Yondemasu yo, Azazel-san.

Yondemasu yo, Azazel-san, written and illustrated by Yasuhisa Kubo, began its serialization in Kodansha's Evening magazine in 2005. The series emerged during a period where dark, absurdist humor and transgressive gag manga found a significant foothold in the seinen market. Kubo’s work centers on a detective agency that specializes in summoning demons, utilizing a grotesque and cynical aesthetic to subvert traditional supernatural tropes through biting social commentary and slapstick violence.

The character designs were crafted to contrast the mundane, often sleazy reality of the human protagonists with the bizarre, chaotic appearances of the summoned demons. This stylistic choice helped define the series' identity, balancing repulsive imagery with sharp, rapid-fire dialogue. Following its initial reception as a cult hit, the manga gained further prominence with the release of an anime adaptation by Production I.G, which solidified its reputation for pushing the boundaries of television censorship through its irreverent tone.
