From what I've read on the manga, she's like more or less louise, maybe less.She had to make it sound a little different than Shana/Nagi/Louise, plus, Taiga is much more mean than those three She gets better later on though!

But who knows, maybe the novel had different theme. I loved the introduction scene though, nothing start a fairytale romance better than an uppercut.
