Construct 69: The Golden Soldier

Sento: Kamen Rider Build, the brilliant physicist Kiryu Sento is shocked that he is the founder of the Evil organization Faust, Katsuragi Takumi. Not long after, war breaks out between Touto and Hokuto. Sento has resolved to fight, in order to protect Touto.

Gen: I see. So you've made your decision, then.

Sento:(off put) Whoa~, Gentoku…

Gen: Call me Prime Minister Himuro. The time has come for Touto's counterattack. We'll crush Hokuto!

Maya: Sir! We don't have the manpower to even attempt an assault like that! We can't pull any units either!

Sento: Well, when she puts it that way, maybe I should reconsider…

Gen: Then I won't put it that way!

Sento: You're so fickle! Now, what'll happen in Construct 69!?


We are Sento

We stare at the girl whose face is hidden under her hood. "Who said you guys could leave me out of the fun? Come on." She says as she reaches into her jacket and pulls out a Sclash Driver. "Sclash Driver!" "That Driver..." I mutter. "How does Hokuto have it?!" Cross-Z asks. "She's pissed off, huh?" Old Blue mutters behind the woman. "Seems that way." Short Yellow responds.

Tall Red:(rushes over) Where have you been, Boss? You're late!

Girl:(shoves Red back) And you all ditched me, when you know I get easily lost.(points at Cross-Z) Or did you mistake him for me?

Build, Cross-Z, Akats:(confused in synch) What?

The girl looks at us, before reaching up to her hood and pulling it back revealing that the girl before us has the exact features as Chifuyu in face and body features as Chifuyu Orimura in her high school days. Compared to Chifuyu and Ichika, this girl appears to have a petite body and has the same hairstyle as Chifuyu. "Nice to meet you… Onii-san." She mutters.

Build:(shocked) This is the worst possible outcome?!

Akats:(shocked) Completely out of left field…

Cross-Z:(shocked) EEEEEEHHHHH~!(falls back)

Cross-Z falls back onto the ground, causing everyone else to pause in confusion. "I-Is he okay?" The girl asks, Akatsu and I look at the passed out Cross-Z on the ground. "Eh, give him a sec." I to her, before I kick Ichika in the groin. He immediately gets up and looks at me. "Ow! Don't do that!" He shouts at me rubbing the right side of his groin. "So what happened?" He asks, then he looks at the girl in front of us, blinking for a few seconds. "Is that a smaller Chifuyu-nee?" He asks.

Girl:(raises eyebrow) ...Wow… I mean, I knew that my brother is stupid, but forgetful too?

Cross-Z: Hey! At least call me a Meathead! And who are you?

Short Yellow:(begging) Forget that! Boss, get the bottles back!

Girl: Well, since you asked…(raises jelly) Guess I'll do just that.

Opening the Jelly in her left hand, the girl tosses the jelly into her right hand. Then flipping it upside down she inserts the jelly into the driver. "Robot Jelly!" The belt exclaims as steam work almost robotic music begins playing as the girl brought her left arm up, one finger and her thumb pointing out. Bringing the arm from up in front of her to her side where she points to us. "Henshin." She mutters before bringing her right arm down and turns the wrench levear. The press squeezes the jelly, as the jelly enters the container, steam exuding out of the belt. Forming around her the beaker frame generates black almost black oil like substance. The girl gestures us to come get her before putting her arm down and the beaker twists. "Crush! Flow! Overflow!" The suit's helmet bursts out a grease substance that glows and shines almost like it is gold. The grease substance covers the helmet, chest, and shoulder pieces before it hardens and blasts off the excess ooz. "Robot In Grease! BURRRAA~!" A new Rider stands before us.

Grease: Kamen Rider Grease… Is here.

Build: Kamen Rider… Grease?


Grease's suit has a color palette of Gold, Black, dark Brown, with bits of white. The undersuit's chest and waist are black, with gold at the elbow. The waist down is gold, white writing and markings on the thighs. The helmet has the same white underhelmet with red eyes, but with the shape of the outer helmet begin robotic, symmetrical, and with a single horn. The lower chest is similar that it's translucent like the helmet with the gold under chest plate, at the back is a pair of vents with two more nozzles on each vent. Shoulder armor is gold like other parts of the armor, with flat shoulder plates on the shoulder armor, with a nozzle at the bottom of each, on both plates is a symbol of a robotic claw. At each arm are gold gauntlets each with a nozzle above the wrist, under the wrist is a pair of small needle's. At the legs are gold knee armor, at the legs are black armor, with gold brace at the ankle, the shoes are like Greases but with a nozzle at the tips of the feet.


