Iba has a distinctive hair cut and wears black sunglasses with his standard Shinigami uniform. He collects sunglasses, his main source being Gin Tonbo (銀蜻蛉, The Silver Dragonfly), 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. Seventeen months after Aizen's defeat, Iba has a fuller moustache and a new scar above his left eye. His hair is also more shaven, with three hairless lines running through it.
