Hilda, the medic aboard the spaceship Muze, is romantically involved with Captain Sara, the vessel's commander. She possesses a Caucasian complexion. After an assault by Flair, an alien entity disguised as a human survivor, Hilda suffers severe psychological trauma. This trauma erupts as uncontrollable laughter while she brandishes a firearm erratically, discharging it towards Hikari and Yuri. Her shots damage a window, causing explosive decompression that violently ejects her into the vacuum of space, where she dies.
