Nights Of Azure follows Arnice, a half-demon knight tasked with protecting a childhood friend destined to be sacrificed to prevent an eternal night. Action combat blends melee attacks with a roster of summonable demon servants that fight alongside her.

Players battle through moonlit, demon-infested streets, forming bonds with Arnice's allies while racing against a ticking curfew each night. It's an anime-styled action RPG built around a poignant story of sacrifice and friendship.
