(3rd Person POV)

Lazarus laid there on the snowy ground of his soul as his mother, Azealia, continued to repair his soul. He looked up into the sky, seeing less cracks in it and it was filled with snow clouds before he sighed.

Lazarus: Mom?

Azealia: Yes son?

Lazarus: How are you... still...

Azealia: Alive? Heh, well I guess I can't delay this story any longer.

Azealia continued on the repairs as she told her son the story on how she "survived".

Azealia: When that Minotaur Grimm attacked our home in Mantle, my first priority was to ensure your survival. After getting you out, I fended off the Minotaur for as long as I could but I knew, even if I was to kill it, I wouldn't survive. You remember how I died right?

Lazarus: *nods* How could I forget it? You were slammed against that concrete before it impaled you with its horns. And after that, you managed to behead the Minotaur with one of your scythes, killing it

Azealia: Yeah. At that point, I thought I was done for... But, I found myself... in a space of some sorts... I can't really describe it, but he was in there...

Lazarus: He...?

Azealia: The Alpha Guardian Beast, Godzilla.

Lazarus: Godzilla...? Alpha Guardian Beast...? Wait... do you mean that the Mysterious Fifth Guardian Beast that asserted dominance over all of them, was Godzilla??

Azealia: That's right. And his blood runs through mine veins... and yours.

That fully caught Lazarus' attention...

Lazarus: W... What...? So are you saying...?

Azealia: Yes my dear son. Your teammates aren't the only Hybrids at Beacon. You're one as well. You're their Alpha, their King. And the only reason I'm able to be with you in spirit now, is because of how powerful Godzilla's blood is. He, in simpler terms, connected our souls, allowing me to resign within your soul, guiding you.

"MURASAME!"
CHAPTER 4: SIBLING RIVALRY

(3rd Person POV)

In the Amity Colosseum, Weiss and Yang made their ways towards the center of the arena. Weiss looked up to the stands to see her teammates, Cassie, Cassandra and Olympia cheering her, but she downcasts, remembering that Lazarus wasn't there... but then she gained a look of determination.

Weiss' thoughts: I'll win for you, Laz.

Yang: Well, now it's our turn.

Weiss: Just remember to keep proper form.

Yang: Alright, you're from Atlas. What could we expect?

Weiss: Well, seeing as their Kingdom, Academy and Armed Forces are all merged as one, I think we can expect strict, militant fighters with advanced technology and carefully rehearsed strategies.

As soon as she said that, a rainbow flew past them. Neon Katt, a pigtailed Faunus with a cat tail and roller blades, Flynt Coal, wearing a fedora and shades, holding a trumpet arrived in the arena; their team was Team FNKI Weiss and Yang, for the lack of a better term, were shocked and confused.

Weiss: ...Or whatever they are...

Flynt: Hey! You're Weiss Schnee right? The heiress.

Weiss: I am.

Flynt: I take it you're pretty good with Dust then?

Weiss: I do my best.

Flynt: Yeah, my dad was good too; owned a little Dust shop of his own... Till your father's company ran him out of business.

Weiss looked down in shame.

Weiss: Oh... I'm sorry to hear that.

Flynt: Hmph, sure you are.

Yang: Hey! Why don't you-

Neon: "Hey! Why don't you!" That's what you sound like!

Yang: Uh...

Neon: Hey! Where'd you get your hair extensions?

Yang: This is just my normal hair.

Neon: Ooh Really?

Yang: Yeah! Is that a prob-

Neon: You should try rollerblading sometime! It's super fun! It'd probably take you a while though since you're so... you know, 'top heavy'

Cassie: Oh no...

Yang looked down on herself before looking back at Neon, agitated.

Yang: Excuse me!?

Ruby: Oh here we go...

Cassie looked over at Cassandra, only to see her gritting her teeth and growling at the cat Faunus in the arena.

The combatants ready themselves as the Aura levels appeared on the screen and the four biomes rose up; the Geyser, Lava, Ice and Urban biomes, though Weiss and Yang seemed, unsure about this.

Port: 3... 2... 1... BEGIN!   

