Summary: Eren wasn't the only kid in the Yaeger family. He had an older sister that disappeared when Eren was 10. Now, she is back. His sister joins the scout regiment with him, both the same dream, still the same people, same friends still there, but some things have changed. When she falls for the cruel, stony-faced captain, what will she do? What about their powers and the fact that the fraternal twins are both titans?


Unknown POV.

I walked through the woods as my black outfit blended me in. I had to leave before it was too late. Before my powers went haywire and I wouldn't be able to control them again. It already flared when those guys attacked Armin. Luckily Mikasa was there to finish them off and hold me back. She didn't know though. No one knew and that was my reason to leave.

Dad said it was for our own good, but what good is it when I might kill someone if they tick me off? What'll happen then? What the hell was in that fluid anyway? I thought as I wiped the tears off my face. No more crying. No more tears. From this day forward, I will never cry as long as I live. I will hold this promise to my life.

The shadows engulfed me as I walked on, my backpack and everything I would need inside. Fight. Survive and win. Lose, pay with a part of your life. All or none. Win or lose. Those words ran through the hamster wheel in my head. I had taught Eren my saying, but he never really remembered it, so he stuck with his own version. I breathed out. I hope he'll be OK, but with Mikasa by his side, he'd be invincible. One more tear formed form my bright turquoise eyes, spilling to the ground. It was done. My promise was complete.

Goodbye Eren. Goodbye Mikasa. Goodbye Armin. I'll come back. Don't worry.


*Time lapse (to when the titans get into wall Maria)

I ran. I ran the whole way. To our house, to where Eren and Mikasa should be. My heart beat faster as my unnatural speed came through. My legs carried me to the place I left. The place that I thought I wouldn't have to see the same. But, now I had to. I had to save my family. The people I left behind. Because that might be the only thing I can do to regain their forgiveness.

It was too late though. Right in front of me, my own mother was dug out of the rubble and eaten by a titan. My eyes flashed red as I used the 3DMG I stole and mastered. Taking the blades out, I sliced through the titan's stomach, but the blade didn't pass through all the way. An aura of anger surrounded me as I sliced through the titan's nape of the neck and down it fell. I wanted to cry. I wanted to cry so badly because my Mom was gone. And I couldn't do anything about it. But I knew I couldn't cry. I couldn't because it would never help me. Because I would never get over this.

I scanned the perimeter and saw Eren and Mikasa with a Garrison soldier. I ran up to them. I'll have to admit, the looks on their faces was priceless. I smiled for the first time in three years at the duo.

"Get them to the boat!" I told the blonde guy running with the two people I hadn't seen for so long, but I could explain later. Right now, it was time to run.

"Where have you BEEN?!" Eren screeched. I sighed. He pounded on the Garrison's back. "NO! I need to go back!"

"I'll explain later. Go, go ,go!"

Finally, we reached the docks and got hauled on. People were screaming and demanding that they get on. I held tight to their wrists as we spotted Armin. That wasn't the only thing, because Eren looked weird. Like, a scary, possessed, crazed weird. I was betting that everyone who saw what the titans were capable of drove them downhill. I kept my mask of determination on as Armin came over. Breathing heavily, I greeted him with a hug. I didn't normally hug people, so of course, like everyone else, he was surprised. Then, I turned to Eren and Mikasa and squeezed the life out of them.

"I'm so sorry. I'm so sorry. I'm so fucking sorry I left you." I repeated like I was chanting.

"C-can't BREATHE." The Eren said while Mikasa just hugged me back, a tear rolling down her cheek.

I laughed. letting go of my family. "Okay, now I'll explain. I ran away from home to protect you. I don't exactly remember why, but something was going on. Something big. I don't know what, but it has to do with Dad." Realization hitting me, I looked around.

"Dad, he isn't... is he?" My bright eyes widened.

"No, but we don't know where he is." Mikasa answered, relieving me, but frightening me all at once.

Then, they had to the one thing that could have annoyed me the most if not out current situation. They started arguing. I looked at Armin and he shrugged.

"Hey, where did you get the 3DMG?" Eren asked me. Oh, shit. Time to go into further detail.
