I'm look into reading ViviD and Force, the two sequel manga to the StrikerS manga, and I am wondering: what differences are there between the three anime seasons and the three related manga that could affect the reading of ViviD and Force?
Nothing! The aforementioned manga provides minor additional background for fans. This includes:
- Magical Girl Lyrical Nanoha MOVIE 1st THE COMICS
- Magical Girl Lyrical Nanoha A's
- Mahou Shoujo Lyrical Nanoha StrikerS THE COMICS
The remaining manga continues with an unique story:
- Mahou Shoujo Lyrical Nanoha ViVid
- Mahou Shoujo Lyrical Nanoha Force
The former is a carefree spin-off focusing on Vivio (but fun!), while the latter continues Nanoha's story.
