The trailer is basically the opening cartoon and song, and it looks really, really good.
The american localization was announced at Anime Expo 2018 at Los Angeles, and this is the identical trailer which was showcased on stage.
If you’re unfamiliar with the game, it’s a remake of a traditional romantic and mystery visual novel with dimension traveling themes by the late Hiroyuki Kanno. It was originally released in 1996 to get NEC PC-98, followed by Sega Saturn and PC interfaces. The movie itself premiered in Japan in the spring of 2016, and lovers of the genre have been waiting for a localization announcement ever since.
Personally, seeing a publisher picked up it brings a big grin to my face.
The game will launch for PS4 and Steam, and it is coming from 2019.
