The Demon Child Mother found in the present world is definitely not the true body of the deity.
It's likely that when this dilapidated shrine was still intact, it was protected by the divine power of the Ghost Mother Goddess.
According to the elderly of Kitamurayama District, this shrine seemed to have truly used this divine power in the past to guide and release the spirits of prematurely deceased children. It appears that many parents from nearby areas brought their young children who had died prematurely here for burial.
The "Demon Child Mother" we see now is probably the manifestation of that residual divine power.
As for why she now seems more like a youkai—
It's likely due to the spirits of the premature children and resentment within the cemetery, which have influenced her.
Ssszz—!
