Excel Saga(1996)

Excel Saga

Earnest young girls Excel and Hyatt (both codenames) hold down minimum-wage jobs to support their true avocation: trying to conquer the city of Fukuoka for the secret organization ACROSS and its dreamy dictator, Il Palazzo--a man whose dignity is such that he could never acknowledge that ACROSS consists of himself, a leaky basement, two unpaid teenage interns, and a stray dog. But society is all to blame, as creator Rikdo Koshi takes aim at everything from organized religion to public television, in a manga that makes reindeer spit blood and puts puppies on the dinner menu.