Immediately, Flynt blew into his trumpet, creating a column of sound waves towards Weiss and Yang, which was strong enough to knock them both back as Neon began to skate around them, leaving a trail of rainbows behind her. Weiss uses her Gravity Glyphs to stop herself as Neon separated Yang from Weiss. As Yang chased Neon around, Weiss continued to make more Gravity Glyphs in front of her, to slowly make her way towards Flynt through the sound waves but he suddenly stopped blowing his trumpet, knocking Weiss a bit off balance but she charged him with Myrtenaster, using a white Glyph to propel herself but Flynt side stepped out of her way and kicked her into a orange crystal in the lava biome, shattering it completely.

Yang continued to chase after Neon into the city biome, firing off shots from her Ember Celica but Neon simply and smoothly dodged all of her shots while rollerblading around. Neon even blew a raspberry at Yang, annoying her further.

Neon: Never miss a beat Never miss a beat. Never miss a beat Never miss a beat.

Neon then charged at Yang, smacking her around while basically dancing around her, making her more angry before she smirked and cracked her nunchucks, causing them to glow a bright sky blue. Then she skated over to Yang and hit her leg with her nunchucks, incasing it in ice.

Neon: Look, now your bottom heavy too!

Yang gritted her teeth before stomping her foot, shattering the ice but unfortunately for her, Neon zipped over to her and froze her left arm before knocking her into a broken wall from the city biome.

Cassandra's thoughts: Yang I swear to god you better rip her god damn tail off!

Neon: You should cool off... Get it? Cause you're angry.

Now even more pissed, Yang smashed her hand against the wall, shattering both it and the ice.

Back with Weiss, she was twirling around with her Myrtenaster, gracefully creating four Ice Glyphs behind her that sent out large chunks of ice towards Flynt. He seemed slightly surprised before smirking as in idea came up in his head. He back flipped and landed on his knees as lava sprouted out from hole in the Lava Biome before blowing his trumpet into it, sending sound waves coated in flame towards the ice, melting them.

Flynt: Too bad all that money can't buy you skill.

Weiss seemed slightly annoyed at Flynt's comment before the chamber in Myrtenaster spun into the Wind Dust Chamber. Weiss pointed Myrtenaster at Flynt as he blew into his trumpet again but Weiss did a smart thing and countered it by launching a small tornado from Myrtenaster which cancelled out Flynt's sound waves with neither overpowering the other. As this happened, Weiss began making gestures with her other hand as White Glyphs appeared all around Flynt. Weiss then quickly jumped from Glyph to Glyph, striking Flynt who had no way to counter... well until suddenly, three more projections of himself appeared and all began blowing their trumpets which knocked Weiss completely out of her Glyph circle.

Port: What's this?

Oobleck: It appears young Flynt has just activated his Semblance! And quite a remarkable one at that. Ladies and Gentlemen, feast your eyes on Flynt Coal's, Killer Quartet!

While Flynt deactivated his Semblance, Yang was still getting more and more frustrated with Neon who kept taunting her; her eyes even began to turn red.

Neon: Ooh! Flashy eyes! Ya'know. You're actually kind of pretty when you're angry.

Yang's eyes flicker back to their purple color.

Yang: Shut up, shut up, SHUT UP!

Yang chased Neon as Weiss struggled to get back up. She tried reaching for Myrtenaster but Flynt put his foot on it, keeping it down as he smirked at her. Then they both turned their heads to see Neon still taunting Yang as she slowly rollerbladed in circles around her.

Yang: Get back here!

Neon: I wasn't trying to say that you should go on a diet, I was saying you REALLY need to go on a diet!

Yang: THAT'S IT!!!

Neon: You're fat!

At this rate, Cassandra from the stands tried to go down there but Cassie and Blake held her back.

Cassie: Calm down Cassandra!

Flynt smirked back at Weiss before turning his attention to Yang who was trying to cool down and aimed his trumpet at her as he activated Killer Quartet. Weiss saw this but then looked back at a Geyser in the Lava Biome so she did the crazy. Using the last of her strength, she got up and tackled Flynt from behind, sending them both falling onto the Geyser as it gushed lava from it, engulfing both of them and leaving everyone, in shock.

Yang: What?

