Setsuna: "You...!" 

Blake: "Mio..."  As the female black wolf Faunus was sat on top of a crate inside of the Train Car, with her legs swinging back and forth, she opened her amber eyes and looked towards them with an emotionless face.

Mio: "Long time no see, guys."

Akito: "Blake, Setsu. Go on ahead."  He said as he gripped Alpha tightly.

Blake: "Are you sure??"  She received no response from him as he simply stared at the second black wolf in front of them. Setsuna looked at Blake and nodded as she began to dash past Mio. Blake was about to run off but stopped and glanced back to him.  "Be careful..."

After she left, the two wolves were left in the car alone. With her swinging her legs for a final time, Mio hopped down onto the floor and faced him.

Akito: "Mio."

Mio: "Mhm. Long time no see... Big Brother."

A deafening silence filled the train car as the two wolves came to a standoff, the only audible sounds being of the battle taking place outside. With red and amber eyes locking into an intense stare, the atmosphere suddenly dropped to a tense one. The four sisters within Akito's head were... surprised as none of them even knew about this Mio person.

Autumn: "D-Did she just say, 'big brother'?"

Summer: "Bro..?"

Akito telepathically: *sigh* "Yeah. She's my younger sister.. She was around long before you four awakened inside of me, and by time you two did, she went on a mission to Atlas that Sienna sent her on. Sorry I didn't tell you girls."

Spring: "N-No, you don't gotta apologize, big bro. We're just shocked is all."

Winter: "Yeah... But that aside, I'm more concerned as to why she's standing against us..."

Mio: "You know..."  Her voice caught the attention of the five, whose attention was turned to her. Akito watched as she paced back and forth, her hands behind her back.  "Adam was unbelievably pissed when you left. When I got had gotten back from Atlas, he was still plotting ways to get back at you for 'betraying the Faunus'."  At this, Akito scoffed.

Akito: "'Betraying the Faunus'? So, me wanting to leave the White Fang is betraying them? Is he flat out stupid?"

Mio: "Believe me, I thought the same thing originally..."

Akito: "Then why haven't you left yet? You know for a fact that the White Fang isn't getting any positive results with all of this."

Mio: "... I can't leave, Big Brother..."  She closed her eyes with a sigh.  "I can't leave my family.. not after they've done so much for me.. I know.. I know that even underneath all of that darkness, there are souls that only wish for equality... I want to help them. Sienna, Ilia, Adam, all of them! They deserve happiness, and I will bring it to them. That is what my heart tells me."

The female firmly pumped her fist against her chest, right over her heart as she turned to face him, her amber eyes opened with determination and resolve.

Akito: "Mio..."

Mio: "Which is why... I will fight you today. Not to support Roman or this chaotic plan, but for myself. I need to prove to myself that I can do this... that I can help them. And I need to beat you first!"

With her grabbing onto the two white handles attached to her waist, she pulled on them, as two vigorous green energy blades erupted from the handle, becoming two Type 72 Beam Sabers. Mio took a stance with the dual Beam Sabers as her elder brother stared at her in silence, with him slowly clenching his fists.

Akito: "Mio... You're resolve is strong.. So I will grant you your request. But... I won't go easy on you just cause you're my sister."  With the large physical blade of Alpha flipping into position, Akito pointed it directly at the female wolf.  "If I beat you, leave the Fang. You can gain your objective without being a part of them. Look at what Blake, Setsuna and I have been doing."  He said as he pointed the physical GN Sword towards his sister, who was silent before she nodded.

Mio: "Alright... Deal."

>Chapter 19: Breach<

Arriving in the final train car before the locomotive, Blake and Setsuna come to a full stop, before gritting their teeth at the sight of Roman Torchwick, who was standing before them, his Melodic Cudgel in hand.

Roman: "Well if it isn't the kitty cat and the rabid dog. You two miss me? Where's the wolf with the supped up armor? Ah, never mind him. He's probably having a wonderful meeting with one of his old allies... You know, we really have to stop meeting like this, people are gonna talk..."  He said in a hushed tone.