Grease: The fire in my heart… My passion.(hits knuckle against chest) I'll let my passion burn and Crush you!

Cross-Z:(nods) Oohh~(helmet folds on) Bring it on, then!

Cross-Z charges in and smacks Grease in the face before he grabs her by the shoulder and turns Grease to face him. Grease blocks Cross-Z's attacks, before Cross-Z gets some hits in with the Twin Breaker. Grease seems like she's not even phased by his attacks!? Grease takes the hits. "You talk big, but you're hardly putting up a fight!" Cross-Z exclaims, before thrusting his drill at Grease, which she just grabs. "That's all "You" got?" Grease says as she lifts up her left hand and points and shows her palm, energy charges up before being blasted straight into Cross-Z blasting him back. Cross-Z flies back into a tree, then from Grease's gauntlet shoots out the grease substance that forms into the Twin Breaker. "Twin Breaker!" Grease reaches to grab something.

Grease: That's not gonna cut it!(takes out bottle, shakes)

"Helicopter!" Grease removes the Jelly from her belt before replacing it with the Full Bottle. "Discharge Bottle!" Grease presses down on the wrench lever. "Uncrushed! Discharge Crush!" The Oil substance shoots out and forms helicopter blades that spins lifting Grease into the air. "Alright, here it comes!" She exclaims, as she flies up she opens fire on Cross-Z flying by him. Grease flies all around Cross-Z all while he just take it, then Grease flies down and slams into Cross-Z kicking him to the ground. Grease lands back on the ground returning her jelly back into the belt, and looks at Cross-Z. "We're still not done!" She shouts as the shoulder plates shift to face Cross-Z. "Wha-" The nozzles shoot off Plasma blasting Cross-Z as Grease charges up close. Grease and Cross-Z engage in fist to fist. Grease is faster than Cross-Z, Grease getting multiple hits in before flipping forward, the nozzle on Grease's foot propels her foot straight into Cross-Z's head knocking him to the ground. Grease presses down on the wrench lever. "Scrap Finish!" Grease prepares, shifting her stance into a launch position. The shoulder armor faces back as the nozzles on the back and on the shoulder blast out the grease substance at such high pressure that it propels Grease forward. Grease enters a kick and slams into Cross-Z blasting him away.

Build and Akats:(running over) Ichika!

Chloe:(runs over to Cross-Z) You okay, Banjou!?

Grease:(stares at Chloe) …

Tall Red:(runs over) Boss, finish them!(peace sign)

Build:(helmet folds on) As if I'd let you! We're not letting you close!

Akatsu:(helmet folds on) We aren't slackers ourselfs!

Grease stares at us, before letting out a sigh. "Chill you two. I'm done today." Grease says as her helmet melts and is sucked back into the under helmet before it folds away. Grease's hair has turned golden, and her eyes also gold with a black pupil. Like the opposite of Chloe almost... "Wait, but the bottles…?" Tall Red asks with the Trio surprised. Grease looks at me, before scoffing and turning away. "Kiryu Sento… She fell for him?... Sigh~ Whatever, I don't feel right taking them after butting into a fight." She explains walking over to the Trio.

Short Yellow: What the heck kinda rule is that? You're one capricious dude!

Grease:(looks at Trio) More over… It's because of you three ditching me that you got into this mess in the first place! This is why they put me in charge!

Build: Where did you get that Driver?

Grease:(faces Build) Oh, this?(looks down at Driver.) A funny cosplay chick gave it to me. We'll be coming for the Bottles. Keep your compound eyes peeled for me. See you around, Brother. And say hi to Big sister for me huh?

Akats: What relation do you have with Ichika!? Who are you!?

Grease pauses before removing the jelly and returning to her normal form. "Me?... Heh, Big sis will know. Just you wait." Grease says before leaving. "Just you wait!" Tall Red exclaims and the Trio leave. "Hey!" Cross-Z tries to get up, but we stop him. "Stop, drop the transformation. It's over." I tell him.

We are M

As I walk away, I turn back to look at the four. That girl seems familiar… I look at the Russian girl… Naw, it's just my imagination. As if she would be out in the open like that. I think to myself before leaving.


Later… We are Sento

Back in the Cafe, we rondevu with Chifuyu, Tatenashi, Kanzashi, Sawa, Chloe, Ichika, and Huoki. I look through my research data to check. "The data from the research has been copied. So now, that's both the power and the Driver." I confirm, looking at recent activity. "It must've been back then..." Chloe remembers back.

Chloe: I'm sorry I didn't notice.

