Prologue
Ruby makes a brief cameo when the System XX begins observing and searching potential catalyst samples from all four different worlds.

Episode BlazBlue
In Chapter 2, Ruby Rose and Blake Belladonna attempt to ambush Ragna the Bloodedge to steal his Keystone but fail. Ruby introduces herself and Blake to Ragna and Gordeau and becomes excited to see their weapons. After Blake demands Ragna's Keystone, Ruby challenges him and Gordeau to fight. After Ruby and Blake lose the battle, Ragna tells the two that if they are going to be his enemy, then he will not be holding back, prompting Blake that they will remember that. But before Ruby can ask Ragna questions about his weapon, Blake tells her that they need to retreat, much to Ruby's disappointment.

In Chapter 7, Weiss Schnee teams up with Orie to receive Ragna's Keystone but fails. The girls then fight Ragna and Hazama but lose, prompting the System XX to transport them to another location.

Episode P4A


In Chapter 6, Ruby and Weiss launch a surprise attack on the Investigation Team and Ragna to steal their Keystones, under the false assumption that they are all villains who are aiming to destroy the world with the stones. After they lose to Yu and Ragna, Ruby and Weiss learn that they were tricked by their Keystone and that the other fighters are simply trying to find a way back to their worlds. The girls are then suddenly ambushed by Es, who steals their Keystone and transports them away.

After Yu and Yosuke defeat the awakened Keystone, Ruby appears in the newly created Phantom Field as one of the new transfer students at Yasogami High School.

Episode Under Night In-Birth


In Chapter 2, Ruby gets caught in Yosuke's bike accident and is stuck under him until Chie notices her and urges her friend to get up. As Ruby recovers, they are approached by Hyde, who mistakenly believes that Ruby is being bullied by Yosuke and Chie. He then summons Insulator, causing Ruby to get all excited and fervently ask Hyde about his sword. When the misunderstanding is cleared, they are prompted by the System XX to battle each other. At first, Ruby is against it but is later eager to battle Yosuke and Chie with Hyde when the System XX tells her that the Yasogami students have amazing weapons. After she and Hyde win, Ruby fervently pursues Yosuke and Chie as she wants to learn more about their Personas.

In Chapter 3, Blake follows Hyde to steal his Keystone but is forced to reveal herself when Hyde calls out to her to stop hiding. After Hyde tries to explain his suspicions to her about the tournament and that they shouldn't be fighting, Blake refuses to cooperate with someone she just met and prepares herself to take the stone from him. When Makoto appears, Blake mistakes the demi-human for a Faunus, and the two of them begin to bond over their shared sufferings of discrimination and their favorite foods. But as Hyde interrupts them, Blake joins forces with Makoto against him and Gordeau. After they lose, the girls are forced to retreat.

In Chapter 4, Weiss is attacked constantly by Azrael until she is rescued by Hyde. When Carmine demands Hyde hands over the Keystone and gives his desires to stay in the Phantom Field and torment Hyde, Weiss ridicules him for being nothing but an animal. She then teams up with Hyde to fend off Azrael and Carmine and they escape once they find their chance. After thanking Hyde, Weiss wishes him good luck as she parts ways with him.

After Hyde and Linne destroy the Keystone's true form, Ruby appears with Yu in the Kanzakai Scramble Tag Battle Tournament and later challenges Aegis upon seeing the robot's arsenal of weapons.

Episode RWBY


After the System XX informs Team RWBY about the rules of the tag battle tournament, the girls decide to split into two groups to cover more ground and find the Keystones.

In Chapter 1, Ruby and Weiss stumble upon Noel and Makoto and discover that they have a Keystone. They try to launch a surprise attack but are quickly discovered by the demi-human. When Ruby and Weiss ask for Noel and Makoto to hand over the Keystone, the latter makes an accidental slip that they have a stone of their own. As they are prompted to battle, Ruby and Weiss fight and defeat Noel and Makoto, causing the latter two to retreat with their Keystone. Weiss then becomes suspicious of the tournament and parts ways with Ruby to investigate.