Ruby, Blake, Cassie and Olympia: WEISS!!!

Cassandra: *shocked Pikachu face*

Maina: That girl got guts...

Miana: I hope she's okay...

Port: It appears we have a double knock out on our hands!

Oobleck: In fact, it looks as though Ms. Schnee's Aura has been completely depleted! She sacrificed herself to take out Flynt! Wait a minute... What's this!?

As the steam disappeared, Flynt came out stumbling.

Port: Ladies and Gentlemen, Flynt Coal remains standing!

Neon: You did it Flynt! Don't worry about her, she's easy! But kind of annoying.

Yang seemed to have finally reached her breaking point as she clenched her fists tightly and the ground rumbled.

Port: Ooh, look like Yang's angry! And you wouldn't like her when she's... upset.

She yelled in rage as her eyes turned red and her hair glowed golden with flames and multiple lava geysers erupted behind her. She immediately began firing shots from Ember Celica towards the duo of Atlas.

Flynt: Yo Neon go!

Neon charged Yang as Flynt began blowing his trumpet at her, knocking her away but Yang used the recoil from Ember Celica to move forwards. Neon entered the tunnel of sound waves as she and Yang began to duke it one. Yang launched herself into the air and shot multiple round to the ground, causing pieces of it to shatter. Neon moved over to the Geyser Biome but began to struggle over there. As Yang free-fall, Flynt activated his Killer Quartet and fired off sound waves towards Yang in an attempt to blow her out of the stage but Yang had a plan. She continuously used Ember Celica's recoil to brute force right through the sound waves and clasp the end of Flynt's trumpet, sending the sound waves back at him depleting his breaking his Aura.

Oobleck: Oh! Sour note for Flynt!

Cassandra's thoughts: Yes! YES!!! DO IT! CRUSH THEM BLONDIE!!!

Neon continued to struggle to maneuver the rocky Geyser Biome but she began chanting to herself.

Neon: Never miss a beat, never miss a beat. Never miss a-

Unfortunately for her, her rollerblades got caught in a crack, causing her to trip

Neon: Beat!?

As a tear flowed out of her eye, she began to tumble down the hill and into a gushing Geyser, sending her flying into the air. Yang saw this and decided to do some target practice. Aiming one of her Ember Celica, she fired a shot at Neon who was still in the air. It made contact and caused her to explode, draining her Aura all the way and giving Yang the victory. The crowd began to cheer as Ruby, Blake, Cassie, Cassandra and Olympia began to quickly sprint over to them. Yang seemed to have remembered Weiss too as her eyes changed back into iliac.

Yang: Weiss!

Yang ran over to the now soot-covered Schnee. She kneeled down to her and held her up.

Yang: Weiss! Weiss! Are you okay!?

Weiss slowly regained conscious and began coughing.

Weiss: I... may not be singing for a while...

Yang: *smiles* You know, I don't think that was proper form.

Weiss: Oh ha. Ha! *coughs*

Neon: WHAT!?

They looked over to see Neon shocked beyond belief and even her color was drained as Flynt slowly stood up.

Neon: We lost!? We lost!? Team FNKI lost!? That was... That was... AMAZING! *her color magically comes back* Oh my gosh, you guys were super crazy awesome! We should definitely party together sometime, right Flynt?

Flynt: That was a gutsy move Schnee... I dig it.

They smiled at them as Ruby, Cassie, Blake, Olympia and Cassandra came to their side.

Blake: Good job you two!

Ruby: Yeah!

Yang: Aww thanks guys!

Cassandra immediately lunged into Yang, tackling her into a big hug.

Cassandra telepathically: Awesome going, Blondie! I'm so proud of you!

Yang blushed but giggled and hugged her back.

Yang: Thanks Sandy.

Cassie kneeled next to Weiss.

Cassie: Laz would be proud of you.

Olympia: That's right! You were super duper awesome! There's no way Laz wouldn't be proud!

Weiss looked at them before smiling sweetly.

Weiss: Yeah... You're right.

Port: Alright! It's time for the final Doubles Match!

The randomizer on the screen began to role before landing on...

Port: Cassie Ghidra and Cassandra Ryuseicho of Beacon!

