Gurihiru, also credited as Illustrator Unit Gurihiru and Gurihiru Studios, is a Japanese illustration team, consisting of Sasaki (workplan design, pencils, inks) and Kawano (workplan design, colors, webdesign). They are based in the city of Saitama, Japan.
The two women are art school graduates who worked as a web designer and an art museum receptionist 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.
