ツメ (Tsume, lit. Claw) is the second wolf to be introduced in the Wolf's Rain series. Rough and self-reliant, Tsume is a strong fighter who keeps his true feelings to himself. He only joins the others out of boredom and does not, initially, believe in Paradise to exist. Though he frequently quarrels with Kiba over the course of their journey, he eventually comes to believe in Paradise as strongly as Kiba does.

Wolf's Rain
The world is slowly dying... In a post-apocalyptic future where humans live in large domed cities surrounded by wasteland, wolves are believed to have been extinct for 200 years. But some wolves still remain. These wolves live by disguising themselves as humans to survive. Wolf's Rain is the story of four wolves, Kiba, Tsume, Hige and Toboe, who will follow the scent of the lunar flower on a quest to find paradise.
