Yesterday wo Utatte Extras

Yesterday wo Utatte Extras is a supplementary original net animation consisting of six distinct post-credit scenes. These brief segments were produced to adapt additional manga material that was ultimately left out of the primary television broadcast, offering fans further insight into the source material beyond the core narrative. Rather than being included in the standard home video releases or attached to every installment, these extra scenes were distributed through a specific streaming strategy. They were made available exclusively on the AbemaTV platform, premiering directly after the conclusion of select episodes throughout the series' run. Viewers could access these bonus adaptations following the broadcasts of the first, second, third, fourth, ninth, and twelfth episodes, providing a staggered release of supplemental content tied directly to the main show's airing schedule.
