Summary:Our favorite tsundere hunter is about to give birth to a miracle. There are vampires wanting to be the father. Yet who really is the father? Let's find out. Warnings: Yaoi, mpreg and Yuri.

Zero's baby

Inside a simple, small and was the picturesque of normalcy house. Sat a beautiful creature with long moonlight silver hair and a pair of shining lilac eyes on a rocking chair. The creature in description was none other than Zero Kiryu the most popular hunter in the Hunter Association and was much feared because of his infamous glare.

It has been many years since the fall of Rido and most of them had settled for the usual way of living.

Zero sigh in content as he gazes at the full moon that was the center of the night sky. As he rocked himself on the chair a smile formed on his lips as he recalled all the past events on his life.

His parents' death…

His vampirism…

His loneliness…

His pain…

Shizuka's appearance…

Ichiru's comeback…

Shizuka's death…

Yuki's awakening…

Ichiru's near death experience…

And the moment he fell for his husband…

Yes, you read it right. Husband. A smile formed on Zero's face as he let himself immersed himself on the memories that he shared with his vampire husband who was now out because of his work.

Being a hunter, you would surely think. Why Zero wasn't currently hunting? Well the answer would be…

*Ba-thump* *kick* Ba-thump*

Zero chuckled as he placed his hand on his huge baby bump. Massaging his hand on his stomach.

"Don't worry, your father will be back soon." He admonished to the miracle inside him wanting to comfort the baby who for sure knew that the father wasn't there.

*kick* *kick* *kick*

Zero groaned in pain as he felt the baby kicked with more fervor. He slowly stood up from his seat and thought that maybe it was the chair making him uncomfortable.

The baby kicked and kicked resulting in having Zero feeling more frantic than ever realizing that the baby was already wanting to see the world. Even more so, that his husband wasn't here. He clutches a hand on his stomach and head for the nearest telephone.

Quickly, he dialed his foster father's father. Who he knew was the one nearest to their house. A few rings and Kaien immediately answered.

"Cross Residence. If you're looking for Chairman Cross. It's him speaking to you so give a big hurray for it!" Came the over cheerful voice of his foster father.

Just hearing his antics got Zero to growl and be aggravated much more.

Breathe… Just breathe… Zero…

"Get here." Zero breathe out in a calm tone. "It seems your grandchild is much excited to see the world."

….

There was no answer at the other side of the phone, making Zero run a sweat and think that Kaien must have either fainted or stupidly have now a jawdrop expression. He was about to hang up and try another family member when—

"WHAT! MY GRANDCHILDIE WANTS TO BE BORN RIGHT AWAY!" Cross shrieked so loud that Zero had to get the phone far away from his ear to avoid permanent ear damage.

"Cross—"

"WHAT TO DO YOUR HUBBY IS NOT THERE LEAVING THE MOMMY ALL ALONE!" Zero growled in frustration, it's true that he was the one doing the birthing here but hell! He was still a man!

"I- ME-MEAN THE BRIDE HUSBAND! OH! WHAT TO DO!" Cross immediately rectified his mistake sensing Zero's anger.

"Cross—" Zero tried again only to be cut off by yet another shriek from Cross.

"WHAT MUST I BRING? KEY, HANDIPACK, MILK AND CEREAL?" Zero sweat drop because of Kaien's words and had already regretted calling the chairman.

"WHAT TO DO!"

"Cross…"

"AND YOUR ALL ALONE THERE!"

"Cross…"

"OF ALL THE TIME, WHY IS IT THE LITTLE ONE WANTS TO POP OUT WHEN THE FATHER IS NOT THERE!"

"Cross…" By now dozens of bulging stress marks have appeared on Zero's form. He was getting more and more pissed of the Chairman's idiocy.

"WHO WILL NOW HELP YOU, YOU'RE ALONE!"

"Cross…" Zero was already near his breaking point, teeth gritting and hand clenching tightly at the phone. Why else would he call him? Of course, Cross was the one supposed to help.

