Chairo (written in Japanese as 茶色, meaning "brown") is one of the Japanese Super Mario Flash team members and also the developer of Super Mario Flash 2 Version C, as well as a co-developer of Super Mario Flash 3. He is not active as Hiro, but he is the first known individual (besides for Pouetpu) to successfully add new features to Super Mario Flash without causing new glitches.
Chairo's website is cha.webcrow.jp.
