^As far as I know, Maaya has been more active in the anime/dubbing world. Apparently she released Follow Me Up in 2015 so it's been nearly 3 years.
You're welcome for the track! I couldn't find the Doriuta album anywhere online and I'm such an obsessive Maaya collector that I needed to hear it however possible lol. It took me about 6 years to finally get my hands on the "yoake no kaze kikinagara" single as it's only available in 8cm single (those 90s style long cases with the tiny CDs) that I ended up buying it in a bundle with 4 other singles that I already had. So I have double copies of Kiseki no Umi, Yubiwa. Shippo no Uta and Yakusoku wa Iranai.
EDIT: The Risky Safety ending, yoake no kaze kikinagara", for reference.
