- Age: 16,
Ranka is a petite, lively and cheerful (although naive) teenage girl with green hair. She suffered from amnesia as a result from witnessing the destruction of the 117th Long Distance Research Fleet in which her biological family perished. She is one-quarter zentraedi, which gives her the ability to have her hair move on its own according to her feelings as well as an above-average resistance to the vacuum of space(her hair is normally green, but turns blue when she's very depressed). As the adopted younger sister of S.M.S. ace Ozma Lee, she initially attends an all-girl's high school at the urging of her brother while working part-time at the Chinese restaurant "Nyan-Nyan".She later transfers to the Mihoshi Academy to facilitate her singing career after being discovered at the Miss Macross contest and an ensuing movie. Ranka started off as a huge fan of Sheryl Nome as she loved singing since her childhood and had dreamt of becoming a singer, which gets realized thanks to Sheryl's compliments who gave Ranka more self-confidence and Micheal's push who lead her to be known for the first time at the shopping mall. She develops a crush on Alto Saotome, especially after being rescued by him when the Vajra first attacked the Macross Frontier fleet.
In the second part of the TV serie, as Sheryl's gets "forgotten" little by little due to Grace's plans, Ranka's popularity grows up.
It is revealed that she has a deep connection to the Vajra as her songs confuse them and she feels severe pain whenever large amounts of Vajra are killed in her vicinity. The exact nature of this ability has been explained as the result of her mother's exposure to the "V-Type" infection during pregnancy. Ranka is referred to as the "Little Queen" by Grace O'Connor, suggesting that her relation to the Vajra may be more than it seems.
In episode 21, she leaves the Macross Frontier fleet (along with her bodyguard Brera Sterne) while trying to deliver her Vajra pet "Ai-Kun" to the rest of its species. She and Brera eventually find the planet of origin of the Vajra. Ranka is captured by them just as she recalls her past and realizes that Brera is her biological brother. While being held on the Vajra planet, she realizes that everything that happened to the 117th fleet was her fault because her singing attracted the Vajra. Grace O'Connor manages to manipulate Ranka into compromising the Vajra fold communication network, allowing her (Grace) to send the Vajra against the incoming Macross Frontier fleet during their final battle. However, with the help of Alto and company, she manages to break free from Grace's influence and rallies the Vajra to side with the Frontier fleet to defeat Grace. In the final scene, she is seen telling Sheryl that she will not allow herself to lose, whether in singing or in love.
