Atlus has been a recent publishing partner with Japanese developer FuRyu, releasing some of their titles such as The Legend of Legacy and Lost Dimension in North America. Atlus has announced that they are working with them once again to release one of their latest titles, Caligula, to Western audiences.
This news was announced just following the events of E3 2016, so there's not much information about the game revealed thus far, although the publisher did reveal some information about the game. It will be released exclusively as a digital download title for the PlayStation Vita, but Atlus will be releasing it both in the Americas and Europe next spring.
In addition, they will be keeping the original Japanese audio intact, so there won't be any English dub included with the title. They noted that more details will come later, but for now there's some screenshots below from the Japanese build of the game.
