Uitsualnemetia

The Onkami (Great God). Also the name of the religion of many countries.

The result of a pact between a powerful, ancient, and mysterious entity that was discovered as a fossil in the modern day and a young and fatally curious archaeologist. Uitsualnemetia asked Mutsumi to destroy him when he could not stop killing the scientists at the research facility. Mutsumi failed to destroy him, so she sealed him in the Earth instead. However, he was split into two halves (a "good" half and an "evil" half) before he was sealed. The "good" half became Hakuoro and the "evil" half possessed Dii.
