His design is taken from the /cm/ board of 4chan's genderswapped/trap version of the "Ecstasy AKA Darks" meme. Said meme originated from 4chan's /a/ board back in 2007. The original image of Darks was an image of someone's self-insert original character posted on DeviantArt, said image depicted a poorly-drawn generic emo boy with blue-dyed black hair and a small list of his likes (Blood, Death, Knives, Psycos, Pointy objects, Green Day, and staying up all night), dislikes (Peace and love), age (13), and height (5"2).
Sometime in 2010, someone took /cm/'s super kawaii version of Darks and turned him into a Vocaloid trap. He retained most of his characteristics but was given a different name so that trolls wouldn't find him. He dresses up as a girl, does covers of songs using his own UTAU sound bank, and has buttsex with other fan-made UTAUs for the amusement of young yaoi fangirls on DeviantArt.
This page and tag on danbooru is for the created UTAU.
