Puyo Puyo Vocal Tracks - Sig's Theme
From the Puyo Puyo Vocal Tracks album. This is Sig's song. A vocal arrangement of his theme from Puyo Puyo!! 20th.Anniversary, "Rapid Carefree Advice", As performed by his seiyuu Yuriko Fuchizaki.
I think this may just be my favorite song from the album. Very interesting sounding. Quite different from the game version, but still very charming in its own way.
