She was previously a manager of a trans pub in Roppongi called "Tropical Fish" (that was located at Dogenzaka, Shibuya), which she had to abandon then. It is her dream to re-open the pub if she gets to move to Atlas, however, when Miiko won the lottery to Atlas instead, she gave up that dream.
Before Momoko transitioning, she was a well-known Judoka . In the anime, her weapon of choice is a whip that is coiled around her arm until she activates and uses it. She has a liking towards men, and is displayed attacking them through the use of an uncomfortable encounter for the soldiers. She has high athletic abilities, combat efficiency, as well as notable beauty.
