She's not a futa lmao. This is taken straight from the wiki:
Luna Luna has a colorful bluish-white wing on the right of her head, and a purple horn on the left. She wears a very revealing outfit, consisting of white cloths with blue ends attached to her upper arms, and ornate strings that go down her torso and ***attach to a purple horn-like piece, with white pearls going underneath her.*** On her legs she has detailed thighbands and fishnets leading down to her detailed sandals. One of her most notable features is her four multi-colored tentacles. She can also alter the pigmentation of her skin.
