Mira is also an American TSF engineer and researcher. She became romantically involved with Takamura Masatada during their time spent together at the Akebono Project, but later left him without a goodbye upon discovering of she was pregnant. Mira cut ties with Masatada because she knew the political scandal that would occur with someone of his noble background having an affair with a foreign woman and having a child outside of wedlock, and so to save Masatada from shame she returned home and became a recluse from her previous life and focused fully on being Yuuya's mother.
