Rather low-budget for a first episode; significant differences from the manga; delivery of the twist was decently done.

Basically the spiritual successor to Inferno Cop.

Kicking off with a 6~ episode backstory (including Meikyuu) was a little bit much, and I found the ending a little underwhelming, but I suppose the final scene made up for some of Grisaia's faults. Episode 8 was definitely one of the highlights of the season.
