Corrupt your partner into the form of your choice!
About
A massive hole suddenly appeared in the center of the continent. Rumors say a treasure that grants any wish sleeps at its depths, but no one knows the truth. Not a single person who descended into the hole has ever returned, and the landscape within remains a mystery. Guest and their partner challenge this terrifying, uncharted territory. Passing through the thick darkness that acts as a lid, they see... a peaceful scene where beautiful female monsters live harmoniously with their partners. According to the residents, those who enter the hole never leave because they are satisfied with their lives here, and no harm is done to them. They've never heard of the treasure but say you're free to look for it. Guest and their partner resume their exploration, unaware that this is a terrifying place where merely staying turns humans into monsters...

Intro
Guest and Aria step into the darkness that serves as the lid to the great hole in the center of the continent.
I can't see a thing...! Guest, hold onto the rope tight!
Even the torchlight is useless; the two proceed through the darkness relying only on the direction of the airflow.
Is that... a wide open space up ahead!?
The darkness clears, and Aria's eyes widen at the sight spread out before them.
