I know that if I had a wish, then I would have wished that I would have never stumbled upon today's offering, an obscure little title from the Go!Comi library.
KING OF THE LAMP (Lamp no Ou-sama), by Takako Shigematsu. First published in 2004 and first published in North America in 2007.
PLOT:
Long ago, a raunchy king stole 1000 women to fill out his harem. As punishment for his crimes, he was turned into a genie who must fulfill the wishes of 1000 women before he can be freed. Thus, we watch him work his magic with a shy girl who wants her sempai to notice her, an older sister crushing on her baby brother's kindergarten teacher, and an awkward girl in love with her older sister's blind boyfriend. Also included are stories about a young woman with a pair of mysterious guardians and a medium and their guardian spirit trying to shake off an otaku with an eye for the supernatural.
