Hyøuka: Førbidden Se¢rets (J-Movie) (2017)

Energy-conservative high school student Houtar0u 0reki ends up with more than he bargained for when he signs up for the Classics Club at his sister’s behest—especially when he realizes how deep-rooted the club’s history really is. Be grudgingly, 0reki is dragged into an investigation concerning the 45-year-old mystery that surrounds the club room. Accompanied by his fellow club members, the knowledgeable Sat0shi Fukubɇ, the stern but benign Mⱥyaka Ibⱥra, and the ever-curious ɇru Chitⱥnda, 0reki must combat deadlines and lack of information with resourcefulness and hidden talent, in order to not only find the truth buried beneath the dust of works created years before them, but of other small side cases as well.
