NASCA!
Cinder became the Nasca Dopant and charge of the two sisters, Ruby Rose aka Kamen Rider Zero-One, and Yang Xiao Long aka Kamen Rider Cross-Z.
"I'm going to make sure non of interfere ever again!" Cinder snarled.
"Yeah, that's not going to happen," Yang said as she blocked a punch.
"We're going to stop you and have you face justice for Pyhrra's murder!" Ruby added as she blocks an attack and kicks Cinder back.
*TAP! TAP! TAP!*
Footsteps. Footsteps are what they heard.
Everyone turned to see someone walking towards them.
It was an older man probably in his mid to late 30s. He was blonde, with a bit of a scruffy-looking appearance. What caught their eye was a Driver on his waist. Nobody knew who he was, well at least two girls did.
"Dad?!" Yang and Ruby look at their father in confusion.
"Wait, this is your father?" Weiss asked.
"We… we should leave…" Blake looked weary of the man. He was giving off this dark and evil aura that made her want to run away.
Raven could only look at her former lover with wide eyes as she spotted on what was his waist, the Vail Driver.
'He can't be back! He's supposed to be gone!' Raven thought
"What?"
Taiyang stopped in front of Cinder as well as the two other Riders he was in front of. The older man held up a strange-looking stamp with a red rhinoceros beetle on it before activating it.
KABUTO!
Tai stamps the pad on top of his driver before stamping the screen of his belt.
DEAL!
Tai raises his right hand before he slowly places it on his heart.
"Henshin."
Dark energy came out of the Driver, forming a rhinoceros beetle and a shadowy mass, respectively, with the latter engulfing both the beetle and Taiga.
BANE UP! HAKAI! (BREAK) SEKAI! (BROKE) KIKIKAIKAI! (BROKEN) KAMEN! (RIDER) VAIL!
The mass disperses, and yellow eyes glow and reveal Tai's Rider form, with the horn on his head raising, to complete the transformation.
Everyone was in shock to see this. Why was Taiyang doing this? How was he able to become a Kamen Rider? For Ruby and Yang, how much did they not know about their father?
Taiyang wore a grey jumpsuit with silver boots, gloves, and gauntlets. He wore a silver chest piece on his torso. He had a silver smooth shoulder guard on his left side while the right side had bronze armor that had a tube connecting to the suit front and back making it look like a beetle on his shoulder. He had a clear cape on the right side of his arm with a design of a beetle's wing. His helmet was silver with yellow compound eyes, the helmet had a silver tube from the right side of his helmet connecting to a bronze valve which was part of a bronze kabuto horn on the left side of the helmet. He is Kamen Rider Vail.

Elsewhere, in the Land of Darkness, Salem, the dark witch, and mother of the Grimm sense the dark energy as well.
"Hmm?" Salem turned to the direction of the energy she felt. "So he has returned." She gave a small chuckle. "What is your plan, Vail?"

Back with the young Hunters, they were shocked by Taiyang's transformation to a Kamen Rider.
"Dad?" Yang looked at her father shocked.
"That's… That's… SO COOL!" Ruby looked at her father with amazement.
"Your father? Then let him pay the consequences for interfering with me!"
Cinder charged towards Tai with her sword ready to slash him.
Before his daughters could protect their father, the latter held out his as red energy wrap around Cinder.
Cinder struggled to break free before being harshly tossed to the side, with full force she crash into a wall undoing her transformation.
Cinder groans as the others watched Vail's power.
"Woah…" That was all Yang could say.
As cool as her dad look right now… Ruby couldn't feel a chill appearing out of nowhere, it feels like she remember this dark aura from before.
The two Beowolves growled before they both charged at him. Beowolf 1 tried to slice Vail with its claw but the latter dodge the attack. Beowolf 2 tried to slice the Rider as well but the latter block the attack before pushing it away. Beowolf 1 tried to claw him once more but Vail hailed out his arm blocking the attack.
That block released dark red energy making the Beowolf 1 flip and land on its stomach, he then held out his left leg with his boot inches away from Beowolf 2 but it was pushed back by the dark red energy that came out of his boot.
Vail then grabbed hold of Beowolf 1 skull-like mask and held a firm grip on it. The latter tried to claw the former's hand on letting it go but to no anvil as Vail raised the Grimm up. Vail let out dark energy as Beowolf 1's body let out red electricity before exploding into dark ash.
Vail moved his head to the left before grabbing its right claw and kicking the Grimm to a wall while still holding his Beowolf 2's lower arm.
Vail started walking towards the last Beowolf who looked startled because in every blink of an eye, he vanish before repairing it a second later… it was scary.
He activated the Vistamp.
KABUTO!
He then stamps the Vistamp onto the screen.
CHARGE!
He confronted the stuck Grimm.
VAILING IMPACT!
With the Beowolf against a wall, Vail performs a punching motion, creating a red shockwave that crushes the Grimm.
He then performs a series of punching motions so fast that his arm leaves afterimages, with each punch creating another shockwave. After a brief pause, Vail delivers a final punch to the Beowolf directly, creating a large red shockwave that expands outward from the monster before it explodes.
Vail then turns to the girls before walking toward them.
"Dad?"
Vail then gave an energy kick at Yang making her fly a few feet away from the two making her de-henshin, he then grabbed Ruby by the neck.
"D-Dad, w-wha-at are you…" Ruby choke.
"It seems you've grown stronger little rose," Vail commented.
Under her helmet, Ruby's eyes widen when she heard that voice and that line before she could do or say anything her father let go of her neck and clutch his head.
"That's enough. Vail… leave my girls alone!" Tai said before he de-henshin.
Tai fell to the floor, groaning.
"Dad!" Both Ruby and Yang rang to their dad's side.
"Hmmm… where am I?" He asked before passing out.
"Dad!" The girls cried out.
"I can't believe he's back." The sisters look up to see Raven hovering over them.
"Raven? What do want?" Yang looks hostel but is protective of her family.
"Something I thought I would never see again," Raven replied.
Raven crouches down and grabs hold of Tai before lifting him up.
"Hey, what are you doing?!" Yang questions her.
"Taking him somewhere safe," Raven answered.
Raven opens a portal before entering it with Vernal following her.
"Hey wait!" Yang called out but the portal closed in front of her. "Damnit she left with dad, Ruby!"
Yang looks at her little sister.
"Ruby?"
The team leader looks up to her older sister.
"Yang… I think this is not the first time this has happened."
AN: I was going to make Weiss' grandfather into Destream during the Ice Queendom like Vail is inside Weiss but also a portion of her grandfather's soul and they fight and stuff but I went with this. Also, yes Ruby and Yang are Kamen Riders it would've been weird if Tai was the only one who was a Kamen Rider. I don't have a clue who Weiss and Blake could be, still thinking.
Have you guys seen Zein, can't believe he was Yuto Sakurai, they shred Ride Cards for the finishers, that's how I feel when I buy Toku toys. Also, Brain is coming back as a Humagear, now I'll be waiting for a Chase Humagear.
Also, I am now doing Super Sentai One-shots check my profile they're in a separate story so you'll won't see them here, I like to keep them separated. I got three chapters out.
