Kozakura speaks in a candid fashion and detests Toriko's officious behavior around her. She, however, tolerates Toriko's behavior as she goes out of her way to search the mysterious land of the Otherside, in hopes to find her friend Satsuki. Kozakura had explained that her serotonin transport gene is short (prone to get scared easily), she avoids going to the Otherside as much as possible leaving Sorawo and Toriko to do the field work instead. Despite her blunt and insensitive attitude towards the pair, she cares and looks about them, somtimes showing concern whenever they go to the Otherside. She is a petite young lady with very long hair white. She often dresses in an oversized plain shirt and dark-colored shorts.
