@少女椿 I do know her! I really enjoy her song 月夜に気をつけて! from her best of album I have. I need to download more albums. @RickBuch This is nice! A more underrated idol I really enjoy is Tomomi Nishimura.
I like this kind of "innocent cute girl", as you may already realize xD
Talking about underrated, ironically this was my first 80s idol song, back in 2015. This started all for me!!!
