It’s little surprise after the success of the two theatrical Magical Girl Lyrical Nanoha movies that a third film has been announced: Magical Girl Lyrical Nanoha Movie the 3rd: Reflection. What’s unusual, however, is that while the first two films were retellings of the first and second seasons, respectively, the third film will be entirely original. The third season is the longest, and takes place after a significant time skip, so it might have presented some problems, so I guess this is the equivalent to the filler arc in manga adaptations, or a tie-in movie that doesn’t actually affect the plot (not that those are a bad thing: the tie-in movies for Ranma, DBZ, Yu Yu Hakusho, and Digimon were some of the best animation in their franchises).
In addition to this announcement, there’s also news of two new Nanoha manga which will be running in Comp Ace starting on April 26, joining Magical Girl Lyrical Nanoha Innocent for a total of 3: Magical Girl Lyrical Nanoha Material Musume -Innocent- and Magical Girl Lyrical Nanoha ViVid LIFE -Inter Middle-. This will complicate keeping up with the already pretty complicated metaseries a little!
