Takaoka Shinnou Koukaiki

When he was young, Prince Takaoka had been told stories of India by Fujiwara no Yakushi, the favorite concubine of his father, as a bedtime story, and he had longed for that land. Decades later, as he grew up, he set out on an exotic, mysterious and fantastical journey to make his dream come true.
