Ore no ude no naka de, ochiro

One day, Maria from the orphanage finds and cares for a beautiful young man who has fallen down on the road. It was a demon of black magic with jet-black hair and scarlet eyes who asked Maria, who wished to save his life, "Would you like to help?" After that, while receiving courtesy from a prince like the bright sun, the dark nobleman forced him to do midara acts many times by contract. This is a paper book version of the previously distributed "Angel is a Contract Slave of Incubus" with a newly drawn page.
