A small grin on her lips even she would find the woman rather adorable
"Well perhaps not now, but you have a long life ahead of you, and you and I both know I am not going anywhere"
Ears wiggling in response to Scathach's headpats, as Ayumi would lean in a little bit closer.
"Hehe, I'm happy you think so highly of me. But I'm sure I wouldn't be able to be a match for you."
Scratching the back of her head.
"You have the heart and mind of a strong warrior Ayumi I am pleased with your progress"
Softly patting her head rubbing her ears for a time before speaking again
"Who knows perhaps you might be the one to end me, one day"
"O-Of course! Aside from my magecraft I've been also keeping up with my sword training."
Proudly puffing out her chest, of course she knows she's no match for the Queen of Shadows herself.
. . .put she's still happy about her progress.
