She views the daughter of Kohaku Souji as an abomination against the world and her existence serves as insulting evidence of a Youkai spreading her legs for a human. While she has the urge to crush the life out of her frail body as every Youkai should, doing so would very likely end her participation in the mission against Yousuke, which she is very enthusiastic about seeing through. Because of this, she will stay her hand for the time being and simply observe the girl; one doesn't get too many chances to observe Hanyou.
She hears that he's a strong and talented warrior, but he looks to be the same as every other human man, which scores him few points with her. His relationship with a Youkai, producing his Hanyou daughter, also makes him someone that she'd kill without hesitation if she wasn't determined to go through with the mission.
Being a Youkai makes him probably the most respectable person amongst the group (other than her), and his abandoning his pompous house makes him even more so. She hopes to fight him at some point because he'll be the first Youkai she's fought in a while, and the only high born one she's fought since leaving for the human world.
He's fun and entertaining, drinking and fighting in a weird way that livens it all up. His love of violence is something she respects and loves to see, and it seems like it'd be interesting to get him drunk. Due to his slit eyes, she is working under the assumption that he is a Youkai and therefore deserving of more respect than the humans, though she is a bit suspicious over why he'd be hiding his energy with kelp, but such a thing isn't exactly something she'd put passed someone from the House of the Sea.
Due to her own situation as a crossdressing warrior, Uchimori's appearance and shyness, as well as her use of the more feminine naginata, she'll be half-expecting this male warrior to turn out to be a woman, and will probably try to find out her gender. If she does discover her to be a woman, she'll hold a sort of respect for her for being a warrior even in a society that says she shouldn't, elevating her above other humans in a way. Her quietness could use some remedying, which calls for the liberal application of sake and pestering.
A big guy who likes to beat people with a stick over something brittle like a sword is always a good addition. She could do without his focus on precision, but humans get weak after a few decades of life and she doesn't really expect that much from them.
He seems to be just like every other moderately armed human she's encountered. He's kind of stoic, a bland warrior to watch, and someone who can be a fun little distraction when he's drunk. She won't have any more problem with him than she has with any other human, but she's not overly intrigued by him either.
He's supposedly a strong warrior, which makes him respectable in her eyes, but his overreliance on speed and stealth diminish this and make him just another person whose only chance is to avoid ever being hit by an oni, because they're too weak to sustain such damage. At least he's quiet about his skills, as plenty of humans love to boast about their strength while in the presence of something far stronger.
