Taiga is your typical
tsundere. Though rather rough and blunt on the outside, she is quite sensitive and mild-mannered. Though she acts tough in front of those who are intimidated by her, she is easily tamed and put at bay by her crush, Yuusaku Kitamura. It's because of this that Taiga seems to be receptive to people who aren't intimidated by her imposing nature -- which explains her close relationship to Minori Kushieda.
Taiga doesn't sugar coat, as she is as blunt as she is direct to the point. She has no problem spitting out the faults of other people, but she is easily set afire when someone else insults her back.
Despite her size (at 143.6 cm / 4'8"), Taiga is quite athletic, but thwarted by the fact that she's a klutz. She tends to make the most mistakes when it has something to do with Yuusaku Kitamura. Contrary to the clumsiness, Taiga is good in a fight, and makes her presence even more imposing by brandishing a wooden sword.
Though Taiga doesn't show it, she has high regard for the people closest to her -- even to the point of fighting for them, if the case may be. She can be rather emotional when it comes to personal issues, but she brackets this out by not letting it affect other people.
Taiga has peculiar tastes, as she leans towards lolita-esque fashion styles. Besides this, she is also insecure in several ways, such as for her lack of a bust, as well as for the fact that she can't swim, among others.
Taiga's parents are currently divorced, which lead Taiga to seek independence by living alone in an apartment. Her allowance is still provided by her father,
Rikurou Aisaka, who appears every now and then to make her stay with him -- only to have him leave her for some obscure reason. Her mother is currently married to another man, to whom Taiga is not very keen on living with.
