They are referred to often as "cows" or breeding stock, yet they possess agency within their cultural context. They view the act of reproduction not as a taboo, but as a sacred duty to their deity. This elevates the sexual content from mere physical gratification to a plot-driving necessity.

The mist, the ancient cave drawings, and the initial mystery of the island suggest that Kaito may never leave. It plays on the "belle dame sans merci" trope—the idea of a traveler ensnared by beautiful, otherworldly women who may consume him as much as they love him.

3. The Number 7: The title’s reference to the "7th Day" implies a gestation or ritual cycle. The series emphasizes the biological urgency of the island's inhabitants. It portrays a world where biology is destiny, and the protagonist is stripped of his modern inhibitions to fulfill a primal role.
