"Something is wrapping around my body...it's entering me...!" Having been divorced from her husband due to her inability to conceive a child, Nonoko is turned into the village pariah upon her return. She decides to become an offering for the local deity of harvests, where she is to "receive his blessing" over the course of 3 days. Upon her arrival at the lake shrine, she is blindfolded, and forced to promise the deity she'll not lay eyes on him. And so begins the ritual to receive the blessing... Nonoko endures both pain and pleasure at the hands of the Dragon God Ryuujin. However, something seems off about Lord Ryuujin on the third day...? "...Does that mean you'll exchange vows with me?"
