Kemonogami

Kemonogami (ケモノガミ), also known as Beast God, is the name of a type of lifeform in Digimon Survive.

Habu Kazumasa stated that in the story background of Digimon Survive and some other Digimon media, Digimon were not born as a result of humans creating computers, and instead always existed, living alongside humans, though in another dimension, becoming visible to humans once they created computers and digital technology. They may have been manifested through magic or sorcery, through the ancient art of, subjugating them as , , or s, but was then accomplished digitally, making them Digital Monsters. This indicates that the plot of Survive conceptually takes place before said creatures (Kemonogami) became Digimon as a result of said technology.

Kemonogami are split into Moral, Wrathful, Harmony, and Free. These are similar to Attributes of other media, where those are instead named Vaccine, Virus, Data, respectively. Free shares the same name.

In the English release, Kemonogami are stated to evolve rather than digivolve. This is possibly because they are not Digimon but rather Kemonogami, and as such the term digivolution wouldn't fit.

Digimon Survive
The Kemonogami are a type of lifeform that exist in an alternate World to the Humans'. In some places, Humans came to worship and/or fear them and as such would provide them with children as sacrifices in the hopes it would keep them safe.

In one small village, the locals created a shrine dedicated to worshipping the Kemonogami though eventually barred anyone from going near it due to many people going missing near it. Some referred to this as being "spirited away".

Some Humans would also find their way to the Kemonogami World in other ways, such as Momotsuka Takuma and his friends ending up there after walking through a tunnel on their historical studies extracurricular activities camp.
