Ookami Shounen wa Yoru ni Naku

Overview

Hotokeda and Makami work the night shift at a convenience store. The two have a lot of free time and have had casual conversations, but after a certain lie that Hotokeda told as a joke, he unexpectedly opens the door to a whole other world. It's a supernatural comedy about a wolf boy and a young man pretending to be a vampire. (Source: Natalie, translated)
