Keita "Fuudo" Ai (ja: 阿井 慶太) is a Japanese fighting game player. He is a two-time EVO champion, having won Super Street Fighter IV: Arcade Edition in 2011 and Virtua Fighter 5 in 2012. In Street Fighter IV, Fuudo was known for being a masterclass in spacing and stage control with this Fei Long, often displaying incredibly solid fundamentals and near perfect execution.

In Street Fighter V, Fuudo has proven his versatility as a player by switching to a mix-up heavy character in R. Mika. Although NuckleDu won more championships with the character, Fuudo was the originator of many of the setups and mix-ups that all R. Mika players adopted. Despite being one of the best players in the world and consistently placing incredibly high in every season, Fuudo often struggles to find victories in big tournaments. Still, Fuudo has more than solidified himself as the world's best R. Mika player.
