An official website has opened for an anime adaptation of visual novel Grisaia: Phantom Trigger on Saturday. Akio Watanabe (Kami nomi zo Shiru Sekai) will serve as the character designer and chief animation director, while Ryuichiro Yamakawa (Grisaia no Kajitsu) will produce the anime.

Grisaia: Phantom Trigger takes place after the existing Grisaia trilogy, and features a completely new group of heroines as well as a new protagonist.
