CLAMP
CLAMP began as eleven members from their manga club while High School in Kansai, and  they were seven when they decided to work making comics: Tamayo Akiyama, Mokona Apapa, Satsuki Igarashi, Mick Nekoi, Nanase Ohkawa, Nanao Sei and Leeza Sei. Tamayo Akiyama left near 1990, after her colaboration in Derayd and Cluster; since then she worked in this second title. Nanao & Leeza Sei have dissappeared of manga. The current four members are Nanase Ohkawa (05/02/1967) team leader, scriptwriter and sometimes works with the general design; Mokona Apapa (06/16/1968), which name is a nick, looks after the artistic side and drawing; Mick Nekoi (01/21/1969) is the artistic directress in charge and she works with layouts, ink, SDs, and all that is necessary; and Satsuki Igarashi (02/08/1969) looks after all Ohkawa doesn't do, and she's also the official cooker and heading agent.
The most famous members are Ohkawa and Apapa, but CLAMP say that they works like a whole, and they have similar ages, live in Tokyo and like videogames and eating. They love manga and their job; they are truthly work-addicted. That's the main reason why they still keep an amazing production rythm.
There isn't very much about them. They don't use to appear in Comikets or another cons nowadays, and they keep a little of mystery in all their private life things.