Then the second pair landed on a familiar face to Cassie.

Cassie: Oh you've gotta be kidding me...

Port: Against Ichigo Ghidra and Keqing Qixing of Haven!

Yang playfully elbowed Cassandra.

Yang: Well would you look at that. Wreck em' up girls.

Yang bent down to Cassandra's level, before surprising her with a peck on her cheek, causing her face to be overcome by a massive wave of blush.

Ruby: We'll be rooting for you two!

Olympia: Do it for our chief!

Weiss: Good luck

As Yang picked up Weiss, Blake noticed Cassie's nervousness and walked over to her, concerned.

Blake: Cassie, are you okay?

Cassie: H-Huh? W-Well... You heard who our opponents are...

Ruby: What? It's Keqing Qixing and Ichigo Ghidraaaaaaa.........

*awkward silence*

Everyone: YOUR BROTHER'S HERE!?

Cassie sighed with an embarrassed flush of blush on her face.

Cassie: Y-Yeah... My big brother...

Then, much to Cassie's dismay...

???: Yo, baby sis!

Cassie jumped upon hearing the voice calling out to her. Everyone turned around, only to see the other two combatants, a male with, just like Cassie, Purple short hair, red eyes and he had twin golden tails; Cassie's elder brother, Ichigo Ghidra.

And his partner, a young female also with purple hair but at a much lighter shade, in the odango twin long pigtails hair style, with bright magenta eyes that gave off a look of authority; this was Keqing Qixing.

Cassie: *painfully* Ooohhh.... Hi dear brother...!!! *in thoughts* Why THE FUCK did it have to be you!? I have no chance on winning now!

Yang: Uh... We'll leave you four, alone.

Ruby: Good luck!

As they began to walk away, Blake turned to Cassie before grabbing her by the arms and pulling her towards her.

Cassie: B-Blake???

Blake: This is for good luck.

Immediately, there were some whistles in the crowd as Blake smashed her lips against Cassie's causing her face to turn a shade of red that would put Pyrrha's hair to shame but she melted into it and returned it. They separated as Blake winked at her before running off.

Ichigo: Damn, will you look at that. My baby sis has finally grown up.

A cartoonish tick of anger popped up on Cassie' head as she and Cassandra turned to face the duo.

Cassie: You know... I would usually say that I'm happy to see you, dear brother... but for some reason, I can't today.

The biomes began their randomization progress as Keqing reached for her Raiju and Akuma, which were holstered on her hip before unsheathing her katana, Raiju from Akuma, the sheath.

(I don't own them obviously. Just change the blue to purple.)

Keqing: Would you two stop procrastinating already?

Ichigo: Aww, c'mon Kekw- OOF!

Immediately, Keqing wacked Ichigo on the back of his head with a massive blush on her face.

Keqing: I told you NOT to call me that, Baka!

Cassandra telepathically: Did she seriously say the word...?

Cassie: I think she just did... Anyways, Cassandra, leave my brother to me...

Cassandra telepathically: Got it. I'll handle the Tsundere wannabe cat girl.

Just then, the biome randomization selection was over, revealing the four biomes to be Ocean, Ice, Forest and Savanna biomes. Cassie and Cassandra equipped their respective weapons as Ichigo equipped two golden dragon neck whips, like Cassie's Ni and San; their names were Yon and Go.

Ichigo: Just don't expect me to go easy on you, sister!

Cassie: *scoffs* Like you could ever!

Ichigo: Oh, someone's confident? Well let's see where that confidence takes you!

Port: 3... 2... 1... BEGIN!

Immediately, the two Ghidra siblings activated their shared Semblances of Ghidorah's Spark before blinking away into the air, trading strikes with one another causing the sky to spark with golden electricity.

Port: Oh! What a sparking way to kick off the final match!

Cassandra looked up to see the battle of speed happening before a purple diamond object suddenly appeared next to her. She backed away in confusing before Keqing suddenly appeared in front of her in a blink of an eye, before swinging her sword at her. Fortunately, Cassandra managed to narrowly dodge it before retaliating with a strike of her own, only for Keqing to suddenly blink away.

