Fitting of an assassin, Gin is deathly quiet, seldom speaking, and pairs her silence with either indifferent or serious expressions. Similar to her brother, Ryunosuke, she's quick to lash out when provoked. Gin has dark gray eyes and long black hair. As a mafioso, she keeps her hair in a spiked bun, leaving sections of shoulder-length hair down. Most of it falls to the right side of her face, whilst a strand falls over the middle.
