This one features Megurine Luka, the third Vocaloid. Unlike the earlier mascots, her costume's not based on a school uniform. You'll see some instruments on her, like woodwind and brass.
This is actually a fan artbook so you'll see how fans redesigned her. The overall style is Japanese-like and you'll see shades of pink that are taken from her long hair. The illustrations are beautiful and well done.
