Libre Publishing's Kurofune label has announced on their official Twitter account that Tomoko Yamashita's The Night Beyond the Tricornered Window manga is getting a TV anime adaptation. No additional details have been announced at this time.
The manga is also inspiring a live-action film adaptation that will premiere on January 22, 2021.
SuBLime is releasing the manga digitally, and it describes the story:
Shy bookstore clerk Kosuke Mikado has the ability to see ghosts and spirits, an ability he wishes he didn't have, since what he sees usually terrifies him. Rihito Hiyakawa, an exorcist whose supernatural powers are as strong as his social graces are weak, doesn't seem to fear anything, mortal or otherwise. When this odd couple gets together to solve the bizarre cases that come their way, their work methods may not be entirely safe for work!
