Iba has a distinctive hair cut and wears black sunglasses with his standard Shinigami uniform. He collects sunglasses, his main source being Gin Tonbo, the same shop where fellow Lieutenant Renji Abarai purchases his goggles. He also smokes and carries his Zanpakutō as a small blade inside his uniform. He has a large tattoo on his back consisting of a cat on fire and the kanji shōfuku (inviting luck). These features, plus his informal style of speech, are all strongly reminiscent of a typical yakuza.
