For those who haven't listening about the SoundStage X.

StrikerS Sound Stage X (The Nanoha Drama CD)

two-disc Sound Stage set three years after StrikerS that excluded everyone introduced before StrikerS (with the exception of minor character Mariel) and revolved around a new incident that the heroes must handle. What appreared to be an ordinary Serial Killer case that Enforcer Teana was investigating turned out to be something more sinister as ancient texts that spoke of the undead Super Soldier army of Mariage led by the Dark King Ixpellia are uncovered together with the identity of a terrorist named Toredia who planned to use them. With the threat of a Zombie Apocalypse looming over the horizon, Subaru and friends must battle the Mariage, and locate both Ixpellia and the mastermind behind this latest terrorist attack before it's too late.
