Akko's Secret (2012)

In Himitsu no Akko-chan, the little girl transforms into an adult, while in Papa to Musume a daughter and her father swap bodies. The movie reminded me of this drama because in both a young girl works in a company with another identity and share their crazy innocent and refreshing ideas.

Both movies involve time traveling, but in Akko's Secret, the elementary schooler becomes her future self and.... wait for the surprise in the end! :D

Both magical girl genre, Akko’s Secret is based on old anime Kiki’s delivery service is based on old magical girl movie
I think you may like this one based on that.

it also has a magical girls theme and charming story of love and magic.
