In Archer
To sate his obsession with archery, a young boy named Myro headed into the forest east of his town and set up a mkeshift training area there. After a full year of training, he finally managed to hit the bullseye, prompting the appearance of a Wish Stone, which allows two of the user's wishes to come true and takes away something else. Myro wished to become an elf and an expert archer, and the Wish Stone duly made him so, as well as taking his masculinity so that he became a woman.
