Unfortunately, no one told me the slut rule applied to boys. Eren walked into Nifa's house, overwhelmed by the people and overall lack of clothing. Bertholdt and Reiner were dressed in matching half-togas (how can you "half" a toga? Isn't that technically half already?) and were either really drunk or really shameless. Jean-you guessed it- was galloping around the room in a horse head and underwear while chasing Marco, who wasn't really running because of the broken leg. Even when uncovered Annie managed to cover herself up. Hannah and Franz sloppily made out, which...wasn't that different from a normal day. Erwin (still in a firefighter hat) noticed Eren due to his appalling vampire costume, which was really decked out with fake blood and "I'll Kill Them All" written on a pin Eren wore. "Hi! You made-why are you dressed so scary?"

"Why aren't you?" Eren questioned with a nervous chuckle. "It's Halloween." Erwin rolled his eyes and giggled, making a bunch of girls swoon and fall over. Hanji carefully stepped over the pile of girls, a frantic look in her eyes. "Have you seen Mike?" They both shook their heads, causing the witch to trample over the pile as she made her way into the kitchen with a huff. Auruo met up with Erwin while Petra was trying to sell her "nice girl" act. Why else would a Recon dress like an angel? Noticing Auruo was here, Erwin turned excitedly to the devil. "You know who's looking fine tonight? Armin Arlert." Eren spit out any water he was coincidentally holding in. Auruo seemed to think the same, but held it in better than the angsty teen. "Okay, you did not just say that." "What? He's a good kisser." "For god's sake, he's your cousin!" "But you have your first cousins, and then you have your second cousins, and-" Auruo seemed visibly disgusted at this point. "No, Erwin. That's not right. Not at all." In response, the eyebrow-heavy boy shrugged and chased after the helpless nerd.

Just then, Levi emerged from the bathroom. "Shitty Hanji, letting in her damn dung beetle in her damn car without telling me. How was I supposed to know what his damn dung looks lik-". The tiny teen noticed Eren and realized it was time to take action. "Oi, Eren, You made it...and you're a...humanized bat." Eren smiled through his teeth. "Vampire, actually." "Looks fab. Lemme get you some punch."
Mikasa was at the center of the party, along with a bunch of military girls, who were dressed in army bikinis. "Oi, Mikasa." She didn't need to feel the tug of her stockings to know who was addressing her. "What is it, Levi?" She soon noticed her past brother's outfit and groaned. "Oh, jeez. Didn't anyone tell you this was a costume party?" Levi ignored her. "Whatever. I need to talk to you." Mikasa snickered. This should be good.

"You know that new kid, Jaeger?" "Yeah, he's cool. I invited him." Levi smiled secretly and an evil gleam shone in his eyes. "Well, you should really be careful because he has a huge crush on you." The scarf-clad girl (who wasn't wearing a scarf today, surprisingly) stopped whatever she was doing. "What? Really? How do you know?" "He told me, duh. He tells everybody. It's kind of kawaii. I heard he writes 'Eren Ackerman's Future Baby Names' all over his notebook. Oh, and he made this pin "I'll Kill Them All For You, Mikasa!" and he wears it under all his clothes." Even though she was used to Levi's bullshit before, she couldn't help wondering if this was true. "You're kidding, right?" "Well, who can blame him? You're badass glam. And okay, look. I'm not saying he's messed up, but he took a thread from your scarf and sent it to Maria so he could brag to the hobos there that he finally got a piece of you." Her eyes bulged out of their sockets. "WHAT?"

