An massive aura filled with bloodlust can be sense at the small girl who was instilling an peculiar strength within her, her trump card. However, her hidden power is like an double-edge sword, not perfectly made.

Sensing this aura, the three vampire nobles backed away from Guren. Keeping a safe distance away from the unknown which is the little girl.

"Are you...Shiro?" a soft voice asked as the black haired boy walked up to the albino haired girl.

Yuu stretched his hand to grab her shoulder, but then he was instantly electrocuted from attempting to touch Shiro. He flew away from her as Kimizuki grabbed his back.

"You okay, Yuu?" the pink teenage asked with concern laced in his voice.

"Shiro...that's not her." Yuu muttered.

Slowly but surely, she walked towards the Lieutenant Colonel who was slumped on the floor, wounded.

"May I ask you...are you my master?"

Ichinose Guren, who was unable to speak, due to see this sinister form of Shiro. He was bewildered by the little girl in front of him, he was caught off guard. However, time was ticking so he gritted his teeth and yelled.

"Yeah! I'm you're master, Shiro." he says as the albino haired girl kneeled down in front of the wounded man.

"What is your order, master?" she says with politeness and sense of duty.

"Exterminate the all of the three vampire nobles in front of you, right here, right now!" he ordered.

Bowing her head, in sign of respect. She complied to his order.

"Yes, my Lord." Shiro says before standing up and turning to the vampires.

The three of them made an eye contact with her as they felt shiver run up to their spines, not knowing the reason why they would be afraid of this human girl in front of them.

"Eck! She's so creepy!" Chess shrieked while cupping both of her cheeks in her hands.

"W-Where is she getting...this amount of b-bloodlust from?" Horn stuttered.

The two of them heard the sound of the sword being removed from its casing, they turned around and saw a furious Crowley who was gripping his sword rather harshly.

"You two, get back!" he ordered as the two complied to his order.

Crowley thrusted his sword towards the girl while having a safe distance away from her. "Let's see how strong you are, little one~"

In a blink of an eye, Shiro was already in front of the vampire. His eyes widened from when did she did that.

'When did she...?!' he thought as he was dazed and confused.

The ripping of flesh and fabric pierced the air as everyone who was watching, widened their eyes from the scene that just happened in front of them.

"W-What just...happened?" Crowley spoke as he spat crimson blood out of his mouth, it dropped on the ground.

Everything happened so past that no one was able to speak, especially Chess and Horn who was utterly speechless and out of words.

"I...feel so...cold."

The red haired vampire with dyed black looked down and saw his chest had an hole on it, but what surprised him the most was...it was empty.

His heart was taken away by the killer.

"N-No way...Crowley-sama!" Chess cried as she fell on her knees while Horn stood there, shocked.

Crowley turned around and saw the girl with a sinister smirk playing on her lips, then his eyes widened when he found out that his heart was held captive in her palm.

"G-Give my...heart back!" he yelled as coldness crept up to his veins, while his skin was turning paler from the lost of blood oozing out of him.

His vision becomes darkened as he tried to reach for his heart in her hand that was filled of grease blood that could make anyone's body go cold.

"Give it...back..." he fell on the floor while trying to reach out for his heart, Shiro squatted down and placed his ripped heart on his palm.

Blood streamed down her hand as she turned around and glared at the blue haired vampire who flinched before she spoke. "Who's next?"

"You're the one whose next!" Horn yelled as she turned around and saw the blonde vampire pointing an blade near Guren's neck, her hostage.

"Master!" Shiro yelled.

"Don't move! Or else...I'll kill this man right here and right now!" Horn yelled desperately as she holds the wounded Guren.

Everyone was silenced as they heard an helicopter's engine machine pierced the air, Shinya turned around and gritted his teeth.

"This is bad, the reinforcements are closing in..." he says.

"Shiro, my servant...listen to me closely, I will not repeat myself." Guren said loud and clearly, making the albino haired girl turned to him.

"Exterminate the vampires, quickly!"

Shiro's aura grew more larger from his commandment, she nodded. "You don't have to repeat it, I know."

She took a huge step ahead as she cut through the wind, thrusting both of her hands to the enemy as the blonde shrieked, obviously scared.

"Don't be fooled, they're using you!"

Her eyes widened as she halted after hearing a voice rung in her head, however, it was clearly from the unknown.

'A voice...?' the albino haired girl thought as cold sweat trickled down her forhead.

"I don't want you to fight anymore...please, stop it."

A loud voice inserted in her head as she could feel the sense of dizziness, then she lifted her head as her eyesight was slowly getting darker.

'Who is this...speaking?' she thought.

"Shiro!" she snapped back to reality as she saw a glimpse of red attacking her, then someone came and blocked the movement of the blade.

"Don't lose focus while we're still in war, you wanna die?!" Yuu yelled as he blocked Crowley's blade.

"Yuu...!" she exclaimed as the vampire swung once again his sword as they were sent back.

Her eyes landed on the vampire in front of her, it was the supposed to be dead, Crowley Eusford.

"W-Why...?!" she says, in the verge of tearing up. Suddenly, she forgot something crucial in killing a vampire.

In order to kill a vampire is you have to crush it's head, completely.

Forgetting this crucial rule, she failed to exterminate her target. Crowley surely noticed that somehow Shiro's bloodlust is blunted by something or someone who is clearly unknown.

"I've decided, I will kill you. Right here, right now." he says with an menacing aura.

"Kill me if you can." Shiro says as she readied her stance to go in for a kill once again.

"Don't get so cocky, you measly human!" he roared as he sprinted and hit his blade against her who blocked it with her hands.

They attacked each other multiple times as both gets damaged, but Crowley was the one whose been damaged even more than her.

'How could this be...? Knowing Shiro, she could kill those two vampires in a flash with her bloodlust. But somehow, it backfired.' Guren thought as he watched the two fight.

He came to realise something after thinking for sometime now, 'Could it be...the girl from Kureto's laboratory?'

An image of a specific girl flashed in his head as it was all clear to him now.

"Shiro! Revert back!" Guren yelled.

The bloodlust completely ceased from the little girl as the darkness escaped her eyes, leaving only light.

"I'm sorry, Mirai...I couldn't keep our promise..." she muttered before falling in complete darkness.

A dazzling light came out of her body as the vampires were slowly burning by the peculiar light, so they've quietly retreated, with Guren as their hostage.
