The Night Beyond the Tricornered Window, Vol. 9

A cryptic message from fellow exorcist Erika Hiura arrives at Hiyakawa and Mikado’s office. The team works together to discover the true identity of the Professor, but Hiyakawa has other, less upstanding ideas. When Mikado points out the crudeness of it all, Hiyakawa pushes him away, right into a cursed pond!
