@Alcahona: They weren't able to cover up Trihexa's attack, the media caught it, the damage is too great and Azazel's memory eraser has revealed too much memory erasing can leave brain damage. Both times it was used there was something that everyone still remembered.

Plus we learned that the war being fought in the EX future? Rizevim caused it by using Agreas to basically give them a reason AND way to invade, one that lets them avoid Great Red entirely so he can't stop them for getting in way and staring at him. The supernatural world does need Human faith, so if they can't keep Humanity safe... they're dead anyways.
