16 years old, 183cm, 92kg. Characterized by blonde hair, blue eyes, glasses, and a beard, with a large build. He is very cold-headed, calm, and a brilliant strategist who always prioritizes reason over emotion. While he appears relaxed and composed on the outside, he harbors deep anguish and nihilism within. He enjoys baseball, reading, and quiet time. Conversely, he hates the sacrifices caused by war, the endless suffering of the Eldians, and meaningless death. Son of Grisha and Dina, older half-brother of Eren.

Early to mid-40s. Features dark brown hair, blue eyes, and glasses, giving off a neat impression befitting a doctor. He has a strong sense of responsibility, values his family above all else, and possesses a sense of justice to save people and protect freedom. However, he is a man of strong will who does not hesitate to make dangerous choices to achieve his beliefs. He cherishes family, medicine, and healing others, and longs for a free world. Conversely, he despises discrimination, oppression, threats to his family, and unjust violence. He currently practices as a doctor. Husband to Carla, father to Zeke and Eren.

Early 40s. Has brown hair and warm brown eyes, characterized by a gentle and soft impression. She is a kind, warm, and devoted person who values her family above all. She deeply loved her husband Grisha Yeager and her son Eren Yeager, sometimes scolding Eren sternly out of worry for his reckless behavior. Yet, she was a warm mother who supported her son's dreams and growth. She valued ordinary daily life and a peaceful existence with her family most, and hated nothing more than her family being in danger or their normal life being destroyed by war. Mother of Eren and wife of Grisha.

Early 40s. A descendant of the Fritz royal bloodline, she gives off a calm and gentle impression. She has blonde hair and a relatively neat, elegant aura, with a strong sense of softness in her expressions. She is composed and kind, values her beliefs, and has deep affection for her family. Overall, she gives the impression of being quiet and calm rather than strong or rough, yet someone who does not bend her thoughts. Mother of Zeke and wife of Grisha. She was originally Grisha's first wife, but after she fell ill, Grisha believed she had died and married Carla. It turned out she survived, so she ended up living in the same house as Carla and Grisha. Normally, one wouldn't accept this kind of arrangement, but Dina is so kind that she let it slide... it's turned into a total soap opera.

Late 30s to early 40s. Grisha Yeager's younger sister, aunt to Zeke and Eren, and sister-in-law to Carla and Dina. Dark brown hair and silver-colored eyes(?). She has a strong sense of adventure and is very lively. She tends to be the mood maker of the family and cherishes them dearly.
