Psikyo (彩京, Saikyō) is a Japanese video game company started in 1992. Psikyo is an offshoot formed from the staff that created the Aero Fighters series for Video System. Psikyo focused on arcade games, mostly vertically scrolling shoot 'em ups and erotic mahjong games. The popularity of these arcade games led to them being ported to home consoles, and then ultimately to Psikyo developing games for consoles.Psikyo was acquired by X-Nauts in mid-2002.
