Web-ban Working!! is a web comic written and illustrated by Takatsu Karino, which she published in irregular intervals on her personal website since 2002. It is the origins of the serialized version of Working!! in the Square Enix's Young Gangan manga.
The web comic's setting and characters are different from the later four-panel comic strip manga. While the restaurant in the web comic and manga are both called Wagnaria, they are different branch stores, so the world is the same. For example, Sakaki Kenichirou, the web comic's store manager, is an old friend of Shirafuji Kyouko and Adachi Masahiro from the web comic is a band mate of Satou Jun from the Young Gangan version. The author called the web comic version Neko-gumi (猫組 - Cat Group) and the serialized manga version Inu-gumi (犬組 - Dog Group).
