Associate Professor Akira Takatsuki's Conjecture, Vol. 6 (manga) — Mikage Sawamura

“Because we will return—to the world of everyday life.”  Professor Akira’s scary story party became a strange tale in its own right when a ghostly voice was caught on the recording equipment—now it falls to the professor and Fukumachi to resolve the mystery of “The Night of One Hundred Horrors!” And Fukumachi’s summer has more in store, because Akira promised to head to Nagano with him and research the Festival of the Dead that Fukumachi saw on that muggy summer night of his youth that changed his life—and his ears—forever!
