Frontwing announced on Thursday that it has greenlit a sequel to the anime adaptation of its Grisaia: Phantom Trigger game. The sequel will tell the story of the "Vol. 3" game. Frontwing will launch a crowdfunding campaign for the anime in June in order to produce a better quality product.

The first anime opened on March 15 at Tokyo's EJ Anime Theater Shinjuku and at four other theaters in Japan.

The anime's first two episodes were originally slated to debut simultaneously in 2018, with region-free Blu-ray Discs slated to ship last December. Rewards for crowdfunding backers have not yet shipped. The English dub will be included on the Blu-ray Disc release. Each episode was originally planned to be 60 minutes long and would adapt one volume of the original visual novel.

Anime director Tensho founded the new animation studio Bibury Animation Studio to produce the anime as its first work. Tensho also wrote and supervised the scripts. Akio Watanabe , the original character designer for the Grisaia franchise , served as the anime's character designer and chief animation director. Ryuichiro Yamakawa planned and produced the anime. Frontwing funded the anime on its own instead of using a production committee.
