Production
Tokyo Babylon is based on a one-shot that Clamp head writer Nanase Ohkawa wrote for a magazine that featured dōjinshi. After Clamp got to illustrate the cover of the same magazine, Wings, with Subaru and Hokuto, the magazine proposed Clamp turn it into a series for their special edition South. Initially, the series was going to be called "Tokyo" but Clamp wanted to change it to give a more modern tone with the inclusion of Babylon according to them; the series was titled Tokyo Babylon reflecting how the city of Babylon resembled Tokyo, according to Clamp. The one-shot's characters, most notably Seishiro, were changed slightly when the series began.[3]
Subaru and his twin sister Hokuto, and Seishiro, were conceived by the series' creator Ohkawa for a dōjinshi novel about an onmyōji who hunts elves. Only its beginning remains. The characters were drawn twice for covers, and when South asked Clamp to create a new series for them, these characters were used. Originally, the twins were conceived more as mascots, with Subaru being a penguin called Leone, named after the Subaru Leone car. Both Subaru and Hokuto were modified from the original art, whereas Seishiro was completely redesigned. Ohkawa remembers having trouble writing Subaru as she was not used to writing kind-hearted characters. Like Kero from their other manga Cardcaptor Sakura, the staff thought about drawing a pet, with Subaru and Hokuto originally being considered as one. Since Subaru and Hokuto were the protagonists, whenever the magazines required an image for Tokyo Babylon, both Subaru and Hokuto were used together.[4]
When Tokyo Babylon's serialization began, Clamp was also writing RG Veda for the monthly magazine Wings. While the authors found this complicated, the series' quarterly publication of sixty pages resulted in the authors making several changes. The length of each chapter led the authors to write a darker story rather than a soft one as originally planned. Based on their experience in Tokyo, Clamp incorporated dark social themes, making the series realistic despite its focus on occultism. This also gave each chapter its own theme. Ohkawa believes their young age when writing the manga also influenced most of the series' negative messages. Although when the series began, the ending was already planned, it was not until the Tokyo Tower chapter that Clamp set the general atmosphere, with the pilot being perceived as a comedy. The next chapter involving Subaru's past meeting with a man, later revealed to be Seishiro, then sets the stage for the series' future. Since his introduction, Seishiro was written with the idea of him having a different agenda in contrast to his actions and dialog with the other leads. Seishiro was the easiest cast member to write while Subaru was the most challenging based on his good nature. In retrospect, Ohkawa believes that while RG Veda was their first series, Tokyo Babylon was their most original first work as they did not use other people's materials for this manga and it was influenced by their way of living. Though a 1990s manga, the narrative was influenced by the 1980s.[3]
In creating the art, colored weft and light colors were used for the main illustrations. This proved to be difficult for the authors. Ohkawa believes the art was influenced by the years when the manga was published. This is reflected in how Clamp's artwork changed, particularly the clothing and, most notably, Hokuto's dresses.[3] Mokona's works have been drawn with increasingly thicker lines across the serialzation of the manga. The character's faces have much thicker lines in the third volume of Tokyo Babylon compared to when the story first got serialized in South. This was made because the story had a serious, heavy theme, fine lines simply cannot bring out enough power to convince readers of the gravitas, so we make thicker lines when it fits the work. Such work caused Mokona to rely more on her stamina to properly draw the series.[5]
