In 2004, Clamp's 15th anniversary as a manga artist group, the members changed their names from Nanase Ohkawa, Mokona Apapa, Mick Nekoi, and Satsuki Igarashi to Ageha Ohkawa, Mokona, Tsubaki Nekoi and Satsuki Igarashi (her name is pronounced the same, but written with different characters) respectively. To celebrate Clamp's 15th anniversary, Tokyopop released a twelve-part magazine series entitled "Clamp no Kiseki" that contained a plethora of information for fans. The August 2004 issue of "Newtype USA", a magazine specializing in events of the anime and manga subcultures, reported that the members of Clamp simply wanted to try out new names. In a later interview with Ohkawa, it was revealed that initially Mokona wanted to drop her surname because it sounded too immature for her liking, while Nekoi disliked people mistakenly commenting on her as a Rolling Stones member. Ohkawa and Igarashi, wanting to go with the flow of Nekoi's and Mokona's name changes, changed their names as well.
