Who is the REAL Antagonist?

[Drakengard]

It could possibly be the Juubi but I would like a bit more background knowledge on it before I say anything else. From the definitions of antagonist that you would look up online though, Sasuke does seem to fit the role of it more than others.

1. a person who is opposed to, struggles against, or competes with another; opponent; adversary.
2. the adversary of the hero or protagonist of a drama or other literary work: Iago is the antagonist of Othello.

[Wood Release]

Juubi will be the final villain. Oro and Sasuke are my second guess.
