Azusa Shiratori 白鳥あずさ
Azusa Shiratori (白鳥 あずさ) is the female half of "The Golden Pair of Kolhotz High School". She is well known for her obsession for collecting things that she regards as being cute and then giving them names, usually with a French origin. "Azusa" means "catalpa tree" while "Shiratori" means "white bird".
Azusa is very unintelligent (a "half-wit" in the words of Kuno) and strange even by the standards of the series. Shiratori is a kleptomaniac and feels the need to take random objects and people regardless of ownership. If Azusa is denied, she will throw a childish tantrum and resort to violence, until she either has the object returned or is shouted at to stop.
It is worthy of note that the "level" of Azusa's kleptomania varies between the manga and anime continuities, with her being only shown to have in her possession one object at a time in the manga (the only possible exception being her having "Françoise" and "Charlotte" at the same time, although Akane was technically in possession of "Charlotte" at the time). In contrast, the anime shows Azusa as having multiple objects in her possession at the same time, each with it's own name (Azusa will also greet each object individually in the morning and evening) all of which reside in her home.
An example of Azusa's childish intellect reaches bizarre proportions at time as random factors can make her believe almost anything regardless of whether or not it is logical. One of the most strange, noteworthy and best (and comical) examples is her coming to the conclusion that Tatewaki Kuno was a magical Tanuki after a statue fell on him. This childish intellect also rears its head in her fighting skills as well where she primarily exhibits unorthodox battle techniques. Still Azusa understands battle tactics and in a rare moment of cleverness correctly deduced that Ryoga was her Charlotte. Though this can be attributed with her childish intellect or simply a lucky guess as most (logical and sane people) would only assume that Ryoga was simply wearing a similar collar to the pig.
