Cheer Up Time is a bonus installment of the Assassination Classroom television anime, standing as the second of the show's special episodes. It sits between the nineteenth and twentieth entries of the second season and draws its material from the original manga.
Cheer Up Time is counted apart from the numbered broadcast run, serving instead as an extra addition to the Assassination Classroom anime. It ranks as the second special produced for the series, wedged in as a half-step between the nineteenth and twentieth installments of the second season. Rather than advancing the main sequence, the piece reworks scenes lifted straight from the source comic.
Within the viewing order, this bonus entry falls between Episode 41 and Episode 42. It keeps the musical framing used across the rest of the second season, leading with the theme Bye Bye YESTERDAY and closing on Mata Kimi ni Aeru Hi.
