A/N: A simple idea that came to me a few days ago and I wanted to try fleshing it out a bit. Also, I haven't written an OC for the BNHA franchise yet so I wanted to experience in that as well :)

I have no major plans for how many chapters this will end up, so for now I'll just roll with it.

~Chapter 1~


"Arisu?"

Her green eyes fluttered open to the sound of her name coming out of the phone she held next to her ear. Then, she lifted her free hand to move her wavy cherry-brown hair away from her face, letting out a loud grunt.

"It's too early, Sumi.." She muttered as she pressed the speaker button on the screen, then dropped the device to lay on the mattress right next to her head, turning away from it on her left side and snuggling deeper into her soft blanket.

"Wake up already, you've got an analysis to do today." The voice called impatiently.

Hearing those words, the young woman simply turned back to face the device.

"Where." She demanded, already preparing herself for an answer that would surely annoy her.

"Relax." The voice reassured, "I don't really know all of the details, but people are talking about you really lucking out this time!"

Her green eyes opened slightly as she simply stared at her phone next to her, processing the information.

"Well, I'm not agreeing to anything unless I know where the analysis is located, do I really need to remind you –" She started, only to be suddenly cut by the voice;

"Yes, yes, last time they assigned you to a really shitty place and only 5 outta the 50 you've examined passed as potential Hero material."

Her green eyes narrowed with displeasure.

"They always give me the absolute worst locations, I'm sick of it." She complained, rising into a sitting position on her bed, her long, messy cherry-brown hair falling down from the bun she had set it in before going to sleep.

"That's because they know you can handle it." The voice encouraged, "Besides, it's not like you can actually turn down an assignment, you know. Some places are just shitty. It's part of the job to-"

"-Sort out the good from the bad, I know." She dryly cut into the sentence, "That still doesn't have anything to do with the fact that I keep getting royally screwed over. Maybe I should just quit this job."

Checking the time, the young woman simply yawned loudly, then raised a hand to scratch her head.

"Good, that sounds like you're finally getting up." The voice said with amusement.

"Shut up." She hissed as she reached out and picked up the device once again, "I'll be at the office in about an hour, so I'll talk to you later or something."

And with that, she ended the call.

Moving to sit on the edge of her bed, she rubbed her tired eyes as she opened her phone's lock screen, noticing a large notification alerting her of her new assignment.

Reluctantly pressing on it, the E-mail opened before her as she stared down at it with a skeptic expression.

To: Arisu Kasai

From: Assessment Department.

Subject: New Analysis Assignment! Please report to the office immediately.

She let out a loud sigh, then scrolled down to the end of the E-mail, closing her phone as her expression became irritated.

"As always, no details until I actually arrive there myself to find out, huh." She muttered to herself, standing up and walking to her bathroom to start getting ready for her day.


Exiting the cab right in front of the Assessment Department office building, Arisu simply stood in her place and stared up at it for a few moments in silence. She narrowed her green eyes which were hidden behind her black, square sunglasses as she tucked her hands into the pockets of her long, dark grey jacket. Her cherry-brown hair was wild behind her, the wind flowing through it occasionally sending it to block her field of vision and only making her all the more annoyed with the situation.

'Pray for a good location.' She thought to herself, letting out a sigh.

Then, she stepped forward and through the large glass doors, entering the building.

But before she could even make it to the elevators, she was stopped by one of her co-workers as his eyes quickly spotted her, his expression turning excited.

"Yo! Who did you bribe to get an assignment like that, huh?" He jokingly shot at her as he followed in her footsteps, quickly catching up and walking beside her.

Arisu simply lifted her sunglasses to rest on the top of her head, then stared at him for a few moments in silence.

"I know, right?" She finally answered, watching him closely as they both made their way to the elevators, "Too bad I have no idea how to get there."

Her male co-worker simply stared at her, wide eyed.

"What do you mean you don't know how to get there? Everyone knows where U.A Academy is located." He stated, visibly suprised.

Her green eyes narrowed at his words.

'U.A Academy, huh? that super-prestigious famous high school located at the center of the city?' She thought to herself, continuing her staring at her co-worker for a few more moments, 'At least it's not a shitty place, but why would they assign me there? Those guys never asked for an analysis on a student before since they have such high quality teachers and admission requirements.'

"Why are you looking at me like that?" He suddenly asked, successfully breaking her thought process.

She shook her head.

"No reason. Thanks for that, though." She answered, entering the elevator while pressing the button for the 20th floor, her co-worker's confused face quickly disappearing behind the elevator doors as he stayed behind her, but not before she caught the sudden glimpse of realization in his eyes, making her shoot him with a victory smirk and a wink seconds before the metal substance separated them both.

"What the- again?! ARISU!" She heard him yell at the closed doors as her elevator began moving up.

'Alright, figuring out where the hell they assigned me to – check.' She mentally noted, shifting her green eyes up to watch the monitor as it displayed the number of floors left, 'Now I just need to know what to expect. I'm not even sure who exactly teaches there.'

But just as she finished that thought, her elevator suddenly stopped at the 15th floor, opening up to reveal two more female co-workers.

'Shit.' She cursed to herself, understanding she'd now have to share this tight space with another human being. Make that two, actually.

"Arisu!" One of them called as she noticed her presence as they both quickly stepped into the machine, "What a surprise to see you here! You're barely at the office with all the assignments they give you, ahaha." She called, smiling.

"Yup, busy me." Arisu answered, leaning against the wall behind her, "I suppose you guys heard about my latest one as well?"

The other co-worker suddenly beamed.

"Of course! Everyone's talking about it, being able to enter that super prestigious school and meet actual, famous Heroes!" She answered excitedly.

'It's too early to fangirl this much, and I have no idea who she's talking about.' She thought to herself, annoyed.