Meanwhile, Eren turned to the opposite direction of Erwin pinning Armin to a wall and noticed the shorty and his old sister. Oh my god, this is it! Levi said he would talk to Mikasa for me and he is! I loooooove the Recons!
"...I know he's kind of mentally insane and creepy, but just promise me you won't make fun of him. I've already made enough enemies." Though it was a hard decision, Mikasa swallowed her rage. "Of course I won't." Levi faked innocence yet again. "Do you want to join the sibling pact again? You know, so Eren won't bother you?" She rolled her eyes. "Levi, I can defend myself." The tiny teen thought fast. "B-but wouldn't you want to know if he would? You know, to prepare for what's going to happen. He's nearly a Recon, you know." This was bullshit, and Mikasa knew it. Still, she missed her old brother and wouldn't mind joining forces with him again. "Alright. I'm in." "Oi, that's great!" He turned on his kawaii face. "Sibling hug?" She rolled her eyes and snickered. "Okay, you big baby."
Over her shoulder, Levi smirked and stared back at the unsuspecting Jaegerbomb. The fun was just getting started.

Everything was going great for Eren. He put all his faith in Levi from the start, and didn't seem like any of it was faltering. Sasha and Connie are crazy. How could they hate Levi? He's so...such a...He nearly dropped his punch cup.
Levi.
Mikasa.
Hugging. Levi made the nastiest smirk known to man and aimed it at Eren.
Such a liar! Eren let out an anguished cry of angst, which he hoped was low.

"You're the best, lil' Ackerman. Hey, do you hear that dying cat noise?" Levi smiled internally. Even though she used that name for him, ruining a kawaii boy's life was more than enough to get it out of his mind. "Cat? Weird. Hanji must have let it in or something. It still ruined the moment." Mikasa giggled and merely pet Levi's tiny head.

"What are you supposed to be? A humanized bat?" Jean let out a whinny at Eren's frazzled state. "S-shut up, seabiscuit!" I had never felt this way before. I could hear my heartbeat pulsing through my internal system. My stomach felt like it was swirling in the nether depths of despair, never to be retrieved again. The lump in my throat didn't seem to be subsiding, a constant memory of my gloom. To put it in non-angsty terms, I was really sad. I hated Levi. I hated him so much.

The outcast duo sat on the worn out couch, Sasha practically eating the popcorn bowl and Connie leaning forward to catch the good parts of the movie. "On that day, humanity received a grim reminder. They lived in fear of the-"
BANG!
The door flew open, revealing a puffy eyed vampire, the "I'll Kill Them All" badge ripped off of its fabric. The screams Connie and Sasha made were enough to wake the dead. At a completely unrelated moment, Mylius clumsily stumbled out of his house, a confused look on his face and a sleeping mask on his eyes.
"Eren, why aren't you at the party?" The glum vampire mumbled, "He took her back. Levi took Mikasa back."

Sasha wore a mask of sympathy while rage sparked in Connie's eyes. "Why would he do that? I thought we were friends." The bald boy spat venomously. "It's because he's a life ruiner. He ruins people's lives." "That's right! When we were in elementary school, Levi convinced the ENTIRE SCHOOL that Connie was-" "Sasha, please! Look, we're not going to let him pry his clean, tiny fingers in our lives. We're taking action. Now, Ackerman is a dictator. How do you overthrow a dictator?"
"By fleeing the land he owns discreetly and starting a new life in Ame-"
"By cutting off his resources!"

-Genderbent bodyguard with height (Mikasa)

-Incognito fetish pleaser tools(Windex, hand sanitizer, wet wipes- you name it!)

-Cape cult worshippers (The Recons)

Connie was still rambling about the plan and making sure to see that Eren was listening. "So, if you want this plan to work, you need to pretend like nothing is wrong and keep hanging out with them. Can you do that?" Can I do that? Does it involve acting? I remember I won an award last year for being the greatest actor in Maria High because of my monologue, "The Colossal Onslaught". Does that count? I'll pretend it does. "Of course I can." The bald boy grinned a wolfish grin and Sasha followed suit. "Alrighty, then. Let's rock this bitch."

AN: The sibling pact is basically this...pact where two people decide to be family. They get access to do sibling-ish things with each other. Or not, that's fine, too. People not in a sibling pact can still act like siblings though. *cough cough* canon eremin *cough cough*
It's basically "legal" documentation of a family. Just please bear with me okay thank you. Until next time! woohooooooo~
