series Cardcaptor Sakura, the group successfully pitched Chobits to the Japanese manga magazine Weekly Young Magazine. Clamp completed fourteen pages per week for Chobitss weekly serialization, totaling fifty-six pages a month. The title of the manga has its origins in "Chobi", the name of a cat at the place of Nekoi's former employment, which the group made into "Chobits", as the characters Elda and Freya were twins. Ohkawa designed Hideki and Chi first. Chi's design as a personal computer resulted from Ohkawa's wish to increase the sense of "emotional discomfort" around becoming emotionally involved with something considered to be merely a lifeless machine. The characterization of the protagonist Hideki proved to be difficult for her; in the beginning, she considered an "aloof" man who gradually warms up emotionally or a sex-obsessed man. She decided that neither characterization would be a good fit for Chi and settled on one of a penniless and benevolent student. In keeping with the conventions of the romantic comedy genre, the group had planned to introduce conventional characters, such as an older female neighbor and a physically attractive friend from childhood; in the case of Chobits, the "childhood friend" never appeared. The artwork was done in ballpoint pen to evoke the sense of "rough" lines, and colored pages were done in acrylic gouache. Media Manga Chobits began as a manga written and illustrated by Clamp, a collective of four Japanese manga artists. It appeared as a serial in the seinen manga magazine 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 10th anniversary. In 2010, it published the two volumes on March 24, and September 29, respectively. After Dark Horse Comics' license expired,