Cassandra's thoughts: So she's the speed type...

Keqing: Incoming!

Cassandra's thoughts: Eh!?

She looked back up, only to see another Purple Lightning Stiletto, in her face before Keqing blinked to it, doing a horizontal strike which Cassandra managed to back flip over before rushing up to her opponent. The two traded strikes with their blades before, Keqing back-stepped out of the way and sent an horizontal arc of violet lightning towards Cassandra, who jumped out of the way before firing off her >Sonic Scalpel< at her, but Keqing redirected the shots with her Raiju before bolting towards

Keqing: Heh, not bad!

From the stands, Team RWBY, JNPR, Olympia, Miana and Mania watched the battle with amazed expressions.

Yang: Come on Cassandra! Put some muscle into it!

Ren: They seem pretty evenly matched.

Ruby: How is that Keqing girl so fast!?

Olympia: The Qixing are quite well known actually, especially Mistral. They became "famous" for personally assisting the Faunus, more specifically the ones in Menagerie. In fact, they're the only humans allowed on Menagerie.

Jaune: Wait really?

Pyrrha: That's right and Keqing's the youngest daughter of the Qixing Family. You could say she's some kind of royalty like Olympia, Weiss and Cassie. I battled against her in the Mistral Region Tournament every year and I'll say this, she's nothing to scoff at. In fact, I can safely say that she could have easily beaten me.

Everyone looked at her in shock.

Yang: Wait, wait. You, THE Pyrrha Nikos, almost LOST to her!?

Pyrrha: Yeah. She managed to make her way up the tournament easily and gave me quite a run for my money. I could consider her a type of rival. She may seem a bit... cold to others, but she's a really caring person.

Blake: So how is she moving so fast?

Pyrrha: That's her Semblance which she called, Trulla Cementarii. With it, she can summon a Lightning Stiletto to blink towards it for quick strikes and so much more. She's quite fast. I wouldn't say she's as fast as some like Ruby or Cassie, but fast enough.

Nora: Ooohhh! What's with everyone and having Semblances related to lightning?? Am I just that awesome??

Ren: *facepalms* Nora...

Yang: Okay, this might actually be rough for them...

Back in the fight, Ichigo was knocked back into the Ice biome by Cassie, who knocked him back with Ni. When he came to a standstill, he noticed his sister blitzing towards him at lightning fast speeds. With a yell, he threw both Yon and Go at Cassie, who responded by throwing Ni and San. The four dragon head whips battled with each other as Cassie send an overhead lightning enhanced kick down on her brother, who blocked with his arms, sparking with golden lightning.

Ichigo: Heh, not bad sister. That one actually stung a little.

Cassie growled before kicking off her brother and throwing a lightning fast punch at her, which he managed to dodge, but only narrowly.

Ichigo: And your speed has increased significantly since the last time we sparred.

Cassie: Stop talking and fight!

She demanded before blitzing towards her brother, with Ni and San by her side. Yon and Go descended next to their owner. Ichigo just smirked.

Ichigo: As you wish!

Ichigo sent Yon and Go to cut off Ni and San as Cassie made it past them, bolting directly towards her brother, who just stood there with a smirk. With a yell, Cassie threw a lightning punch at her brother but he somehow caught it...

Cassie: W-What!?

Ichigo: Tsk, tsk, tsk. Dear sister, you're strong. But not strong enough.

He grasped her hand firmly before unleashing a burst of electricity, causing Cassie to scream in pain as she was sent flying back.

Blake: CASSIE!

Cassie's eyes clutched closed from the pain before they suddenly sprung open, revealing them to be glowing a brilliant golden color before...

"GHIDORAH!!!"

*ROAR!*

[There should be a GIF or video here. Update the app now to see it.]

With the call of her Guardian Beast, Cassie transformed into her Hybrid form, causing the crowd to go wild.

Oobleck: Would you look at that! Cassie's gotten serious now!

Ichigo stared at his sister with the biggest grin he's ever had.

Ichigo: THERE WE GO!

Keqing was using her lightning stilettos to blink across the savanna biome as Cassandra used her Semblance, Iris' Blink to go after her.

