Rainbow has announced that they'll be starting unit promotions as a trio with 'Rainbow Pixie'! On January 3rd, DSP Media updated their official homepage with teaser showing the silhouettes of three members. They also kicked off an event where fans can guess who the three members are for the 24 hours until the trio's full reveal. As Rainbow is known for their mature, sexy concepts, the trio will be playing to the group's cuter side, just like the meaning of their name 'Pixie'. Their title track, "Hoi Hoi", is about a spell cast by elves and is described to have a friendly melody that will be easy for anyone to follow. The event ends on January 4th, and fans can expect to see the members, jacket photos, and music video teasers until the album's full release on January 12th. Who are some of your guesses?
