The Twelve Kingdoms: Shadow of the Moon

Empress returned from Yamato. The Royal En, King Shouryuu, having answered her Petition, the Empress quelled the Rebellion at the Close of the Seventh Month, and deposed the Pretender, Joei.
    In the Eighth Month of that Year, the Empress Youko ascended Mount Hou and there accomplished her Investiture. Her Name was recorded upon the Census of Heaven, and she was granted the Title of Royal Kei. The Royal Kei re-interred the Late Empress Yo at Gyouten, appointed six new Ministers of State, and established the Government.
    The Era of her Reign was designated Sekiraku , from the First Character of the Imperial Insignia and the Name of her Friend and Confidant, Rakushun. And so was inaugurated the Imperial Court of the Red Child.
