A manga adaptation by Yū Satō will launch on Drecom's Drecomi+ manga website in September. Drecom will publish the third novel volume on July 10. A promotional webtoon adaptation was produced by MITA, Gudan, and Red Seven.
The announcement comes from a press release distributed on Friday. Author Damu Amato said in a statement, "It's getting an anime!? I can hardly believe it myself, but a dream I've been imagining since childhood, a big, big dream, has become reality." Director Chihiro Kumano called the series "a work with a rare and dreamlike charm" and said he hopes to portray "both the beauty and the cruelty of this world as a hymn to all of creation." Original character designer Shirabii also shared congratulations, saying they look forward to seeing the cast come to life in animation.
Kumano previously directed the Odekake Kozame second season and its film, and worked as an episode director on Unnamed Memory. Series scriptwriter Satoru Sugizawa's credits include Ameku M.D.: Doctor Detective, Love After World Domination, and Why Does Nobody Remember Me in This World?. Character designer Akane Kasasagi was a sub-character designer for The Invisible Man and His Soon-to-Be Wife and Once Upon a Witch's Death.
The story follows Leen, a descendant of the legendary witch Ringleen who can command monsters. After she saves adventurer Hakura from a hydra, the two travel together in a world where humans and monsters coexist, taking on cases involving creatures that are rarely as simple as they appear. The English translation by J-Novel Club describes them as "arguing and bickering every step of the way."
