Carmen Campuzano was born on December 7, 1970.
So far, there seems to be no indication of this happening, since she has returned to her own time, in the future. However, since the manga is still ongoing, it is still possible for her to make an appearance, although highly unlikely. There was however that promise between her and Negi that they would meet each other again in the future. Whether this is because Negi might possibly find a way to get to the future or he actually manages to live that long is unknown though, or if Chao decides to return to Negi's timeline is also unsure. Edit: Chao did return at the end of chapter 352 when Asuna was sealed off for more than 130 years. In this future, everyone has passed away including Negi and the only ones who were still alive were Evangeline and Chao. This Chao is the same one who went back in time and she has developed a machine that lets a person travel between parallel worlds. Asuna was so distraught over the fact that her friends are all dead, Chao and Eva decided to send her back by using the new time machine Chao has created thus Asuna was able to reunite with all her friends again.
