Sasha's father. He speaks with a southern Marleyan accent. Before his daughter Sasha joined the military, they lived together in the village, where he struggled with her insatiable appetite and refusal to adapt to changing local circumstances. While understanding the importance of the traditional ways inherited as a native hunter, he is a person of character who can also consider social cooperation as a broad and realistic choice. He pointed out that his daughter's stubborn adherence to tradition might be due to her fear of facing others.

The government recommended he engage in horse breeding, and it seems he switched professions after Sasha left home. When Titans appeared within Wall Rose, he distributed horses to nearby residents for a quick evacuation and reunited with Sasha when he took in a child (Kaya) she had rescued. He praised his daughter's actions and growth.

In the Marley arc, he runs a ranch and takes in children like Kaya who lost their parents to Titans. He warmly welcomed Falco and Gabi, who pretended to be runaway siblings. Later, upon learning that Gabi had killed Sasha, he stated, "It is the responsibility of adults to bear the sins and hatred of the past," showing no hatred towards Gabi. After the Marley raid, he was concerned about Falco and Gabi, who had been separated from his wife.

After the "Battle of Heaven and Earth" concluded, he is depicted with a sad expression alongside his wife Lisa and others, in response to the Jaegerists' speech promoting military expansion and the enthusiastic crowd.

In the live-action film version, Sasha's father is already deceased, and his name remains unknown. Instead, her adoptive parents are her brother and sister-in-law (played by Indy Takahashi and Kanako Yamamoto), who are portrayed as degenerate characters who enlist Sasha in the military for money.
