Full Moon wo Sagashite, Mahou no Tenshi Creamy Mami Recommendations
These two anime feature a young girl who can transform into an older, beautiful idol with the help of two magical creatures. The girls in both have certain restrictions on their powers. The style of the anime has a happy feel, but Full Moon includes a touch of tragedy.
Both series has the young girl, who by magic transforms into beautiful teen who eventually becomes an idol sensation. Full Moon is a little darker and more tragic than Creamy Mami, amd Creamy Mami is more of a magic girl than Full Moon, who never performed any magic. Creamy Mami is fun and lighthearted, with some dramatic moments.
The background of the protagonists is pretty much different, but in some ways, the heroines are quite similar.
Both are young girls, who change into older forms to become idols.
Both have a somewhat chaotic manager.
Both have a rival in their idol form, who is on good terms with the younger incarnation (more extreme in Full Moon, where Madoka regards the protagonist as both best friend and biggest enemy)
Both have 2 magic companions, male and female (animals in Creamy Mami, with animal features in Full Moon)
So if you watched Full Moon and you are looking for a similar hero in a more light hearted setting, you
