My Blank Mother and Her SSSS Identity

Ten years ago, Shawna Stewart was left in the mountains and then taken in by a fool, Cherry. After being bullied for years because of Cherry, Shawna ran away and met her real mom Mindy Stewart. Mindy couldn't accept her daughter's adoptive mom was a fool, so she tried to take Shawna away. However, they accidentally found out that Cherry turned out to be the War Goddess, the Phoenix Legion's former commander.
