This is an interesting chapter. So Noah can't improve because he's been using human-style swordmanship which is unsuitable for him. But this raises some questions:
Why Olivia didn't think about it?
Maybe Olivia's master already know beastman-style is unsuitable for human so she only teach human-style to Olivia?
Or maybe Olivia know beastman-style but never teach it to Noah in order for him to blend with humans?
I wonder if Mao rubs the corners of her mouth on Master when she wants headpats, since that's where her salivary glands are. Actually, I could totally see her smushing her face into her belongings as she hugs them to scent mark them.
