GurihiruGurihiru, also credited as Illustrator Unit Gurihiru and Gurihiru Studios, is a Japanese illustration team, consisting of Chifuyu Sasaki (workplan design, pencils, inks) and Naoko Kawano (workplan design, colors, webdesign). Both originating from Sapporo, Japan, they are currently based in Saitama, mainly working as artists for American comics.
The two women are art school graduates who worked as web designers and art museum receptionists prior to their work in comics. After entering a manga competition, they were advised to contact U.S. comics publishers, and they have since illustrated many American comics and graphic novels. Provided by Wikipedia
