Magical Girl Lyrical Nanoha: Reflection

Magical Girl Lyrical Nanoha Reflection is the third theatrical anime film in the MGLN franchise. Unlike the previous two films, it will not adapt an existing story (such as StrikerS) but instead feature an original storyline, taking some cue from the plot of The Battle of Aces and The Gears of Destiny but adding original storylines and characters, as well. It is the first part of a two-part story, with the second part titled Magical Girl Lyrical Nanoha Detonation. (themoviedb)
