The tension between the two imposters was thick as they walked towards the cafeteria, neither of them saying a word. Oikawa stopped in front of the door and pressed a few buttons on his tablet, making it slide open. He moved out of the way and smirked at Sugawara.
"After you," he sneered, and Suga frowned as he walked past him.

Toru closed the door behind them and turned around to see the abdomen part of Sugawara's suit opening up to reveal the frothing mouth and razor-sharp teeth where his stomach should be.
"I can't wait to eat you whole," it growled.
"You know, I always thought that that was absolutely disgusting," Oikawa sighed as the back of his suit tore open to reveal dozens of black tentacles.
"Like that's any better," Sugawara retorted, taking out his gun and pointing it at Oikawa. "Let's make this quick alright, Y/n is in the room by herself, and I'd hate to keep her waiting."

You held Yachi and Bokuto closer to you as you rushed to the ejection room. Loud shouts followed by crashes and bangs came from the cafeteria, and you had deemed it better to go through storage and communication. Even though it was a long way, it was the safest, and it prevented you from coming in contact with either imposters.

You stopped in front of the doors to the storage room and set the two mini crewmates down before taking out your tablet and pressing the open button for the door, only for your brow to furrow in confusion when nothing happened. You pressed the button repeatedly, panic slowly rising in your chest with each failed attempt. Yachi and Bokuto looked up at you worriedly as you let out a frustrated sigh.

"I-I don't know what happened," you muttered, running your fingers through your hair in frustration. "Maybe connecting the tablet to both the TVs and the radio somehow interfered with its original programming to just be able to open and close doors and complete tasks." Bokuto looked back and forth in between you and the doors.
"I...I'd have to disconnect both the TV's and the radio, but that...that would take too long, and the only other way to get through is by going through the cafeteria."

You and both mini crewmates jumped, hearing a particularly loud slam that made the entire ship shake and the lights flicker, and that's when an idea suddenly came to mind.

"We might be able to get past them after all," you muttered to yourself before kneeling in front of both mini crewmates.
"I have an idea. It's risky, and there's no time to explain it now, but you two will have to trust me. Do you trust me?" The two looked at each other before turning back to you and nodding, and you smiled as you grabbed Yachi and placed her on top of your helmet, and scooped Bokuto up into your arms before running back to the cafeteria.

"If we're lucky, they'll be too busy fighting each other to notice us, and we'll be able to sneak past them," you informed the two as you turned the corner. The door to the cafeteria was closed as well, but before you could even wonder about how you'd get it open, a loud crash made you slap your hand over your mouth to keep from screaming. You watched the door come crashing down to reveal Oikawa and Sugawara fighting in the middle of the cafeteria.

A bunch of Oikawa's tentacles had been torn off and were now scattered across the floor, small pools of black blood leaking onto the floor around them. Sugawara was in no better shape, in the middle of the ground laid, the tip of the tongue from the mouth on his abdomen, and you could see a few of its teeth on the ground. The two imposters stood covered in blood and bruises, but neither of them looked like they were ready to give up. You had to cover your mouth to keep from throwing up before looking at Yachi and Bokuto.
"Both of you close your eyes, alright?" The two nodded, and you took a calming breath.

'I can do this.'

You crouched down and slowly entered the room, quickly rushing to hide behind the table that sat propped against the wall. Luckily, Oikawa and Sugawara were on the other side of the room, and you looked ahead. There was another table that you could hide behind just a few paces ahead, but just as you moved to rush over to it, you gasped as the table you were hiding behind shook violently. Oikawa had thrown Sugawara into it. You gripped your hand to stop it from shaking as you listened closely. Eventually, Suga got up and lunged at Oikawa, and you took the chance to dash over to the second table.

You repeated the process for a moment until there were no more tables left to hide behind, and you bit your lip nervously, seeing the distance between where you were and the door. You peaked your head out from behind the table to see that Sugawara had pinned the brunette down and was punching him repeatedly. While he was distracted, you stood up and rushed towards the door, making sure to close it behind you. You smiled at Yachi and Bokuto.

"We made it."

