother, Jun are talking about them.

"Tou-sama... Was it really fine? I mean, your friend's son were human. It's fine if he choose Kaori, but what if he choose Kasumi? He didn't know what she's capable of" Jun ask Hikaru while her eyes following her son, niece and adopted daughter slowly out from her sight.

"This is for the best, Jun. Whoever he choose, weather he choose Kaori or Kasumi, he has to take the risk" Hikari said and Kazuya and Jun only nod, watching them already off their sight.

Without they knowing, Kouku and Kasumi heard their conversation and Kaori knows something's weird with her grandfather, uncle and aunt.
