I disagree, his students have way more stock with him than Anya. Nodoka, Yue or Evangeline will win, with Nodoka the 1st place runner so far since she's gone to such lengths to let his ass know. Asuna loves him as a friend and child, Konoka and Setsuna like him but love each other more, and the other girls just like him.
The manga makes a point of letting you know that even though he's 10, he's quite precocious(for the most part). Highly intelligent, handsome, gentlemanly, can kick serious ass and is a shota to boot. No, his students won't let that slide, if I recall one of the chapters even has one of the girls talking about how they should catch and groom Negi asap because of his future potential as a husband.
