Negi's wife?

[† The Joker]

There is a continued debate about who Negi's wife will be in Mahou Sensei Negima! manga following the revaltion that Chao Lingshen was 'supposedly' Negi's decendant from the future, though whether or not this is true or not in unknown, especially after the 'Family Tree' she had was destroyed, and may have even been fake.

However, suppose Chao was indeed his decendant? Who do you think would be his future wife, and why?

For instance, I my case, I'd be tempted to say someone like Ku Fei, because Chao was also supposedly part Chinese, and she seemed to have a natural talent for Martial Arts.
