Backstory for my attack on titan fan character.

ackstory: 

Amelia lived with her brother and her father for many years in the underground. Her father had broken legs and couldn't do much to feed his kids. Amelia's brother Aiden, on the other hand, stole food and other necessitates to survive. When Amelia reached age 10, her brother taught her how to steal without getting caught and, if she does get caught, what to do. "So Mel, always hide in the shadows and take food when nobody is looking. If they happen to spot you, drop whatever you have and run. But only if you're carrying a lot. If you're only carrying a small amount, keep it with you," Aiden told her. She nodded in response. 

As Amelia got older and started puberty, she had started to use her gender and body to get what she wants. She started to wear skimpy clothing to distract the shop owners and attempt to persuade them to give her what she wants. Amelia mostly tried to seduce doctors and alchemists, so she could help the only two people she cared about: Aiden and her dad. All of them declined. One unfortunate day, at age 15, her father had been killed. There had been one particular doctor she had harassed due to his medicine being known to be the most effective. She soon found out that the doctor had contracted three thugs to take care of her father, as revenge. This hurt her mentally and she had decided to enact her revenge. A twisted smile had formed on her face. Aiden put his hand on her shoulder. "Don't do anything stupid, Mel," he whispered.  

That night, Amelia sneaked into the doctor's house. She held a knife to his sleeping body. "Wakey, wakey. Someone sure's a heavy sleeper, aren't they mister?" she said in a gentle voice. The doctor slowly opened his eyes. "What... what do you want, crazy?" the doctor murmured sluggishly. Amelia smiled. "A little birdie told me that a certain doctor hired thugs to kill my dad. Three of them. It was also oddly clean. Do you care to tell me who?" she questioned. Her twisted smile grew and Amelia pushed the knife closer to his neck. "A black hair boy, real short. He's a clean freak. Tall one with brownish blonde hair. And a kid. A girl. Red hair, orange clothes," the doctor gulped. Amelia took a step back. "Thank you. Who knows? Maybe you will like what you see one day. You can't deny it forever," Amelia replied curtly and left.

The thugs he hired were the best of the best. They even managed to get their hands on ODM gear. She didn't care, however. Revenge meant the most to her. Her father was innocent, he never did anything wrong. Everyone who specializes in some black market dealing knew where their house was. She marched right their and opened the door. "WHAT THE HELL IS WRONG WITH YOU? HE WAS INNOCENT!" she yelled at the top of he voice. The girl and the tall man was asleep, while the man with black hair was cleaning down a knife. "What?" the tall man croaked. He was clearly quite drowsy. Amelia pointed her finger at the short one. "And you, Mr clean freak! You have the guts to clean up the mess you made while leaving his limp, lifeless body just lying there?" Amelia screamed. The short man just glared at her. "What are you talking about?" the tall man asked. "Farlan, ignore her. She's clearly crazy," the clean freak said.

"Crazy? Me, crazy? I think I have every right to be mad if you killed my father! He was innocent! He never did anything wrong! His legs were bad! I had to do what I had to do! That doctor..." Amelia trailed off. "The doctor?" the girl murmured. "You know fully well who I'm talking about. He hired you to kill my dad. All I needed was that damn medicine and he'd be alright!" Amelia shouted. She was starting to lose her energy. She aimed her knife at the shortest. "You're the most disgusting. Who the hell cleans up after themselves when they murder someone in cold blood?" Amelia was on the verge of crying. She started to walk to the clean freak. When she was close, she lunged at him. The man kicked her knees in and she fell to the ground.

"Listen, kid. You're not the only one who does what they do to the survive. A lot of people do the same. We do so, too. You do well to remember that," he spoke quite bluntly. "Wait for it. Karma's coming for you," she mumbled. Amelia got herself up, brushed her dress down and left. The man grabbed her collar. "You haven't cleaned up," he pointed out. "Let her go, Levi. I think she's been through enough," the tall one said. The black haired man clicked his tongue and let go. Amelia looked back at the trio one last time.

*Amelia's point of view*

'Don't hate the messenger' they always say. I can't believe I let that doctor go. Well, looks like I'm taking care of him before I go home. I arrived at the doctors house once more. "If you don't like what you see now, I guess you never will. And what's the point in living if you can't understand beauty?" I told him. He opened his dreary eyes one more, just to see me stab him in the heart. A smirk grew across my face. 'One of these days, I'll go back for those thugs" I thought. I raided the doctor's house - taking medicine and money. I returned home after.

A few months after the situation, I heard the three thugs got captured by the military. "Aiden, I'm leaving for the surface. I'm sorry. There's something I have to take care of," I declare to my brother. He looked at me with concern. "It's about those thugs, isn't it?" he asked. I nodded my head. "Not a lot I can do when you have your mind set on something, Mel. Just don't get hurt," he continued. I nodded again and took some of the money I saved from the doctor. I paid off the people at the gates and left.

After a year of navigating the surface, stalking members of the military and petty thievery, I found one of them. The other two were missing. His lifeless eyes was what I remembered the most. He killed my dad in cold blood. I really had no interest in truly joining a military, I can't even begin to understand why a thug would join, so I had decided to steal some gear. When the thug and his group left for an expedition, that's when I infiltrated the building. My mission was simple: get in, get their silly uniform and get out. I managed it successfully without getting caught.

When they had returned from their expedition, I waited until nightfall. I sneaked into the military's building once again and searched for the thug's room. It took longer than expected because he was located in an area for higher-ups. His room was oddly clean. I mean, I knew he was a clean freak but this went above and beyond. I was about to stab him, but a thought crossed me. That man told me they needed to do what they had to, just so they could survive like me. I sighed and I made some tea to think this out.

It's not like I'm doing anything out of the ordinary, he deserves some karma for what he did. I sat cross-legged in front of his bed. I kept thinking about what to do. After a long period of time, I put the cup down and got up to leave. "You got away this time," I said under my breath. It wouldn't exactly be fair to kill him, I'd do the same in his position. I turned my back on him. Without warning, something hard struck the back of my head. "You come here, still one of the cadet's clothes and don't even clean up?" a harsh voice said. That freak was awake the entire time.

"I don't know who you are or what you're mumbling on about, but you better have a damn good reason for this." He muttered. I lifted my head back up and turned to face him. I've grown, he's much smaller than last time. "You should be thanking this pretty face. You could have been dead," I retorted. I smiled at him. "I was going to kill you, but it would be such a shame to let such a handsome man go to waste. Don't you agree?" I mocked. He didn't stop glaring at me, however it did look like something clicked in his head. "Listen, you brat. You better get out of here and not come back. You should also get over it, people die all the time." he said bluntly.

Heartless. I knelt down to his height and looked him straight in the eyes. "He was innocent and has bad legs. That silly doctor wouldn't give us medicine," I smirked. I gave him my most seductive look and grabbed his chin. I started pulling him towards me. He slapped me again. I guess I couldn't really expect any less from him. The freak probably wouldn't fall for my attempt to get him to over look this. "Get out," he demanded. The small man still sounded blunt and harsh. "Whatever, shorty." I replied and left.

I didn't go back to the underground. Everything was better on the surface and everything was ripe for the picking. I even managed to steal a pair of purple boots from the rich snobs behind Wall Sina. That was my best day for thievery. Sometimes, I try to tempt men with my body. It's fun messing with those pathetic people. On occasion, I wonder how Aiden's doing. But knowing him, he's just fine.
