Koto was first talked about here with her Pixiv Market release, Marchen, which featured all original illustrations. This time around, Koto has released Partita Vocaloid Fan Book, a full color collection of Vocaloid illustrations that includes tributes to many of the popular songs like Magnet and Eager Love Revenge along with the new design for Hatsune Miku Append.
Koto was a relatively new artist to me when I first decided to pick up Marchen Original Illustrations. My previous exposure to her art work was from the first Pixiv Girls Collection art book, where she had one piece showcased and the Pixiv 2009 Year Book with six of her illustrations . In fact, many of the illustrations in Marchen can be found on her Pixiv account and on her website, but as usual they look better in print ^^;