Sento:(smiles) It's my fault, I should've been more careful.(looks over) More importantly…

I walk over to the Sclash Driver and Dragon Sclash Jelly, I grab it form besides Ichika. "You're not using this anymore." I say stepping away. "Why the hell not? I saved your butt with it!" Ichika exclaims standing and walking over to me. "That's the problem." "Eh?" Everyone looks at me, I turn to face Ichika. "You're stealing my heroic thunder!" I pronounce, everyone processes the info.

Ichika:(confused) HAAA~?!

Kanzashi and Tatenashi:(knocked off balance) What?!

Chifuyu:(sighs) Oh, boy.

Sawa: Ha~?

Chloe:(grunts)

Houki:(facepalms)...

Sento:(paces around Ichika) Build is Touto's superhero! Plus, we can't possibly have the supporting cast overshadow me.(paces backwards) You'd make all of Touto's kids sad!

Ichika:(looks at Sento) What do you mean supporting cast?!(walks to Sento) This isn't a TV Kids Drama! Is all you care about showing-

Sento:(walks past Ichika) Alright, are we done here?(looks at Chifuyu) Speaking of, we have a more important topic to discuss, the fact that Kamen Rider Grease. Hokuto's Kamen Rider, has the face of Chifuyu. She said that you knew something about that.

Houki:(looks at Chifuyu) Right, it was undeniable that you two have the same face. Though she looks like you during your High School days. Just with shorter hair.

Chifuyu: …(sighs) It never really came up because for a long while… I thought she was dead.

Everyone looks at Chifuyu confused. "Ichika… When you were born. You weren't born alone." Chifuyu explains, Ichika is confused before he begins to put the pieces together. "Wait… No." He mutters. "She… She can't be..." Ichika mutters. "She is… Grease… is you're twin sister." Chifuyu tells everyone. Everyone in the room takes time to process this.

Sento:(surprised) What a twist.

Kanzashi and Tatenashi:(look at each other) …

Sawa:(raises eyebrow) I'm sorry. Did I just hear that Hokuto's Rider is actually, Banjou-kun's lost twin sister?!

Houki:(looks at Ichika) Ichika...

Chloe:(shocked) Wha… I-I… Wha?

Chifuyu: When you were delivered, I was told that mother was having twins… But the twin girl died in the womb. You survived healthy, but she had been choked. But from the video, it's clear that shes the same age as you. Which points to her.

Ichika:(looks at Chifuyu) What's her name? Did our "Parents" tell you anything about her?

Chifuyu shakes her head. "Nothing, not too long after. Our parents abandoned us." Chifuyu explains, I put a hand on my chin. So then was Madoka taken away? Why? Was she perhaps sold off? I ponder the possibilities but nothing concrete. I sigh and shrug, "Oh well, I guess we should put that off to another time." I say.

Ichika: No I think we shou-

Sento: I said we should put it off, go pump some iron or something.(Phone rings) Hmm?...

Chloe:(looks at Sento) Who is it?... Sento?

As I leave a chuckle as I look back at Chloe. "Come on, really? Asking is kinda rude, y'know?" I say before putting out my pinky finger. "It's this." Chloe lifts up her pinky and looks at it confused. "You know..." I say winking then leaving. "W-Wait, Sento has a mistress or something?" Sawa asks as I leave. "Gasp! No way!" I hear Chloe exclaim. Leaving into the main cafe area I look at the caller. Tabane. I answer the call.

Sento: What do you want?

Tabane: Burr~, so chilly Sen-chan.

Sento: We were just talking about you and you're new Rider.

Tabane: Ah~ M-chan and the Sclash Driver? Heh, sorry for swiping your data.

Sento: Even with that data, actually putting the belt together would require serious skills. So answer me clearly, no bullshit. Who built it?

Tabane: Who else? Nanba Heavy Industries. By the way… I see you let Ichika use the Sclash Driver.

Sento: Yeah, well he's not going to be using it again. I won't let him use it anymore. In exchange for using the full potential of the Bottle's essence, the Sclash Driver exposes the user to the unshielded effects of Nebula Gas. Those affected are similar to what's seen in people exposed to the Light of the Pandora's Box. With every transformation, the user will grow increasingly aggressive, and become more obsessed with fighting. Taming that requires a lot of resolve and power.

Tabane: But without the Sclash Driver, you can't beat the Hokuto's boys.

Sento: Exactly why I'll use it. I'm going to protect them, no matter what. I'm his teacher, better that the adult protects who comes after him. Unlike you and Grease. So, you've defected to Hokuto?

