This is "Yami ni Somari Yami o Harau" (Stained by Darkness, Dispelling Darkness) by Yasuhiro Hayase. This is the first solo book by Yasuhiro Hayase, a member of the urban comedy duo Toshi Boys, whose YouTube channel boasts 310,000 subscribers. It chronicles strange incidents he investigated as a paranormal investigator. It's a collection of horror stories based on true events, making for a compelling read.
