It was another horrific battle of the Survey Corps, they gave their all just to take down the three. You're one of the soldier who took down the armored titan. You watch Reiner's body with huge hatred. Clicking your tongue you fixed your gear, getting ready to leave.

"Stay where you are." Hanji said knowing that you're going after Levi.

"No." You said and began to walk.

"Levi, is fine." Hanji said making you sure he's alright.

"How would you know?" You asked glaring at Hanji.

"We need to get away from Reiner!" Armin suddenly shouts, getting your full attention. You and Hanji looked at him, confused to why he looked scared.

"Why?" Hanji Asked. Armin pointed out at the sky, it was a barrel landing near us.

"The colossal titan is going to come down on us from above!! The entire area is going to get blown away!" Armin shouts. Hanji grits her teeth and grabbed your wrist running away from Reiner. Bertholdt left the barrel and went beside his best friend. He looked at you and went towards your direction. Hanji commands to stick to the plan -protect Eren-, but Armin went up to Bertholdt to negotiate.

"BERTHOLDT! LETS TALK!" Armin shouts.

"IF WE TALK... WOULD YOU AGREE TO DIE?!" Bertholdt shouts making Armins eyes widened so as the others. You look away and prepared your gear.

'Something terrible might happen soon.' You thought.

Hanji left to finish off the armored titan, you stayed with Eren to protect him. Mikasa tried to attack Bertholdt from behind but he managed blocked it with his blades and ran away with his gear. As Bertholdt was in mid air he suddenly transforms. You closed your eyes due to its brightness and a gush of steam started to blow you away, separating you from your squad. You used your arms to protect you from flying objects. Your body along with your head suddenly hits something hard like cement making you unconscious. When the steam went off, Jean asks if everyone was alright or alive. Looking around, they noticed you were no where to be seen making them panic.

The colossal titan destroyed houses and created a fire. Throwing burning houses around to create a sea of fire to destroy the place and the people as well.

~

You woke up feeling heat all over your body. Your eyes widened as you noticed the place was on fire. You quickly stood up and look for an exit. Checking your gear if it was still good to go, luckily it was still in good condition. You stared at the other side of the wall, thinking what was happening in there and more importantly how is Levi doing. You aim your anchor from steady buildings to avoid getting an injury. As you were aiming your anchor from building to building and accidentally aimed it to a burning house.

That wrong move ended up giving you an injury, you broke your right arm. Wincing in pain, you tried getting up but failed as you felt something prickly on your leg. You sigh and thought of another plan. You're a bit far from the wall, but you can walk all the way there. Maybe the other soldiers there might aid you. It'll not be your day if you arrived when they're all dead.

Biting your lips knowing it'll be a 50/50 to meet the soldiers alive and another 50/50 to make it up there alive. "Fuck it, i'm going." You said and began to walk slowly and avoided the burning houses, also you tried avoiding the colossal titan to find you.

'I wonder how the others are doing...' You thought.

Meanwhile you're away...

"Yeah, I think they're fine." You said looking at the colossal titan that is covered with steam. You looked at the wall and pouted.

~

As you finally reached your destination, alive, noticing that nobody was there and some corpses was laying there. You face palmed and searched for Levi. You feared if he was finally at the otherside. Shutting your eyes close, praying to the God's above that this is all a bad nad dream. Opening them and nothing has changed.

"Geez fine, I'm going up there." You said, annoyed. Rolling your eyes and fixed your hair. You used your gear to go up the wall, bearing your broken arm. Finally, standing up at the top. You look down and see more corpses and Levi was fighting with the Beast Titan. You grited your teeth and went up to Levi. You used one of the horses to get to Levi. Good thing they were still alive.

Finally reaching Levi, you were surprised that he was talking to the shifter, and the fact he shoved his blade into the shifter's mouth and it went out of his eyes disgust you. Levi heard your foot steps and looked at you.

"[F/n] stay away from here!" Levi said.

"No, I'm going to help you." You said while walking towards him. You stood beside him and stared at the shifter. Your eyes widened at his familiar features and hair specially and he looked like your dad.

