Prologue

"Are you sure about this?"

A tall man with short black hair asked with concern evident in his tone towards the figure walking right next to him.

"I am, Tsukauchi-san." The figure next to him replied with a confident tone. "I am interested in seeing this 'person'."

Tsukauchi nodded in response but he still couldn't help but be worried about the figure walking right next to him.

The figure next to him was a very large man with a muscular and well-defined physique. His hair was bright blonde and was styled brushed back with two distinct tuffs of hair sticking up resembling antennae or rabbit ears.

In their society, the huge man talking was someone who was standing at the top of their field.

The current number one professional hero.

The symbol of peace.

All Might.

"If what you're saying is true, then she could be someone who can give aid to us." All Might explained.

"We're not really sure if she is someone we can actually trust, you know." Tsukauchi stated trying to convince All Might from whatever idea he was planning inside his head.

"But you said that she wasn't resisting."

"That is true, but it could all be just a ploy to get us to lower our guard."

"Shouldn't you be able to tell whether she is telling the truth or not?"

"That's the thing." Naomasa interjected with a worried tone. "My quirk is not perfect. I know that the best than anyone. But it's something that helped not only me but my fellow officers in our line of work." Naomasa continued as both he and All Might finally reached a door at the end of the hallway.

The hallway they were walking through was clean and sleek. Rows of surveillance cameras and sensors were line up on the wall. The door at the very end of the hallway was heavy and metal with a biometric security scanner at the right side on the wall.

There were several rooms like this.

These kinds of rooms were exclusively made and reserved for people that were considered to be a huge risk towards peace and orders. The people who were held up in these rooms were criminals who did outrageous crimes and despicable deeds and villains who specifically used their quirks to disrupt the peace and innocent lives of civilians. Most villains who were kept here were designated as "Too dangerous to detain in regular cells."

"This really is an impressive design." All Might commented as he observed the details of the metallic door and biometric scanner.

"It is a must." Naomasa added as he pulled out a white keycard from his pockets and inserted it in the slot on the scanner. "From the kind of people that this kind of room was designed for, this was the absolute minimum measure regarding security."

"If I remember correctly, the one inside is just a young girl." All Might said with a slight frown appearing forming on his lips.

"Small girl or not, we had determined that she is to be treated as a great threat towards peace."

All Might trusted Naomasa for certain, but he couldn't help but feel that the police force had gone a bit overboard with how they were treating the small girl they had just managed to capture.

Sensing All Might's discomfort, Naomasa let out a sigh. "I know how you feel. Really, I do." Naomasa let out a small groan as he carefully took of his glove on his right hand and pressed his now-bare palm on the biometric scanner. "That is why though my designation should make me lean otherwise, I do hope that the girl is given a chance."

The scanner produced multiple kinds of sounds resembling beeps as it scanned Naomasa's palm for several seconds, The screen turned yellow from red.

Naomasa then put back his glove and bent forward a bit in order to have his eyes scanned by the scanner.

Like earlier, the scanner produced all kinds of sounds as it analyzed his eyes for several seconds. The screen then turned green from yellow and showed the picture of Naomasa on screen and the huge word 'cleared' right below blinking in and out. The door the produced a clanking sound before finally opening slowly with a huge thud.

"Normally, no regular person should be allowed here." Naomasa explained as he gestured All Might to enter in first. "Even professional heroes would have to through great lengths in order to be allowed. But since it's you we're talking about, we had decided to give what you plan a try."

"Thanks, friend."

"Don't thank me yet. We're not sure if everything will work out the way you want it to."

All Might entered through the door first before Naomasa followed him. As he entered, All Might noticed a number of figures sitting on chairs in front of a table that was laid out in front of a huge mirror conversing with one another.

One of the figures was a middle-aged man with dark gray hair and stern eyes with a seem to be permanent frown on his lips.

All Might knew who the man was. After all, being a professional hero ensured that he was to be able to meet the man atleast once in his work.

The man was the Commissioner General.

The highest rank in the police force.

The figure sitting beside him had the body of a very tall and sturdily built man, yet his head was that of a beagle. He was a man that All Might knew quite well.

This man was the chief of the police force, Kenji Tsuragamae.

