Prologue

A cloaked female figure in black traveling upon the great sights of the world outside of her home had pondered among the dust of the blowing winds. Behind the figure, remained a team of people whom she called her allies. "The world will forever be a world of filth, darkness, inhumanity, and cruelty. Only justice prevails." She looks upon the walls ahead of her with eyes glowing of familitary. The place she called home, she now has returned.

"Beyond the walls of the districts lie devouring, blood thirsty, abnormal creatures of existence that will destroy us. I've gone this far from here to gather my team of humanity's strongest members to slay these foul beasts."

She looks back at her team as they nodded sensing a dangerous threat nearby. With gear attached to the sides of their hips, they fly into the air as a wire hits the side of the walls. The threat revealed itself as a giant beast that devours an innocent human soul.

"I've slayed countless Titans with a team of allies I once knew. They're all in peace now, living a happier life. But I'm still here, fighting for humanity's greater good."

The cloaked figure gave the order as she and her team surrounded the monstrous titan slaying it down with blades of fury until it had been cornered enough to be slain into it's weak spot.

"These titans were once a key to finding an enemy I once quarreled with. I had to do it for the better no matter who or what I betrayed. It was a bitter fight until the end. I still remember the pain of my past. Seeing the lives lost, and my comrades fall, I still fought for them. "Wanted Dead or Alive", that was who I was. I was not just a soldier, but someone else. Someone who joined a rebellion." The figure had prepared her weapon drawing her sword meant for killing.

"We are fallen soldiers. We will forever be, the Wings of Fire." And she slowly jumped high into the air hitting the titan's weak spot as it dissolved into nothing but steam and bone.

"Harry! Harry! Harry James Potter! Wake up you idiot!" shouted a young girl's voice.

"Huh? Hermione?" Harry blinked as he sat up yawning.

"You had another dream doofus," the boy next to Hermione teased as Hermione glared at him back.

"Ron Weasley!" Hermione flared.

Harry rubbed his eyes as he yawned slowly stretching. It was a breezy late afternoon as the three young nine year-old children laid together under a shady tree of shelter.

"So, what did you dream about?" Ron asked curiously. Harry only stared up at the sky thinking about that cloaked figure he saw.

"I don't know," Harry replied straightening his messy hair into place. He thought about that figure in that dark cloak. The female figure and how she jumped up high, swung her sword, and slayed the titan with no expression of fear. "You guys don't think titans are ever going to barge in here and wipe out the human population, right?"

Ron and Hermione glanced at each other and back at Harry like he was out of his mind for bringing up such a nonsense, out of the question topic.

"Snap out of it Harry! They're not going to barge in and eat us up!" Ron hissed suddenly feeling paranoid about the walls that surrounded their district.

"Besides, those walls were built with magic. There's no way a titan would be able to destroy it," Hermione added. "Think about it, we're a middle class district, District 5 of Wall Godric. He was a strong and wonderful founder and he got his name for this wall."

Hermione was very fond of the history of the districts. Even if people made fun of her for being intelligent and knowledgeable for her age.

"Interesting," Ron replied.

"Thank goodness this district allows muggle borns. The upper district and the capital of the empire doesn't," Hermione frowned.

These three young children didn't know the secrets that lied within the upper district. And it was best not to find out what they were up to.

"Pffft. Screw the upper district. Dad always comes home complaining about how the upper districts get everything they oh so desire. Whoever is the ruler of this empire is nothing but a scoundrel," Ron pouted kicking a pile of small rocks.

"I don't know what lies in the upper district. I rather not find out. I heard the people there aren't very fond of bloodlines like us," Hermione continued on.

It was true that the upper districts were mostly upper powered half-blooded magic folk and pure bloods. The ruler of the empire simply requested that several lower ranked half bloods, muggles, or purebloods not interested in magic, stay away from the walls of the upper districts.

"Hermione's got a point. But as I was saying…" Harry started still thinking about the foul beasts that roam without intelligence outside the walls.

"Well, maybe it's because you're still traumatized about….you know what….." Hermione said as Harry shook his head in disagreement.

"No. It's not that I swear. Bloody hell, how many times do you have to keep bringing that up?!" Harry snapped.

"Hermione has a point you know. It's not like you call your aunt Mum," Ron insisted as Hermione nodded in agreement.

"Shut up! She's the only family I've got!" Harry snapped once more.

Eight years, only eight years ago, an evil wizard known as Voldemort was a threat to the nation. At the time Harry was a young baby, his mother, Lily Potter was the only one raising him since James Potter had died in the military in the scout regiment. He was eaten by a titan leaving Lily Potter to raise Harry on her own.

