(By the way this is my first AOT fan fic, so if you could leave your reviews that'd be great and maybe I'll ask a question throughout the chapters and will write a story for the first winner that messages me the answer correctly)

(Also I do not own Attack on Titan or any of these characters)

"Yes! I have done it!" yells Hanji at the top her lungs happily, it spreads through the whole castle from her office. "The Gender Bender is complete!" she begins jumping around all bubbly, she's loving this.

"What the HELL is going on I here?! Jesus! I can hear you through the whole fucking castle!" yells Levi with his usual scowl. "I have completed my machine!" yells Hanji running up to Levi, he can see the sweat beading down off of her face. "Disgusting, Okay whatever. What are you going to do now?" Levi speaks slowly as he backs away from her; he continues to scowl as he crosses his arms.

"I will need a willing test subject, perhaps maybe…" Hanji begins but Levi cuts her off "No" He says simply "Don't even think about going there, I'm warning you." He says turning his head towards the window. He steps back and leans up against the wall with his usual leg up foot against the wall position.

"Fine… what about Eren then?" Hanji asks thoughtfully, she leans slightly to the left and puts her hands on her hips. "I highly doubt that he'll agree willingly but, that's your choice so, be my guest" Levi says stepping aside with his arm extended facing the door for Hanji. Hanji books out of the door into the hallway screaming Eren's name almost at the top of her lungs, Levi chuckles and begins to follow at a slower pace.

"EREN!" She screams entering the dining hall smashing into Eren's side huffing and puffing trying to catch her breath, Levi leans in the door way with a sly smirk on his face. "Hey!" Eren yells startled and in pain "What the hell was that for?!" He says as Hanji leans on his shoulder trying to catch breath. "I need you to test something" She begins slowly, "Hum okay… what?" Eren asks slightly concerned, considering its one of Hanji's experiments. "My new machine! The Gender Bender! "She says now smiling with a menacing grin that Eren had never liked. "Well… What d-does it d-do e-e-exactly?" Eren say's very scared now. "I'll explain it to you later" Hanji says yanking Eren along out into the hallway.

They begin walking down the hallway to Hanji's office, Levi close on their heels.

"Good job by the way Levi, for volunteering to be present for the experiment" Hanji says happily walking into her office. "Yeah it's my job, don't forget that." Says Levi frowning, and he rolls his eyes as he follows her and Eren. "Okay are we already then" Hanji asks quickly, "Uh I dunno" Eren says slightly then all of a sudden Hanji shoves Eren inside of the machine.

Hanji flashes Eren the same menacing grin that she gets when she's really over whelmed. "Now now Eren, no need to be fussy" she says laughing as Eren shows signs of anger. Eren begins banging on the glass, he's really frustrated now. He begins to yell as well but he realizes that they cannot hear him. Then he realizes something else, its sound proof glass.

Hanji glares over from Levi to Eren and sees Eren yelling, "Eren, what did I say?" Hanji says frowning, Eren sits there scared and confused and angry all at the same time, his head begins to swirl and he gets a headache.

"Are you sure that this is safe?" Levi asks with some bit of concern in his voice, it slowly disappears when he spares a glance over towards Eren. "Oh of course he is!" Hanji says smiling once again "Okay I think we're ready then" Hanji moves over towards the dials and checks to make sure everything is intact.

She reaches for the lever and slowly places her hand onto it, sweat pouring from her forehead.

(Thanks for reading I hope you enjoyed it, stay tuned for chapter 2 The Switch)
