Desperate for more material, the writers of "Excel Saga" take a page or two from Koshi Rikdou’s old "masked heroes" parody Daitenjin, and have our hapless heroes in the Safety Assurance Agency (Watanabe, Iwata, Sumiyoshi, Matsuya, and both Ropponmatsus) made into the Municipal Force Daitenjin, against their will no less. In order to get out of the rather uncomfortable jumpsuits, the team goes about finding and dealing with all the terrible crimes (or not-so-terrible ones) they can find.