Cassandra's thoughts: Damnit! She's too fast! I need to get in close and deal a heavy strike!

Cassandra though as she sent one of her tentacles at Keqing, who spun around before kicking it away and blinking away to another lightning stilettos. Cassandra grunted in annoyance as she fired off her >Sonic Scalpel< at her, managing to knock her off balance, knocking her on her butt. Cassandra smiled, seeing that this was her chance but unfortunately for her, Keqing smirked slightly...

Keqing: You got lucky that time!

Cassandra's thoughts: E-EH!?

Suddenly, Keqing warped right behind Cassandra and kicked her in her back, causing her to stumble forwards, but immediately with a snarl, she turned around and slashed at Keqing, who flipped out of the way before transforming Raiju into its machine pistol form and firing it at the hybrid girl, who deflected all the bullets. When she finished however, Keqing was nowhere to be seen... Cassandra franticly looked around for her, only to see Keqing crashing down on her from above, knocking her back, flat.

Port: Oh! And Cassandra's Aura is dropping!

Yang: Hang on Cassandra!

Keqing began to approach the downed Hybrid girl, swing her Raiju around.

Keqing: I'll admit, you're a formidable opponent, though Pyrrha was stronger in many ways. But I will say you fought well. Now this is the end.

Cassandra gritted her teeth as she struggled to get back up.

Cassandra's thoughts: Damnit, DAMNIT! She was just toying with me!

Cassandra slowly looked up, only to see her friends cheering her on... But the one that overpowered all of them... was Yang.

Yang: COME ON CASSANDRA! DON'T GIVE UP! YOU'RE STRONGER THAN THAT!!

Cassandra's eyes widen from realization as she heard the faint roar of Iris in her mind. She looked down, before clenching her fists...

Cassandra's thoughts: Not yet... I'm not... done... YET! GIVE ME POWER!

"IRIS!!!"

*ROAR!*

[There should be a GIF or video here. Update the app now to see it.]

Port: And Cassandra is powering up to even the odds of this fight!

Keqing gained an expression of shock as she saw Cassandra rise in front of her with her Guardian Beast behind her before disappearing, completing her transformation.

Once her transformation was complete, Cassandra blinked behind Keqing, faster than she could see before striking her back with her Evil God's Spikes, coated in her >Overboost Plasma<, causing her to stumble a bit forwards. When Keqing turned around, she was only met by Cassandra firing off her >Sonic Scalpel< from all four of her tentacles at her. Keqing retaliated by reflecting all of the shots, but unfortunately for her, Cassandra was already one step ahead of her, lashing her four tentacles out at her. Keqing managed to dodge two of them but the other two managed to knock her back into a tree of the Forest Biome.

Keqing: *coughs* Damnit... That power up really is as strong as they say it is... But, it's not invincible!

Keqing glared at Cassandra, who was walking ominously towards her before firing off her >Sonic Scalpel< at her. However, Keqing summoned a lightning Stiletto next to Cassandra, before teleporting to it. Cassandra attempted to slash at her, but when she did, Keqing seemingly fazed out of existence, like a ghost of some sorts...

Cassandra's thoughts: W-What!?

Keqing: You have nowhere to hide! Starward Sword!

With Raiju's blade coated in violet electricity, Keqing unleashed the full power of her Semblance, bending into the shadow of her blade before striking a series of thunderclap-blows directly to Cassandra, causing her to scream in pain before, Keqing dealt one final horizontal slash, before sheathing her weapon, causing the final strike to violently shake Cassandra's Aura.

Cassandra's Aura continued to drop and drop as she slowly fell over, the faint voices of Yang and her friends calling out to her. But suddenly...

Cassandra's thought: No... NO!!!

Keqing's eyes widen from shock as Cassandra's tentacles wrapped around her arms and legs before pulling her in point blank range of her.

Keqing: W-What!?

Cassandra's thought: If I'm going down... THEN I'M TAKING YOU DOWN WITH ME!!!

Cassandra tightly held onto Keqing, who was struggling to escape her grasp as she began to glow an intense fiery red. Both Cassandra and Keqing's Auras began to flicker violently before the roar of Iris echoed throughout the entire arena, even gaining Cassie and Ichigo's attention.

