Actually, the singer is a human girl who goes by the name ‘nagi’
yep and she has a beautiful voice. xD
Are you sure both covers are done by redjuice? The one on the right looks more like Miwa Shirow’s (another member from Supercell) work. The left is definately Redjuice though… maybe he changed his style a bit for the right one if he did do it? ^^;
Kidoru, you’re right the cover was designed by Miwa Shirow:
