This is not a Tsukasa This is a parody of La Trahison des Images (The Treachery of Images) by René Magritte which has a picture of a pipe and reads "ceci n'est pas une pipe" or "This is not a pipe." The point is it ISN'T a pipe. It's an IMAGE of a pipe. The fact that Tsukasa herself is a fictional character makes any actual meaning behind this other than humor an exercise in existentialism.
