Harukanaru Toki No Naka De Hachiyoushou 

Motomiya Akane is your average high school student, best friends with anti-social and fiery Morimura Tenma and her lower-classman, the childish, dependent Nagareyama Shinmon.

They are walking to school together one day when Akane hears an eerie voice in the wind, beckoning her to come … without warning, Akane and her classmates are transported into a far away time … right in the center of Heian-era (?) Japan!

Akane is deemed the Ryuujin no Miko, vessel of mysterious and miraculous powers. Together with eight skilled (and beautiful) warriors from around Kyou (the capital), they must save the land from the Oni clan.

Akane’s powers are led to believe that she could save the world … or if swayed to the wrong side, could destroy it. The leader of the Oni clan is doing everything in his power to persuade her to join his side, and somehow Akane finds herself strangely drawn to him. Meanwhile, the Hachiyou are trying to protect her from the Oni clan, and even herself. Will they succeed and save Kyou from imminent destruction in the hands of Akram and the Oni clan?