"OH! WHAT WILL HAPPEN NOW TO YOU MY ZERO-CHAN!"

That does it…

"WHO-"

"GET THE FUCK HERE ALREADY! WHY ELSE WOULD I CALL AND STOP WITH ALL YOUR SHIT. OH, SO HELP ME. I WILL NEVER GET TO GIVE BIRTH TO YOUR GRANDCHILD!"

"Hai! On the way!"

A yelp was heard on the other side as Zero knew by now that his annoying foster father is no doubt already panicking on getting there.

"Ouch, my foot!" Kaien cried, Zero could identify more shuffling since Kaien forgot even to hang up.

Hearing a door slam on the other side, Zero hang up relieve that any second Kaien would already be at their house any minute now.

*kick*

Zero massage his bump, feeling his baby's distress.

"Shh, it's alright. Your grandfather is coming." Zero cooed. One energetic kick was what he received from his unborn baby. And Zero felt blissful and blessed.

*SLLLLLLAAAAAAAAMMMMM*

Zero was startled leading to a pair of lilac eyes quickly gazing at the now opened door. He sighed in relief for the very person who slammed the door open was none other than Chairman Cross who was panting hard, his hand still on the doorknob.

"Ze-ze-zero I-I-I ma-ma-made i-i-it." Kaien admonished, panting as he did so. Zero nodded and his heartbeat quickly calmed down.

Without further ado, Kaien set to work in getting all the items while Zero watched and point out the needed items.

"Got the map!" Kaien cheered, then opened it. He saw all the marks and circles also the distance from the house to the hospital. "It's a good thing your husband had already made a sketch plan."

Zero was about to reply when he felt a series of contractions coming ahead. He groaned in pain that got him placing a hand on his stomach and Kaien to be in a very restless mode as Kaien scrambled to get all the items.

*drip* *splash* *squelch*

Both Zero and Kaien look at each other in the eye. Both wide and more frightened and nervous than ever. Zero look down at his pants now seeing the distinct wetness there and more liquid that fell on the floor.

"I-I-I th-th-th-think m-m-m-my wa-wa-water ju-ju-ju-just bro-bro-broke." Zero stuttered, his heart that was once calm turned to a whirlwind of thudded beats.

Kaien with all the items in his hand, made a beeline for the car that was park near the house, then back inside for the other items that was left.

Getting inside the car and starting up the engine. The car roared to life and he set off to the road to the hospital.

"Don't worry Zero we'll get there fas-" Kaien's words left him as he turned at the backseat and saw that it was empty and Zero free. Making him face palm himself as he realized his foolishness.

Quickly, he drove back to the house and found Zero already at the door. Kaien gulped as he saw Zero's livid face. The silver haired beauty just sighed and with Kaien's help he laid himself on the backseat.

Then they were off and speeding up into such speed that could make the greatest race cry in envy.

:*:*:*:*:

Breathe in…

Breathe out…

Breathe in…

Breathe out…

Zero continued with that mantra on his head as he felt the contractions pulsing up inside him. He was on a hospital bed and the doctor was already there checking his vitals and then proceeded to let Zero bite into the ice as the contractions became more rampant than ever.

The doctor left and Kaien was at Zero's side in an instant.

"You're doing good, Zero-chan keep it up." Kaien cheered but let out a yelp as he was suddenly tugged down by Zero who had his hand clutch his scarf.

"Call him now. He has to be here." Zero said in a cold voice that got Kaien shaken up and nodded frantically.

Kaien left to make a phone call, leaving Zero alone who continued his routine along with his palm on his bump.

Be strong baby…

We can do this…

Be strong…

When the doctor came back and deemed that Zero was ready to deliver. The nurses quickly get him to the room. Kaien tailing behind them.

"Where the fuck is he?" Zero asked, trying to relax.

"He's coming Zero." Kaien comforted as he saw Zero doing more of his breathing as he was carried by hospital bed to the delivery room.