Setsuna's response to that was to equip her Ice Wolf Claws. With a yell, she launched herself towards the ginger-head, who in returned let out an entertained hum and began to approach her slowly. As the she neared him, Setsuna leaped towards the man, who swung his cane weapon towards her. However, she instantly caught it between her teeth, catching the attack as she swung from it, using Melodic Cudgel like a monkey bar and landed on the man's shoulders, her legs wrapped around his head.

Roman: "Gah! Get off me you damn mutt!" 

He grunted and swung wildly to try and get her off, while Setsuna was too busy punching and clawing away at his head, ripping his hat from his skull before she used her body weight and bent backwards, carrying enough momentum to flip both her and Roman around. Using one hand, Setsuna landed safely on the floor, while the used her legs to fling the ginger-head straight at Blake. Seeing him coming, she quickly slid under him, while leaving behind a Fire Dust Clone that exploded in his face and knocked the man into the air.

Blake then leaped up to his level and dealt a three slashes before landing skillfully onto the ground, with the hatless man falling painfully onto his back. Now with both bladed parts of Gambol Shroud in her hands, Blake stood in front of Roman, while Setsuna was still behind him, one claw digging into the floor while the other was raised into the air as she took a primal stance.

A growl escaped Roman as he quickly used Melodic Cudgel's ranged form to launch two explosive shots at the two Faunus. While Setsuna simply swatted the shot coming her directing into the wall behind her, Blake stepped back, leaving behind a solid Earth Dust clone which crumbled upon taking the impact.

Now the two girls charged forwards together, with Blake making a leap towards him. Roman made a swing at her, but using her Semblance, she quickly created a clone in her place and now stood before him. With him surrounded, Roman did his best to fend off the flurry of slashes and claw attacks from the two girls, who weren't giving him any room to breathe. With Setsuna blocking a strong strike from the man's cane and skidding back towards the next door in the train car, he swiftly turned around to Blake, swinging Melodic Cudgel downwards. However, Blake quickly dodged back, leaving behind an Ice Dust Clone that caused his cane to get trapped in.

Roman grunted as the arctic wolf hopped off of his head, but his eyes soon widened as in front of him, Blake and a free-falling Setsuna, her eyes glowing bright blue from her Semblance, Primal Fury being activated, were preparing a final attack. While yelling, Blake swung her Gambol Shroud downwards, creating a large Aura Arc that quickly traveled toward the ginger man while Setsuna, quickly did a cross slash with her Claws, sending out multiple smaller Aura Arcs that combined with Blake's. In a matter of seconds, the attacks collided with Roman, sending him flying back into the wall painfully and onto his back.

With a cough and him holding onto his abdomen, he tried to stand up, but Setsuna, whose Semblance was deactivated for efficiency, quickly denied that request and pounced on him, the claw on her left hand deactivated as she used that one to hold the man up by his shirt, while the claw on her right hand, aimed for his neck. Blake soon joined her, glaring daggers at the man below them.

Roman: "H-Hehehe... *coughs* Why are we fighting?"  He looked towards Blake.  "I saw you at the Rally. We're on the same side and you know it."  In response, Setsuna only bashed his head against the metal floor, causing him to groan loudly in pain.

Setsuna: "Blake... will never join you, filthy human!"

Roman: "O-Oh... How touching.. She cares about you, haha.."  Blake didn't respond, only narrowing her eyes at the man. She was angry. This was her chance to finally make him get what he deserved.  "Oh, still feisty. Sooo, what are we gonna do now? You think a little bow on top is gonna make people forget who you were? What you've done?"

Setsuna was about to claw his eyes out, only for Blake to stop her and finally shut the ginger-head's trap, with a swift but powerful kick to the face, knocking him out.

Blake: "He talks too much..."

