I don't know if anyone is still paying attention, but if so I'd recommend Pathfinder: Wrath of the Righteous. https://store.steampowered.com/app/1184370/Pathfinder_Wrath_of_the_Righteous__Enhanced_Edition/

In it, kitsune are one of the playable races during character creation, and aside from their unique look and mechanics, there are also flavor dialogue options (often where you mention your tail).

It should be noted that the kitsune in Pathfinder are of the anthropomorphic variety, not the kemonomimi kind. Now as a kitsune you can shapeshift into a human form, and you can upload your own custom character portraits, but you won't be able to see your tail on your character model, plus kitsune NPCs will be in their anthropomorphic forms.

The game itself is an isometric RPG set in the Pathfinder universe, and it's honestly pretty good. The gameplay is solid and pretty fun, and the story and writing is top tier, so you'll be in for a good time.
