Matamune is a character in the Shaman King manga. Matamune, who appears in volume 19 and 20, is not in the Shaman King anime. Matamune is a Nekomata, a type of cat spirit with two tails; he also carries around a pipe with him and wears a necklace with three bear claws (which later is owned by Yoh Asakura). He has served the Asakura family for a millennia, although he spends much of his time travelling the world. He professes to have seen everything, and is almost constantly reading books.