"You've arrived." Kenji greeted the two with a slight bow.

"Yes." Naomasa nodded in response.

"I've come here for one purpose, my friends." All Might stated.

"Before that, come sit." The commissioner general commanded both All Might and Naomasa gesturing to the other seats.

Without any words, All Might and Naomasa made their way towards the table and proceeded to take a seat just right next to Kenji.

"I've already been briefed regarding on the matter." The commissioner general immediately began as soon as All Might and Naomasa took a seat. "I can't say that I agree completely, but it is worthy of consideration."

"Hmm." All Might nodded in understanding. "While I can understand your side to a certain extent sir, may I ask what exactly are the thoughts of the police force about the issue."

"Most of the members of the police force doesn't know about the existence of the girl, only a select few." The commissioner general explained. "While I dislike hiding the truth from my people, I do know that sometimes hiding some things are the only way to avoid panic and confusion."

"Why would awareness about the girl bring about panic?"

"Her strength, All Might." Kenji joined in the conversation. "I'm certain we already explained to you what happened on site?"

"Indeed, but.." All Might cupped his chin with his hand as he continued. "While I do believe the words of the police force, I'm having trouble imagining that such a small girl is capable of such things." He then turned his gaze to Naomasa Perhaps my imagination is not enough?"

"Whatever your imagining, All Might." Naomasa replied with a slightly grave tone. "Multiply it by tenfolds." He then shook his head as if disagree with his earlier words. "Multiplying by tenfold is just not enough."

"Have we learned anything new about the girl then?" All Might asked turning to the commissioner general and Kenji.

"Almost nothing." Kenji replied with a disappointed tone.

"Even with your quirk?" All Might asked Naomasa.

"As I stated earlier to you, my quirk is not perfect." Naomasa explained as he tapped his finger on the surface of the table in front of them. "However, perfect or not, I am confident in my skills in finding out atleast a few things from people."

"And?" All Might gestured Naomasa to continue.

"That's just it." Naomasa stated in a slightly depressed tone. "No matter how hard I tried, I just couldn't sense anything substanial from the girl." He grabbed his head with his hand as if to gently massage out the slight headache he was starting to feel. "It was as if the girl had absolute resistance towards my skill and quirk."

"So we don't know anything about the girl?"

"Just her name and a few things."

The commissioner general then slid a folder containing a document that stated what they found out about the girl across the table. All Might picked up the folder and opened it to read the document inside.

"There's barely anything here." All Might turned the page. "Except the girl's quirks?"

"We're not sure if she has multiple quirks or if it's just a single quirk that is flexible or able to do different things." Naomasa recalled.

All Might read the document in silence for a few minutes. While All Might read the file, commissioner general, Kenji, and Naomasa engaged in a conversation regarding the topic at hand.

"Can I see the girl now?"

Naomasa turned to the commissioner general to ask permission in which the man gave with a nod. Naomasa then walked up towards the long horizontal mirror and pressed a button just below its frame.

The dark mirror then began to glow from the light coming from the other side.

All Might stood up from his seat and slowly walked up towards the mirror in order to get a clearer view of who was inside. He scowled as he noticed what state the girl inside was in.

The girl was covered from neck to toe by a thick strap jacket that held her limbs tight in order to prevent her from moving her arms and legs. Metallic braces framed the girl's body over the strap jacket for more security. And as if everything wasn't enough, several chains were wrapped around the girl's body and was strongly secured by ring binders from the for corners of the room.

"Isn't this just excessive?" All Might complained. He disliked everything he saw. While such security measure were warranted for the most dangerous of criminals and villains, he found it very difficult to accept that such measures were used on such a small girl.

"We had to do it." Naomasa grimly replied.

"This is just wrong." All Might turned to Naomasa showing great anger on his face. "She's just a small girl!"

"You must understand! The girl is a great threa-"

"...It is fine."

Before Naomasa could even finish his sentence, a voice called out from the speaker located just underneath the mirror's frame.

"She can hear us?" All Might asked.

"No. That can't be possible." Naomasa's eyes were wide due to his shock. He turned around and saw both the commissioner general and the chief of police were shocked as well. "This is a two-way mirror. She shouldn't be able to see us nor hear us unless we press the speaker button located underneath the mirror's frame."

