Spy At An All-Girls School!!

"Begin."

A man with green hair wearing a lab coat instructed as he was seen outside a huge white room, staring at a glass as he was on a microphone, serving as the only form of communication between him and the white room, in which two children are seen inside.

Inside the huge white room, both occupants heard the instruction as they comply without question. Both are also armed with a small knife as the child with messy blue hair now being seen in combat together with another child with black hair.

Both are shown to be wearing a small white gown like in those hospitals as they held against one another in equal footing, blades clashing with one another as both sides give it there all in the fight for their very survival.

But in the end, the blue-haired child proved to be the better combatant as he punched his opponent right at his cheeks, giving him a disfigured bruise as the black-haired child falls to the ground in exhaustion and pain.

"Now, finish him off."

The boy followed without question and as he was about to lunge the blade straight at the other child's c.h.e.s.t, the latter was now seen to be crying in fear.

"Please don't do this!! I don't want to die!! Why are we even doing this?! Why!!??" The black-haired child was all in tears as he shivered in terror and fear at the prospect of suffering a painful death.

The blue-haired boy hesitated for a moment as he withdraws his blade and held a sad look on his face as his hands trembled, feeling the same way.

"Gotcha~"

The blue-haired boy was caught in surprise as his opponent suddenly lunged towards him in his act of weakness, both now on the ground with the black-haired boy's own blade nearing dangerously at the former's throat.

"Didn't teacher tell us to not let our guard down at any moment Rin?" The child grinned in an atrocious manner, his demeanor wicked in every way as his only intent is to murder the blue-haired child right in front of him.

"You fooled me Drake." The young Rin felt betrayed.

"Oh don't blame me Rin buddy!! It is the survival of the fittest after all!! To show who is the one worthy of walking in the ranks of the Brotherhood!!" The black-haired child now named Drake cackled sadistically.

Rin looked in despair at the blade being forced at him as he struggled to break free from Drake's grasp.

"Yes Drake, I don't blame you indeed." Rin merely answered as he kicked Drake in retaliation, causing the latter to be knocked off on the floor.

Drake shrieks in pain at the rather brutal kick and he was not even given the chance for another movement as a knife sunk deep in his c.h.e.s.t, courtesy of Rin as blood spluttered tremendously on their white clothing.

Rin then heard a chuckle, mad-driven coming from the dying boy.

"Hehehe what a monster indeed." Were Drake's final words before he finally perished.

Rin could only look without any emotion at the now blood-stained dead body right in front of him.

"I don't blame you Drake." Rin said with a voice devoid of any feelings, his crimson red eyes filled with disgust. "I only blame myself for trusting you in the first place.

After the sick scenery finally made its conclusion, the man's voice from the outside was sounded for Rin to hear.

"Outstanding work Agent. Please proceed to your room and wait for further instructions."

Rin only nodded in response as he made his leave on a nearby door that was now unlocked.

The green-haired man then released himself from the microphone and assumed a sinister smile.

"Fascinating, truly Remarkable. Aside from the subject's initial hesitance, he displayed no signs of turmoil and delay when landing the killing blow."

A woman suddenly joined him, her face and figure masked and concealed by the shadows of the room. "How's the subject going?"

"A true Agent in the making ma'am. With him and the girl, we could produce the very best duo that the brotherhood has ever offered, all for the glory of the Kingdom!!" The man said like a blind devotee willing to devote everything for the cause.

"Good, it seems that the Children Initiative is a success. Keep up the good work, Serpent."

<Present time>

Rin Grayson could only witness at utter disbelief at the female figure wearing the Brotherhood's Covert Suit right in his very eyes.

The boy then turned to face the butler Wilfred Heimstern, concern about the old man's well being. Instead of finding the man cowering in fear and showing signs of distress, Wilfred was in fact showing extreme calm and tranquility in the midst of danger as hinted by his passive expression despite the fact that a seemingly unknown person wearing a Catsuit is shown to be in front of them armed and ready to use her weapon.

