Rainbow Pearls
Only Tōkotsu and Kyūki were favored enough by their master that he bestowed the red and purple Pearls onto them for their own use. They later lost them when Moroha stole Tōkotsu's red Pearl once she found his headless body, and the purple one taken by Riku the Pirate once killing Kyūki with his blue earring's powers.

Konton had hid the blue Pearl in his second armor. The orange Pearl was in the possession of its last member, Tōtetsu.
