Discotek Media has announced its Blu-ray Disc home video release of the Sister Princess anime series suffered a manufacturing error that resulted in episodes 11-13 of the anime with missing subtitles. The company stated that it is working on a new disc that corrects the error, with plans to ship the replacement discs once they are ready.
Discotek plans to have Right Stuf automatically ship the fixed discs to customers once they are ready. The company asked those who purchased their discs from other vendors to email the company at firstname.lastname@example.org with their purchase information and address so that it can send a replacement disc.
The company released Sister Princess and Sister Princess: Re Pure on separate Blu-ray Disc sets on June 26, 2018. The first season has both English and Japanese audio tracks, while the second season is subtitle-only.
