So the second character song CD focuses on Sachi and Silica. Definitely a contrast between the two songs.
Sachi's "Memory Heart Message " was really nice. Just liked the music and was nicely sung. Not overly sad as you might think, but somehow I just feel like the title fits nicely with this. Makes you think back to the tragedy of her loss. On that note wouldn't have been against including a track of her singing "Rudolf the Red-Nosed Reindeer"
.
Silica's "Lovely Super Idol" really does fit the title
. Have to give a nod to Sachi's song in comparison, though this one certainly has a lot of energy. If you are in the mood for some fast paced music then this will work out fine.