Tabane: You could say that. But relax~ Sento. I haven't told them where you are all hiding. Gotta keep the game interesting, right?

Sento: Just what are you after?

Tabane: Oh, Sento. Quit making me repeat myself… I want to see you boys grow. Me and those in Phantom Task give our regards for a good game. Ciao!

The call ends as I lower my phone. Phantom Task, no wonder. A terrorist cell that was rumored to have been around since the end of World War II. An idea forms in my head. Was Grease taken from Ichika's family by Phantom Task? Trained to become a soldier? I wonder if the previous attacks on the IS were not just Faust but also Phantom Task too? I let out a tired sigh as I lean back in my chair.


The next day… Touto Government building

Houki and I begrudgingly put back on our tracking bands. We look at Gen who sits in his chair. "I see you've decided to cooperate." Gen says, "Not as a weapon. This is to protect Touto." I respond. "Your rationale doesn't matter to me." Gen says taking a tablet and looks it over.

Gen: Tell me, how did Hokuto get their hands on the Sclash Driver?

Houki: My sister…(looks at Gen) She stole the data then defected to Hokuto.

Sento:(looks at Gen) And with the help from Nanba Industries constructed it.

Gen:(hand on chin) So, it was Nanba… It's time to find out what exactly they're after.(stands up) What?(whisper into ear) TV on, switch to news.

Hmm? The three of us look at TV, to see Grease's or M's face. "Ladies and Gentlemen." She announces herself. "It's her!" Ichika exclaims as we surround the TV. "I'm Hokuto's Kamen Rider, Grease or M. Don't mistake me with Chifuyu, I have no relation to her." Grease clarifies to the screen. The Trio and Grease must have taken over the TV station!


Touto TV Station… We are Observer

Owl walks up to the man operating the Broadcast. "Heh! Keep that Live Broadcast rolling!" In the main room, Stag and Castle keep the hostages in check. "We are finally at war." M explains. "But, thanks to the Sky Wall, we can't really move our tanks, battleships, or air power around." M further explains as she steps forward, taking out her Sclash Driver and shows it to the Camera.

M: So, that makes the IS and Rider tech. The most powerful weapons in this fight.

M incerts the jelly into the belt. "Robot Jelly!" "Henshin." She mutters turning the Wrench down as the frame sets up and armor liquid engulfs her. "Crush! Flow! Overflow! Robot in Grease! BURRRRAA~!" Grease stands in her Rider armor and stares directly into the screen.

Grease: We only want the Pandora's Box that's in your Governments custody, and the bottles of Kamen Rider Build.(turns away from camera) Once we get those, we'll pack up and head home. But if they're not handed over, we'll be coming for them with force. But don't worry you're scared little faces. Starting today, we're adopting a policy of not harming civilians. Best to keep the fight between those who can fight, huh? So, you stay at home and stay quiet, and you'll just be fine. Less blood the better.(walks up to camera) But, if you show up on the battlefield, consider that safety forfeit.


Touto Government… We are Sento

Gen: Maya!

Maya:(looks at Gen) Y-Yes Sir?

Gen:(walks past) I want Guardians at that studio!

"Yes, sir!" Maya exclaims as she sets about sending the Guardians, then Gen turns to us. "You three as well. Get on it!" Gen orders us, I go to leave but Houki and Ichika are hesitant. "You're gonna fight with the Sclash Driver?" Ichika asks me, I pause before looking back at him. "If you can use it, then of course I can. I'm not gonna give up my spotlight so easily." I say as I go to leave when Maya stops us.

Maya:(steps over) We have a problem. We have reports of Smash in the district next over from the Station, we need someone to check out.

Gen: Then send a squad to investigate. The station takes precedence.

Maya: My thoughts exactly, but when I sent the squad… They reported that Stalk was their.

"Stalk?!" Ichika and I exclaim in surprise. "I'll go. You two go." Houki tells us. I look at her the clear look of determination in her eyes. "Are you sure?" I ask her, she gives me a solid nod. I look at Ichika who looks concerned. "I'll be fine Ichika. Trust me." Houki assures, Ichika ponders before nodding. "Okay, be safe." Ichika tells her as Houki walks over kissing Ichika on the cheek before leaving.

Sento:(walks over to Ichika) So I'm sure that's a "you too."

Ichika:(nods) Yeah, come on.

We are Houki

Leaving the room, I can't help but clench my hand into a fist. "You'll see me again soon." She told me in the private chat we had… Tabane… What's your plan? I ponder as I leave the building and get on one of the Government's bikes given to us. Revving the engine, I drive off.
