Sinister-looking service head of Secret Services and Concierge of Maison de Ayakashi, who also lives in the property. Contrary to his sinister appearance - marked by the fierce look, a bald head, scars on the face and the sunglasses - he seems to have a very sensitive personality. When people talk to him, he gets nervous or even red in the face, and when he is in the presence of others, he doesn't utter a single word, that's why no one has heard him speak. It appears that Nekozuki has a soft spot within his misleading, menacingly-looking shell. He's extremely shy, and probably has low self-esteem issues as he bangs his head in the walls in an attempt to hide his face. (Source: Inu x Boku SS Wikia)
