Storywise, Terumi can't just transform into Black Susano'o. This is why he decided to search for Hihiirokane - to kill Hakumen with it, and take his armor.

I think the final boss will be either BlackBeast!Ragna, or Amaterasu Unit with its wielder. Or maybe something new from the Azure gate. Makes sense storywise:
 * Ragna is about to turn into a Beast, and he rejected Amane's offer to extend his time as a human a little more.
 * They definitely need to put another god in the Amaterasu Unit, since someone has to create a new world from Embryo, and manage it without driving it into a timeloop. But I guess she won't just leave the Unit if they ask her, so they'll have to remove her from the Unit by force.
 * Noel says that the Azure gate should never be opened, she even got rid of her power to make sure it stays closed, and this makes me wonder what kind of terrible things might happen if the gate will be opened.
