Sky Pretty Cure ~Rainbow Star~: Niji Hoseki no Densetsu / Transcprit

A long, long time ago, five powerful warriors were born to protect the Houseki Kingdom from everything that tries to take it over. The five warriors were blessed by the power of the Rainbow Jewels, the most powerful of the Houseki Kingdom. With the Rainbow Jewels, the warriors fought for the jewel land.

However, a few days ago, as the sorceress Agate turned against the Kingdom, the warriors suddenly disappeared. As it later turns out, the sorceress managed to defeat the Houseki warriors to get the power of the Rainbow Jewel and finally take over the Houseki Kingdom.
