Doujinshi

From Media Technology and Culture Change

Doujinshi is an artistic movement in Japan parallel to manga. It consists of copying a comic and altering it whether slightly or significantly. There are no limits to what can be altered in a doujinshi comic. The artist may chose to change the story-line, a character, several characters, etc. Although it can be seen as a form of piracy, it is widely accepted in Japanese culture.
