Chapter 1: The Jaeger's New Family Member

Walking down the dingy streets within the Underground District, was a (H/c)-ette girl with unforgetable (E/c) eyes, she was only a 10 year old, but more deadly than any army.

This girl was named (Y/n) (L/n), who was going to visit Grisha Jaeger and Carla Jaeger, who have a 9 year old son, Eren Jaeger. The two became friends a year back, as well as Eren's other friend, Armin Arlert.

(Y/n) expertly used 3D-Gear {Omni-Directional-Maneuver-Gear / 3D-Maneuver-Gear} that she stole, to get out one of the holes at the top of her District. Sneaking away from the hole, on her way out of Wall Sina she saw some MPs around the wall, she equiped her cloak and use the gear to fly to the top of the Wall.

Once she had knocked out the guard she then jumped down into Wall Rose. (Y/n) ran through the crowded streets, jumping and dodging occasionally when the obstacles were in front of her. People chattering away, talking, and minding there own business.

After she climbed Wall Rose, with the help of 3D-Gear, she then went down to Trost District. Making sure not to be seen by any soliders, she stuck to the ally-ways, like before. While walking she heard a, what seemed to be, young male voice yelling at a older woman, or thats what it sounds like.

"SHUT UP, I WAS BUSY YOU OLD HAG!"

"ITS OMELETS, YOUR FAVOURITE!"

"I'M NOT HUNGRY, GO AWAY"

Slam! A door seemed to be slammed, most-likely ending the argument.

A boy with two-tone hair stormed out of the building, growling to himself. As he was walking, he didn't see (Y/n), so he bashed into her. "Hey, be careful." (Y/n) calmly stated, as she pulled down the hood on her cloak.

"Huh?! Hey! wat- Uh oh, sorry miss, I didn't see you, I'm Jean." The newly informed Jean introduced, holding out his hand. (Y/n) shook his hand, introducing herself. "You know, your should be nicer to people, especially if they make you food." She said. Jean looked at her for a minute. "Yeah, I know, I was just busy and I like to be alone sometimes" "I get that, don't worry about Jean, everyone needs there space." (Y/n) smiled slightly, showing kindness in her (e/c) orbs, the unforgetable, mysterious and captivating eyes, that drew people closer to her.

Jean smile back, and nodded. "Jean-Boy! I want you to eat these omelelts! Its a waste of food if you don't!" The woman yelled poking her head out of the door. "Mum, I was talking to.. a friend..?" Jean replied. "Yes, I'm a friend of Jean-Boy here, I'll see you around, I've got to go meet someone." (Y/n) smirked, and walked off.

Jean stared at her a minute. "Has my little Jean-Boy found a friend? Its about time you did, after all you are nine years old." "Okay mum, okay." Jean walked in his house, and sat at the table waiting for his food.

(Y/n) was finally in Shiganshina, walking up to the Jaeger house hold, knocking on the door.

Knock! Knock! Knock!

(Y/n) waited for a moment, and then the door opened to see Carla Jaeger. "Hello Carla, may I visit you and the family today?" "Of course (Y/n)! Welcome" Carla greated as she let (Y/n) in, while (Y/n) muttered a 'thank you' to the woman. Then Grisha walked in. "Ah (Y/n), hello, may we talk?" "Sure." She replied, as Carla went to get groceries. She put her cloak down, and hid her 3D-Gear under the cloak - Incase Eren sees.

"Now, about that Titan serum, the type you have multiplied your DNA, you have pure human blood, but two sets of DNA, one Titan-Shifter and the other Pure Human. So because of this, I suggest you shift, once a week, or you might have serious consequences. Though saying this, the healing power is avalible at any time." Grisha infromed. (Y/n) nodded. "Where's Eren?" She asked "Oh, hes out with Armin, he'll be back soon for the check-up I have later." "With who may I ask?" "The..Ackerman's Household. I'm checking up on a 9 year old girl, named Mikasa. Would you like to come?" "Of course, you taught me about being a medic, so I might as well come along." (Y/n) replied.