Like he knew that all of this was supposed to happen.

Rin assumed a suspicious expression. "It seems that you know what is going on old man. Care to enlighten me with the situation?"

Wilfred chuckled in response, amused by the boy's sour look directing right at him. "I assure that we mean no harm to you Ms. Rina Mayfield or perhaps Rin Grayson is what you prefer that we call you, Ant of the Brotherhood?"

Him hearing his true name and code name in a single sentence seemed to have answered all of his questions, cl.i.c.k.i.n.g his tongue in annoyance as he finds this situation very troublesome.

With a sharp glare in his red crimson eyes, the boy undercover as a female student stood up straight as he turned his head to face his adversary without a shred of fear. "What's the meaning of this?! I'm not sure what scheme you are playing at fellow sister of the Brotherhood. I had enough of a certain Tiger who has done that to me a few days ago and if you won't stand down and unsheathe that weapon of yours then I'm not sure if you will leave here unscathed."

As befitting of a true Agent in the shadows, Rin received only silence in response, the female Agent showing to be very professional as she gazed the blue-haired boy like his soul is being peered without permission.

"The Silent treatment I see." Rin nodded to her credit, crossing his arms. "You have been trained well indeed, but-"

"-As they say..." Without warning, Rin grabbed a nearby wooden chair from his side as he immediately threw the object straight right at the Agent. "Action speaks louder than words!!!"

Of course, the Agent managed to dodge quickly, maneuvering herself to the side as she closed in the distance at the blue-haired boy. The Agent then slashed the dagger in a sideway motion as it was accompanied by the sheer force of the wind behind it. Of course also an Agent himself, Rin easily dodge the attack like it was as natural as breathing, his combat instincts kicking in as he eyed the deadly small blade directed at him.

"You're quick I can give you that." Rin said as he praised the Agent's abilities. The boy was not allowed any further room for idle as the Agent continued her assault, every slashes offering no wasted movement and rhythm. Being one without arms, Rin could only twitch in annoyance as he retreated a few paces away. "Wow, this could have been fair if you give me a weapon too you know."

And once again no answer as the Agent dashed forth to his direction and slashed in a diagonal arc. Rin retaliated by moving away from the attack at a side motion as he gritted his teeth at the quick movement.

Expecting such movement on her part, the Agent smirked in triumphant behind her mask, immediately grabbing the boy much to the latter's surprise as the former locked the boy firmly on her grasp, both of their bodies pressing against one another with the dagger now positioning on Rin's throat.

"Submit, or else...." The Agent finally spoke, revealing her captivating female voice as it expressed a demanding and angry tone for the boy to hear.

And the rage behind her voice was not gone unnoticed by Rin as he raised one of his eyebrows subtlety with interest.

While the Agent thought that she has finally achieved her sweet taste of victory over this deviant cross-dressing pervert who saved the princess and instead of her, she failed to notice the sly smirk coming in from the boy's feminine face.

"You know sister…" Rin said, his voice sounding… intrigued much to the Agent's confusion. "You really are impressive, managing to put me in this rather compromising situation. Although, I feel the anger in you, I wonder what riled you up so much that putting a knife on a brother's throat takes precedence over our oath of camaraderie as a Brotherhood?"

The Agent gritted her teeth under her mask, seething in frustration at not wanting to hear anymore of what the boy is going to say. "I say submit!! or-"

Emotions riling up, Rin utilized the Agent's rage against her, the Agent being at lapse as Rin skillfully turning his body in a quick motion and following up quickly with a punch right at the Agent's gut, causing the Agent to be disoriented with the massive amount of pain as oxygen temporarily left her lungs. Rin then charged right at her, leaving her no room for comfort as he choked the Agent's neck and slammed her body against the office desk right in front of them, causing it to break apart violently.

