Psikyo

was a Japanese video game developer and publisher known for its shoot 'em ups. It was founded in 1992 by former Video System staff who worked on the Aero Fighters series. Psikyo was mainly an arcade game developer, and ported some of their games to home consoles as well.

Psikyo was acquired by X-Nauts in 2002. In 2003, it was reported that Psikyo was shutting down. Shortly afterwards, X-Nauts stated this news was wrong, and that games would continue to be developed by its Psikyo division. In 2007, Psikyo programming veteran Keiyuki Haragami started a company called Zerodiv to handle distribution of Psikyo's catalog. In March 2019, Zerodiv was acquired by City Connection, but in February 2025, Edia, the current owner of Telenet Japan IPs, purchased Zerodiv from City Connection by a value of one million yen.
