The film opens with Tomoki and the rest of the New World Discovery Club in the middle of another unusual, if not typical, situation. A giant chicken, about whom Tomoki apparently forgot, wreaks havoc on Sorami City, so Tomoki, via one of Ikaros' cards, has Sohara grown to giant size to fight the chicken, which she defeats, but then promptly steps on Tomoki for staring up her skirt. The film then switches to Daedalus who explains more about the Angeloids and their history, and then to a scene where an Angel is asleep in a pod. On Earth, Hiyori Kazane, a resident of Sorami City and the film's main heroine, introduces herself and explains how she met and fell in love with Tomoki, while also narrating about how she took part in several events from the two previous anime seasons, all the while observing Tomoki and his friends, and even becoming acquainted with most of them.
