Heaven's Lost Property Final – The Movie: Eternally My Master (そらのおとしものFinal) is a 2014 Japanese anime film based on the manga and anime series Heaven's Lost Property by Suu Minazuki.
Synopsis
The scene opens with the Zeus' destruction above Synapse, Tomoki calls for Nymph to return immediately; unfortunately Ikaros responds that Nymph isn't coming. Tomoki commands Ikaros to take him straight to Synapse as the Earth's surface deliberately vanishes. While flying towards Synapse, Ikaros tells Tomoki a story how long ago due to malfunction she was once ordered by a "boy" to attack Synapse out of desperation. Remarking a dying Sugata, Ikaros' body begins burning away because of a device installed within her whenever she approaches Synapse without permission. Having second thoughts, Tomoki orders Ikaros to go back but cannot since there is nowhere else to go to.
The film shifts to where Tomoki wakes up by Ikaros who attempted to kiss him. Tomoki has a rough morning when Nymph invites him on a date, with Astraea and Chaos joining in. Then meets up with Sohara as Chaos questions what a date is. Meanwhile, Hiyori visits Ikaros to see how well she's cultivating watermelons, and then Sugata and Mikako come over to interrogate the existence of Synapse or about Hiyori's return. Though Ikaros defies anything regarding Synapse, Hiyori reveals the reason of her "return" was due to Tomoki's unique existence in the particular world they are living in now. Sugata concludes the world continuum is all connected to Synapse. As everyone comes home, Tomoki wonders why Ikaros doesn't show emotions and thinks it because of the imprinting chain. Nymph and Astraea get into a sister fight. Tomoki is getting tired of the troublesome routine and tries to kick them out but they shout his own words back at him that Angeloids are freeloaders. Tomoki then breaks Ikaros' imprinting, with Daedalus and Sohara muttering their dismay.
