Asuna Kagurazaka

As one of the main characters of the series, Asuna has been known to have quite a short temper and frequently her actions are a bit rash, but at the same time, has some aspects that display her maturity, especially when it comes to doing the right thing. Although at first she really detests Negi, over time she becomes like a big sister role model to him, as she does resemble Negi's cousin, Nekane, in a way.
