Hmm...
Yuri Kasahara is credited as vocalist in the notes field, which conforms with the information from the booklet (page 3).
However she isn't mentioned in the artist infomations. At least not as performer, but she IS mentioned as lyricist. Now the notes field says that Chiaki Ishikawa is the lyricist. But that information doesn't seem to come from the booklet, or I'm just blind
Any ideas?
