Inspired by the manga novels, Warrior Nun hails from creator/executive producer Simon Barry, who also serves as showrunner. It revolves around a 19-year-old woman (Alba Baptista) who wakes up in a morgue with a new lease on life and a divine artifact embedded in her back. She discovers she now is part of an ancient order that has been tasked with fighting demons on Earth, and powerful forces representing both heaven and hell want to find and control her.
Rayann will play Yasmine Amunet. Yasmine is a Coptic Nun who is also a scholar and freelance journalist. Yasmine is an intellectual, not a fighter, who finds herself drawn into Warrior Nun Ava’s journey.
