I swear Kumin's VA's normal singing voice sounds exactly like Rikka's anime voice. I didn't even realize the first line of sparkling day dream (shibaraku...) was sung by Kumin's VA until I checked it out.
I also like it Also I will reupload all the songs with credits and better quality for some These uploads are before I got lossless copies of all the songs. I also have to remaster them because the CDs have terrible mastering
