Kensuke Shibagaki is a thirty-four-year-old man who works as a professional comedian, performing as the funny man or boke in the manzai comedy duo known as Homosapiens, where his partner is Atsuya Baba. Shibagaki is characterized by his strong ambition to achieve mainstream success and recognition in the comedy world, a drive that often puts him at odds with his partner, whom he views as a novice. His personality tends to be preachy, and his frustration with Baba's perceived lack of experience or skill leads to frequent clashes within the partnership. Within the story, his role is primarily that of a struggling entertainer whose professional and interpersonal conflicts are part of the larger narrative web. His key relationship is with his comedy partner, Baba, with their tense dynamic forming the core of his interactions. A significant aspect of his background, revealed in the narrative, is that he is actually a human being; the perception of him as an animal character is a result of the protagonist Odokawa’s condition of visual agnosia, which causes him to see people as animals.
