What is the real body of Ba Wei in "The Dynamic Girl Bound by God"?

Tomoe was originally a fox with strong fighting capacity. Later, because he fell in love with a human woman, he entered into a contract with the fallen god, Black Mill, and wanted to become human. Because he failed to complete the contract, he was cursed by death and saved by the imperial shadow of the land god. Under his arrangement, he met and fell in love with Momozono Nanami and became an envoy of Momozono Nanami. Proud, black-bellied, evil and gentle, Tomoe finally became a human being and married Nai Nai.

More than 500 years ago, he was a monster with strong fighting capacity (once destroyed the Dragon Palace) and made bad friends with Akura Ou. Together, they can't even help God. However, Tomoe and Akura Ou have different personalities, and they don't like unnecessary killing. They once saved Miss Beaver in the teahouse. Later, Tomoe fell in love with the human women's snow trail. In order to become a person, she spent her life with Xuedao and made a contract with Ahriman. However, due to the death of the snowy road, the contract could not be completed and the spell began. On his deathbed, Tomoe happened to meet the Imperial Shadow and was saved by it. He forgot the past events related to the snowy road and became the god of the Imperial Shadow Shrine.

In fact, the person Tomoe liked in the past was born in Nai Nai, which crossed into the past. When we first met, Nai Nai traveled through the past for the first time, and his soul traveled to the snowy road, so Tomoe naturally thought that he met a woman named "snowy road". Later, Nai Nai was born to save Tomoe, who was dying because of the contract curse. When ontology crossed 500 years ago, Nai Nai thought that the so-called "feelings between snowy road and Tomoe" should not be changed, so when he saved Tomoe who was injured and fell by the river, he would always hide his existence and let people tell Tomoe that snowy road saved him.

Later, Mr Nai Nai returned to modern times. After eight years with Mr. Nai Nai, Tomoe saw the real snowy road where he was killed and fled for his life. Because Xuedao happened to hear the agreement between Tomoe and Nai Nai, she pretended to be Tomoe's "Xuedao" and sought protection from him for the sake of the baby in her belly.
