Starting with Volume 3 each volume of the manga features a structural drawing of a body on the cover that is relevant to one of the stories within. The cover and backcover also features a depiction of all the company members. However, only Karatsu gets a mugshot on each cover while the other characters may appear in some other manner or are hinted at. Above this depiction they are only identified as "Staff A" through "Staff E" (with the felt puppet Kere Ellis being "Staff E") and a description of their skill underneath. In the Japanese edition, the volumes come with a dust jacket using a paper stock similar to brown wrapping paper. Dark Horse attempted to emulate this cover style by using a similar stock for the cover of the English edition. However, starting with volume 12 Dark Horse switched to a glossier paper stock for cost cutting reasons.
