Chobits
"Chobits" began as a manga written and illustrated by Clamp, a collective of four Japanese manga artists. It appeared as a serial in "Weekly Young Magazine" from the 43rd issue for 2000 to the 48th issue for 2002. Kodansha compiled the eighty-eight chapters into eight bound volumes and published them from February 14, 2001, to November 29, 2002.
In 2002, Tokyopop licensed "Chobits" for an English-language translation in North America and marketed it as part of its new unflipped manga line, which reads from right-to-left. Previously, translated manga was typically flipped from its original reading order to a left-to-right one to better suit Western readers. Tokyopop published the series from April 23, 2002, to October 7, 2003, and its translation was distributed in Australia and New Zealand by Madman Entertainment. Tokyopop's license concluded in 2009. At San Diego Comic-Con International 2009, Dark Horse Manga announced an omnibus edition of the series in celebration of Clamp's 20th anniversary. In 2010, it published the two volumes on March 24, and September 29, respectively.
"Chobits" is also published in Hong Kong in Traditional Chinese by Jonesky, in Singapore in Simplified Chinese by Chuang Yi, in South Korea by Daiwon C.I., in France by Pika Édition, in Spain by Norma Editorial, in Mexico by Grupo Editorial Vid, in Italy by Star Comics (which serialized it in "Express"), in Germany by Egmont Manga & Anime (which serialized it in "Manga Power"), in Poland by Japonica Polonica Fantastica, in Brazil by JBC, and in Sweden by Carlsen Verlag.
Magic Knight Rayearth
A friend of Clamp, illustrator Takeshi Okazaki, created the "Rayearth" part of the title, while Ohkawa thought of the rest. At that point, Clamp had completed a "basic" idea of the plot. For the names of the characters, they drew on car names, feeling that they would be interesting and memorable for children, who might otherwise have difficulty learning the names of characters in katakana. The inclusion of giant robots gave the artists some difficulty, as the massive scale of the robots made it impossible to depict the characters and robots in the same frame. The artists also omitted the cockpit of the robots, to show their faces instead. Greatly anticipating the ending to the first part of the series, Clamp found the protagonists' initial adventures in Cephiro "really easy" to create. Ohkawa noted that, had their target audience been older or male, they would have considered stopping the series with the conclusion of part one. The second part, however, proved difficult for the group to create, as they felt as if they had "written [them]selves into a corner".
