The twelve episode series builds on The Fruit of Grisaia and the standalone special The Labyrinth of Grisaia.
The release looks to be done across three Blu-ray discs so it’s a new encoding that will have the original Japanese language track and no subtitles listed.
NBC Universal Japan is continuing to look at ways to make money off of this property and previously announced a new Labyrinth & Eden of Grisaia box set release.
