{INFILTRATION} Atsumu Miya x Fem!Reader

𝙵𝚘𝚛𝚝𝚢

You take a deep breath as you look over at Atsumu in the driver's seat of the car. He'd just given you a ride to a street a little ways from Shiratorizawa's headquarters. After a bit of convincing from the two of you onto Osamu and Suna (and a bit of bribery), they agreed to take care of some things on the Inarizaki side of things while you worry about dealing with Semi and Tendou.

"You can do this," Atsumu cheers you on as he plants a kiss on your cheek.

"Thanks," you sigh as you attempt to psych yourself up. "I'll be right back."

Atsumu sends you a cheesy thumbs up and a smile as you step out of the car and close the door behind you with such an intense look it sends chills down his spine. You then start your walk to the building. Just as you round a corner to the front entrance, there's a flash of short, green hair and you bump directly into someone.

"Y/N?!" a familiar voice gasps as their body pulls away from your own.

"Nori?!" you beam as you throw your arms around her, pulling her back into you once more. "Holy crap, I missed you so much!"

Nori smiles as she wraps her arms around your back. "I've been so worried about you, how have you been?"

"I'm good," you answer as you lean away from the embrace. "How are-"

Your sentence is quickly cut off as Nori's eyes widen and she grabs you by the arm, tugging you back around the corner from where you'd just come from.

"What the hell are you doing here?!" she whisper shouts as she looks around as if to make sure nobody can see the two of you. "You shouldn't have come back, Y/N!"

"I need to talk to Semi and Tendou to explain everything to them. And you, too, Nori," you admit.

"Okay, I'll help you get in. Just know that they're both really pissed about the whole Ushijima dying because of Inarizaki thing!"

"It gets worse, too," you sigh.

Nori takes you by the hand and looks you seriously in the eye. "I don't think it could get much worse than this, come on."

You allow her to lead you back around the corner towards the front door of Shiraotirzawa. She sneaks you through the building up to the outside of Semi's office where she knocks on the door.

"Who's there?!" Semi's voice booms seriously from the inside.

"Nori," she replies just as loud.

You could swear you hear a groan just before the door begins to open. On the other side of the threshold stands Tendou who stares down at you with a burn of passionate hatred.

"Back off, loser," Nori groans as she pushes you inside. Tendou stares Nori down as she walks past. Perhaps it's her that he was glaring at? "Semi," she directs towards the new boss of Shiratorizawa, now completely ignoring Tendou's existence, "Y/N says she needs to talk to you."

Semi looks up slowly from his desk. Nori was right, he sure does look pissed. This time you can tell for sure that he's staring daggers into your soul, not Nori's, and a wave of chills flow down your back.

"What the hell are you doing back here again?! Go run back to your little boyfriend in Inarizaki," he shouts with disdain.

"We could really kill you just for being in here," Tendou sings from behind you.

You raise your arms, allow him to pat you down to convince them that you mean no ill will.

"I just want to talk and explain what happened, that's all," you say to Semi. The new boss leans back in his chair, which you take as a signal to begin.

You start by explaining how you met Atsumu, then about your time at Inarizaki and everything that happened between you and Ushijima when you came back, not that you really wanted to admit that to them, but because it's important to your story. When you pick up again, you explain what happened with Nori, who vouches for your story since she's there in person. You end with the points of how Atsumu was shot twice in total and how it was you, not him, who shot and killed Ushijima on the roof.

Once you're done talking and he's heard quite enough, Semi nods and stands up. He silently walks towards you. You begin to plan out your escape, hoping that the door's not locked so you could make a quick break for it if Semi starts to beat the living shit out of you.

"Despite everything that happened..." you continue in a weaker voice than you were talking in before, "I think I have a solution that could solve everything."

Semi doesn't respond, only gracing you with the sound of his shoes impacting with the ground as he approaches you. Once he stops- and is practically hovering over you- he lifts up his arm and presses his gun against the skin of your forehead.

You keep your eyes locked on Semi's, not backing down until disbelief of what happens next causes your eyes to widen. Tendou lifts up his own gun to the side of Semi's head.

"What do you think you're doing?" Semi groans.

"I think we should hear Y/N out," he replies honestly.

Semi scoffs at the response. "About what, you idiot, she killed the boss! There's nothing we can hear her out about unless she can raise him from the fucking dead!"

"I know I can't," you interrupt, "but we need to put everything aside if we want to move on, Semi."

The new Shiratorizawa boss groans as he lowers his gun. "You should have at least come to the funeral," he lectures.

"And if she did that," Tendou chimes in as he pulls his gun away from his friend's head, "you probably would have shot her on sight!"

Semi sighs and nods, agreeing with Tendou. "Alright, Y/N, what is this plan you have?"

You begin to explain to Semi that if Shiratorizawa and Inarizaki come to an agreement and form an alliance, it would create a new, symbiotic relationship. Shiratorizawa will get to keep Sauksa who, in return, can keep his ties with Inarizaki. Additionally, Inarizaki's land previously stolen by Ushijima can be returned without any major, damaging losses to Shiratorizawa.

"You really think you can convince that stuck-up asshole over at Inarizaki to agree to this?" Semi asks intently.

"I'm sure of it," you nod confidently, knowing that Osamu and Suna are beginning to turn the wheels on that train as we speak.

Semi shakes his head, already half-regretting the decision he's about to make. "Fine," he hums, "bring them here one week from now once everybody's settled down and doesn't have the immediate urge to move them all down the second they step foot in here. As for you, Y/N, the identity of the person responsible for killing the former boss remains with only us for now, at least. Do you understand?"

"I do," you nod.

"Nice going, Semi. That was quite the way to phrase all that!" Tendou laughs.

Semi rolls his eyes at Tendou's comment and takes a moment to size you up. "You can go now," he then dismisses you, having enough of seeing your face for the day.

"Thank you, Semi," you bow before nodding to the others and taking your leave. "I promise you won't regret this!"
