ビッグコミックオリジナル
is a Japanese manga series written by Kazuya Kudo and illustrated by Naoki Urasawa. It was serialized in Shogakukan's magazine "Big Comic Original" from 1985 to 1988, with the individual chapters collected into eight "tankōbon" volumes. The series initially takes place in New York, but because its editor believed the magazine's demographic was men in their 40s, the setting changes to Europe at a certain point.
