Mia is a supporting character in the anime Captain Earth. She serves as one of the operators aboard the Tenkaido, the space station operated by the organization Globe. Physically, she is a young woman with blonde hair and blue eyes, and her uniform is a yellow variant of the standard Tenkaido outfit. Her age is listed as 26. Little is known about her background beyond her role as an operator, but her personality is suggested through her interactions with other characters. She appears to have a romantic interest in Teppei Arashi, a key member of the Midsummer's Knights. In episode 18, she asks another character, Rena, whether Teppei has a boyfriend, and later tells Teppei to come back to go swimming again, indicating a friendly and possibly flirtatious disposition toward him. Her motivations are not deeply explored, as she primarily fulfills a supportive function within the Tenkaido team, monitoring and assisting operations. Her relationship with Teppei is her most notable connection, though she also interacts with other station personnel like Rena. Mia does not undergo significant character development over the course of the series, and she has no special combat or supernatural abilities; her role remains that of a background operator.