Not too long after, Voldemort had come to Lily's home going after Harry Potter due to a prophecy that he believed will give him great power if he kills Harry. As Lily shielded Harry to protect him, she ended up dying in the process. Voldemort went after Harry next attempting to kill him with a killing curse, but that only made Voldemort vanish leaving Harry with nothing but a lightning scar mark.

His mother's sister, Petunia Evans, took him him in raising him as if he were her son. She had suffered a horrible life losing the man she loved, and later, her child due to an accident. She made her nephew and herself the happiest they could ever be.

"I really don't remember who my father was, but I do remember my real mother," Harry replied. "But I'm not really dreaming of that. Really," Harry replied.

"Yes, but even old memories can come into the light and hit you like you've drowned in the river."

….

"Come on Lita, you've got to see this!" said a young girl's voice as a young girl with black hair and dark blue eyes stared at her friends while having her mouth stuffed with bread.

"Stop being a food maniac and come and see this!" added a boy's voice.

Lita got up running towards her friends Allyson and Frederick to see what they want from her.

"What do you want?" Lita half grunted.

"Stop with your grumpy tone! You make it sound like you don't want to see this!" Allyson chuckled.

"This outta turn your frown upside down!" Frederick added.

"Yuriko! Come, let's go see something," Lita called to a younger and smaller girl with blue eyes.

"Big Sister! We were just in the middle of eating!" Yuriko exclaimed.

"It is cute that she calls you Big Sister. It's sad you two aren't related at all," Allyson said.

Yuriko was only a seven year-old girl in emotional trauma. She was neglected and treated like she didn't exist in her household. She did have a biological older sister who treated the worst out of her. She mostly lived her life outside of her home until a seven year-old Lita found her in an alleyway when she was five. Lita had offered her some bread and the two became attached to each other like sisters. Although Yuriko wasn't taken in by Lita's family, she still lived a happy life outside her home. She and Lita would go around stealing food from markets in order to feed mostly her.

"Well, my parents don't really want to take in anyone else besides me. Hanji-Mama and Dad are fine with only me," Lita replied.

"Aren't you your father's girl?" Allyson smirked.

"Hanji-Mama technically found me first," Lita grunted in annoyance. It was only nine years ago since Lita was found in the woods alone. The commander of the Survey Corps, Hanji Zoe had found her before anything worse could've happened. She later became the adopted daughter of humanity's strongest soldier, Levi Ackerman. All because Hanji begged him to raise her since Lita had no one else that would take her in.

"You're still Ackerman's daughter," Frederick implied.

"Whatever," Lita grunted thinking she was also technically adopted. She stood there for a moment thinking as if she was remembering something that had hit her.

"You look like you're paranoid about something," Allyson pointed out looking at Lita's expression.

"Did you have that dream again last night?" Allyson sighed.

….

"I'm bloody hungry," Ron groaned. "I forgot my money at home. Blimey I'm not walking all the way there!" Ron grunted as his stomach grumbled to the fresh smell of bread.

"Honestly Ron, you are very responsible," Hermione complained.

"I think I might have some," Harry replied reaching into his pocket for some change. His ears light up as soon as he heard a commotion going on from not too far from here.

"Heh heh! Look at this freak!" shouted a boy as he kicked another boy.

"Fred! Let go of me!" shouted a girl's voice as two other boys held her back.

Harry, Hermione, and Ron all rushed over to see the commotion as part of the villagers also gathered around to see what was going on. Apparently, three sons of the town drunkards were beating up the poor Frederick Anderson and stopping Allyson Myers from trying to save him.

"Let me give those losers of piece of my mind!" Harry growled as he tightened his right fist into his left hand.

"Stop it Harry! It's not worth it!" Hermione shouted as she and Ron held him back.

"But...that kid...needs help!" Harry growled as he tried to pull himself out of Ron and Hermione's grip.

Suddenly, Harry felt a sudden force brush right beside him. He watched as a girl elbowed the bully out of the way and shoving him into the ground. He brushed off the dirt as he looked up to see a grim face of dissatisfaction looking down on him. He looked back up and shoved the girl onto the ground as he hit her a couple of times until he realized who it was.

"Argh! It's Lita! Let's get out of here!" shouted the bully as he and his friends took off into the other direction.

"That's what you bloody get you damned losers!" Yuriko shouted with victory.

