Chapter 1: Birth of Project Usagi.

(Tokyo Kingdom, underground laboratory)

Kiryuu Sabato now in his laboratory to create the perfect bio weapon that can potentially be the downfall of not only Edwin Black his superior but the Taimanins as well. Along with capturing the taimanin Murasaki to make her his slave.

He needed to make a perfect chimera class demon. One that has intelligence. Can be twice adaptive, stronger, faster, and very hard to kill. Since the Taimanins always find ways to kill his beloved creations.

Today he has sent drones to collect the DNA sample of a very mythical legend or monster that has known to guard this Holy Grail. He managed to find some remains of this "Killer Rabbit" which was killed by the king and his men with that holy hand grenade, Kiryuu collected its hair sample from the cave of Caerbannog along with little of it's skeletal remains that is still intact when the Holy hand grenade blew it up.

Smiling he pushed his glasses up. Happy to bring this creation to life.

This will be the ultimate creation. He could fuse its genes to make it into a Chimera. Having stolen some Dna samples of Edwin Black the Vampire king would be a great idea for his creation. He intends on making it part human, now he needs the finishing touches for his creation. He could make it part incubus maybe he can steal DNA from the Incubus King Kuroi Ryuji. Since he is aware of the War between Nomad and the Incubus Faction.

Kuroi Ryuji seeks to become the Demon King of the Dark World, yet Edwin Black is after the same thing and they have been at each other's throats for a very long time. Perhaps his creation once produced can kill not just Edwin Black but Kuroi as Well!. With this bio weapon at his beck and call possessing the blood of two of the most strongest beings in the dark world no one can oppose him! He can conquer not just the dark world but the human world too and conquer the UFS!.

Smiling like the mad scientist he decides to send robotic like mosquitoes spreading 500 of them, incase the incubus king destroys them.

"Now.. what else should i give you my dear creation. You'll be more Killer Rabbit than your ancestor has ever be!" Kirryu says with a evil smile looking at the creation that is in a small tube/Capsule in light blue liquid.

(With Kuroi Ryuji)

The demon king sits on his throne drinking some wine. As he is currently scheming and planning. To become the next demon king of the dark world.

Along with having Mizuki Shiranui. However his thoughts would be interrupted when he feels a mosquito bite him. With an annoyed look he attempts to smack it but it flies off before he could kill it. Frowning in annoyance he waves it off, it was just a pathetic parasite.

(Kiryuu's lab, one day later)

"Yes..! YES! this is perfect! I now have the blood of Kuroi Ryuji! The incubus king!. But as a precaution should i not be able to receive the incubus king!'s blood i have taken wraith essence, since the killer rabbit in its time did represent death. My perfect creature will surpass all chimeras! And will destroy all my enemies!" Kirryuu says with a sadistic smile.

"Now let's merge them ALL!" He says looking at the capsule that contained his creation. He would merge the Killer Rabbit's DNA. with the blood of: Edwin Black, Kuroi Ryuji, Human blood, and Wraith essence.

The Cell, in the incubation capsule would glow a light purplish color. As all the DNA's merged into ONE.

It would begin to rapidly change form. First a skeleton was formed, then organs, then muscles and tendons and finally skin was wrapped around the unknown creature. A reddish cocoon formed around it and pulsed as its heart took its first beat.

Kirryu smiled. Watching in curiosity as the cocoon in the incubation capsule had grown at 4'9 feet tall.

(8 Days later)

Kirryu would return to his lab and just in time he sees the cocoon began to break free. Kirryu grinned his creation is awakening.

As it began to tear the cocoon from itself. He immediately opened the incubation capsule as the incubation water spilled along with the cocoon.

The creature had successfully freed itself from the cocoon and goo that was attached to it. As it wobbled on its on feet. Standing at 4'10 feet white hair, white rabbit ears growing from the top of its head. A single horn growing from its forehead. Its skin was Albino colored, it opened its eyes revealing its color that resembles blood. As it looked around seeing itself in a laboratory of some form. The creature looked to be a male, a young boy. That looked between the ages of 10 or 11.

Kirryu stared at his creation that is a child.. yet it least he can mold the creation into his own liking.

"Hello my dear creation! You will soon grow to become the ultimate weapon and of course life form! Project Usagi!" Kirryu would say to the creature infront of him, who stared blankly at its creator.

As it focused on Kirryu, judging him...

"You will help me, you magnificent being!" Kirryu says as he goes to stroke his creation but suddenly Kirryu felt a searing pain as blood gushed.

