MHA x Kirigiri!Reader x BSD

The lavender haired girl was currently walking around Yokohama to go to her current workplace, The Armed Detective Agency. The teen has no special ability, she is just super intelligent. She's one of the most respected members along with Ranpo. Both Ranpo and the girl get along well despite the girl being one of the most stoic member of the agency. And that they had no special ability or a quirk.

The teen had a meeting with the President. Yukichi Fukuzawa is his name.

When she got to the café that was right under the agency, Ranpo and Yosano was together having drinks, snacks, and sweets.

"Good morning, Ranpo and Yosano." She greeted them.

"Hello Kirigiri-chan, morning!" They said.

"I have a meeting with the boss, see you later." The light haired girl said, while grabbing a cup of coffee. Payed the kind waitress for the drink, the woman nodding her head in thanks at the young detective.

"Ok, good luck! See you later." The dark haired girl replied. Ranpo hums and waved his hand with his signature closed-eye smile.

The girl is known as one of the three of the agency's sharpest detectives. Along with Ranpo and Dazai. She was currently on the elevator going up to the main detective building that was above Café Uzumaki. Sipping on the coffee ,while the elevator was going up, her eyes closed.

"Y/n-chan!" Dazai cheered as soon as he saw her in his view. He wrapped her in his arms for a bear hug.

"Oi! Dazai! Get back to writing your report and stop bothering her!" Kunikida yelled at the brunet. He stomped over to where they are and yanked Dazai off of her, throwing him somewhere. His voice turned softer, "Are you alright, Kirigiri-san?"

"Yes. Thanks. Kunikida." She bowed to him. "Also, just call me Y/n, we're friends after all." She had a small smile on her face.

"Alright, Y/n-san." He says. "Where are you headed to?" 

She says seriously, "The boss scheduled me a meeting with him. I should go now. Bye, Kunikida."

She left Kunikida alone with Dazai, who he was forced to deal with for the rest of the day.

She was alone to he thoughts when she was traveling to the boss's office.

'I wonder what the boss called me here for. But, realistically speaking he wants me to do another solo mission.'

She was now in front of the boss's door. She knocked. Entering when she heard the boss say that she can come in, closing the door behind her with her foot. Sitting down in the chair that was facing the notorious boss of the detective agency. She was familiar with this place having been in her countless of times for solo missions that was given to her by the man that was sitting in front of her. She's also familiar with the man before her as well.

"Good Morning, Fukuzawa."

"Good Morning, Y/n."

"So what did you call me here for? Another solo mission, I hope?"

Staring at her with pride in his eyes, he said, "actually, yes, but this won't be your normal mission."

Her eyes sparkled with interest for a moment. "Really? Why's that?"

"This mission will take place at a school that's in Musufatsu, Japan."

"Do you have a file for this mission?"

"Yes, here you go." Handed her a file with a letter that was inside.

Taking the file, she reached for the letter first in it was the letter that was directly from the principal.

This is what the letter said:

Dear Yukichi Fukuzawa,

I heard some amazing things about your detective agency, from a friend of mine that is also detective, and he said that this might be a good idea to have a few second opinions on some problems that we have at UA. My staff and I are afraid of these group of villains that call themselves the League of Villains have an inside of sorts inside of UA and I am requesting you to find who they are. I will gladly let Y/n Kirigiri into UA to see if this rumor is true or not. I am requesting this because of the villains leader, Shigaraki, got into UA for some files. Please understand that this urgent but at the same time we must be careful. Kirigiri would be a good asset for UA to have to find this traitor quickly. She will observe the main class that we have here along with a few other classes. She'll also partake in these classes to fit in and not risk any suspicion to her for the traitor to suspect her of solving this. However, if she doesn't want to partake in any of the classes that is also alright. The villains had planned to kill All Might and we don't want that to happen. The fate of the world is resting in her hands.

 Sincerely,

Principal Nezu

Here's my phone number incase she's interested: ###-###-###

——————————————————————————-

"UA, huh? Seems interesting enough for me." 

 "So do you want to call him then?"

"Sure." She picked up her phone to call him about this case.

(In Musfatsu)

Principal Nezu was currently in a meeting with heroes and a detective. The detective was still talking about the armed detective agency and Y/n Kirigiri.

Ring! Ring! Ring!

Voice on the phone: Unsaved number calling! Want to pick up to answer?

Ri-

"Oh, sorry. This could be important." Nezu says picking up his phone.

"Hello, who's this?" He questioned the person.

"Hello, Principal Nezu. It's me...Y/n Kirigiri."

"Oh, hello! Kirigiri how may I assist you?"

"I called to say that I will take the mission you requested me to fill."

"Really? That's wonderful!"

"Yes, it is. So, are you going to send me anything like a uniform or something."

"I will allow you to wear whatever you would like to wear. You will go to UA tomorrow, when you get there go straight to my office"

"Ok. Sorry, I got to go now. It was nice talking to you."

"Alright, bye then Kirigiri. It was nice talking to you as well."

"Bye." She said than she hung up.

"I do hope she solves who the traitor is before the traitor turns themselves in." A hero says.

"Agreed." Another one says.

"Personally, I think that she is just the right person to solve this." The detective, Naomasa Tsukauchi said in response.

"Detective, why do you have so much faith and hope in her anyways?"

"Because I saw her and the other detectives at that agency and they all do very well at their jobs. She's is also among one of the agency's sharpest detectives, so if anyone where to solve who the traitor is, it's her."

"Precisely. I agree with you, Tsukauchi. That is the reason why I had hired her in the first place." Principal Nezu said while looking at him.

"She sounds so young! How old is she?" Midnight asks.

"Of course, you would ask that." Mt. Lady muttered.

Midnight glared at her, seething. Everyone else, besides Mt. Lady, deadpanned.

"Ladies, calm down. To answer your question Midnight, she's currently 17."
