Sekai Project announced at their Anime Weekend Atlanta 2016 panel that they will be publishing Serment Contract with a Devil.

Featuring 4 girls who have been revived by the a devil. The player will assume the role of one of the girls who must pay a large sum of money for what the devil has done for them.

The publisher adds, "If the payment comes even one day late, the heroine will return to the afterlife. And so her light-hearted, comedic adventure to save up enough money before the deadline begins".