The scientist's eyes widened in shock, confusion and horror! When he realized his left hand had been bitten off by the creature.

The child had swallowed Kirryu's left hand.

Kiryyu saw the child's eyes glow red with murderous intent.

"Wh-What!? Stop!!" Kirryu yelled holding the missing stump of his hand.

The child would proceed to leap so fast at Kirryu that the scientist barely had enough time to react as it sank its teeth into Kirryu's neck. Making the scientist scream. The monster child was drinking Kirryu's blood.

"AAAHHH!! ST-STOP I COMMAND YOU TO STOP!" Kirryuu yelled as he used whatever strength he could to push the child off of him.

His face was full of fear, he didn't understand? Why is his creation turning against him!?.

"I command you to obey me! I made you!" Kirryu says backing away to the lab doors.

The monster child glared. As it ignored kirryu's pleas and commands. As it narrowed its eyes.

Kirryu not wanting to risk getting killed by his creation he ran out the lab running down a corridor as he hit the alarm button.

As the alarm blared all throughout the Nomad facility. As multiple drones, cyborgs and Nomad soldiers would make themselves known.

"Don't kill the asset! It must not escape! Tranq it!" Kirryu yelled. He didn't want to destroy his perfect creation he needed to control it! By implanting a control chip into its brain to obey him! Where could this have gone wrong!?

But he knows he may have to destroy it should Edwin Black find out about the monster's existence and that its a relation to him.

The monster is basically Edwin Black's son in a way if the creature has his cells. Fused with Kuroi's own cells possibly making the child his son and heir.

The monster ripped the doors down with its demonic aura which seemed to destroy everything in its path.

"There's the target! This is alpha team leader we have the target closing in!" Says a Nomad Squad leader as there was a count of 12 Nomad soldiers aiming their guns at the rabbit boy who stared at them.

"Set to stun. Ready? Fire!" The Alpha leader says as his men fired their tranq darts at the monster who immediately froze the darts in midair with its demonic aura. As it redirected them at the soldiers who were tranqued.

Drones with turret guns flew in and started shooting at the Monster rabbit child. Only for no bullets to have no effect on it. As it raises its hand and blasts a laser beam destroying the drones.

More Nomad soldiers came in with more guns. 3 teams surrounded it as they looked ready to take aim and fire. But the Rabbit unleashed its Insanity Inducing Aura upon the soldiers. Immediately effecting their minds making them have vivid hallucinations and making them insane as they would shoot each other instead of the rabbit.

Kirryu who was watching this on his camera watched in horror and amazement at the sheer power the monster is displaying.

The monster rabbit child opened its mouth, and emits a charging lazer beam and would seem release in a corridor destroying more soldiers, drones, and caused large amounts of damage in the facility. Causing fires and explosions to spread.

The Rabbit seeing the destruction it made, would teleport away.

Meanwhile Kirryu watched everything on the camera as he saw his creation teleport... he failed to contain it... he failed to keep it under his control... and he definitely failed to destroy it...

Just what on earth... did he create...

He glanced at the missing stump of his left hand that the creature consumed.. he would suddenly grow tentacles to replace his hand.

This is bad... he must delete All security footage of Project Usagi, along with its creation and birth. Including the file he was in progress of making. He can secretly hide the dna of Edwin Black, unfortunately he ran out of the incubus king's blood he only took a sample of it just to fuse with project Usagi.

He can't afford having Edwin Black's right hand woman Ingrid sniff her noise in things that shouldn't concern her, the last thing he needs is for her to know he's secretly plotting to betray Edwin Black.

But now his creation is loose... and free!

What can he do? It needs to be destroyed or the very least contained so that he can could create another and this time he will install a control chip in its brain to ensure the next one doesn't turn on him.

Where could it be? Where did it go? It could be anywhere... Tokyo kingdom... Yomihara, the Dark World... maybe in japan... the human world... if possible the taimanins stronghold known as Gosha Village and destroy them all like it was destined to do.

"Damn it!" Kirryu growled in frustration at the huge fuck up and mess he have potentially caused.

A powerful bio weapon... uncontrolled... now free and will no doubt be a problem..

But:

If it its out free and have no loyalty to anyone. Plus it could be deemed as a threat by the other demon lord families in the dark world, they could potentially have a chance to kill project Usagi before it reaches its full potential. There's no telling how strong it will be, especially if it has the blood of both Edwin Black and Kuroi Ryuji.

Kirryu just hopes he hasn't doomed everyone including himself for trying to play god by making a powerful being.

There's no telling how Edwin Black or Kuroi would react to know they both have a spawn out there with their blood infused.

