Eren's POV

"Shit," I said as I reached out of the Titan's mouth. Armin, my best friend, was reaching out for me. I couldn't die here. I hadn't seen the outside world yet. I haven't killed all the Titans. I haven't said goodbye to all my friends. To her. The Titan's mouth closed shut, my arm falling from it. He swallowed. I fell through his esophagus and landed in his stomach. I looked around and screamed. Dead bodies surrounded me, some without limbs, all bloodied. "No, I can't die!" I shouted with tears in my eyes. There was so much I hadn't done, so much I hadn't seen. But more importantly, I made a promise. A promise I broke.

"Nobody gives a fuck what you want! Stop trying to impose your will on people," I shouted as I headbutted my foster sister Mikasa. She cringed from pain but I was too angry to care. Once again, she was trying to act as if I was some defenseless child. But no longer. Mikasa hung her head.

"I'm sorry, I wasn't thinking clearly," she apologized. I was about to turn my back on her when she tugged at my elbow. I face her. "Please promise me something," she said weakly. "Please don't die." My anger died down a bit, but it was still present. I took my arm away from her grasp and marched off.

"I won't die," I said to her.

I was wrong I suppose. I guess I'm not in control of my fate. Once again, the last moments I spend with someone close to me are wasted with a fight. My mother and now Mikasa. I'd taken her for granted and now, I'd never be able to see her again. More tears started welling up in my eyes. The world is cruel. Nothing but suffering comes from it. I had given up all hope. I just had one final wish before I died. To see my family again. To see her again. I began to sink in the Titan's stomach acids. I raised my severed arm. "It can't end like this! I won't let them. Too many things haven't been said, because of you bastards!" I shouted. "I'll never see my mother again, I'll never leave the walls and explore the outside world with Armin! I'll never be able to tell Mikasa that I-," I was mouth to toes in the Titan's stomach acid. I swore once more in my mind. The Titans would die by my hands for what they've taken from me. Everything went dark after that. All I could see was myself, standing over the body of the Titan that had previously devoured me. Another Titan, a smaller one appeared and leaped towards me. I killed it instantly with one punch. All I could think about was killing more. More. I had to kill more. I would kill them all.

Mikasa's POV

I lay on my bed with tears in my eyes. He promised me he wouldn't die. The feeling I had was all too familiar with me. I had gone through it twice before. My family was gone again. Why? Why did this keep happening to me? I did nothing wrong. Maybe it was all for some God's amusement. I felt like I couldn't go on. My life had no purpose anymore. This is a cruel world we live in, but also a very beautiful one. I felt the scarf around my neck for comfort. The one that Eren had given me a few years ago. I was jolted out of my thoughts by a knock on my door. One of the commanders came in. "Ackerman, we need your assistance in dealing with the Titans that have infiltrated the wall. We know you're in mourning but this cannot delay," he said as he exited my room. I sighed. Maybe that would be the day I died. I really didn't care.

Everybody, including Armin looked at me with pity and concern. It had been Armin who had delivered the news of Eren's death to me the previous day. Armin quickly relayed his plan to kill all the Titans in the area but I dismissed it just as quickly. "Why?" he asked.

"I will take care of the Titans. I am strong. Stronger than all of you. I'm more than capable of taking care of them myself," I said as I grappled to a nearby building. The others were close to follow me. I zipped from one Titan to another, slicing the napes of their necks as I went along. This was meaningless. They were impossible to beat. They would just end up eating us all. Suddenly, while mid-air, the gas in my 3-D Maneuver Gear ran out and I fell to the ground. "I should have paid more attention to my gas," I said to myself before dropping my swords. I wasn't thinking straight. Eren's death clouded my judgement and outlook on life. I knelt down on the floor as closed my eyes. I led a good life, no matter how much tragedy was mixed up in it. A Titan turned into the corner and faced me. Another one came from behind me, this one more muscular and lean than the first which had a fat belly. Eren's voice crept into my head, telling me to fight. Then I realized that if I was to die there, all my memories would be lost, including those of Eren. I had to fight. No matter what! I grabbed my swords and readied myself for an attack when the unimaginable occurred. The muscular Titan attack the other one. With one right hook, the first Titan was down, leaving the muscular one victorious. He stood over the body of his opponent and exhaled. I couldn't believe my eyes. In a blind fury, the Rogue Titan repeatedly stomped on the fallen one's neck. He screeched in anger and then a memory came back in my mind. Of when Eren saved me from me parent's murderers.

"Don't get up! Stay down! This is what you deserve you animal!" he shouted as he continuously stabbed the murderer in the chest. The Rogue Titan was angry, that much was clear. But there was something more than that present. When that Titan killed the other, I felt like I could see Mankind's rage in physical form. The same rage that Eren had used to save me. The same that had spurred him into joining the military. The same that ultimately got him killed. I couldn't help but feel at awe. To feel inspired. That Titan helped me carry on. It made me want to carry out Eren's dream.

So that's Chapter 1 finished. Just an alternate take on Eren's transformation into a Titan. This will cover the Female Titan Arc as well as the Breach Arc so this will be going on for some time. Please review and check out my profile for my other AU Shingeki no Kyojin fanfic.

I don't own Shingeki no Kyojin hence the reason why I am writing about it on a fanfiction site and not in the manga.
