I think that's done on purpose. She has a very masculine personality, and I don't say that because she's strong or a fighter, she just does have a more proactive, straight to the point, dominant atittude. She's also supposed to be someone whose emotions you wouldn't be able to read easily, it's something she had to leaern to protect herself,
I'll be honest... I really want Kyuu's fur pattern to have a different design/style. Instead of a hatching style, maybe a solid black instead? And just use white pen or negative space (if it's possible) to draw the details (a.k.a nose and mouth). It's just that it looks like she has a beard and it's really hard to see/read her expression, like if she was blushing or not. Key examples: if she was flushed from excitement after meeting Louis again, or finding out about Gouhin-san.
