In anatomy it is known as Michaellis's rhombus, sacral triangle, or simply sacral hiatus, to the space where we used to carry a tail before evolving, and even the monkey (an animal more similar to the human) still has the tail in the sacral triangle, anatomically the tails are drawn in that place for historical reasons, find out please ^^

Hey, very nice. From a point of view anatomy: the tail "should" start between her butt cheeks just above her butt hole not at above her ass. :-) She "should" have a special panties so her tail come through it.