"Ahem." All Might thought it would be better for him to speak to the girl in order to ease up the uneasiness that radiated in the atmosphere inside the room. "Do you know who I am?" He asked trying to double check whether the girl could really hear them or not.

"...No." The girl replied in a monotone voice.

"I see." All Might smiled slightly. "For now, just know that I am someone that can help you in your current situation."

"...Help me?" The girl asked. "...I don't need it."

"Hahaha!" All Might couldn't help but chuckle at the girl's response. "Really now? Aren't you uncomfortable like that?"

The girl was silent for a few seconds before giving out a reply in the same monotone voice. "...I am."

"See!?" All Might smiled. "Now, if you cooperate with me and everything turns out okay, I can help you."

The girl gave no response.

"First, we must learn that we can trust you."

"...Trust me?"

"Yes."

The girl then fell silent for a few seconds again before giving out a reply. "...Isn't this enough?"

"Huh?" All Might narrowed his eyes to the girl's response unsure on what the girl meant. "What do you mean?"

Naomasa eyed the girl curiously.

"...Isn't this enough of a show of trust? Me staying still?" The girl stated referring to her bindings. "...I can get out these ordinary bindings quite easily."

"Haha!" All Might chuckled. Amused at the young girl's bluff. He found it quite funny that the girl referred to her bindings as 'ordinary'. "Surely you jest, young girl!"

Then as if to prove her point, the young girl tensed up her body slightly and began to exert her strength. The strap jacket's strong fabric then began to stretch and produce a ripping sound. While the metallic braces that framed her body and the chains wrapped around her began to shake and produce a distasteful crisp creaking sound.

All Might's eyes were wide due to his sheer shock while Naomasa pressed his hands up on the surface of the mirror unable to fully take in what was happening in his very eyes.

"Stop that at once!" The commissioner general bellowed out a command towards the girl.

Hearing the shout of the man, the girl ceased her actions and fell silent.

Naomasa and the commissioner general were both covered in cold sweat. Kenji stood up from his seat with a look of disbelief written all over his expression.

All Might stood there with a wry grin on his lips. He was still smiling, but deep down he felt something akin to fear. What he said earlier was true; his imagination was clearly not enough.

Looking at the girl whom was now fallen into complete silence looking like nothing in her current situation was wrong. As if the feat of strength she had just shown earlier was just child's play to her.

All Might swallowed nervously.

If the girl were to become an enemy, he was sure that she would be a dangerous threat towards their society.

He didn't want to compare the young girl to his former arch-nemesis, but he couldn't shake the feeling that if she were to become an enemy, she would be on par or atleast close to his arch-nemesis.

The girl produced that kind of feeling of dread.

Deep inside All Might grew very afraid yet also excited.

Due to her actions, All Might now understood that the girl's words were serious.

After all, the girl could actually break her bindings easily and escape, why would she stay? Perhaps she was trying to gain their trust?

Maybe, maybe not.

Who knows.

But what All Might was sure of was that he wanted to do everything he can to ensure the girl doesn't fall into the wrong side.

Strong or not.

The young girl was still a young girl.

All Might felt it was his responsibility to guide the young girl towards the correct path.

Thinking about teaching and guiding, All Might produced a chuckle. Such thoughts and feelings made him remember the young boy he had entrusted his power to.

They might get along. He thought.

All Might then walked up to the front of the center of the mirror and leaned in closer to get a better look of the girl.

She looked petite and delicate. Her facial features were exquisite and elegant, and even though she was wearing an eyepatch that covered one of her eye, it did not diminish her beauty in any way. Her hair was long and straight and had the color of red-gold.

The girl was so beautiful that it looked like she was a perfect doll that was artificially created by hand.

"Ahem." All Might produced a fake cough in order to clear his throat and also grab the girl's attention. "Try avoiding that kind of action again, alright?"

The girl gave no response.

"So, let's introduce ourselves, shall we?" All Might said even though he already knew what the girl's name was because of the document that was presented to him earlier. "What's your name?"

The girl was in complete silence for about almost a minute before finally parting her lips in order to give a reply.

"...Shizu Delta."

To be Continued.
