Twinkle Star Knights is Bishoujo RPG based on the Japanese visual novel Twinkle Crusaders developed by Lillian and released in September 2008. The project is supervised and planned by game artist Rei Kannagi from Creative Team Kuma-san.

Set in a world trembling in fear of a calamitous disaster known as the Recreate, and the sudden emergence of menacing monsters. In response to this crisis, the state and Ryusei Shikoku collaborate to establish two academies, Ryusei Academy and Shinsei Academy. These institutions are designed to train Star Knights, who are hoped to counteract Recreate.
