One day, Kaoru and Sawako, a couple searching for their missing daughter, enter a deep forest where the "Legend of Kamikakushi" remains, clinging to any shred of hope. However, that place is not the "Forest of Kamikakushi," but a forest where Youkai, who lament the modern world that has lost the "heart to believe and fear" their existence, gather. Moreover, the day they entered the forest, "Doronpa," an annual prayer festival for Youkai to appear in the human world once again, was being held. Amidst the swirling intentions of humans and Youkai, Sawako is taken away. Will Kaoru be able to safely rescue his beloved Sawako and their daughter? Will the Youkai also be able to appear "Poof" in the modern world once again? Humans and Youkai, those who vanished and those left behind, oblivion and memory—all of them intersect. The festival-like Pandemonium of "Doronpa" begins!
