Welcome to the Thirteenth Goddess, an adult fantasy visual novel and adventure and monster-management simulation game about pretty Monster Girls called Taerin — inspired by the unique world of real-life Aotearoa, New Zealand!!


You wash ashore on a world at war...
Around you, the Twelve Goddesses tear each other apart, and a nameless corruption creeps into the heart of every Taerin, stoking a lust that can't be sated...

Bond, Cleanse, and Corrupt...
A nameless corruption lives inside every girl. Bring her home with you, and explore a hundred options to wrestle her mind back from the dark! Teach her what love looks like... or don't! Maybe you like her better as a pink-glowing-eyed abomination?

A thousand different scenes...
A dynamic VN text-based sex system that changes every time you engage with it. Choose how you want every scene to play out. Different personalities, different species, different routes... Your girls will evolve as you do — or more like... as you screw.
