aka Grisaia no Kajitsu, slated for October broadcast.
From ze Wikipedia:
Trying to become something that he isn't, Kazami Yuji transferred himself to Mihama Academy –- a school with only five female students and prison-like features. He was told that every student in this school have their own 'circumstances' (himself included) and that he is not required to do anything about their situation as he asked for a 'normal' student life. Will Yuji find his solution here in Mihama Academy?
That's a pretty weak, generic intro, I think. Here's a better one, a la Terek:
Kazami Yuji, a former soldier, is suffering from the mental fatigue of his work and the horrors of his past. His superiors arrange for him to enroll as a student in Mihama Academy - they hope some simulation of normal life will help him preserve his sanity and regain his humanity. But Mihama Academy isn't an ordinary school, and its student body - consisting of only five girls - aren't ordinary people. Can this group of weirdos really have a normal school life?!
I've played the VN, or am in the process of playing. The story is kind of retro in how there's five routes, one for each girl, but no "secret route" or "meta route". A lot of VNs these days follow the Ever17 mould and have a secret/true route you get to once you clear the character routes, and Grisaia doesn't do that, which is to be commended. The routes are of varying quality and entirely deal with the girl's pasts. If you are misanthropic and don't care about other people, this isn't a story for you. But if you like character drama, some funny action scenes, and Wikipedia-style infodumps on bizarre paramilitary misadventures, this is your cup o' joe.
I finished one route (Michiru's) and it's pretty good. The art is about 8/10ish and I think the anime will be similar. It's got a wide-screen presentation similar to Muv-Luv Alternative which makes it feel more cinematic than your typical "dating sim romcom!".
It looks like Takahiro Sakurai was picked to voice Yuuji. That's a safe choice, although Yuuji himself was un-voiced in the game so it might be jarring. I have no idea.
Grisaia's been hyped by a bunch of VN junkies for reasons I do not quite understand yet. I think it's a solid title, but not an endearing classic. Still, I think if all goes well we can expect ToraDora! level quality out of this show, which would easily make it one of the best adaptions since 2010-2011 (which featured Madoka, Fate/Zero, PenguinDrum, among other things).