. . .

"PLASMA AURA DETONATION!!!"

. . .

Cassandra's thoughts: It's up to you now, sis...

The arena rumbled violently as Cassandra and Keqing were engulfed in a brilliant explosion of fiery glory, causing shocked expressions in the crowd... When everything had calmed down, Cassandra and Keqing were both seemingly unconscious on the ground, with their Auras shimmering violently before finally shattering.

Yang: CASSANDRA!!!

All Cassie could do, was stare in absolute bewilderment...

Port: And both Cassandra Ryuseicho and Keqing Qixing have been eliminated from the match!

Oobleck: It seems like Ms. Ryuseicho used some form of self-detonating technique to eliminate both herself and Ms. Qixing from the match! What determination!

Cassie's thoughts: Cassandra... you used it...?

Oobleck: It's a one on one between the Ghidra Siblings!

Ichigo: Keqing... *looks at Cassie* You're teammate is powerful and determined, I'll give you that...

Cassie: *mumbling* Cassandra... If you didn't have your Aura, that would have killed you......

*Plasma Aura Detonation is a technique specific to anyone with the blood of Iris, such as Cassandra Ryuseicho. It overload's her Aura with her Overboost Plasma before eventually, it self-detonates, creating a large area of effect explosion that is Guaranteed to shatter any Aura of anyone in the range and is guaranteed to kill anyone without Aura. The downside however is it's a double edged sword as her own Aura will be destroyed in the process. Cassandra can even use this ability, even if her Aura is depleted completely, by overcharging the plasma in her blood. However, doing so has a high chance of killing her. It is meant to be a last resort ability.*

Cassie clenched her fists before turning to her brother with Yon and Go by his side.

Ichigo: Well... I suppose it's time we end this, wouldn't you agree sister?

Cassie exhaled before getting into a stance with Ni and San as her wings extended to their maximum wingspan.

Cassie: Yeah... Let's end this, brother.

Ichigo: But first, let's be on a more, even level.

Cassie looked confused before her eyes widened, upon seeing that her brother's eyes were shining a golden color and an electrical aura surging around him before...

"GHIDORAH!"

*ROAR!*

[There should be a GIF or video here. Update the app now to see it.]

Ghidorah, the same as Cassie's erupted from behind Ichigo, roaring into the sky before engulfing him in a bright golden light.

Port: Oh! What this!? What a surprise from Ichigo Ghidra!

Cassie shielded her eyes from the bright light before it finally died down. When she looked, she was shocked to see her brother in a new form. His hair was a golden color as his eyes remained their crimson color. He wore a golden armor with shoulder guards that are similarly in design to a head from Ghidorah himself. He wore a cape that resembled the wings of the three headed dragon and his twin tails flailed about.

Yon and Go roared as he gripped onto them before smirking and getting into a stance.

Ichigo: This is it sister! The next move, decides this match!

Before she could even respond, Ichigo blitzed right in front of her, catching her by surprise with a strike from his Go whip, knocking her back.

Cassie: Damn!

With an agitated growl, Cassie's eyes began to glow golden before her eyes, along with Ni and San unleashed >Gravity Beams< at Ichigo, who responded with doing the same thing. Only thing was, Ichigo's somehow managed to overpower hers, sending her flat onto the ice. Cassie quickly got back up, only to see her brother speeding towards her. Using her wings, she sped up into the air, unleashing lightning bolts from her wings to strike down on Ichigo, but it seemed they only made him stronger as he unleashed more >Gravity Beams< at her. Cassie managed to dodge only to yelp in pain from Yon and Go biting down on her wings, before pinning her to the ground. Then their necks began to glow as Cassie's Aura began to flicker frequently.

Port: Oh and Ms. Ghidra's Aura is dropping FAST!

Cassie: A-Ah... W-What the...?? Ah...

Ichigo: Their draining your Aura. Who knows, maybe your Ni and San have the same abilities. There's nothing you can do to stop it.

Cassie grunted and attempted to at least sit up but Yon and Go wouldn't allow her. Even Ni and San weren't able to get up, due to their energy being connected to Cassie's Aura. Cassie could see her brother folding his arms confidently as it felt as if her life was being sapped away, even though it was her Aura.

