Muichiro is a tiny cat with a size of half of a normal sized mirror. He was a 14 years old Mist Hashira before a vial came flying towards him and got turned into a cat. Muichiro still has his attitude of being kind, calm, smart and silly sometimes. He has his long side hair with the colors of black to pale turquoise. His eyes are also turquoise with a lighter shade on his bottom iris part. His whole body is black except his tail which has the color pattern of his hair.
