Elsa can be seen, walking around the snowy field. She was then found by Hans.
"Take care of my sister!" Elsa said.
"Your sister, she returned from the mountain weak and cold! She said you froze her heart! I tried to save her but it was too late!" Hans said.
"Your sister is dead! Because of you!"
The storm had suddenly stopped. Elsa was down on the ground, devastated by what she had done to her sister. Hans tries to kill her using his sword, but Anna managed to block his sword using her hand, but was unharmed and turned into an ice statue. Hans was then launched back by the impact.
"ANNA!" Elsa said.
Haruto and Nitoh soon arrived, followed by Kristoff, Sven and Olaf. She was hugging the frozen statue of Anna, and cried. But, then...
"Haruto! Look!" Nitoh said, as he points to Elsa.
There was a purple crack around her face, and it continues to fill in her body. Haruto quickly transformed into Wizard and approaches her. But, the frozen statue of Anna started to unfreeze, until she was alive again.
"Elsa? What happened to you?" Anna said.
"Hahahahaha! The plan was a success!"
Hans began to stand up and transformed into a Phantom. And summoned a bunch of Ghouls.
"Phantom!" Haruto said.
"Henshin!" Nitoh said.
"SET OPEN!"
Nitoh transformed into Kamen Rider Beast.
"Haruto, leave this Phantom to me! You go save her!" Nitoh said, as he rushed to battle.
"I won't allow you!"
He tries to attack Wizard, but Beast blocked him.
"If you want him, fight me first!" Nitoh said.
Haruto approaches Anna.
"Haruto, what happened to her?" Anna asked.
"She's in despair after you sacrificed yourself." Haruto said.
"What?" Anna shockingly said.
"But don't worry, I'll save her! Because I am the final hope!" Haruto said.
Haruto pulls out a ring and wears it on Elsa's left hand. He then switched the WizarDriver so that the hand faces left, and redirects her hand to the WizarDriver.
"Engage, Please!"
A magical portal appears and Haruto goes through it. Meanwhile, Nitoh managed to defeat all of the Ghouls and goes to fight the Phantom.
In Elsa's Underworld...
Haruto managed to arrive in her underworld, he then saw a scene where she and Anna, when they were kids, building up a snowman. It also demonstrates her ice powers.
"So, this is her underworld..." Haruto said.
But then, a purple crack surrounds it and the Inner Phantom came out of it and starts to ram around the Underworld. Haruto pulls out a ring and activates it.
"Drago Rise, Please!"
A dragon appears and starts to fight the Inner Phantom. Haruto used his motorcycle to chase them, until he transformed his motorcycle, so that he can control the dragon.
In the real world...
Nitoh still had a hard time defeating the Phantom. He then pulls out a ring.
"Hyper, Go!"
Beast has transformed into Beast Hyper. He was able to damaged the Phantom long enough to use his finisher on him.
"And now for the main dish!" Nitoh said.
"Hyper Magnum Strike!"
Beast then shoots the Phantom and killed the Phantom. A yellow light then goes to his Beast Driver and devours it.
"Thanks for the meal!" He said.
Back at Elsa's Underworld...
The Inner Phantom still caused some damage, but Wizard managed to weaken it. He then pulls a Kick Strike ring.
"Very Nice! Kick Strike! The Best!"
Dragon began to transform into a foot and Wizard kicked it to destroy the Inner Phantom.
In the Real World...
A magic portal appears and Haruto came out of it.
"Whew!" He said.
"Haruto!" Anna said.
"You saved me. Thanks" Elsa said.
"No problem. I won't let anyone go to despair, especially loved ones!" Haruto said.
"An act of true love will thaw a frozen heart!" Olaf said.
"That's right! Love! Of course! Love!" Elsa said.
"Elsa?" Anna said.
"Love."
She then used her powers to lift the snow and ice away from Arendelle, thus bringing the place back to normal.
"I knew you could do it!" Anna said.
"Wait, how come she still had her powers? Didn't you destroy her Inner Phantom?" Nitoh asked.
"Apparently, her ice powers did not came from her Inner Phantom. She was born with it. So, destroying her Inner Phantom will not remove her ice powers." Haruto explained.
"I see..." Nitoh said.
They then saw Olaf melting.
"Hands down, this is the best day of my life... and quite possibly my last." Olaf said.
"Oh, Olaf. Hang on, little guy." Elsa said, as she used her power to create a cloud that keeps him alive.
"Hey, my own personal flurry." Olaf cheered.
Kristoff and Nitoh sees Hans getting up to his feet. Nitoh was about to transform but Haruto and Anna stops him.
"Let her handle this." Haruto said.
"Anna? But she froze your heart..." Hans said.
"The only frozen heart around here is yours." Anna said, as she starts to punch him in the face.
Hans then fell in the fjord by that punch. Elsa and Anna then embraced each other. Kristoff, Haruto and Nitoh stood smiling.
