Pinky finger.

Pieck Finger (ピーク・フィンガー Pīku Fingā?) is an Eldian who served as one of Marley's Warriors and possessed the power of the Cart Titan.

Pieck is a short young woman with long, disheveled shoulder-length black hair, a Greek nose, and relaxed dark brown eyes. She wears a white blouse, a long trench coat, a skirt that reaches her ankles, and black lace-up boots. She also wears the Eldian armband on her left arm, as required of all Eldians under Marley's authority. Since the end of the Marley Mid-East War, Pieck has been walking with a crutch, having lost some ability to walk upright.

Pieck is shown to be somewhat sweet and kind, consistently caring about her fellow Warriors and Warrior candidates. She is incredibly intelligent, able to quickly deduce a situation. When the Warriors were discussing the prospect of using the Tybur family to assist in their operations, Pieck was able to quickly figure things out, and Zeke Yeager implies this happens quite often.[11] However, Pieck is usually shown to be quite eccentric and easygoing. During the train ride to Liberio, Pieck gladly gave Colt Grice a drink when he asked for one, which led to him getting drunk and leading the other Eldian soldiers in a chant in favor of Gabi Braun. As a result of constantly being in her Titan form, Pieck has developed the habit of walking on all fours when few people are around, stating that it feels more natural and even curling up on a sofa like a cat; she is still capable of walking upright, although she occasionally requires a crutch to do so. She has shown loyalty to Marley since childhood, fighting well for the country's interests, but actually wishing to have her people released from the persecution they face every day. She is also very concerned about the future of the Eldian race as a whole, recognizing that the world wants them gone and fearing that they will no longer be useful with the increasing advancements in technology. Furthermore, her main reason for becoming a Warrior is to get her ill father money for his treatment.[17] She did not display much resentment towards the inhabitants of Paradis Island and criticized her superiors' strategy.

Pieck grew up in the Liberio Internment Zone and lost her mother early in childhood; seeing that her father had fallen ill and would not survive long without proper medical care, Pieck joined the Warrior program as soon as she was eligible. After performing well enough to be selected to inherit one of the Marleyan Titans, Pieck was able to secure her father the treatment he needed. Despite this, Pieck recognized that her father now had a sadness in his eyes after learning that she would only live for thirteen more years due to the Curse of Ymir. Wanting to show her father that Eldia had a bright future ahead, she decided to try any way possible to free the Eldians in Liberio and Marley before the end of her thirteen years. After Pieck inherited the powers of the Cart Titan, she was kept in Marley along with Zeke Yeager as a deterrent to enemy nations while the other Warriors (Reiner Braun, Annie Leonhart, Bertolt Hoover, and Marcel Galliard) were sent to participate in the Paradis Island Operation in the year 845.

Long ago, humans were just food for the titans. Until humans built three giant walls around their country. Wall Rose is the second outermost Wall following Wall Maria. It was breached by the Colossus Titan 5 years after the fall of Wall Maria, but the breach was later sealed by military efforts of the three branches and help from the Attack Titan. Wall Sina is the innermost Wall protecting the kingdom where the king and other civilians reside. The cities of Wall Sina are protected by the Military Police serving under the king. The underground is poorer and more prone to criminal activity. Wall Maria is the outermost Wall of the human kingdom. Like the other Walls, Wall Maria is approximately 50 meters in height. Five years ago, it was breached, after a century of peace and prosperity, and was lost to the Titans. The human military against the Titans is divided into three divisions: the Survey Corps, which explores the areas outside the Walls; the Garrison, which patrols and maintains the Walls, preventing Titans from entering the Walls in case the gates are breached, primarily to delay and distract the Titans; and the Military Police, high-ranking soldiers who serve as personal guards for the King and maintain order within the Walls. The Survey Corps (調査兵団 Chōsa Heidan?) was the branch of the Paradisan military most actively involved in direct combat with and study of the Titans. Due to their constant expeditions, the Survey Corps' soldiers were the most proficient in the use of the 3D Maneuvering Gear and the Anti-Personnel Spatial Maneuvering Device. Despite little success from their activities, the members of the organization still symbolized the "hope of humanity", and their insignia was known as the "Wings of Freedom". The Survey Corps' goal was to someday change the world and take back what was taken from humanity.

Garrison (駐屯兵団 Chūton Heidan?) is the most numerous, but also the least qualified (except for elite units) branch of the military. Due to the high mortality rate of the Survey Corps and the high competition for recruitment into the Military Police, people most often prefer it. The main task is to protect the Walls during an attack by the Giants and the subsequent evacuation of the civilian population. Secondary: organizing order, patrolling, repairing defensive structures. In the battle for Trost, the Garrison fighters not only defend the walls, but also independently clear out the captured areas. It was they, along with the cadets, who participated in the defense of Trost, only then the Survey Corps cleared out the city. The Military Police (憲兵団 Kenpeidan?) is the most prestigious branch of the military. This is because their job allows them to live within the inner walls, in safety. The Military Police have a lot of resources, and their power is greater than that of the Garrison and the Survey Corps. In reality, the Military Police have a complete lack of supervision and discipline, abuse of power can be seen everywhere, they have a bad relationship with the Garrison and almost hateful with the Survey Corps. Only the top ten cadets can get into this branch of the military, but judging by the conversation between Boris and Hitch, there are other, illegal ways to get into the police. Most titans are pretty stupid, but despite this, killing even one titan is quite problematic. Only one weak spot has been discovered in titans - the neck. If you cut even part of a titan's neck, it dies immediately.
