The official website for the "Jump Festa '18" event lists "Yuragi-sō no Yūna-san Production Committee" with Shueisha and manga creator Tadahiro Miura as copyright holders. The manga will have a stage presentation at the event, which will be held at the Makuhari Messe event hall in Chiba on December 16-17.
Of the works that will have stage presentations at the event, only Miura's manga doesn't yet have an anime adaptation or an announced anime adaptation.
Yuragi-sō no Yūna-san launched in Weekly Shonen Jump in February 2016. The "odd story between a physical ghost buster and his ghost roommate" centers on a young man who encounters the ghost of a young girl at a creepy hot spring guesthouse. Shueisha published the manga's eighth volume on Thursday.
Last year's Jump Festa event announced the anime adaptation of Tabata's Black Clover manga.
