Another Ovid pilot who transfers in Madoka's class and joins the Jersey Club. Although she appears to have a slow-witted personality, she is actually sharp and perceptive. She will occasionally say "Understood" (かしこまり〜 Kashikomari~). Born on a Prison Planet, she views Villagiulio as an older brother and by his orders, she infiltrated the Pharos base to steal one of the Ovids, thus she ends up becoming the pilot of Vox Ignis, which she nicknamed Hupo. After being betrayed and abandoned by Villagiulio, Muginami finds herself a new place among Madoka and her friends. After Villagiulio's second skimish, she and her Vox took him and retreated into space. She returns in Season 2 where, after realizing she doesn't want to fight those she loves, rejoins the Jersey Club. Hupo is now equipped with a energy cape she uses as a shield.
Muginami is voiced by Ai Kayano in the original Japanese version who is notable for the voice of Inori Yuzuriha of Guilty Crown and Karen Strassman in the English version who also voiced Sui-Fēng of Bleach, Kallen Kōzuki of Code Geass and Aigis from the video game Persona 3
