While Japan does have a thriving independent comic market for amateur and semi-professional artists, creating manga professionally is rarely a solo effort.[citation needed] Manga artists must work with an assortment of others to get their work completed, published, and into the hands of readers.
Editor
Most professionally published manga artists work with an editor, who is considered the boss of the manga artist and supervises series production. The editor gives advice on the layout and art of the manga, vets the story direction and pace, ensures that deadlines are met, and generally makes sure that the manga stays up to company standards. Naoki Urasawa compared the relationship between a manga artist and their editor to that of the one between a music producer and a recording artist, specifically citing George Martin's relationship with The Beatles.[8] The editor may also function as a brand manager and publicist for a series. When a manga is the basis for a media franchise, the editor may also supervise the designs for anime adaptations, and similar products, though this duty may also fall to the manga artist or an agent.[citation needed] An example of a manga artist and their editor is Akira Toriyama and Kazuhiko Torishima.[9]
Assistants
Most manga artists have assistants who help them complete their work in a clean and timely manner. The duties of assistants vary widely, as the term incorporates all people working for a manga artist's art studio, but is most commonly used to refer to secondary artists. The number of assistant artists also varies widely between manga artists, but is typically at least three. Other manga artists instead form work groups known as "circles" but do not use additional assistants, such as the creative team CLAMP. A few manga artists have no assistants at all, and prefer to do everything themselves, but this is considered exceptional.[citation needed]
Assistants are commonly used for inking, lettering, and shading, though the predominance of black and white art in manga means that unlike in the western comic industry, a studio rarely employs a colorist. Some manga artists only do the sketchwork for their art, and have their numerous assistants fill in all of the details, but it is more common for assistants to deal with background and cameo art, leaving the manga artist to focus on drawing and inking the characters. Assistants may also be employed to perform specialized artistic tasks. Go Nagai, for instance, at one time employed a specialist to draw helicopters and other military vehicles,[3] Kaoru Mori employed a historical consultant for Emma, and series that incorporates photorealistic architecture, animals, computer-rendered imagery, or other technically demanding effects may employ or contract separate artists trained in those techniques. Assistants almost never help the manga artist with the plot of their manga, beyond being a sounding board for ideas. A manga artist's assistants might be listed in the credits for a manga tankōbon, and short interviews with or illustrations by assistant artists are a common form of bonus material in these collections, but they typically do not receive individual credits.[10]
Most manga artists started out as assistants, such as Miwa Ueda to Naoko Takeuchi, Leiji Matsumoto to Osamu Tezuka, Kaoru Shintani to Leiji Matsumoto, and Eiichiro Oda, Hiroyuki Takei and Mikio Itō to Nobuhiro Watsuki, who was himself an assistant to Takeshi Obata. It is also possible for an assistant to have an entire career as such without becoming an independent manga artist. Assistants, particularly specialists, may work with several different manga artists at the same time, and many assistants also self-publish works of their own in the dōjinshi scene.[citation needed]
