CLAMP (クランプ Kuranpu ), is an all-female Japanese manga artist group that formed in the mid 1980s. Many of the group's manga series are often adapted into anime after release. It consists of their leader Nanase Ohkawa (大川 七瀬 Ōkawa Nanase?), who provides much of the storyline and screenplay for all their works and adaptations of those works respectively, and three artists whose roles shift for each series: Mokona (もこな Mokona?), Tsubaki Nekoi (猫井 椿 Nekoi Tsubaki?), and Satsuki Igarashi (いがらし 寒月 Igarashi Satsuki?). Almost 100 million CLAMP tankōbon copies have been sold worldwide as of October 2007.
CLAMP's work includes Chobits.