"Did you just say her name is [F/n]?" The man said even if it wasn't audible it was a bit understandable.

"Don't kill him yet." You said.

"Not even planning to." Levi said.

"What?" You looked at him weirdly.

"Not yet." Levi said. You two stared at each other for awhile but the man asked.

"What's your last name kid?" He asked.

"Don't have one." You asnwered still staring at him. As you finally realize who he was your mouth suddenly opened. You took the family picture that your dad gave you before he left you.

"No fucking way... You're Zeke?!" You shout.

"Who?" Levi asked not removing his blades off Zeke.

"Zeke, pretty much my asshole brother!" You shouted slightly kicking your long lost brothers body. Levi clicked his tongue and turn his attention back at your brother.

"Now are you going to answer my question or not?" Levi asked.

"I'm going to save you [F/n]." Zeke said and after that a titan took him away. Levi sighed and clicked his tongue in annoyance. He looked at you slightly angry then he looks at the field.

"You and I will talk later. Got that brat?" Levi said.

"Yes sir." You said with a salute.

"Tch, don't sir sir me. You've got explaining to do." Levi said and left the field to check how Eren and the others are doing.

~

When the battle has finally ended, completely ended. Everyone was finally aided, and Armin was also aided. Eren told Armin what happened to him. Armin couldn't believe that he turned into a titan. Your broken arm was finally taken care of by Levi. You thought he'd forget about the Zeke thing, but that's all he could think about. When Levi was done listening to the teenagers he finally turn his attention back to you.

"[F/n]." Levi said sternly.

"Yes babe?" You said acting all innocent.

"Explain, NOW." He said clearly. It took everyones attention and everyone went silent. You stared at them for awhile and sigh in defeat. You took out the picture that you kept for a very long time. It was a family picture that your dad gave.

"My dad gave that before leaving me in Trost. After that I never heard of him. I grew up in the streets for awhile and someone took me in." You said and gave him the photograph. Levi took it and examines it.

"I was 3 when he left me... We originally lived somewhere, I can't recall. Then he met this guy then my dad became a titan and he just took me and suddenly we where in Trost. He was apologizing at me and he gave me that." You said. "I thought he'd be back, but he didn't."

"My mom, we'll I don't really know. I was with my brother, but my dad suddenly took me and ran away from our home town. I didn't understand what was happening since I was still little. He left me unanswered because I wouldn't understand what he was going though. Heck he didn't even told me my last name." You finished. As Levi was examining the picture, he looked at your dad then at Eren.

"Are you a shifter too?" Levi asked.

"No, I'm normal." You said.

Eren on the other hand was massaging his head since he was feeling a severe headache. Mikasa and Armin became worried, but suddenly he saw a part of his dads memory. He gasps loudly and his eyes widened while he breathes heavily.

"[F/n] is... [F-F/n] is my half sister!?" Eren shouts making everyone gasp except for Levi since he was getting there.

"No way... I'M A JAEGER?!" You shout.

"Haha! that was like Levi when he found out his last name was Acker--" Levi slapped Hanji's head before she could finish her sentence.

End.

Extended Ending.

Levi kicked the door to Eren's basement and while looking through some of Eren's dad things he saw a picture in his drawer.

It was the exact picture you had.

"Tch, yeah Jaeger wasn't wrong about [F/n] being his half sister." Levi said and gave the picture to Eren. Eren held the picture and suddenly hugs you tightly.

"Oi Jaeger! Get your hands off her!" Levi said.

"Don't care she's my sister!" Eren said.

"Okay..." You awkwardly say and pat Eren's back.

"Eren..." Mikasa muttered but no one heard her. Eren releases you and suddenly realized something.

"Wait... So that beast dude is my brother too?" Eren asked you.

"Probably." You said with a shrug and with that Eren fainted.

"E-Eren!" Mikasa shouts and picked Eren up.

"Tch, now get back to investigating." Levi said.

Extended Ending End.
