S1·E24 A Mysterious Gem – Brilliance is Within You!

Zakuro takes Ichigo to the rehearsal of a jewelry company premiere where she befriends a clumsy crew member named Tsukiko. Tsukiko really wants Zakuro to wear a rainbow stone necklace for the show, but both the stage manager and Zakuro reject it for being too modest. Ryou, Keiichiro, and the aliens all believe the stone is made from mew aqua. During the show, Kish tries to steal the necklace. The Mew Mews fight for the stone but are having a hard time with the chimera anima Kish is using until they are helped by the Blue Knight. After the monster is defeated, they discover the stone is not mew aqua. Deciding it is not an ordinary stone, Zakuro arranges for Tsukiko herself to appear in the show wearing a simple white dress and the necklace, proving Tsukiko's claim that the stone can make any girl shine.
