As the girls discover the Rainbow Carriage has its own magical mysteries, they are asked by Jun and the others to help out with their self-research projects before vacation ends. Meanwhile, Labut is seen with two other dark spirits, Shakince and Benigio. Upon hearing everyone's goals for the future, Riko becomes concerned that she doesn't know what she wants to do herself, but gets some advice from Liz. Just then, Labut attacks again with an artist Don-Yokubal, noticing that Kotoha's power seems different from regular magic. Standing firm in their love of magic, the Cures gain some power from the Rainbow Carriage and defeat the Don-Yokubal. Afterwards, Mirai and the others return to the Non-Magic World to prepare for school.
