After one more look at the OP, beautifully animated but for the fact Anna and Cosette lack toes (that always bothered me), we go right into the final boss battle. Orpheus packs a punch and has a suitably calm yet menacing voice, but by making it a two-against-one fight, she allows herself to be distracted by a kick to the fact from Takt, allowing Destiny to blast the top half of her away.
She eventually regenerates, but it takes enough time that Takt is able to continue on to Sagan. It then becomes a duel between Destiny and Orpheus, and the lack of a frail human in their midst means they can really let their bedazzled hair down and have a proper brawl, captured with all the requisite concussive Mappa/Madhouse sakuga.
Turns out Orpheus really is the final true boss; Sagan can’t do anything but try to convince Takt that his cause is right and just. Oh, and the show finally lets us in on the secret of why exactly he’s doing all this: he wants to lure all of the D2s in the world to a sacrificial North America so he can take them all out at once, thereby saving the remaining six populated continents. Uh, my dude … Antarctica was right there!
Turns out both Heaven and Hell, and thus Orpheus, aren’t really trying to save the world so much as save their Conductor, whom they love despite his fatal flaw of choosing the wrong continent to sacrifice. Just as Takt isn’t hearing Sagan’s excuses, Destiny most emphatically Does Not Care what Orpheus says or thinks, and somehow powering up, manages to pummel the hell (and heaven!) out of her. Destiny just wanted it more, I guess!
Destiny joins Takt, cementing Sagan’s defeat, as Takt uses her sword to kill him, which shuts down all of the D2s running amok in the crippled Symphonica. Sayonara Sagan…you were never much of a character, and the little bit of pathos the episode tries to squeeze out of your situation in the eleventh hour didn’t really work. You were just another of the dime-a-dozen villains populating lesser anime. Takt Op. Destiny deserved a better baddie.
It’s main duo won me over, however. Destiny has been showing more and more emotion as she’s come into her own as an individual and not just an musical alien inhabiting Takt’s dead soul mate. She basically becomes another soul mate to Takt, staying beside him, holding his non-existent right hand as they lay on the beach, then giving him a farewell kiss before vanishing in a cloud of rose petals. It’s a beautiful scene filled with bittersweet love.
That brings us to the brief epilogue, which indicates Takt made it into suspended animation alive. Anna has joined the Symphonica, trading her belly-bearing tops for the organization’s marching band-y uniform. She also looks after a gold trinket with red trim, the only thing Destiny left behind, and which seems to allow Anna to transform into the next Destiny. As her out-of-left-field kiss hinted, she’s dedicated herself for being there for Takt when—not if—he wakes up. There’s still a lot of D2s out there.
