Futari wa Pretty Cure Flash Fire

One of many OC fics for the Pretty Cure franchise that have sprung up around Livejournal, this one is written by flamingruby and features a "fire and ice" theme.

An extradimensional paradise known as the Crystal Plains housed numerous wonders. Among them was the music's ability to sometimes take on the form of a note-shaped gem if a song is important. A full set is required to complete the melody. Note gems that followed the order of the rainbow were said to be special, magical even. One paricular set, the Rainbow Notes of Life, protected this world and was guarded by twin pegasi: Hinote and his sister Kouri.

Beings from the Black Realm invaded the Plains; their leader, Lady Dischord led them in an attempt to steal and destroy the Rainbow Notes of Life, hoping to corrupt the Crystal Plains into a place filled with noise, evil, and despair. A desperate Hinote and Kouri took the Rainbow Notes of Life, carrying them to a place they hoped would be safe: the Green Plains, better known as Earth.

Of course, Lady Dischord isn't deterred, and she and her minions continue their search, hoping to corrupt both worlds. Unfortunately, she didn't count on Hinote and Kouri awakening the warriors Pretty Cure, Ember and Glacier, alias Homura Boukeno and Yuki Hanshou. Starting from Episode 9, the initial duo is joined by a Third Ranger in the form Homura's friend Aiden, who works in conjunction with the pegasus Eika.

Together, can they find the eight Rainbow Notes and unleash their song to save both the Crystal Plains and the Green Plains?

This fanfic contains examples of:
"Homura: (sighs) Please don't make me sing...
 * Development Hell - Due to a computer crash, this will be the case until further notice.
 * Elemental Powers
 * An Ice Person - Cure Glacier
 * Playing With Fire - Cure Ember
 * Eviler Than Thou - Several Black Realm minions, specifically Bruyant and Lautia.
 * Gilligan Cut - In episode 32.

[later]

Hikari: Okay, sing the doll's part for me.

Homura: (shakily and badly) Star light, star bright, first star I see tonight. I wish I may, I wish I might, have the wish, I wish tonight...

Hinote: (covers ears) Now I remember why you don't sing, hino."


 * Hoist By His Own Petard - Sure, Bruyant, go ahead and turn the entire Wi-Fi network into a Urusainaa! That can't possibly backfire!
 * Meaningful Name - Homura's name means "Flames of adventure" (as she lives for adventuring) and Yuki's name means "Midnight snow". The villains might also count: each of the minions' names means '"noise" in another language.
 * Monster of the Week - Urusainaa
 * Non Action Guy - Aiden, although not useless or cowardly by any stretch. He still plays a very useful support role for Pretty Cure.
 * Non Human Sidekick - The pegasi. Unlike many Precure mascots, they actually participate more directly in battle; Hinote and Kouri have more supportive abilities, while Eika's are offensive, since her partner cannot attack on his own.
 * Talking the Monster To Death - In Episode 21, Precure combats a negativity-spewing Urusainaa in this way.
 * Theme Tune Cameo - The melody of the Rainbow Notes of Life may sound...familiar, as will Hikari's song in Episode 23. Plus, Homura dances to Harry Belafonte in The Movie.
 * The Movie
 * Transformation Trinket - DS's, believe it or not.
 * Shout Out - The "spoony bard" joke in Episode 21, among others.
 * Tomboy and Girly Girl - Homura and Yuki, naturally.
 * Three D Movie - Word of God says there'll be a 2D and a 3D version of The Movie. And by 3D, it means that the author will mention the effects spilling out of the screen in the narration.
 * Vaporware - The latest episode.
