Fushigi Yûgi: Byakko Senki

Fushigi Yûgi: Byakko Senki (Japanese: ふしぎ遊戯 白虎仙記) is a Japanese manga series written and illustrated by Yuu Watase. It began with a one-shot, Fushigi Yûgi: Byakko Ibun (ふしぎ遊戯 白虎異聞), published in Shogakukan's Monthly Flowers magazine in February 2015. The full series, Byakko Senki, launched in the same magazine in August 2017. The series was officially on hiatus since August 2018 after missing the June 2018 release, due to Watase's health issues, but has since resumed as of May 2024.

Byakko Senki is a prequel to Fushigi Yûgi, a sequel to Fushigi Yûgi: Genbu Kaiden, and the final installment in the Fushigi Yûgi "Four Gods" storyline. It tells the story of the Priestess of Byakko, Suzuno Ohsugi, in the land of Xi-Lang after she was transported into The Universe of the Four Gods. The Byakko Ibun one-shot, on the other hand, sets the mood for Byakko Senki by introducing one of its protagonists, a girl from Xi-Lang named Ning-Lan, and her companion Nirusha.

In Japan, Shogakukan published the series' first compiled volume in April 2018. In North America, Viz Media licensed the manga for an English-language release and published its first volume in August 2020.
