Sora no Otoshimono Final: Eternal My Master

Tomoki Sakurai has always wished for a peaceful life, yet his days have become inseparable from Ikaros and the other Angeloids who descended from the mysterious world of Synapse. As the bond between Tomoki and Ikaros deepens, he becomes increasingly troubled by the master-and-servant connection that prevents her from choosing her own path.

Tomoki wants Ikaros to live freely rather than obey him forever, but freedom is far more frightening to her than he realizes. While their feelings finally begin to surface, the secrets of Synapse and the danger surrounding the Angeloids push their relationship toward a painful decision that neither of them can avoid.
