After a 4th remake, this is probably the best I can do with this. Tamamo no mae from Succubus Academy (I believe that's the name of the game). Otherwise just Blue Tamamo.

I recommend putting Multiple tails as a negative or she tends to bring way too many tails to the party. If she starts misbehaving lowering her lora strength to 0.85 or 0.75 fixed it for me.

I'mma be honest this one was a struggle and I dread the flaws it might have.
