Marco Diaz found himself in a rather precarious predicament. He had been kidnapped by a succubus that had initially mistaken him for a girl. The reason for this case of ‘Grand Theft Marco’ was because the saccubus had been desiring for a protege to teach and pass her knowledge onto.

She could have easily gotten another demon or other magical being, but due to an odd sense of humor, she found the idea of taking a fresh mortal and converting them to be a fun one.

Marco had managed to quickly tell her that he wasn’t a girl, but this had the opposite effect of making the succubus even more excited at the potential amusement.

Star, meanwhile, eventually discovered that Marco had gone missing, and thanks to a rather oddly congenial note left behind by the succubus, she soon discovered where Marco had been taken.

Though Star tried to get there on time, she was too late to prevent poor Marco from being converted into a – rather adorable – incubus.

Marco, as an incubus would find that his main source of nourishment consisted of energy, which was something that was in large abundance thanks to Star’s overabundance of it. He also, due to the succubus he was converted by, acquired a secondary source of nourishment that he got from consuming sweets and sugary foods. Marco definitely did not want to have to dwell on the idea of... other alternative methods.

Marco was easily capable of hiding his horns, wings, and tail, but sudden excitement and surprise could cause them to pop back into existence just as quickly. Hiding his skin tone and hair color, though? That was a bit more tricky.