>Meanwhile<

Metal and beam collided against each other within a druid train car as sparks disintegrated onto the metal floor below. With a grunt, Mio slid across the ground and came to a halt, with her gripping onto her Beam Sabers before looking directly up to her opponent. Suspending in mid air, Akito, with him gripping onto Alpha, made a single overhead slash, sending out a rotating blade arc that looked like a buzz saw. Instantly, the female wolf Faunus retaliated, raising her two Beam Blades and blocking the attack, the two opposing forces of energy engaging in a heated battle that soon ended with Mio deflecting the attack into the wall.

With a slight gasp, Mio spotted her brother landing on the ground before dashing towards her, the GN Long Blade appearing in his off hand as he slashed the air a couple of times, sending out multiple Aura Arcs towards the female. Gritting her teeth, she avoided two before deflecting a couple. After the final arc flew past her head, Mio quickly sheathed her one of her Beam Sabers into its scabbard before pulling on it and converting it into a Type 72E4 Jinrai Beam Rifle.

Aiming towards the male wolf, she pulled the trigger and quickly began to fire off Green highly concentrated beams, however Akito simply reflected them with Alpha before quickly he reared his left hand back and launched the GN Long Blade towards the female, who gasped but before she could react, the blade made contact with her left hand, causing her to drop her Jinrai Beam Rifle. Now armed with one Beam Saber, Mio snapped her head back towards her brother, who was already in front of her.

The two trade blows at a speed that almost seemed too fast to normal humans, many sparks flying all over the place from each blade parried. Akito made a round-house kick towards her, causing her o block with her forearm and skid backwards, only to retaliate with a quick slash. Unfortunately for her, Akito already reacted and backflipped, his feet knocking the Beam Saber out of her hand. Gasping, she quickly picked it up and gave chase.

Landing back on his feet, Akito watched as she leaped towards him, Beam Saber held with both hands and over her head for a heavier slash, only for him to simply dash out of the way. After parrying attacks, he dashed away from one of her strikes before retaliating with a few thrusting attacks with his GN Sword, to which Mio narrowly dodged. Afterwards, they both swung their blades at each other and clashed, sparks flying off of the contact of blades.

Gritting her teeth, Mio felt herself being pushed back slightly before she intentionally released the pressure the was applying, causing herself to be pushed back, only to use her momentum to dodged out of the way of Akito's physical Alpha blade and retaliate with her Beam Saber, making an upwards slash that collided with his blade and sent his blade arm flying upwards, leaving him open.

Akito: "Tch..."  He grunted as her Beam Saber erupted in energy, her amber eyes glowing brightly.

Mio: "You're done!!" 

She was about to make a horizontal slash, only for her to gasp as she saw Akito's eyes glow bright red. He quickly dodged the strike and retaliated with multiple swift slashes himself, moving so fast that it seemed like he went invisible. Mio had a rough time blocking all of them but was too slow to dodge a final slash from the male, sending her crashing back into a wall with a thud and a grunt.

Just as she was standing up, her eyes widened as Akito was already dashing towards her, making a single slash as he passed by her, to which she gasped and glanced back at him, her Aura flickering before Akito was already behind her, folding Alpha's blade back onto the back of his arm as a series of slashes surrounded the female, striking her from every direction. With her Aura flickering violently from the attack, she fell forwards and onto the ground, with a loud thud.

Mio's thoughts: "He really isn't going easy... and he haven't even used his Semblance or Exia yet..."  She thought, struggling to stand she slowly looked back at him with gritted teeth.  "While... I haven't even landed a single strike on him... Am I really... that weak compared to my.. big brother...?"

Akito: "You lost, Mio."  She looked up at him, to see him pick up his GN Long Blade and made it dematerialize before he tossed her the Jinrai Beam Rifle she lost her grip on.

Mio: "B-Big Bro..."  She reached for her Jinrai Beam Rifle and holstered it and her Beam Saber onto her waist but soon, the exhaustion took over and she fell forwards, losing consciousness.

Akito stared at her unconscious form in silence... it has been a good minute since he's seen her and to think that this was their reunion; a battle. It didn't matter anymore. He won the fight and now, he'll take her back. As he was about to walk over to her, his eyes widened as busting through one of the doors was Weiss. Seeing the state the Ice Queen was in, Akito instantly managed to catch her in his arms, barely sliding back thanks to his heavier weight.

