when i created the Nyxad or Night Nymph. i reskinned the Half Drow but gave them the option of choosing to have the drow darkvision/light sensitivity package instead of the elven darkvision package. chosen at char gen. 

you could Arguably Reskin a Similar Race for a Nekomata or Kitsune, though i'd imagine half elf is a Flexible starting point for either. i swear, for most kemonomimi and most cutesy seelie or unseelie fey, i recommend reskinning the half elf of some flavor and representing your youkai type through your racial skill choices, class and background choices and feat choice.

though i swear Half Elves are the new "reskin this race for a cutesy Anime Girl" Race based on what i have seen and it saves a lot of time spent homebrewing.
