Ginrummy is a Shinuchi[2] of the Beasts Pirates.[4] Ginrummy is a tall woman of slender build with white skin, barbie-pink colored hair, and light blue eyes. She wears very little clothing, limited up to two pieces of red-violet metal breastplated armor with golden spine-like dots and white fur covering her breasts around them, a red-violet thong, a pair of black gloves, black calf-length high-heel boots, small thin golden earrings on her ears, and an open black cloak with white fur and spine-like dots. She also has a pair of small, black horns on her head.[5] Ginrummy is a fairly cautious woman, having ordered her crewmates to retreat right after Sanji defeated Sheepshead instead of battling him and the other Straw Hats.[6] Additionally, she did not reveal to Jack that his minions had been forced off Zou, knowing his response to their failure would be harsh.[7] She seems to be less brutal and sadistic than many of her crewmates, having winced when Jack spoke about the various brutal and sadistic things he could do to Zunesha in order to kill it.[8]

Ginrummy reacted to Sanji's perverted nature by attempting to cover herself up, indicating that she is embarrassed by such people.[9] Ginrummy holds a high position in the Beasts Pirates and has authority as a Shinuchi, especially since some of the lower members of the crew followed orders from her during their search for Raizo.[6] Jack personally addressed her during his assault on Zou, also confirming her status in the crew.[4] One day after the battle, Jack left Zou to rescue Donquixote Doflamingo after learning of his defeat and capture, leaving behind some of his subordinates, including Ginrummy, to continue searching for Raizo.[14]
