I have no idea what she’s saying but Ichiko Aoba with her heavenly voice seranades me to sleep every night. Check her out, you won’t regret it.
I decided to run the lyrics through Google Translate
[Ichiko Aoba “Fuwa Rin” Lyrics]
Softly, softly, look up at the sky
Soft, soft, afusing clouds
Wander alone
I’ll tell you my secret.
If you get off the station from there,
You can hear the sound of the key.
I’ll tell you your secret.
Under the mask is a horrible face
Show it to everyone.
Soft, soft, invited to a comfortable sleep
Softly, softly, collect feathers
Wandering through the dream.
