It literally contradicts everything the manga and anime show

No, Hagoromo didn’t have the byakugan

Indra was the first sharingan user and no, his ms was a swirl pattern, not sasukes ms and abilities, the only thing we know from Indra is that his susanoo was purple

No, ashura didn’t have wood release nor he created the rasengan, hashirama was the first wood release user and minato created the rasengan based on the bijuu ball

Hagoromo didn’t weaponize elemental abilities nor he had a susanoo

Hagoromo absorbed the chakra of the juubi, he did not immediately create the bijuu, it was ashura who gave hagoromo the idea of creating the bijuu in the first place

Why do you guys seriously believe a filler that contradicts everything as canon?
