Magical Rainbow Pretty Cure (マギカル レインボー プリキュア Magikaru Reinbō Purikyua) is the first Pretty Cure series created by Crazyanimefangirl,
who is rather inexperienced in making articles.
Ayaka Momoyama is a 13 year old girl who meets a dog-like fairy named Hue when she is walking home from school. Hue tells her that he is from the Colour Kingdom and it is in danger because of another kingdom, the Colourless Kingdom. Suddenly, a man who introduces himself as Nibui appears in front of them. He turns around and throws something that looks like a ball of black ink at an upset man passing by. The ball sucks his colours from him and as the man collapses, the ball becomes a monster known as a Kurokaiju. Ayaka backs away slowly, shocked, but then Nibui notices Hue and says he is going to capture him. Ayaka tries to protect Hue. Then a colourless rainbow appears in the sky and one of the parts turn pink. Hue realises Ayaka is the one to become Pretty Cure and gives her the Rainbow Phone and Colour Charm. She is told to say “Magical Rainbow Change!”. Now Ayaka is Cure Carnation! But she has to defeat the Kurokaiju.

The collectibles. The charms are shaped like hearts. The colour of the heart in the middle is white while the heart around it depends on the cure’s theme colour. Cure Colourful’s charm has no white heart in the middle and has the theme colours of the other 7 cures on it due to her being a special cure.

- There was actually going to be an indigo cure named "Aizawa Rena", but Crazyanimefangirl decided not to make her due to the lack of colours while making the characters' pictures and it would save her a lot of work, too.
