The song "Lost Butterfly" just made me love her. At first I only noticed the nice melody, but after understanding the lyric I was moved
Even bought her CD "Water Forest" from CD Japan.
Similar with Sakamoto Maaya ---- Rurutia is not doing a lot in promotion or advertisement stuff. She just does her music, purely.
BTW, she writes all the lyrics and musics her self. The arrangement is done by her in cooperation with Satou Taka.
However, I bet not many people can get used to the way she sings lol
