Mahoutsukai Precure! EP31 - Crystalized Feelings! The Rainbow-Colored Alexandrite!!

During the train ride back to the Non-Magic World, Labut separates the girls' carriage from the snail train, trapping them in the space between worlds. Proving resilient to all of the Cures' attacks, Labut unleashes his full power, spreading everyone across the empty space. As everyone drifts into despair, Mirai manages to find her wand, remembering all the friends she has made through her encounter with magic and managing to send her feelings to her friends. With their feelings combined, the Cures reunite and bring forth a new Linkle Stone, Alexandrite, which transforms them into the Witchy Precure PreCure Over the Rainbow. Combining all the Linkle Stones with the Rainbow Carriage, the Cures gain the power to kill Labut. As the Alexandrite splits into three and returns inside the girls' bodies, a group of mysterious spirits suddenly appear.
