Jain no Ikenie: Shokushu-hime Altea

Jain no Ikenie: Shokushu-hime Altea is a standalone release of the Tentacle Princess Altea 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 follows the eponymous Princess Altea, who is known across the kingdom of Aquila for her beauty and purity. Though once revered by the people of Aquila, Altea's subjects turn against her when the kingdom suffers extreme water shortages, electing to have her sacrificed to the wicked sorcerer Aldebaran in an attempt to reverse the drought. While trapped in Aldebaran's mansion, Altea meets Deneb Swan, a princess from another kingdom who had also been sacrificed to the sorcerer. The two princesses must work together to escape the mansion and regain their freedom - though it is unlikely that either will leave with their purity intact.
