Okay, I am absolutely convinced that Janelle Monae is a unicorn Otherkin. The absolute perfection of motion, the insistence on magic and fantastical realism in her videos, the themes... and then the limber shape of her. J'rai tend to be thin and feel extremely tall for a human (original species form averages 8 feet, or 2.4 meters, tall). Ju'rema tend to be solid/hefty and be both tall and large for a human (big-boned, large body/limb ratio, often over 6 feet). Both types, when comfortable with their bodies, have immense power in the use of the physical form.
And unicorns are definitively magical beings. Just watching her, watching the laws of physics seem to bend when she dances (nevermind the tricks of camera and editing!) suggests either perfect study or some sort of enhanced ability. Either way, the effect is hypnotically magical. Spirit confirmation is a bonus, but I hardly need it here.
Regardless of identity, she's worth a watch. Jaw-droppingly awesome.
