Jain no Ikenie: Mashikyū Tsukai Bianka

Jain no Ikenie: Mashikyū Tsukai Bianka is a standalone release of the Saint Bianca's Ceaseless Conception story which was previously released as part of the visual novel Jain no Ikenie: Shokushu-hime Altea & Mashikyū Tsukai Bianka Owari no Nai Jutai. Throughout the game, the player is periodically tasked with making choices which may influence where the story goes. The game features voice acting and contains graphic depictions of sex, mostly involving tentacles.

The story takes place in a kingdom where a holy saint named Bianka is preparing to fulfil her destiny to conceive the Child of God and give birth to the one who is prophesized to defeat a great demon threat. However, before the prophets can bring their plans to fruition, Bianka is kidnapped by a demon lord, who plans to impregnate her with the seed of a demon instead. To this end, Bianka is violated by tentacles - lots and lots of tentacles - and she must find a way to escape the torture before it is too late.
