Question: is levi related to mikasa?
Answer: He's Mikasa's uncle by her mother. "Attack on Titan" creator Hajime Isayama doesn't reveal Levi's age but he did say Levi is “surprisingly old.” Also, Mikasa's father was tall and blonde—nothing like Levi. ... Levi and Mikasa are just both named Ackerman and have no relation whatsoever.