"Thanks Lita," Frederick grinned while blushing in embarrassment.

Harry, Ron, and Hermione were speechless while the villagers were all chattering from left to right.

"Did you bloody see that?!" Ron exclaimed.

"She….she just took him out….." Hermione added astonished.

"That girl…" Harry said in his mind only staring at Lita as she helped Frederick get up. "She's the daughter of humanity's strongest soldier, Levi Ackerman. No wonder why she's probably that strong."

"The Survey Corps! They've returned from another mission!" shouted a villager folk as everyone gathered around the town line to create a path for the arriving soldiers.

"The Scout Legion. They're the branch in the military that goes to the outside world to slay those filthy titans! My dad was even in this!" Harry exclaimed as he and his friends ran to find a spot for the parade of soldiers. "My dream is to become a soldier in the Survey Corps so I can make my parents proud!"

Harry, Hermione, and Ron awaited the soldiers excitedly with smiles on their faces until they saw what truly lies within the duty of their band. Many were wounded fatally, blood dripping and staining the ground. Some that had gone earlier had never returned. The faces of fear, anger, horror, and hatred had hit them as they kept their eyes forward and continued moving.

"It's obvious isn't it? They've had another rough mission," Allyson said to Lita as she nodded in agreement.

"Sissy, I don't ever wanna join the military!" Yuriko quivered clutching Lita's arm.

"It's fine. You don't have to. But I will," Lita replied.

"Why?" Frederick asked.

"People like them die on those kinds of missions!" Allyson added shivering.

"Because, I want to see what it's like out there. Beyond the wall…" Lita said as Allyson and Frederick exchanged glances.

"Well, it's also my dream too," Frederick sighed in dismay. "But I'm frightened about those titans."

The four kids stood there as Lita turned around to look at the giant wall that surrounded District 5. The shadow that covered the sunrise and the Outside World beyond it. The wall that protects humanity from beasts of terror.

"That day will come. When humanity attacks on the titans, and slaughter them to the bitter end. We will see that world and claim as our own."

….

"I don't get it," Harry breathed anxiously in horror after witnessing such a horrible sight from the scouts. "Is it really that brutal to fight for humanity?"

"Of course it is Harry, open your eyes! You saw the horrified looks on those faces!" Hermione exclaimed. The three heard a shriek as they all turned to a weeping eld woman clutching down on the ground in tears.

"My poor son! He died a hero didn't he?!"

"ANSWER US COMMANDER ZOE! WHAT HAS HAPPENED ON THE MISSION THIS TIME?!" shouted a citizen. Shouts of people begging for answers came from left and right as they demanded an explanation.

"You and your damned job! Was it really worth it for our soldiers to die?!"

"My brothers Bill and Charlie are in the Garrison regiment. I betcha they deal with as much as the scouts," Ron added as the town started following the head commander for answers. "But anyways, I outta head home. See ya!"

"Me too," Hermione added, as she and Ron headed the direction they needed to head home.

"No wonder Mum is so freaked out and nervous about me joining the scouts," Harry thought as he started to head towards home. "It's so dangerous, even humanity will question for it's well-being."

"Watch where you're going brat!"

Harry snapped up as he laid his eyes on the girl who beat up those kids picking on her friend. Lita Ackerman.

"Uh…...s-sorry!" Harry stuttered nervously. Lita only glared back like he was the biggest problem in her way. "Damn, she's really scary up close!"

"Hmmf!" Yuriko pouted as the two turned in the other direction annoyed that Harry apparently was in their way.

"She's as cold as her father. That's what I heard about Captain Levi," Harry thought once more. Suddenly, that flash vision of his dream came to him as he gasped slightly thinking about the look of Lita.

"There's something about her…..her eyes…."

"Damn it! I think I'm going crazy! Even my friends think I am as well."

"How was your day Harry?"

Harry looked up to his aunt who set him a plate of food while she ran her hand through his hair.

"It was fine," Harry replied still thinking about his dream and the horrifying truth about the Survey Corps.

"Did you hang out with your friends today?" Petunia asked her nephew.

"Yeah. I had a dream and saw the Survey Corps return from their mission," Harry replied while staring down at his food. Petunia looked at her nephew knowing he probably just witnessed something horrible. More or less, she knows he wants to do something risky about it.

"And?" Petunia questioned.

"Everyone was…..yelling at them," Harry said as he tightened his fist. "They questioned their hard work and sacrifice…."

Petunia's eyes widened slightly as she suddenly remembered the horrible memory of Lily when she waited for her husband to return home from his mission. It was worse than what her nephew had just witnessed.