Winter: "Weiss!"  She managed to project her voice to the Heiress.

Weiss: "I-I'm fine.."  She groaned in response.

Summer: "Uh... Big Bro...? Ahead of you.."  Hearing her warning, he looked up as the sound of a revving Chainsaw could be heard loud and clear. He looked up to see the White Fang Lieutenant the Heiress was locked into battle with previously and gritted his teeth.

Akito: "Ah shit..."  He gently set Weiss back onto her feet and the both took a stance side by side, with the Lieutenant letting out menacing laughter, only for him to notice the unconscious Mio, causing him to gasp.

Lieutenant: "Miss Mio!"  He silenced his chainsaw and holstered it onto his back before crouching down to her. Upon feeling her steady heartbeat, he picked her up over his shoulder and glared at the two.  "Adam will have your heads for this!" 

And with that, he retreated with her. Akito was about to give chase, only for the doors behind him and Weiss to slide open quickly, revealing Blake and Setsuna. Immediately after however, Yang came dashing through the door Weiss broke through.

Setsuna: "Kito! Yang! Weiss! You guys are okay!"

Weiss: "Guys! Did you stop the train?"

Blake: "No. The breaks were shot. It's on a crash course!" 

Yang: "What!? Are they insane!?"  she exclaimed while Akito gritted his teeth in annoyance.

Akito: "Tch... C'mon, let's go meet up with Ruby."

Swiftly, the group of five made it back onto the roof of the roof and met up with the girl in red, who stood before them. Unfortunately for them, the train was quickly coming to a dead end.

Blake: "What do we do?"

Ruby and Weiss only shared a glance and a smirk before the heiress stabbed Myrtenaster down, using the Ice Dust to encase herself and the others completely in a crystal of ice.

Akito: "Everybody brace!" 

As they braced for impact, the train smashed right through the dead end, coming to an extremely harsh stop. While they were shielded from the debris, the impact itself sent them flying forwards through the hole created, landing on the concrete as the icicle they were entrapped in shattered, Pained groans came from all of the teenagers, their ears ringing as the sound of a distant disaster siren was heard going off. As Akito slowly got up, kneeling down on one knee, he took a look around to find that both himself and the girls ended up in the center of Vale, with civilians running away in a panic. He spotted Ruby, Weiss, Yang and Setsuna slowly getting up before he looked to Blake. He picked himself up and quickly went over to her and began to help her up.

Blake: *groans* "Thanks..."  She looked up at him and gave a faint smile, to which he returned with a nod.

Akito: "Everyone alive?"

Weiss: "Somehow..."

Yang: "Ugh... Looks like we really 'CRASHED' this party!"

S.S.A.W: "BOOOOO!"

Ruby: *groans* "Yang!"

Yang: "It was a good one!"

Setsuna: "It sucked and you know it."

Suddenly, the ground shook with a loud rumble. Everyone's heads turned to the hole the train crash created as a massive King Taijitu slithered out of it, followed by an army of Grimm ranging from Beowolves, to Deathstalkers to Ursai. The group of six were frozen in disbelief and horror before Ruby stood tall, her Crescent Rose in hand. Akito stood up too, Alpha in GN sword mode. Setsuna and Yang stood next to Ruby, their Ice Wolf Claws and Ember Celica respectively ready for action while Blake and Weiss took stance next to Akito, their Gambol Shroud and Myrtenaster respectively on the ready. A full army of Grimm surrounded them as the battle of the century was about to beginning.

Akito: "Ruby?"

Ruby: "Yeah. Let's do this, Team!"

Setsuna and WBY: "Yeah!"

Akito: "Gundam Exia, Akito Zara. Eliminating the Targets!"  He yelled, Exia's Gundam core glowing brightly as the entire armor formed around his body, the eyes glowing brightly.

Akito (Exia): "Wing Gundam Zero...!"

Jaune: "Woah..."

Ruby: "Who are they?" She asked as Maya landed on the ground, with her two teammates coming to her side.