"Oh yeah, that guy's teaching there, isn't he? Forgot his name." She asked, watching them both closely.

"All Might!" One of them called.

"And EraserHead! Not to mention Present Mic and Midnight!" The other one squealed, "Not even the media is allowed in there so up until recently we didn't even know about the staff's true identities! They're so super secretive about how they run that place."

Arisu simply stared at them both as she took a moment to process the information.

'Figuring out what to expect there - partially check.' she noted to herself, once again.

"You guys sure know your stuff." She gave them a pleased smile, lifting her green eyes to the monitor once again as she noticed the elevator had finally reached her designated floor, "Well, see you both later."

As the doors opened, she simply stepped out in the direction of the main office, stopping right next to the assistant desk, where her friend was working.

"Hey, I'm here." She told the young, black haired woman sitting, making her lift her golden eyes up to her.

"Arisu!" She called, wearing an amused smile on her face, "Glad to see you haven't quit this job yet."

Arisu simply shot her back with a sardonic one.

"In time, Sumi, don't worry. For now, I do need the money." She answered, crossing her hands down at her friend's direction, who simply eyed her quietly for a few moments.

"Sure, not like you secretly like this job or anything." The assistant said confidently, lowering her gaze back to her work.

Arisu simply pouted her lips.

"Whatever." She muttered, her expression turning slightly displeased.

"Anyway, he's actually free now, so you can enter." Sumi said, pointing at the door to the boss' office unsing the pen in her hand.

Arisu blinked and stepped to the large glass door, then opened it, entering the luxurious office as she made eye contact with her boss, who was sitting at his desk and looking through some paperwork.

"Ah! Good to see you, have a sit, Arisu." He called to her with a smile, gesturing towards one of the black leather chairs in the room located before his desk.

She complied and sat down, watching him closely as she kept silent.

"Now about your assignment this time, the location is –" He started, only to get cut by her words.

"U.A Academy, I know." She said, her green eyes fixed on him, "Why there, though?"

His expression turned surprised at her sudden words.

"I see you've managed to figure out the location on your own once again.." He chuckled, a pleased smile spreading on his face. "However, the reason for you being assigned to that place is far more confidential, I'm afraid."

Arisu's green eyes narrowed at him.

"Tell me." She said, leaning back in her chair.

Her boss cleared his throat, then shifted in his far larger, black chair as his expression turned serious.

'Sweating, stern expression, mouth solemn. Haven't seen him like this for a while, what's he getting all worked up for.' She thought to herself, raising her right hand to support the side of her face as her green eyes were left fixed at the man sitting before her.

"We've chosen you specifically for this one because we all know that you're one of our sharpest analyzers despite being so young." He started, watching her closely, "After dealing with countless troublesome cases of Hero Assessments we now need you to pay close attention to any kind of abnormal behavior while you're there."

Her expression turned confused at his words.

"What do you mean, 'abnormal'?" She asked him.

The man took a deep breath.

"U.A Academy's headmaster had contacted us regarding a possible traitor living among them." He explained.

Arisu's green eyes widened.

"A traitor? What, like in the movies?" She asked, trying to hide the mockery in her voice as she raised an eyebrow.

"This all sounds far-fetched, I agree, but given the latest news about how U.A keeps being attacked by the Villains, his worries may actually be true." He said, leaning backwards, opening up one of the drawers in his desk and pulling out what seemed to be a large-cased document out of it, "These are the names of every student in the first year heroic department, the same one that had been attacked not so long ago while being out on a training trip." He then quickly handed her the file.

Arisu took it from his hands, staring down at it for a few moments in silence.

"I want you to go over all of their names, faces and backgrounds, see if you can link anything together before you go there physically to have your regular assessment."

Lifting her gaze back to him, her expression once again shifted to a puzzled one.

"Shouldn't they involve the police about this, though?" She asked, lifting her right hand to scratch her head.

Her boss cleared his throat, once again.

"The police is already involved. I'm guessing the headmaster is taking every means necessary in order to solve this problem, and that includes using our special department." He explained, "You'll arrive there under regular terms and provide regular analysis and assessment for each of the students, just like you've been doing up until now, but I need you to be very alert to anything out of the ordinary about them."

'What is this, a Hollywood thriller film?' She thought to herself, silently staring at him as he continued;

"Do you understand what you need to do?"

She simply continued her staring for a few moments in silence.

"Sure. I'll do it." She answered, shrugging.

'I'm definitely not getting paid enough for this, though.'

Her boss let out a loud breath at her approval.

"Good." He said, leaning back in his chair. "Take the rest of the day off today and read that document. Tomorrow I want you to arrive there first thing in the morning and begin working, it's already been settled with the teachers."

Her brow furrowed at his words.

'They've already settled it without even asking me first. Splendid.' She sarcastically thought to herself, her grip on the document tightening as she wore a fake peaceful smile on her face.

"Well, that was a long talk." She said, rising to her feet, "If you'll excuse me, sir, I need lots of coffee."

But just as she started stepping to the door–

"One more thing, Arisu." He said, making her stop in her place and partially turn in his direction, "The students themselves know nothing about this 'traitor theory', remember that and act accordingly."

She simply nodded, lifting her free hand to her sunglasses on top of her head as she lowered them down back to her face.

"Sure thing."

'Something tells me this assignment is gonna be a real pain in the ass.' She thought to herself, finally exiting his office.


A/N: A bit short, but I wanted to end it where it did.

Also some info on Arisu - She will have no quirk. Her job is supposed to be more on the psychological side, where she assesses young people's mentality before they turn into Heroes, considering anyone in this universe can one day decide to go evil and crazy with power.

Reviews are highly appreciated! :)
