Sasami 14: Mahou Shoujo Pretty Sammy

Sasami Kawai is now fourteen, and her secret life as Pretty Sammy should have continued alongside Misao as usual. This time, however, the problem is fundamental: Sasami can no longer transform into a magical girl, leaving the power she once relied on out of reach just as new dangers begin to appear.

A mysterious beast and a new magical girl enter her life while Sasami searches for the reason behind the lost transformation and wonders whether she can still protect others without the identity she has always depended on. Turning fourteen does not make her world simpler. Instead, it forces her to discover all over again what being a hero actually means.
