One hundred years prior to the beginning of the story, giant humanoid creatures called Titans (巨人 Kyojin?) have forced humanity to retreat into a system of concentric Walls (ウォール Wōru?) known as Wall Maria (ウォール・マリア Wōru Maria?, outermost), Wall Rosé (ウォール・ローゼ Wōru Rōze?, middle), and Wall Sina (ウォール・シーナ Wōru Shīna?, innermost). Inside these walls, humanity lived in peace for one hundred years, but in the beginning of the story, a sudden attack by a gigantic sixty-meter Titan and a smaller Titan covered in armor plates causes the outermost wall to be breached, forcing mankind to abandon the land between Wall Maria and Wall Rosé, which leads to famine and turmoil.
Little is known about the Titans, giant creatures that are usually between 3-15 meters tall with a few exceptions. The Titans instinctively attack and devour ordinary humans on sight. However, they apparently do not need to feed to survive, as they do not prey on other animals, even with the long absence of humans, and can survive by absorbing sunlight. They have hard skin and regenerative abilities, and can only be killed by a deep incision on the base of the neck. This weakness led to the development of the Vertical Maneuvering Equipment (立体機動装置 Rittai Kidō Sōchi?), allowing humans to navigate quickly in a three-dimensional space to access the Titans' weak point. Although it allows great mobility to a skilled user, it carries a large risk of overtaxing the muscles, requiring special physical conditioning and a sense of balance to master it.
Throughout those hundred years, generations of humans moved and passed, allowing the next installment of children to take over the new precautions of mankind. The walls were completed and mankind was deemed protected within this safe haven. Even though it would seem the walls would hold any Titan intruder, the fact was, that was never granted by anybody. With that said, a workforce of construction workers throughout the three walls were created, their main priority, enforcing the structure of the wall so that it becomes impenetrable by any Titan. Though it was deemed impossible, security measures must be taken to prevent the unlikely. Haines, eighteen year old male, son of Bridgette Techeira, was part of this construction crew. In order to make a little money and support his household, he had to do a dangerous job that would bring in the most dough. Being a construction worker meant hanging two titan sizes off the ground, meaning about thirty plus feet. A lot of workers fell during this time period, the harnesses weren’t the sturdiest even though the creation of the vertical maneuvering equipment had already been issued. That equipment was for government use only, meaning, soldiers of fortune that fought against these giant humanoid being day in and day out. It always seemed like these soldiers, regardless how well they were equipped, always lost their lives in battle. Titans were sometimes seen as immortal, frightening humanity to their pits beneath the ground. Those pits weren’t a metaphor; they are truly running underneath the three walls for possible refugee when necessary, but the strength of the Titans sometimes overpowered those pits. Now back to reality, reinforcing an entire wall of about unimaginable size was hard work, hard work that took years to accomplish. Through those years, just imagine how many people died not only building the wall, but having Titans at their feet during that time. When the wall was finally complete, it became one of humanities first triumph victory. This risk was taken by Haines every hour of every day. He worked long hours without breaks to eat or to rest. Resting would cause one to be fired immediately; there is always someone to replace you if you didn’t give it all you had. It was about five thirty in the afternoon as people of my generation would say; Haines was hanging from a thin, yet sturdy, rope. He placed the flat trowel on the wall, building a circumference of cement around the area he was working on. “Haines! Get your ass down her boy!” the boss yelled. The teenager let go of his wrote and quickly made his way down, pushing himself off the wall with every jump. As his feet finally reached the dirt beneath him, he untied the rope from his waist, allowing it to dangle from the top of the wall. “Yes sir?” Haines asked, not sure why the boss had called him down. “You were late this morning you know?” For a second, Haines wasn’t sure what the man was talking about, but suddenly remembered the entire situation. “It….I was helping my mother get to a doctor, she’s been sick for wee…” he was interrupted by an annoyed deep voice. “No excuses! You know this job is serious business. Go home! You’re dismissed for the day. I’ll let you know when I need you again” the manager said, walking away. Haines stood there for a couple seconds processing what had just occurred before him. His eyes squinted from the anger that started building in his chest. With that, he walked home, looking at nothing but the ground, cursing everything around him. “F*ck this place, I hate it. Why the hell is money always the most important thing” he murmured to himself, kicking a small stone, causing it to fly through someone’s window. “Oh crap!” Haines said as he took off quickly before anyone noticed him. Once he made it home, he made sure to knock before entering in order to not startle his sick mother. “Mother, I’m home” Haines’ voice echoed. The house was nearly empty. They weren’t wealthy at all; only things they owned were necessities, necessities to survive. Haines took the luxury of walking to his mom’s room to see if she was sleeping, due to there being no response. As he entered the room, there wasn’t anyone there. The bed was made, sheets completely straightened, but there was a note. “Dear Haines, I’m going to visit the doctors today. I may just stay there for the night, I’m not sure I can make two trips. Your mother’s getting old. (Signed) Mother.” After reading that, Haines threw away the letter and huffed angrily. “Stupid woman” he facepalmed as his veins popped a little, “How are we gonna pay those bills, I pretty much just lost my job!” He stood motionless for a while in attempt to loosen the aggravation of his thoughts, then left his mother’s room and took charge out the front door, locking up behind him. His hands were trapped in his pockets as he shoulders came forth to look as if he were hunchbacked. Haines was going to go to the doctors to make sure his mother had actually made it. She was a weak old woman now and she always needed assistance. It was strange that she took actual priority of doing something as risky as walking alone a few miles across town. It wasn’t like her; she would never put her life in jeopardy. “This isn’t my lucky day” he laughed. “It never is."
