Ansatsu Kyoushitsu 2: Kagaijugyou-hen is a set of eight ONA shorts released in 2016 as a companion to the second TV season of Assassination Classroom. The shorts bring to the screen two manga chapters from the ninth volume that the television broadcast left out: chapter 78, "Takebayashi no Jikan," and chapter 79, "Shihaisha no Jikan, Ni Jikanme." Like the main series, they mix action, comedy and supernatural elements.
