Myao

Myao is a traveling martial artist from China who, while she has a definite sense of justice, tends to leap into situations with little thought as to the consequences. She is basically a country bumpkin, described as having "the heart of a saint and the brains of an empty liquor bottle." She met up with Ran on her travels. Since then, the two tend to bump into each other. Often it's Myao who pays for Ran's food and sake. (Source: Absolute Anime)
