In a desperate bid to save her father and the dying world of Eltria, Kyrie Florian finds herself betrayed by her closest friend, Iris.

Amidst the chaos and fierce confrontations, Nanoha remains steadfast, using her magical abilities to assist those in distress and protect the world from the shadows that loom ever closer.