"But still... why? why did it reject me? Why did it turn on me? My creations have never turned on me before..." he says with a confused frown trying to think of what went wrong. What made it attack him?.

The evil scientist was thinking hard. Stroking his chin. Did the creature... not want to form a familiar bond with him?

Then it struck him... with his eyes widening realizing it. It needs to form a familiar bond with a closely genetic link.

He doubted the creature wants to form bonds with either of its "Father's" (Black and Kuroi). The creature's gnome is a Killer Rabbit.. and most baby rabbits rely on the closest thing they need more instead of their father.

It needs a:MOTHER.

"It wants a mother figure.. no wonder it rejected me.. but where in the hell will it get a mother? This strikes my curiosity..." He muses... this is beginning to make sense. He wondered how will it find a mother with a similar genetic trait like it?

He will send drones. Everywhere in secret to monitor his creation.

For now he will think about this later. He must erase and destroy any evidence relating to Project Usagi. Along with having some repairs done in the facility.. hopefully Ingrid or Oboro come to visit him to ask what happened down here. He'll just make a half truth and half lie that one of his bio weapons went rogue and that he had to destroy it.

(Yomihara)

The Bunny child teleported itself here... as it gazes around with its red eyes, glowing menacing.

The child now must look for food to feed it, since it consumed kirryu's hand.

After devouring the scientist's hand.. the bunny's intelligence and intellect had increased and grown. Absorbing kirryu's traits of being smart and clever.

The rabbit was naked he had no clothes on as he aimlessly walked off. Looking for a "Mother".

As he walked, he heard the sounds of fighting from his white rabbit ears that twitched. As he went to the source of it.

As he got there he spotted a lone woman that is fighting some orcs. This woman had moderate brown length hair, red eyes.. a curvaceous body, wide child bearing hips. A massive chest, a large ass, she held a polearm naginta. She wore a spandex like outfit which was her standard Taimanin outfit. He saw bunny ears standing from the top of her head.

His red eyes gleamed.. this woman... he sees is Mizuki Shiranui... the Water Taimanin.

She... is a suitable match for him... she's perfect...

He will go and bond with her.

(Shiranui's POV)

The water Taimanin would be cutting down demons and orcs seeing that there are so many surrounding her.

Before she could come up with a counter attack something happened.

The orcs and Demons began to disintegrate into piles of dust.

"What?" She spoke confused then her eyes fell on a lone bunny child... who was flaring heavy demonic aura and stared solely on her as its aura faded.

"Did this bunny child just rescue me? It looks so adorable..." She say mentally

"Hello? I thank you bunny child... do you have a name..?" She asked with the bunny staring at her as he raises both his arms.

"Mother..." It spoke for the first time. She blinked it called her mother? Why did it call her mother? This is not her child. Maybe it has her confused for it's mother.

"I'm not your mommy.. you adorable sweet thing. Are you lost? Are you looking for your mommy?" She says towards the child. She has a soft spot for children considering she has a daughter waiting for her.

"Mother..." it repeated again as it walked towards her and embraced around Mizuki Shiranui as something happened. A blinding light enveloped around the two.

It made physical contact with her. Shiranui felt a strong wave of its demonic aura run through her body.

The creature had successfully imprinted on Mizuki Shiranui as its Mother.

"What is this? This power? Surging through me? Why do i feel like my soul is connected to this child? Why do i feel the need to bond with it? " She thought not understanding any of these.

The creature had spread its demonic influence to travel through the woman's body to the brain.

Where it would influence her to see things his way from now on.

Shiranui had stared at the rabbit child with affection with a warm motherly expression.

"Hello.. my sweet cottontail.. what shall i name you?" She says picking the child up who smiled nuzzling his head into her massive chest as she stroked its head, its white hair and rabbit ears.

"How about i name you Izumo-kun?" She says seeing it shake its head in disapproval at the name.

"No? How about Shiro-kun?" She suggests. As the child seemed to like the name.

"Ok Shiro-Kun it is! What do you want to so Shiro?" She asked in her gentle motherly tone.

"H-Home.. let's go home..." he says.

"Okay darling lets go home! To gosha village! You'll like it there! Yukikaze might love having you as a little Brother!" Shiranui says as the two would go home to the village of taimanins. The bunny now named Shiro.. has bonded with Shiranui.. and will remain close to her, at all times to further influence her. He has so much planned for Shiranui...

to be continued

An: if i managed to do a Killer Rabbit x Kuroinu i can do the same with Taimanin!.

until next time!
