RWBY: Ice Queendom

Ruby Rose, a girl who admires Huntsmen, along with her elder sister Yang Xiao Long enroll into Beacon Academy, a training school for Huntsmen. Her talents were discovered by Ozpin, the school’s Headmaster.

Young boys and girls wanting to become Huntsmen gather to attend Beacon’s entrance ceremony. As everyone gathers, a shy Ruby is being urged by Yang to make friends. However, after being dismissed by Blake and angering Weiss, she gets depressed.

Based on the test results, Ruby, Weiss, Blake, and Yang form "Team RWBY," and their school life beings. Weiss, unaccepting that Ruby was chosen as team leader, appeals to the professor that she is more capable.

On her snowboard, Ruby slides down the snowy field. Weiss, possessed by the Grimm "Nightmare", created a world in her dreams, which is a reflection of her mind.

Attacked by Weiss and finding herself cornered, Ruby is rescued by Shion. Even after she had awakened from the dream, Ruby starts to feel uncertain having heard Weiss’ aggressive words. However, she decides to take on the challenge once again.

Ruby’s party reaches the inner depths of the dream, but Nega-Weiss attacks trying to eliminate Blake. Blake has a difficult timing fighting Weiss’ relentless attacks and is also hurt from hearing harsh words.

With advice from Team JNPR, Penny, and Sun, Ruby’s party decides to try a new plan. Along with Jaune, who had acquired immunity toward the "Nightmare", the four sneak into Weiss’ dream.

The city falls along with the deformed Sillies and the robot soldiers affected by the bugs’ rampage. As the situation gets chaotic, Nega-Weiss shows up with a giant statute of Nicholas, capturing the Sillies one after another.

In the dorm room, Weiss, smiling, hands Ruby a cup of coffee and the two talk. Weiss leaves the room saying, "There is a reason for everything." It was Ruby’s dream, who was possessed by the "Nightmare" due to her weakening spirit.

Blake’s plan to make the "Nightmare" possess Blake so that they could confront Nega-Weiss was much too dangerous. Yang objects but Blake was firmly determined. Shion and Ozpin decide to accept her plan, considering Weiss’s urgent condition.

As Yang fights the statue of Nicholas, Jaune and the Sillies fight the statue of Jacques. The robot army that had been created from Weiss’s nightmare fight the deformed White Fang which had been created from Blake’s nightmare.

Defeating the "Nightmare" and released from the nightmare, Team RWBY and Team JNPR resume their school life. The teammates had opened their hearts to each other more than before.
