Puyo Puyo Vocal Tracks - Rulue
From the Puyo Puyo Vocal Tracks album. This is Rulue's song. A vocal arrangement of her theme from Puyo Puyo!! 15th.Anniversary, "Fighting Queen, Rulue!", As performed by her seiyuu Kanako Kondou.
....I wonder why they used her 15th anniversary theme? (Not saying I dislike this though! This one sounds awesome too!)
