This CD is a little old, but I just found it at the used stores.
(I needed the DVD.)

Kaze wo Atsumete
Breave My Heart
LASM-34030
released 2009.11.25
1890 yen

This CD+DVD package contains the Ragnarok Online 7th Anniversary Songs.
This is Sphere's third single.

The tracks are as follows.

   1. Kaze wo Atsumete (風をあつめて)
   2. Brave my heart
   3. Kaze wo Atsumete (off vocal)
   4. Brave my heart (off vocal) 

Songs by the seiyuu group Sphere, made up of Kotobuki Minako,
Takagaki Ayahi, Tomatsu Haruka, and Toyosaki Aki.

The DVD contains a promo video of "Kaze wo Atsumete", which is in
wide format (16:9).

This is Sphere's best promo video so far, with many closeups of the
girls, wearing "normal" clothes (non-stage outfits). They don't wear
the jacket photo outfits in the video. 
Toyosaki Aki is VERY CUTE in this video.
