These new cast members join previously announced talent, with Mirai Tachibana voicing the protagonist Yuri and Wataru Katō as Kail Muršili. Hiroki Nanami is also on board to voice Yuri's classmate and boyfriend Satoshi Himuro, in addition to narrating the series. Nanami will also perform the opening theme song, "Akatsuki no Sora."

Viz Media has been releasing the manga in English since 2004, with a new omnibus re-release ongoing since October 2024. The story follows Yuri, a modern Japanese girl mysteriously transported to the ancient Middle East where she becomes entangled in the politics of the Hittite Empire.
