There wasn't an opening on the last and first episodes, but I do believe that your use of the term "opening theme" was confusing, or C9 meant the part where the episode title was shown.

Anyway, if you mean the background music at the start of the episode, I believe that it is "She is still sleeping", the 11th piece in the 2nd volume of the original soundtrack.
