I came to see the water god, but... "I'm going to take your virginity." Devil x Sacrificial Girl.
A certain village suffers from frequent floods every year.
To appease the water god, human sacrifices are made to the river each time.

This year, Tiana is chosen to throw herself into the river to fulfill her mission as a sacrifice for the village.

While being carried away by the river, she suddenly arrives at a village called Lumina Village.
She meets the demon Ashley, who calls himself the village's guardian, and is guided through the village.
The village is a place where those who wander between life and death by the river end up, and many people live there.

Tiana cannot return to her village, so she must perform a certain ritual to enter the village.
The "Rite of Deprivation" is a ritual that a maiden who has been ordered to be sacrificed must undergo.
Tiana is forced to perform the ritual in a different way than before, but what is the method?
And where on earth is the water god...
