Gunbuster is a 1988 anime OVA directed by Hideaki Anno and animated by Gainax.
It premiered between October 7, 1988 to July 7, 1989.
Although the series has been released on home media in America several times, all of it's releases were sub-only. On January 31, 2023, Discotek Media announced that an English dub of the series by Sound Cadence Studios would be included on the Blu-Ray release which was released on May 30, 2023.
Synopsis
When the space aliens killed Noriko Takaya’s father, she swore she’d go into space to have her revenge. Yet being accepted into the prestigious Okinawa Girls’ Space Pilot High School doesn’t solve every problem. Looked down upon as the daughter of the admiral who lost, and having a stark lack of talent that prevents her from piloting a machine, Noriko’s hopes for the future don’t seem bright. But then, when the two candidates going into space are announced, Noriko’s surprised to find her name right next to the star of the school (and Noriko’s own idol), Kazumi Amano. Has Noriko’s hard work paid off? Or is there more to Coach Ohta’s reasons for selecting her? Most of all, is Noriko really ready for the horrors of space?
The reason why all prior video releases of the show were sub-only was because Gainax had lost the original dubbing track, meaning that the only way to have dubbed the series would've been to split the voice and audio tracks.
