This is a CD that comes with the limited edition of Sola Color III DVD.
I couldn't find track information anywhere, other than the song, so I made up the rest.
Kaneda-san actually stays relatively coherent! That's amazing! I've listened to many radio shows in which she was the personality (or just a guest), and she tends to become all incoherent under self amusement. In this, she manages to clearly talk about childhood friends (Mayuko & Takeshi), memorable items (Rabbit plush), etc.
Song is a bit boring (combination of music and her singing), but it's not annoying.
Drama supplements the anime episodes on the DVD. Make sure to watch the DVD first.