Blake: CASSIE GET UP!!!

She could barely even make out Blake's voice as her conscience slowly slipped away... This was it... The end... She was defeated...

Cassie's thoughts: I knew it... Even after all of my training... I still can't come close to being strong like him... How...? How are you so powerful... big brother...?

Cassie sighed and closed her eyes, accepting defeat, until...

"It's not over, Cassie."

Cassie gasped upon hearing a voice that she didn't think she'd hear for a while...the voice of her beloved leader.

Cassie: L-Laz...?

"The spirit of the Thousand-Year-Old Dragon, has the strongest bond with you. Ghidorah's is calling for you, to transcend into greater heights. So rise, Cassie Ghidra and become the True God of the Sky."

Cassie's thoughts: ...The True God of the Sky...

On the screen, Cassie's Aura was just about to drop into the red zone before the arena began to rumble...

Oobleck: Wait a minute! Is this what I think it is!?

Ichigo: What!?

Yon and Go began to struggle before being forced off of Cassie as she erupted in a pillar of violet electrical energy...

Ruby: What's happening!?

Blake: I... I don't know!

Olympia: Cassie!

From within the energy pillar, the silhouette of Cassie rose up, changing ever so slightly, but every change made the difference...

*ROAR!*

[There should be a GIF or video here. Update the app now to see it.]

[There should be a GIF or video here. Update the app now to see it.]

(Play Song)

A massive three headed beast, similar to King Ghidorah erupted from the ground behind her, but something was... different... Instead of being composed of golden scales, its skin was primarily white and instead of two tails, it had three... It's left and right head have small golden horns while the center head possessed two large golden horns that almost looked like some form of head-crest.

But that wasn't the only difference... As the new "Ghidorah" roared into the sky before disappearing in violet particles, Cassie's figure could be seen in the epicenter of the massive ultra violet beam. For one, her hair had grown significantly longer and had reverted back to its purple color, a crimson scabbard materialized on her left hip... And most noticeably, her outfit was... well...

"MURASAME!"

A type of lightning bolt emblem appeared on her chest as something began to slowly rise up from it. A red hit, with some form of kanji written on it became more and more visible as the katana rose from the emblem on her chest, before Cassie reached for it with her right hand and pulled it out as her eyes shot open, revealing them to be a violet color instead of the normal crimson or golden colors. The blade of the katana surged in violet electrical energy as everyone stared in absolute shock.

Port: What is this!? I never seen this before in my life!

Ichigo also seemed shocked but had no time to react, as Cassie in her new form, suddenly appeared right behind him.

Ichigo: ...W-What...?

Her aura disappeared as she seeming stood there, doing nothing before she sheathed her katana, and tapped the hilt with her pinky.

Cassie: Eliminate.

All of a sudden, a series of thunderclap slashes surrounded Ichigo, striking him from every angle before immediately shattering his Aura, taking him out of his Hybrid form and sending him to the ground. The crowd began to cheer loudly from the show of sheer power, Cassie displayed to them.

Port: And Cassie Ghidra is the winner!

Cassie sighed before her katana, known as Murasame disappeared and she reverted back to her normal state, before she gasped, remembering...

Cassie: Cassandra!

She quickly ran over to the unconscious Iris Hybrid, sliding onto her knees before taking her into her arms. She dawned a worried expression as she checked for a pulse, but released a relieved sigh upon realizing that there was one. Cassie gently caressed the long and now messy red hair of her "sister".

Cassie: You dummy... You gave me such a scare... But, you were awesome out there... Sis...

Cassandra unconsciously let loose a smile as Ichigo, who was still on the ground, watched the interaction, just as Team RWBY and Olympia ran down to meet with their friends...

Ichigo: Cassie... You were always reckless in battle and I always had to come and save you... Heck, our parents would do their best to control your life just to "protect" you. But... judging from your display in combat today, you've proven, not only to me, but to the world that you're determination is unbreakable.

He weakly let loose a smile that seemed genuine and proud...

Ichigo: You're definitely my little sister... and that little sister, I'm very proud of...
