As an assassin, Gin is silent and stealthy, described by Tachihara as being able to sneak behind someone and slash their throats in an instant. This was demonstrated when she snuck behind Higuchi and put a knife to her throat before she could notice.Fitting of an assassin, Gin is deathly quiet, seldom speaking, and pairs her silence with either indifferent or serious expression. Gin pretends to be a boy, using he pronouns, when in reality she is a young woman. She is Akutagawa’s little sister.
