Each ancient Princess Pretty Cure has their own castle in different parts of the kingdom. This also erected a new castle where the fourth Princess Perfume is hidden. The castles have a respective symbol on the top that resembles those found on the dial of the Music Princess Palace. They each also have a rainbow-like arch coming out of the top that connects to the main castle, but since Dys Dark took over, the rainbows have disappeared.

A few years before the start of the series, Hope Kingdom's princess, Towa, went missing. This caused great despair to the people for the princess is the kingdom's very symbol of "Hope". One by one, the citizens fell into despair and their dreams got locked away in the Gate of Desperation. The devil known as the Zetsuborgs, which are born from caged dreams, were then scattered throughout the kingdom. The princess was actually tricked by the darkness into believing the darkness could make her a Grand Princess. The Darkness than grew so strong that it took the form of Dyspear, the Great Witch of Despair and the Ruler of World. She then created Dys Dark, an organization that aims to spread despair throughout the world. Together with her commanders, the Three Musketeers, they managed to invade the Hope Kingdom and secured its castle as their base. Dyspear intended to destroy the twelve Dress Up Keys, which is Hope Kingdom's last weapon against her. The Dress Up Keys acted on their own and escaped to the human world. Prince Kanata, Hope Kingdom's prince and Princess Towa's brother was the only resistance against Dys Dark's forces. He sent the Royal Fairy siblings Puff and Aroma with the Princess Perfumes and the Princess Lesson Pad, to the human world to look for the new Princess Pretty Cures.
