I think I have all of Key the Metal Idol related vocal CDs yet I didn't
have this version of "Key no Lullaby" sung by Mima Tokiko (Iwao Junko).
I wonder why it isn't on any of the other CDs. It's such a nice piece.
Second track is Key's monologue in which she describes "Key no Lullaby."
CD silkscreen as well as the disc 6 & 7 insert has an illustration of
grownup Tokiko (Key) in miko-san outfit. It's so beautiful that I
became stingy and won't be making the image available. I wonder if
it's on the artbook. I should look into buying one.
