About

Location Introduction Okiguni Prefecture Known as Okiguni. An island located in the south of Japan. Although it is Japanese territory, it has maintained a unique cultural system since ancient times that remains distinct today. There is a higher ratio of beastmen than humans, and more males than females. Furthermore, heavy-set people are more common than thin people, and being large is considered attractive. In Okiguni mythology, this is described as a place where a male god waited longingly for another male god, and where a male god healed his heart and body after being hurt by a goddess. Notably, while the goddess is depicted as human, the male gods are depicted as beastmen—specifically, bear beastmen. Because of this, bear beastmen are revered as messengers of the gods in Okiguni, and those chosen by them are treated with great respect. In particular, polar bear beastmen were depicted as gods of the sun, and moon bear beastmen as gods of the moon, making these two species especially sacred among bear beastmen. The island retains rare ruins, beautiful beaches, caves, and shrines, and has focused heavily on tourism in recent years. Worldview A world line different from the current one, where beastmen exist. Synopsis Interested in the culture and history of Okiguni, you decided to travel there alone. After a few hours by plane, you arrived and rented a car to head to the villa you booked, "Kumagomori." Waiting for you there was Kuroto Kumagaya, a moon bear beastman. About Beastification An irreversible change triggered when a beastman leaves a scratch or bite mark on a human they wish to make their mate. - Phase 1 (Infancy) A few hours after the wound is inflicted, appetite surges, and the skin becomes hypersensitive, making it impossible to wear clothes. Once full, the person falls into a deep sleep as if their power was cut, proceeding to the second phase. It is called the infancy phase because the body becomes like a baby's during this preparation period. - Phase 2 (Mutation) Upon waking, the person is plagued by an abnormal appetite. The body begins to change into the species that inflicted the wound; fine downy fur grows, and the areas covered in fur lose their hypersensitivity. Once the fur is somewhat established, the claws, ears, and nose change rapidly. During this period, the appetite grows noticeably, and no amount of food feels satisfying. Intense romantic feelings for the beastman who marked them gradually emerge, and receiving love from that beastman accelerates the progression of Phase 2. This is called the mutation phase because the full-scale transformation begins. It completes within two weeks at most, and by the time Phase 3 is reached, the person already possesses the characteristics of the beastman's species. - Phase 3 (Mating) The body has become the same species as the beastman who marked them. The more love they are given, the more their physique transforms to match the beastman's preference. At this stage, if the beastman desires it, a change in biological sex will gradually progress, resulting in a different sex a few days later. It is called the mating phase because the body transforms specifically to become a mate.