"Cross." Zero whimpered as he knew that he was being taken now inside to the delivery room the door closed in front of Kaien who was on the phone talking to someone he was sure would be his husband just by the loud voice booming on the phone.

:*:*:*:*:

Zero pushed harder than he had ever done much more with the order and encouragement of the doctor. As he felt himself being stretched beyond belief. He cussed and cussed in his mind as he keeps on pushing forward just to get their baby out to the world.

Hell! It's so painful. I'm never going to let that bastard in me ever again!

"Just one more push," the doctor requested and Zero did. He cried in pain as he let out a huge push until he felt his consciousness nearing its end. With a breath, he felt tired and laid back on the bed.

Bunches of sweat covered his face and he felt even more dazed and weak. Thus, tempting him to close his eyes.

*baby cries*

Lilac eyes suddenly opened and stared in wonder as Zero gaze at the bundle of joy now at the doctor's arms.

"It's a healthy boy. Congratulations." The doctor informed with a smile as the nurses assist the doctor in cleaning the baby and putting him on a blue cloth.

The feeling was indescribable as he felt tears form in his eyes while gazing at the most amazing miracle he had ever seen… His own son.

"You're so handsome." Zero whispered at the baby whose eyes suddenly look at him as the baby boy seemed to understand what Zero had said.

A genius just like his father.

Zero smiled and reveled in the feeling that he was able to bring out such enchanting creature to this world. Seeing that his son was being taken care of, Zero let himself rest and close his eyes due to exhaustion.

:*:*:*:*:

Zero brightly smile as he was now holding the miracle on his arms while he was on the hospital bed already fresh and clean. He was immersed in just watching his son sleep and head to dreamland as the doctor check him again.

"Your son is lovely." The doctor complimented. Then his head furrowed in confusion as he suddenly asked Zero. "May I ask who's the father?"

"Oh, his name is—"

*SLAAM!"

Both Zero and the doctor was startled as the door opened with a great slam as the person with garnet eyes and dark brown hair made his presence known.

"That would be me." Came the arrogant and full confidence voice of one Kaname Kuran as he strode inside and made his way to Zero. His garnet eyes lingered on the sleeping baby who did not even woke up from the slam of the door. "You made me proud, Zero. You've given me an heir." The vampire king smiled.

"HOLD IT!" came another voice that belongs to none other than a bright cheerful Takuma who went in as well with a dashing smile on his face. "I believe that title belongs to me. Zero and I had a past."

"No, Zero and me had a drunken affair once." Kaname coldly argued.

"WHO SAID THAT ITS EITHER YOU TWO! OF COURSE, ITS ME!" a certain orange haired vampire shouted as he too went inside and joined the two in the argument. He was known as Akatsuki Kain.

Yuki came barging in as well. Long wisps of brunette hair dancing as she clings her arm to her husband who was the younger twin of Zero.

"Hey! Congrats Zero. He looks super cute!" Yuki complimented, bubbly as always.

"Congratulations. Onii-chan. So, did he really come from your ass?" asked a smirking Ichiru who quickly smacked by Yuki because of his words.

"Language! There's already a baby here." Yuki chastised. But her attention suddenly went to the three bickering vampires in the room.

"No, it's mine!" Kaname

"No, that baby is my son!" Takuma

"Give it up you two, everyone knows that I'm the father." Kain

"All of you shut up. It's pretty obvious I am the father." A cold voice resonated in the room as Senri Shiki made his appearance and gaze at the three male vampires with such icy gaze.

"Dream on!" Takuma

"Your way too young to meddle in my affairs cousin!" Kaname.

"I am voting for Kaname!" Yuki cheered jumping up and down.

"I don't give a fuck!" Ichiru shouted as the four vampires bickered and argued amongst themselves.

"I'm the father!" Kain

"No, I am!" Takuma

"I am the King so it's mine!" Everyone sweat dropped at Kaname's words.

