It does seem strange that Mitsuo claimed to be a character that I could not find an equivalent to in the "Mafia Roles" page. I don't know Nanako, he may not be Mafia, but that doesn't mean he's one of us. It reminds me of the character Wednesday in the Addams Family Movie when asked about her Halloween costume, "I'm a homicidal maniac, they look just like everyone else."
