Arata naru Sekai: Kako-hen

アラタなるセカイ 過去編

In a far-off future where the majority of adults have mysteriously disappeared, leaving just a handful of guardians to care for the remaining children, a team sets out on a journey back through time to find and stop the root of humanity's collapse. A young boy sits in a movie theater, typing on his phone, doubtful about their odds. "Altering the future with only five kids? We're seriously underprepared," he messages. They wonder if they really have traveled to the past, since they have been stuck inside the theater ever since they arrived.
