Praying to Axia is a tradition that has been passed through generations. When it was Himelda's time to pray to Axia, she heard someone calling for help from inside the box. Without knowing its content, she opened the box. At that time, Phantom Empire were freed.

​Phantom Empire Invasion
After Queen Mirage and her allies were freed, they quickly invaded the kingdom. Every citizen was defeated and trapped inside mirrors, including the Queen and the King. They are being kept inside the throne room.

After the invasion, the whole kingdom was changed by Queen Mirage according to her preferences.

Himelda, unable to fight against them, fled to Pikarigaoka with her caretaker, Ribbon. They started their journey to retrieve the kingdom back.

The kingdom is being guarded by several Saiark and Choiark. Due to Queen Mirage's influence, they become more powerful inside the kingdom and the power of the Pretty Cure are weakened.
