In terms of the Isekai genre, one of its initial representations was “Warrior From Another World” by Haruka Takachiho, debuting as a manga back in 1979. Since then, this fantasy genre has been evolving and gaining traction, even branching out in unanticipated directions lately. Although “The Twelve Kingdoms” might not receive as much recognition as other Isekai series, it’s still making a splash with its upcoming live-action stage play. The series first emerged through Kodansha publishing in 1992 and has continued to produce new chapters due to creators Fuyumi Ono and Akihiro Yamada. Similar to many manga, the series was adapted into an anime in the early 2000s and is now available for streaming on Crunchyroll.
