Just a caveat about this recommendation. Not trying to be confrontational, just wanna be clear about expectations. It's a fine recommendation otherwise.Is Mahou Shoujo fine with you? If so, I will recommend Mahou Shoujo lyrical Nanoha series. The first two seasons in my opinion develop the story for Season 3. There is also a two part movie that cover what happen in between the end of season 2, and the start of season 3.
After Season 3, there is 2 spin-off series of the anime, although the characters in the first three seasons do make appearances too
The manga demographic is shoujo, so yes. Although for anime this kinda classification is a bit arbitrary because it is originally just used to define target demography than style/genre, but non Japanese public uses for genre rather than demographic.Does Bannana Fish count as Shoujo lmao
