The Moon-Painting Alchemist

By the king's order, Ennid, a genius alchemist, needs to develop a potion that shows one's future companion. While experimenting, he sees a man in the mirror and then a boy.... The test has failed, or so he thinks. But, soon, he meets the boy and saves him from slave dealers. Later, the man in the mirror appears in place of the boy and defeats assassins who follow the boy. Ennid can't take his eyes off the man named Glunn, who is wearing no clothes. "Wait a minute, is that huge thing between his legs...?!" Can Ennid break the curse of Glunn, who may be his future companion?+