"Just give up, I'm the father." Shiki.

The doctor's eyes were shifting between the men's faces all confused by the situation. Zero could only shook his head as he watched them argue on and on.

"Well, just have to let Zero tell us who's the father." Takuma advised gaining the attention of the other three bickering vampires.

"Yes, being the mommy-"Zero glared at Kaname who didn't even flinched as he said it. "Zero surely knows who's the father."

Both Kain and Shiki nodded in agreement. Four equally handsome vampires look at Zero and the baby who just felt cornered by their gaze.

"So, Zero who's the father?" the room suddenly was silent as the four vampires simultaneously asked that question. Even the doctor and the other occupants in the room waited in baited breath to hear Zero's answer who felt even more nervous.

"I-" Zero started but got cut off as all their attention snapped to the doorway as they heard in the distance running feet going to the room.

A shuffling of feet came as a blonde-haired vampire with blue azure eyes came to the scene panting hard as he did so. There at the doorway stood a disheveled and haggard Aido Hanabusa who quickly sigh in relief as he saw Zero and the baby.

"Hon, are you alright? Chairman Cross called me. I came as fast as I could." Aido informed with such tenderness and love in his eyes as he heads near at Zero's side.

Kissing Zero's forehead as well as placing a palm on the baby cherubic face. Zero smiled happily finally that his husband had arrived.

"Sorry, I'm late. I never get to see his birth. He looks like the ever awesome me." Aido smirked and Zero scoffed at his arrogance albeit a smile was still on his face.

"It seems, Airo was the one who came." Zero said with joy as he recalled the names he and Aido planned for their baby. If it was a boy Airo a combination of Aido and Zero. If it was a girl Kirana a combination of Kiryu and Hanabusa.

"Yeah." Aido replied wistfully. Too elated in the knowledge that he was now a father.

The people inside suddenly quieted down as they saw the baby wake up and opens his baby blue eyes. Eyes that were a likeness to one Aido Hanabusa.

The air crackled with such force and intense auras as the vampire who were arguing felt jealousy course in their veins. As they realized that they lost to Aido without even knowing it. And the two were already married for goodness sake!

Zero gazed behind Aido and saw the murderous expression of the four vampires and gulped. He knew that he and Aido kept quiet on their marriage as well as the pregnancy but because of a certain idiot chairman news of his pregnancy leaked out. Resulting to this predicament they were in.

"Oi! Zero congrats!" came the boisterous voice of Kaito Takamiya who was with Yori Wakaba his once student now wife who also expressed her congratulations on the couple.

"Good job student." Came the proud voice of Toga Yagari as he went inside as well followed by a hyperactive Chairman who was already dancing with flowers on the background because of joy.

The newcomers were too oblivious for their own good as the aura in the room became more intense.

"Hana." Zero called Aido's attention who was focused on Aero.

"Hana." Zero tried again much more desperate this time as the air got heavier.

"Yes." Aido replied lovingly coupled with a kiss on Zero's lips that got the aura to become more intense than before. "Love you, and thank you for this happiness."

Zero smiled but now more nervous. "Hana, I love you too as well. But you better run." Zero warned that got Aido's attention.

"Hanabusa." Came the glacier like voice of Kaname and Aido felt chill crept up to his spine and when he looked back he saw green emerald eyes, garnet eyes, burnt orange eyes, and blue melancholic eyes burning with deep loathing and fury.

"SHIT!" Aido cursed then sprinted off as the four vampires chase after him leaving the remaining occupants laughing on what just happened.

:*:*:*:*:

Ruka and Rima was holding hands as the lovers were heading to Zero's room in the hospital with Seiren trailing behind them. Ruka and Rima had gifts that were clutched on their hands that was not connected with the other. The lovers were so immersed with each other that Seiren just shook her head at them while she was also carrying her own gift for the silver haired hunter.

"GET BACK HERE YOU ASSHOLE OF A COUSIN!"

