Kazue is the kind of person that believes that if you don't have anything nice to say, you don't say anything at all. In this case, she prefers not to say much of anything unless absolutely necessary; using hand gestures to try to get things across to another person.

Because of her feline side, she does tend to be curious about things, examining things and wondering how things work. Even when she gets tired, she may end up trying to cuddle up to someone to get comfortable, 'kneading' into them before falling asleep from the warmth they provide. Of course she enjoys cat nip, dangling things, but she finds it insulting when others treat her like an actual cat despite of having characteristics of such.

When she was a tiny one, she had several siblings that she grew up with in the 'litter', counting on them for comfort and relying on them for emotional support. Though, when they came to the adult age, it was time for them to move on and be independent; this made the girl become a recluse, keeping to herself while exploring all that the world had to offer to her.