"They…..they tried…..and everyone….they….." Harry trembled as he felt his body heat up of anger and hatred. "I'll show them! I'll show them what it's like to fight and how hard they are trying!" Harry hissed, pounding his hand on the table.

"Harry James Potter! You're not going to get anywhere from acting like that!" Petunia scolded.

"But…..someone has to pay! Someone has to see….we're fighting for our humanity!" Harry hissed as he pounded his fist on the table once more. He then breathed in and out as he cooled down his temper and began eating.

Petunia sighed as she sat down and watched her nephew eat. "I love that boy as if he were my own son."

She smiled as she watched him eat as his green eyes reminded her of her beloved sister Lily. "However, I can't protect him for long. I know he will be a grown man soon. Especially since he's probably going to school soon. Oh sweet sister, I know you're not here in this world anymore."

Petunia got up to clear the table as Harry went upstairs to prepare for bed. "You are watching Lily. Please give him your love and protection. That's what you did on that fateful night."

"Man! Mom and Dad are going to kill me for coming home late!" Allyson groaned as she looked up into the sky seeing the tiny specs of stars twinkle in the moonlight.

"Mine don't mind me staying late. But I do have a curfew," Frederick sighed along. "More or less, Mum's going to scream at me for coming home all bruised up like this!"

"Sissy, you have a couple scratches!" Yuriko exclaimed as she pointed out a couple bruises on her arms and legs.

Lita sighed knowing her parents are going to question her. She was only after all, nine years old, but strong enough to go against people. She can tell they worry about her, yet they don't appear to think it is a big deal.

"It's nothing too important," Lita replied like it wasn't a big deal.

"Are you sure you don't want to come home with me tonight Yuriko?" Allyson asked Yuriko.

"I'm fine," Yuriko replied happily as if her life outside her home didn't matter.

"Whelp, goodnight everyone!" Frederick said as he and Allyson took off in the direction of their homes with Yuriko heading another direction to a place she lives under her house.

"Welcome home sweetie!"

Lita looked up to be greeted by her motherly figure Hanji-Zoe who had just returned home from a brutal mission.

"Evening Mom," Lita replied shutting the door behind her.

"You're bruised up and dirty….again," grunted her father figure Levi Ackerman.

"It's nothing important," Lita replied coolly.

"You got in a fight with those kids again didn't you?" Hanji sighed. "Honestly, they need to be controlled a little more. Did they beat up your one friend again?"

"He honestly needs to learn to defend himself. That brat's not going to survive being so weak," Levi replied.

"Levi, you can be a little harsh sometimes!" Hanji scolded.

"At least Lita knows how to teach those helpless children a lesson. Come on brat. Let's get you cleaned up," Levi sighed taking Lita to get cleaned off from the dirt and bruises she was covered in.

Hanji went to sit down at the table to get settled as she sat down thinking for a moment.

"Ever since that day I found her alone in the woods, crying….."

Hanji happened to be riding her horse with her soldiers the night they happened to stumble upon the young child. She and her group pulled over once they heard the sound of crying.

"Pull over!" Hanji ordered as her crew hurled over to listen to that sound of crying. Hanji lept off her horse to look around for the source until she stumbled upon a crying baby that had been left by a tree alone in the wilderness. Hanji bent down the pick up the child and comfort it.

"The minute I picked her up, I felt such a strong bond with her. She was the loveliest girl I had ever seen," Hanji thought to herself smiling as she watched Levi bandage up Lita's ankles and arms.

"We tried finding the parents of that child, but no one claim her as theirs. No one for some reason would take her in."

"Come on Levi! She has no one else! We should raise her!" Hanji grinned excitedly while holding the baby in her arms.

"You raise her. I'm not raising a helpless brat," Levi grumbled.

"Please?! I can't raise her without someone else. Come on, she's gotta have a father figure!" Hanji begged.

"Does it still sting a little?" Levi asked Lita who shook her head in response. Hanji smiled and blushed as she watched the moment between the two.

"It took a lot of convincing, but I eventually got him to say yes. Soon, we were together raising her like a daughter. And ever since that, Levi's been showing a little softer side."

Hanji smiled once more looking into the dark and radiant blue eyes of the girl she had raised. Strong and absent minded.

"I have a feeling that she reminds Levi of someone. And another where she might be someone significant in the future. It's only been nine years since we've found her, meaning there's still a lot more to learn about her. Oh Lita, what will become of you in the future?"