The Agent g.r.o.a.n.e.d in pain and frustration at the rather underhanded and brutal display of the boy as she was on the floor in her c.h.e.s.t, catching up her breath profusely from the punch earlier. Before she could even devise a counterattack of her own, her weapon was used against her, the dagger pointing straight at mere millimeters on the back of her neck as he poked it slowly to emphasize the feeling of a slight prick of the weapon while being pinned down to the floor as the boy twisted and locked her right arm without care by using his right foot.

"If you are distracted by mere pathetic emotions and grudges for whatever unknown reasons direct right at me, Agent, then perhaps you still need more training. This is quite a bore and frankly, a dissapointment." Rin said with an unamused but c.o.c.ky tone, proving to be the superior Agent at the end as he only felt displeased by the performance of his fellow Agent.

The Agent could only grit her teeth in pain as she was being step and trampled on the ground by some perverted guy in a drag.

"Now tell me what the f.u.c.k is really going on or I assure you with no traces of bullshit, your arm will be the least of your concern when I'm through with you."

The boy continued his torture by burying his foot even deeper on the Agent's shoulders, the latter now shrieking in utter agony and torment.

The Agent could not believe that this was all happening. To think that a boy with a small, girlish frame would overpower her in an instant. The strength behind his punch is so much overwhelming that she exerted every ounce of her willpower to the fullest to not faint at the very spot. Then his brutal assaults did not stop there as he pushed her to the desk with so much force that it was torn apart!!

Heck, even Wilfred, the butler standing behind them from a considerable distance could only stare at Rin with awe and to be honest, a bit of fear at how savage and ferocious the way that the blue-haired boy acted on the Agent.

Then her eyes widen as she remembered what her superiors gossips in the Brotherhood.

An Agent situating at the Dawn Branch, with a success rate of 99.8% in his mission reports. A young boy, 15 years of age, trained within the Brotherhood ever since he was a child recruited from the orphanage. One of the two survivors of the Children Initiative, the other being a young girl of the same age known as Chameleon.

How he handled every mission, every job with extreme and brutal efficiency, sparing no expense, no risk, no excuses.

How he ended the lives of his adversaries without a single shred of care, his eyes straight only to the completion of the mission itself, no matter the cost.

Although he has mellowed throughout the years ever since in a particular mission that caused him to be missing in action for a whole year, his performance and skill set as an Agent of the B.S.S. did not diminish even a single bit.

Wielding a katana as he sliced and diced every single foe in his vicinity, he is one of the most feared Agents throughout the entire Brotherhood.

The Agent who goes by the sole code name of-

"Ant." The Agent muttered in fear at the one who overpowered her. "It seems that the rumors about you are true. How you shamed and forced me in this awkward position… How ruthless."

"So you know about me." Rin said, his voice still passive. "Why did you attack me then after knowing that you are of no match to me."

"Because I want to confirm if what the rumors circulating about you in the Brotherhood are indeed true." The Agent answered. "Not many are willing to work with you as you mostly work alone in your every mission and I want to confirm your combat capabilities with my very eyes."

Before Rin could come up with a reply, a familiar female voice was heard in the room, causing all of the occupant's eyes to widen.

"I believe that's quite enough~"

On cue, a petite girl suddenly appeared from the sides, her cute face smirking in a sly manner at the scene right in front of her.

All eyes turned their attention at the newcomer and boy, the socket on Rin's eyes threaten to pop out right at this very moment upon laying his crimson red eyes on the girl's similarly colored eyes.

"Hello Agent Ant. I must say, I'm very glad that you are now well and healthy after a week of recuperation. If you don't mind, would you kindly release the poor dear girl who is currently suffering from your grasp?"

Rin nodded absent-mindlessly, immediately complying the orders of the girl in front of him without question.

"Of course, Princess."

The silver-haired girl with the beret cap smiled deviously as she eyed one of her three saviors with intrigued.
