Sento raced down the stairs into the lab with a look of excitement on his face.
As he descended, he glanced down and saw Ryuga furiously doing push-ups.
"Hey, muscle brain!"
Ryuga frowned, pausing mid-pushup. He got to his feet and moved forward to meet Sento at the bottom of the stairs. "Who are you calling muscle brain!?"
Sento's hair popped into excited mode and his eyes sparkled. "I think I know where their base is!"
Ryuga halted mid angry stride at Sento's words and his face changed from pissed-off to a look of pure joy.
"Seriously!? Damn, man!"
Sento wiggled his eyebrows at Ryuga and walked past him, prompting Ryuga to spin around and follow closely behind.
At the top of the stairs, Sawa and Misora peeked through the entrance at the boys running off together into the lab with huge smiles on their faces.
Sawa grinned down at Misora, who was crouched right below her, "See? I told you they would work it out."
Misora's eyes lifted upwards to glance at Sawa while shrugging her shoulders and taking a bite of the spice covered pizza she had taken with her. "I feel stupid for worrying...cough cough!"
"Ohhh too spicy!"
Sento slid into a chair and flicked one of the computers on. It whirred to life and the monitor brightened.
A few programs were opened up and and several types of maps, images and energy signatures flooded the screen. Sento pointed to a spot and looked back at Ryuga while saying, "This Nebula Gas is coming out of the walls.
Ryuga stood behind Sento with arms crossed and squinted at the screen. "So that's what it was?"
Sento narrowed his eyes and scrunched his nose a little after hearing Ryuga speak. "You saw it?"
"Yeah."
Sento paused for a moment and explained briefly to Ryuga, "If you administer a concentrated dose of it, it encourages cellular division, turning people into monsters...That's what makes up the Smash essence."
Some dots connected in Ryuga's mind and his eyes opened wide. He spoke with slowly with the realization clear in his tone.
"So they gave me that gas... What about you?" Ryuga's mouth hung open in suspense as he looked over at Sento, waiting for an answer.
Sento stared at Ryuga with deep meaning in his eyes but didn't answer the question. Instead, he turned back to the screen, pointing at a certain point where there was a highly concentrated point of Nebula Gas leaking.
"Faust's base has to be under the area where the Nebula Gas is coming from."
Ryuga's mouth curled up in an unpleasant grin, "But that place has tons of security."
Sento pointed to another smaller signature on the screen. "But not this opening I found here, with gas flowing from it."
"I think that's a secure area." Sawa called out. Her and Misora were now also leaning over top of Sento and looking at the screen too.
Misora studied the rest of the spicy pizza in her hand and said, "Won't it be dangerous?"
Both of the boys looked at her with determination in their eyes, answering at the same time.
"We've gotta do it!"
...
Touto Government Offices - Prime Minister's Aide Office.
Gentoku walked into his luxurious office with his cell phone pressed to his ear.
It was a room full of dark brown wood with several high-end couches around a small coffee table, a modest yet dignified desk and a plush leather chair rested behind it.
Gentoku listened to the voice on the end asking questions while he looked at the rare antiques that lined one of the shelves on his wall.
"I've had him look at the data, as you ordered." There was a pause on the other end of the line and Gentoku finally had gotten a chance to respond.
"Seeing if Kiryu, Sento has what it takes to surpass you... "
Gentoku walked over to one of the couches and sat down while he talked. He lifted one leg and foot, resting it on the coffee table while getting comfortable. He grinned.
"...It should be interesting."
...
The next day.
Two men in matching tan colored coveralls walked through a park in a residential area that was right beside one of the numerous government Sky Wall checkpoints. They shared the weight of a large steel pipe on their shoulders, grunting with effort as they passed by several armed guards protecting the nearby gate fence leading towards the Sky Wall.
One of the workers nodded at a guard as they passed and said, "Hey." In a low voice with their helmet pulled low.
"Coming through..." The other worker piped up while looking away from the Guardian robot looking him over.
The fence the guards were in front of was connected to a brick building on the fringe of the park, a family picnicked next to a tree near the edge of the building and gave the two workers quizzical looks as the coverall wearing men propped the pipe they were carrying against the building the second they rounded the side of it.
"Whew, what a pain." One worker complained as soon as the pipe was put down. He pulled off his hard hat, revealing a headful of auburn colored hair.
The other worker rolled his eyes, not responding as he place the duffle bag he had been carrying on the other should down. He also pulled off his hard hat and wiped his brow.
Sento and Ryuga had decided to infiltrate the 'secure zone' as Sawa called it, hoping to find a way into Faust's base using the Nebula Gas trail Sento had found.
Ryuga watched Sento fiddle with the zipper on the duffle bag for a few moments before softly speaking. "Hey..."
Sento wrinkled his nose, giving the other man an annoyed look for a moment as if Ryuga was breaking his concentration with the stuck zipper or something and responded sharply, "What?"
"Y'know, about Tatsuya..."
Sento stopped fiddling with the bag and looked down at the mention of Tatsuya, a sad look creeping onto his face.
"I'm sorry." Ryuga had a somewhat sheepish, somewhat remorseful look on his face while trying to apologize to Sento.
