Harukanaru Toki no Naka de (遙かなる時空の中で, lit. "Within the Expanse of a Distant Time") is an otome adventure game developed by Ruby Party and published by Koei. It is a part of Ruby Party's Neoromance label. Because of Harukanaru Toki no Naka de's success, the game has given rise to a franchise including several sequels, numerous drama and music CDs, a manga series, two OAVs, a movie, and an anime television series, and a live-action theatrical. On the first day of a new school term, high school student Akane Motomiya, her classmate Tenma Morimura, and their underclass friend Shimon Nagareyama are sucked into a mysterious old well. When they awake, they are in Kyō (京), another world that resembles Kyoto during the Heian Period. According to the young scion of the Star Clan (星の一族), Fujihime, Akane is the Ryūjin no Miko (龍神の神子, Priestess of the Dragon God) who has come to save Kyō from the ambitions of the Oni Clan (鬼の一族). In this task, Akane has the help of eight beautiful and single men known as the Hachiyō (八葉), and her friends Tenma and Shimon number among them. Initially, Akane is bewildered by her new circumstances, but she gradually comes to face up to her own destiny and understand the world of Kyō.
