World War R
At Haven, Cinder wakes up and sees both Mercury and Emerald and told her what happened when she was frozen by Ruby and a few creatures of Grimm round up to the remains of the forest in Haven before the dragon reawakens.
Cinder: At least those idiots don't know where we are right now.
Mercury: Even their school is finally destroyed, no one is strong enough to defeat you.
Emerald: But what's worse is that the dragon is frozen and I believe the students in that school are in for vengeance.
Unknown to them, a few airships arrived and started to annihilate all the creatures of Grimm, until they realized it but a few familiar faces wanted to give them a piece of their own mind, vengeance.
Diana: There they are, alright Nathan, fight Mercury, and Ginny, you handle Neo!
Nathan: On it!
Ginny: You got it!
Diana: Russ, whatever you do, give Emerald what you've got!
Russ: I can handle that in my sleep!
Elsewhere, Ruby went to the transmit tower, through the ruins of Beacon, to kill the dragon once and for all. Weiss is also there to be with her just in case. Meanwhile back in the battlefield of Haven, Nathan activated his semblance and out struck Mercury's fake legs while Ginny defeated Neo by using her semblance. Russ however, is ending Emerald's days of hallucinations. Emerald tried to beat Russ with her semblance, but Russ avoided all of her hits until she finally landed one by knocking off his sunglasses, but what she saw are his solid white eyes glowing, Russ is using semblance. Diana confronted and battles Cinder in an unknown empty location, Cinder used the Fall Maiden powers to kill her like what she did to Pyrrha, but it never worked on Diana.
Diana: You were wrong. When Pyrrha said that you believe in destiny, you're afraid of it.
Cinder: I killed the invincible girl!
Diana: What if the powers never belonged to you? What if it only worked on the warm hearted? Come on Cinder, let's finish what you started... Together!
Diana and Cinder used their charged blasts against each other but it's equally matched, back at the tower, Ruby entered the belly of the beast and used her inner power of the silver-eyed warrior and blew up the dragon, destroying all the Grimm creatures, Nathan killed Mercury by shoving his burning fist through his chest, Ginny impaled Neo with her earth-bending semblance and Russ killed Emerald with a Metsu Shoryuken. The death of the dragon slowed Cinder's power and Diana threw her lance like a javelin impaling Cinder, killing her and absorbing the Fall Maiden powers to the lance. All the huntsmen and huntresses reunite to Diana and Cinder's battlefield and began to discuss about what happened.
Ginny: Why didn't it worked for her, the powers of the Maiden?
Diana: It only works on the warm hearted. When she killed Pyrrha, she said she can use it in ways no one has ever imagined, but the truth is... It never worked for the cold hearted. It was Amber, who knew about the legends and memories of each maiden skill. She believed in destiny and judge every spirit of our own. The powers saw great judgement in Pyrrha and chose her to be their current Fall Maiden, and she was never afraid of her own destiny, but when she died, the silver-eyed warrior saw what happened and unleashed it's incredible power, the maiden's power felt it and found its avenger.
Nathan: So that means...
Diana walked up to Ruby, who arrived with Weiss after killing the frozen dragon, and offered her the power absorbed lance.
Diana: Ruby Rose, do you want to take this responsibility of being the new Fall Maiden? I'll teach you how to use it and learn its legend.
Ruby: I accept.
And with that, the maiden powers are suddenly transferred to Ruby and began to bond with it. She is ready to take the responsibility of the Fall Maiden.
