Magical Record Lyrical Nanoha Force

Six years after the catastrophic JS Incident, a young dimensional traveler named Touma Avenir encounters a mysterious and mute girl named Lily Strosek on the distant planet of Ruwella. When rescuing her, Lily bestows upon Touma an amulet granting him access to a new Device power. However, their actions inadvertently contribute to a destructive incident involving the Book of the Silver Cross, an ancient Belkan magical tome. The Time Space Administration Bureau launches an investigation, and the former members of Riot Force 6 are once again thrust into an interdimensional crisis, forcing them to confront a new and formidable threat.