Just like that the moment was gone as the trio's eyes widen as they saw Aido sliding down the hall using his ice powers. The doctors and nurses around them seemed to not even one bit fazed and continued with their work like this was just a usual occurrence. Why wouldn't it be in a specialized supernatural hospital?

What got the trio even more flabbergasted are the vampires also chasing Aido. There was no doubt about it that the one who just shouted was none other than Kain who was already hurling fireballs on surfing Aido with his ice waves.

Aido dodge his own cousin's attack coupled with the blood whip sent to him by Shiki as well.

"Whoa!" Aido exclaimed almost being stabbed by Takuma who throw his katana at his form. Kaname was the worst of them all as glasses inside the hospital cracked and a tornado of items came spiraling about. While the person doing it was walking calmly yet with furious garnet eyes.

As Aido reached the front gate of the hospital he looked back at Takuma, Kain, Shiki, and Kaname who sent a chorus of insults and degradation to him.

"Bastard, you took Zero from me!" Shiki exclaimed with cold eyes. His nonchalant manner all down at the drain.

"You don't deserve him." Kaname nonchalantly said but his garnet eyes were a different case since it clearly says. "GO SOMEWHERE AND DIE!"

"Fu,fu,fu, Aido you were hiding this from us huh?" Takuma darkly chuckled, his katana now in his possession glinting sharply that just reflects Takuma's pissed mood. He looked even more spooky with his saccharine smile on his face.

"YOU PIECE OF SHIT!" Kain definitely was the most pissed in the group for it was his own family who betrayed him in having Zero.

Aido gaze at their furious faces as the temperature and atmosphere became cold due to his own volition. The vampires feeling this did not backed down easily as they too let their aura out. Aido was about to send forth something great but—

In just a blink he dissipated it as bright light and sparkling dusts hovered on his form as he let out a dashing smile and an outrageous wink to Kain, Takuma, Shiki, and Kaname.

"Sorry boys, it seems I am really the winner of Zero's heart." Aido proclaimed with a flick of his hair and quickly dodge more of the furious vampires' attacks as he got out of the hospital still being chased by four livid vampires.

Ruka and Rima blinked while Seiren was trying to not even give off a hint of a chuckle to what she just witnessed. The people at the hall just carried own their work like there was nothing amiss.

Looking at each other's eyes and a silent agreement of just plainly forgetting what they saw. They head to Zero's room completely ignoring the distant explosive sounds behind them because of five vampires fighting.

:*:*:*:*:

Omake

"Zero! You, sneaky devil you! I was hoping it was my onii-chan's!" Yuki shrieked, crossing her arms on her chest with a pout and stomping as well. That her favorite yaoi couple did not happen leading her to throw such childish tantrum.

"Aido, huh. You've always had a thing for blondes." Ichiru smirked much to Yuki's annoyance.

"But how come Aero has dark brown wavy hair?" Toga asked that got the others attention, gazing at the baby it was in fact true it bears similarities to a certain pureblood.

"Yeah, and the baby's jaw looks like Kain." Cross pointed out.

"The lips Takuma's" Kaito noticed, eyes getting wider each second.

"And finally, the shape of his face like Shiki." Ichiru sneered as he feels like this was becoming more and more fun. Seeing the flushed face of his onii-chan he felt like he had hit the jackpot out of all the embarrassing situations Zero had.

"SO, ZERO WHO REALLY IS THE FATHER!" All of them chorused to a very overwhelmed Zero who simply tsked and shrugged.

"Beats me. They all came inside of me simultaneously in one night." Zero confessed blushing as he recalled his one drunken night rendezvous with those vampires and his husband. It was just for fun but too many drinks can really make you forget the right thing.

*PLOP* *PLOP* *PLOP*

Zero and the others who had a jawdrop expression from Zero's revelation got their eyes snapped to the doorway as they saw Ruka, Rima and Seiren fainted because of what just Zero said.

Now the question remains. Who do you really think is the father? Hehe…

Hate it or Like it?
