She previously published a 51-page one-shot manga titled Fushigi Yūgi: Byakko Ibun (Fushigi Yugi: Curious Tales of the Byakko) in Monthly Flowers in February 2015.
The manga went on hiatus in August 2018 due to Watase’s poor physical condition, and it has remained on hiatus.
Watase serialized the original Fushigi Yûgi manga in Shogakukan’s Shōjo Comic (Sho-Comi) magazine from 1992 to 1996, and Shogakukan published 18 compiled book volumes.
The manga will be the last story in the Fushigi Yūgi’s “Four Gods” storyline.
