Sakamoto really need to oust that Asaki in JAA hopefully. That guy's the hidden antagonist all along. I just cant take the fact that the Order cant even question their own missions as if they are robots and wont even decide if its right or wrong. Hopefully that cycle of usurpation of power and betrayal would finally end with Sakamoto taking over the JAA.
Anyways, hopefully the latest backstory arc would shed light what happened to Rio and mastermind of it all
