It’s been a long time coming, but Grisaia no Kajitsu is finally out! Koestl gives it an amazing translation, and everyone on the team came together to make it a great release. Head on over to TLWiki to grab a the patch. You’ll need the game installed prior to installing the patch, it doesn’t matter which version you have installed.
Edit: We’ve released version 1.1 of the patch, which fixes reported issues with the first release. Be sure to grab the latest version!
Edit2: The patch is no longer available now that the official release has been announced. Thanks to everyone who supported us!