In Chapter 2, Ruby finds Hyde with a Keystone and prepares to fight him for it when the System XX tells them that they can only fight in a tag battle. Upon Hazama's sudden arrival, Ruby teams up with him against Hyde and Carmine and emerge victoriously. She then receives Hyde's Keystone from Hazama before he takes his leave.

In Chapter 3, Ruby has a run-in with Rachel, who is fleeing capture from Platinum and Vatista. After learning from the latter two that the vampire knows something about the Phantom Field, Ruby is forced by Rachel to be her tag partner against Platinum and Vatista. After their victory, Ruby asks Rachel about their current environment and reveals her quest to collect the Keystones. She receives no answer but is instructed by the vampire to come to her after she collects all of the stones. When Rachel suddenly disappears, Ruby resolves herself to get the Keystones and get her team and herself back to their world.

In Chapter 4, Ruby is suddenly attacked by Hakumen, who demands her Keystone. She is then approached by Tager and is warned by him about using the stones to return home. When Ruby tries to defend her actions and says Rachel's name, she is forced to face both Hakumen and Tager. She tries to run but is stopped by Hakumen when he shows her the Keystone that Noel had before. Upon Waldstein's sudden arrival, Ruby teams up with him against the samurai and devil. After winning the battle, she steals the Keystone Hakumen has and makes her escape.

In Chapter 5, Ruby reunites with Weiss and shows her all of the Keystones that she has collected so far. They are then confronted by Orie, who demands they hand over the stone that was taken from Hyde. Weiss argues that they had worked hard to collect the stones, and it will be a waste to return them back. When Orie reluctantly teams up with Gordeau, the Huntresses prepare to fight them: Ruby is amazed at Gordeau's scythe, and Weiss wants to see Orie's power. After they win, Ruby and Weiss walk away when Orie and Gordeau start to argue. At a safe distance, Weiss reveals her suspicions to Ruby about the tournament and they begin to worry about collecting the Keystones. Ultimately, Weiss decides that they should go ahead and find the last stone. When Ruby protests that something bad might happen, Weiss reminds her to believe in her teammates. They part ways with Ruby searching for the last Keystone and Weiss rounding up Blake and Yang.

In Chapter 6, Ruby finds the last Keystone in the hands of Yosuke and Yukiko. When she challenges them to a fight for the stone, she becomes excited when she mistakes them for a ninja and geisha. Upon remembering that she cannot fight alone, she is suddenly approached by Es, who offers her assistance.

In Chapter 7, Ruby collects the last Keystone but is later surprised when Es suddenly transports Yosuke and Yukiko away. She is further shocked when Es turns on her and demands the Keystones without giving a reason why. When Ragna suddenly appears and reveals that Es and Rachel are both hiding something about the Phantom Field, Ruby shares with him about the vampire's instructions to go to her with all of the stones with no information about the world and the tournament they are in. She is later surprised when Ragna makes himself her tag partner in order to battle Es and get the information they need from her. Ruby tries once more to just talk with Es but to no avail, prompting her to team up with Ragna. A Seithr clone of Ruby is made by Es to even the battlefield.

In Chapter 8, Ruby and Ragna demand answers from a defeated Es, who reveals that the Keystones are the core of the Phantom Field and that Rachel is the only one who can seal away the stones so that the world will collapse and return everyone to their worlds. Ruby then urges everyone to start searching for Rachel but is stopped by Hazama, who has become suspicious of the System XX who has been guiding Ruby. They all learn that the System XX has been gathering battle data thanks to Ruby holding the Keystone, and now plans to use the Huntress as a catalyst to shift the Phantom Field into the world of Remnant. Ruby is then attacked by the System XX but is protected by Ragna who takes the blow for her. As the Keystone reveals its true form, the Huntress confirms with Es that the only way for everyone to return to their worlds is to now defeat the stone. With both Ragna and Es too injured to fight and Hazama suddenly missing, Ruby worries about fighting the Keystone on her own when her teammates suddenly arrive. With her friends now by her side, her confidence is restored and she decides to take down the Keystone together with her team. Worried about Ragna and Es, Ruby directs Blake and Yang to protect them while she and Weiss fight the Keystone. Upon learning that Ragna protected Ruby earlier, Yang thanks him for saving her younger sister. Ruby and Weiss then prepare themselves to battle the Keystone.

