According to the latest issue of Shounen Jump, manga "Ansatsu Kyoushitsu
" will have a special anime adaptation to be shown at the fan event "Jump Anime Tour" later this year. Jump Anime Tour is an event that takes place in several big cities around Japan (five this year) where anime is shown on big screens for invited fans. Previously, all manga that were featured in Jump Anime Tour eventually got TV anime adaptations, though it did take time for some to happen (e.g., Toriko was shown in Jump Anime Tour in October 2009 but the TV anime adaptation started only in April 2011).