***

You ran to the ejection room and opened the door to see a small ship had attached to the other opening. A male with dark hair and brown eyes stood in the entryway and let out a sigh of relief when he saw you.
"Ready to go?" He asked, and you smiled, recognizing the voice.
"Daichi!" You said, rushing over and wrapping your around around his neck, hugging him tightly.
"Come on, let's get you out of here," he said once you let him go, and you followed him into the ship. He sat down in the captains' seat, making sure to close the doors behind you two before grabbing the radio.
"This is Daichi Sawamura to headquarters," he said. "I've retrieved the survivor, and I'm heading back-"

A loud gunshot rang throughout the ship, followed by a thud as the male fell to the ground. You stood there with a smirk on your face as you kicked his body out of the way. You looked over the control panel for a moment before pressing the button, making the doors reopen. You turned to smirk at Yachi and Bokuto, who stood there, seemingly in shock, but at the sight of you walking over to them, they began trembling in fear.
"Don't look so scared," you said, petting them on the head. "You trust me, right?"

You opened the door to the cafeteria to see Oikawa and Sugawara standing on the opposite sides of the room. Sugawara sat on his knees, and Oikawa had bent down with his hands resting on his knees, but at the sound of the door opening, their heads snapped towards you.

"Angel, what are you doing here?" Sugawara asked.
"Go back to your room, princess. Everything will be okay," said Toru, and you chuckled.
"You're right, Toru," you said, taking out your gun. "Everything will be just fine." You pointed it at Sugawara, shooting him directly in the leg, successfully crippling him, but before either of them could say anything, you did the same thing to Oikawa.
"Angel," Suga let out a pained groan. "Why?!"

"Because although you two completed your mission in killing all of the humans on this ship, you have both developed human emotions in the process for someone you thought was a human, but that's still breaking the rules, so you two have to be terminated."
"What...do you mean?" Oikawa grunted, and a sinister grin spread across your face, but both male's eyes widened as they watched your mouth spread unnaturally, revealing the razor-sharp teeth. You licked your lips as your tongue grew longer, and the tip became as sharp as a needle.

"Why would they send just two imposters when three could better guarantee success?" You laughed as the back of your suit tore, revealing tentacles similar to Oikawa's. "Well, I wasn't actually sent here to kill anyone, but rather to make sure you two did your jobs right." You used two of them to wrap around their necks and lift them, and you smiled, seeing that they had rendered themselves too weak to fight back.

I'm going to split this next bit into two different options. Option A will be for those who like Sugawara more and option B will be for those who favored Oikawa and it'll just continue into the rest of the story.

[Option A]

"Any last words?" You asked, turning to face Oikawa only to frown, seeing that he had already died of blood loss.
"Shame," you sighed before turning to Sugawara, but your brow furrowed in confusion when you saw the soft smile on his face.
"Something funny?" You asked.
"It's just..." He coughed. "Even now, like this...you're so beautiful. Even now, I still can't stop loving you... and deep down, I think you did love me too, maybe even both of us." You lowered your head to hide the tears the began to roll down your face.
"I did," you admitted. "And that's why you have to die." You tightened your grip around his throat.
"Please," he whispered. "Please don't ever forget how much I love-"A sickening crack cut off his sentence as you felt his body go limp in your hold.

[Option B]

You tightened your grip around Sugawara's neck until he eventually stopped struggling, and his coughs and gasps went silent.
"Now for you," you said to Oikawa, but you didn't move.
"Something wrong, princess-"
"Shut up!" You shouted. "Why did you call me that just now? You should hate me for betraying you!" You looked up to glare at him again, but he just stared at you, eyes full of love and adoration.
"I could never hate my princess," he whispered, and at that, you let out a sob.
"Don't cry, princess," Oikawa coughed. "This is how it had to be, and although I wish it could've been different, I'm still happy...that I got to meet you. I love you so much." You hiccuped quietly.
"I love you too," you whispered, as the male's body went limp in your hold.

You dropped both of their corpses to the ground, not sparing either of them a second glance as you turned and headed back to the ship, silent tears streaming down your face as you closed the door and turned on the radio, and tapped into another station.

"This is Y/n L/n with the final mission report," you said. "Mission complete. All humans on the ship have been terminated, but unfortunately, we lost Sugawara and Oikawa in the process. I will be returning now. Over."

A/n:

I cried writing Oikawa's part.