After Ruby and Weiss destroy the Keystone, Team RWBY revels in their victory and the hope of returning home. When Hazama suddenly reappears, Ruby receives the red Keystone from him as everyone is returned to their respected worlds. She then wakes up in Team RWBY's dorm room and finds the Keystone in her hand, causing her to panic and searching for a way to dispose of it. Her teammates then enter the room and are shocked to find her in possession of the Keystone. The stone fervently apologizes to the team for its actions and assures them that it can now only maintain its physical form. Ultimately, Team RWBY decides to keep the stone to keep an eye on it and prevent it from doing anything suspicious. Ruby then gives a cheer for the team to fight for justice and to save people, to which they all happily agree.

Cooperative Ending


In Chapter 2, after Ruby and Blake lose to Ragna and Gordeau, they listen to the Grim Reaper's suspicions about the tournament and his conclusion that they might not even have to compete for the Keystones and that they should stop fighting each other. While Blake is unsure of Ragna's assumptions due to the lack of evidence, Ruby believes him and allows him to handle the stones, much to Blake and Gordeau's surprise. Ruby shares with Blake her belief that there is a chance that risking their lives for the Keystones will be pointless in the end, and she wants to fight for something that she is absolutely sure of. Ruby then asks Ragna to keep his Keystone safe before she and Blake take their leave.

In Chapter 9, Ruby and Weiss appear in the final stage with several fighters from the other three worlds. The Keystones then disappear from their possessions as the System XX reveals its final form. After Rachel reveals the nature of the System XX and concludes that the only way to stop it is to destroy it, Ruby, Weiss and everyone else rallies Ragna to fight, despite the uncertainty of whether or not they will make it back to their worlds. Ruby then teams up with Ragna, Yu and Hyde and they destroy the Keystone together. Afterward, they all return to their original worlds.

 * Team RWBY's Distortion Drives are based on moves that the characters use in the show:
 * Ruby's first Distortion Drive, Petal Burst, references a move that she has used several times where she spins while using her Semblance, wrapping herself in her cape. The second, Petal Dance, refers to a combo she uses against the Beowolves in the "Red Trailer".
 * Team RWBY's Astral Finishes are also based on moves that the characters use in the show:
 * Ruby's Red Reaper - Ruby pulls her opponent into the air with her Semblance, hooks Crescent Rose onto them, and utilizes the recoil of her gunshots to keep up her momentum, before finally slicing through her opponent. This is similar to the move she uses to decapitate a Nevermore in "Players and Pieces".
 * Weiss' White Night - Weiss uses Myrtenaster to fire cyan laser-like projectiles, which she has done more than once in the show. She then leaps into the air and uses the same pose and motion that she performs at the end of her battle in the "White" Trailer while summoning and launching her Arma Gigas' sword.
 * Blake's Black Death - The first half uses the same moves that Blake performs when she first attacks a Nevermore in "Players and Pieces", including the use of her Semblance for mobility. The second half uses the same spinning attack that she performs against the Spider Droid in the "Black" Trailer, followed by her opponent disintegrating similarly to how the Spider Droid does upon being defeated by Adam.
 * Yang's Yellow Dragon - Yang activates her Semblance with flames bursting around her and then slams her heel down on her opponent before unleashing a flurry of punches on them. She finishes off her punching spree by uppercutting her opponent into the air. She then leaps up higher than her opponent and brings them down with her while she delivers a fiery, explosive punch to the ground below, incinerating her opponent by using a similar pose and motion to the move that she begins her battle with in the "Yellow" Trailer. When her fist strikes the ground, large shards of glass burst into the air, referencing the glass dance floor in Junior Xiong's nightclub, where the "Yellow" Trailer takes place.

BlazBlue: Cross Tag Battle Opening Animation

 * The scene with Ruby jumping in front of the moon and firing Crescent Rose in its gun form is taken from the "Red" Trailer where she does the same to a pack of Beowolf Grimm.