Ryuga looked away, clearly embarrassed. If he had kept looking at Sento, he would have seen the large smile creep onto Sento's face for two seconds. Sento was pleased with how Ryuga had come around and said sorry for causing this whole mess.
Sento decided to tease Ryuga a little bit. "I'm not the one you need to apologize to." He said with a bit of a smirk left on his face.
Ryuga was about to retort but didn't get the chance. Sento pulled hard on the zipper of the duffle bag and a black, blue and orange blur streaked past Ryuga's head before slowing down and hovering in the air.
"W-What the?!" Ryuga's words were almost caught in his mouth for a moment after dodging the thing that had come shooting from the duffle.
He looked over at the grinning Sento and then back at the black, blue and orange, glossy square that was floating in the air around his head. It had four tiny legs, and a set of wings, long neck and tail that looked very dragon like.
Sento nodded at the small device flapping its wings while it orbited Ryuga with its chubby, cute body. It really looked more like a cute plastic child toy than anything else.
"That's for you."
Sento tilted his head and winked at Ryuga, "There's no telling what kind of trouble you'll get into."
With a growing smirk he tilted his head back in the other direction and said mockingly, "So you get a pet, and a babysitter."
Ryuga scrunched his nose and spat on the ground, clearly displeased. "I don't need any stinking babysitter!" He tried shooing the closely hovering device Sento had created away. He hit the end of what would be its face and mouth, causing the later to open and spew blue flames in his direction.
"Agh...Hot! What was that for?!"
Ryuga danced away while Sento started to chuckle. There was a child in the family nearby that looked up from his meal, attracted by the burst of blue flame and the cool looking 'remote control toy' that was buzzing about, avoiding Ryuga as he batted his hand at it.
The smile on the child's face fell when he took a good look at Ryuga.
With panic in his eyes, he pulled on his mother shirt sleeve and pointed in Sento and Ryuga's direction.
"Hey! It's that fugitive!" He cried out with a bit of fear evident in his voice.
"Ssssshhh!" Ryuga's eyes shot open and he held a finger up to his mouth.
The kid paid his shushing no attention and kept on shouting loudly, "Dad! Mom! That guy broke out of jail!"
Ryuga looked back in panic towards Sento and was shocked to see that he was on the roof of the building already.
"Hurry up!"
Ryuga stopped paying the family attention and raced up the side of the building using boxes and a several nearby tree branches that were in proximity to the wall.
The pair didn't wait around to find out if the family was going to notify the guards around the corner, they ran to the far side of the building, ditching their coveralls as they went. They climbed down, away from view of the guards and Sento lead the way towards the wall.
They got closer to the Sky Wall as they crept through long grass, finally coming to the place Sento had been looking for.
A large plume of thick, green smoke rose out of the wall, indicating that there was a very large hole there base on Sento's data.
"That's the place."
Two Guardians walked past the boys hiding place, they were patrolling this exact gas rupture, walking twenty feet in either direction down the path before turning around and coming back. Back and forth they went, Ryuga and Sento had watched them walk the same path ten times already.
When the guards were ten feet past the spot Sento and Ryuga were crouched in, Ryuga suddenly shot up, nudging Sento to follow, "Come on!"
They bolted past the guards into the smoke, the noise of their steps drew attention for a moment until the guards were distracted by a very fast black, blue and orange blur, flashing back and forth between their legs and past their heads.
It rocketed away into the air and disappeared, leaving the robots confused as to what had just happened.
Ryuga and Sento held cloths over their mouths as they walked through the dense green gas.
They were forced to stop suddenly as walls blocked their path from three directions. Ryuga turned and looked at Sento, "What now? It's a dead end."
Sento smiled and lifted up his Build driver in one hand.
"Then we make a path."
GORILLA! DIAMOND!
BEST MATCH!
Sento cranked the lever on his driver and called out, "Henshin!" Transforming into Kamen Rider Build.
GORILLAMOND!
READY? GO!
Build turned the lever again, building up the energy he needed for a special attack.
He pressed one hand against the nearby wall, and blue energy began leaking from it, spreading up the wall until it suddenly hardened into a thin diamond-like ice wall.
VORTEX FINISH!
The belt called out as Build cocked his giant right fist back. "Come on!" Build yelled as he hurled his fist forwards with incredible power.
BANG!
There was a small explosion as the Kamen Rider's fist demolished the wall, sending pieces of building and ground flying everywhere.
It exposed a tunnel underground, while Ryuga promptly fell into while cursing loudly.
He landed on his butt and a moment later Build jumped down beside him, executing a perfect superhero landing.
Ryuga was about to yell at Build until he noticed how familiar his new surrounding were.
His eyes shot open wide and he yelled, "This is it!"
It was the tunnel he had traversed down during his initial escape from Faust.
"This way!" Ryuga took off running through the tunnel, with the Rider following right behind him.
A few minutes after they disappeared down the tunnel, the dragon like device Sento made flew through the hole Kamen Rider Build had made, turned back and forth a few times before giving chase in the direction Ryuga and Build had gone.
They had successfully infiltrated Faust's secret base.
