Lumina Flowlight

Lumina Flowlight (ルミナ・フロウライト) appears in Sonic Shuffle as the guardian of the Precioustone in Maginaryworld, along with the world's goddess, Illumina. She is a pink, fairy-like being who bears a heavy resemblance to NiGHTS and some resemblance to Cosmo. She is voiced by Elara Distler in English and Ikue Ōtani in Japanese.

History
At the beginning of the game, Lumina brings Sonic, Tails, Knuckles, Amy and (unknowingly) Eggman to to the Temple of Light in Maginaryworld in order to acquire their assistance in repairing the Precioustone, which was shattered by Void. Later, she and Void cancel each other out, following her revelation that Void is the nothingness in the imagination that allows people to dream. In actual fact, Lumina and Void are two halves of the whole that make up Illumina in the first place.

Trivia

 * Lumina bears a strong resemblance to NiGHTS, and they share many similarities.
 * When the date on the Dreamcast is set to December 24th (or when the Dreamcast's internal clock recognizes that day's arrival), NiGHTS replaces Lumina. Likewise, on April 1st, she is replaced by Reala.
