Films starring the Ensemble Square idols have been nominated for the Idol Film Festival (IFF), an annual festival held in New York City, and representative idols are selected to attend. The boys jet off to NYC to attend the festival and reception party, and afterward, head out on the town to see the sights and sounds. But a suspicious shadow is creeping up on them…

To save his mother, a kind-hearted boy and his tiny daemon friend set out on a journey across post-apocalyptic Japan as dark forces close in.

At the end of the last summer vacation of high school, Youta Narukami spends his days preparing for the university entrance exams, when a young girl named Hina suddenly appears, proclaiming herself as the "god of omniscience." Youta is confused and does not believe Hina when she tells him "The world will end in 30 days." After witnessing Hina’s God-like predictive ability, Youta begins to believe her powers are real. Hina, who is innocent and childlike despite her supernatural powers, decides for some reason to stay at Youta’s home. Thus begins the start of their lively summer before the end of the world.
