This Companion conjoins manga and anime as distinct while interrelated media forms. Focusing on corporate productions in the Japanese environment, it introduces how manga and anime operate individually and together. In line with this, common characteristics such as visuals, voices, serial narratives, and industrial conditions are addressed in a twofold way, that is, from the respective vantage points of both manga studies and anime studies. A form-conscious approach prevails, which results from the central position ceded to mature readers and viewers, acknowledging their imaginative as well as critical agency. This approach provides analytical tools that can be applied to changing contents and situations, up to and including non-Japanese productions and usages of the two media forms. Ultimately, the Companion offers insights not only into the media forms themselves but also into state-of-the-art manga studies and anime studies.
