A nameless knight in black armor drifted through a dead world for an unknown duration before setting foot on an island where time has stopped. There he found a mask rumored to change fate. Putting it on teleported him somewhere startling: a noisy city blooming with flowers and grass. Fragments of memory surface that feel like dreams. He meets a slave girl named Air. Together they begin a journey neither of them chose. As they travel, the knight slowly recovers who he was and why he came here. An action RPG built around recovered identity.
