Yuu Watase's 1992-1996 Fushigi Yugi shoujo told the story of a pair of modern midde-school girls summoned into the Universe of the Four Gods as the priestess of Suzuka and Seiryuu. A 2003-2013 prequel then told the story of a Taisho Era girl summoned as the priestss of Genbu. Now, its Byakko's turn, with the story of Takao Ōsugi, the daughter of a Universe of Four Gods translator.
A Byakko Ibun one-shot ran in the monthly shoujo magazine Flowers' February 2015 April issue. The ongoing Byakko Hen is now schedule for magazine's October issue (on slae August 28th), and a new visual offers an early look.
