So i figured out the story of the 3 gods...
So i figured out the story that the kabane guy was talking about concerning the 3 gods that fought death. Apparently when izanagi escaped from his wife izanami in yomi (hell) she said that she would kill 1000 of his children every day. Izanagi then states that he will give birth to 1500 then. Im assuming that since amaterasu, tsukiyomi, and susanoo were born after izanagi purified himself after escaping yomi that theyre taking on their father's fight. This of course is only my assumption so i would love to hear some theories or thoughts.
