Medoki is a vampire hunter affiliated with the Vampire Hunters' Guild, operating within the series' setting. He adopts a monk-themed aesthetic in his profession and holds additional employment as a store clerk at a shop specializing in vampire extermination goods. His primary professional partnership is with another hunter named Shōka. This partnership formed unconsciously due to Medoki's naturally helpful and caring disposition and the fact that both individuals share the same age. One noted personal preference attributed to Medoki is an attraction to women with small breasts.
