IS Infinite Build


Construct 62: Vacation Gone Wrong.

Chifuyu: In the last Construct, more details of Sento's past is revealed, opinions were mixed. But Sento was soon challenged by Ichika and Houki to a battle, Sento won the battle but soon said that he was the Demon Scientist Katsuragi Takumi. A few days after this, the Freshmen of the IS academy go on a trip to the beach, but the team is restless… Sento…

We are Sento

I silently sit in the corner of my lab working on the Sclash Driver. It's not like we need this thing anymore… So why am… Oh, who am I kidding. I look at the belt. "This belt… Is the collective culmination of 10 years and hundreds of bodies… Why am I still BUILDING IT!" Inraged I stand up from my seat and throw the belt at the wall, it hits the wall and falls to the ground, some of the parts fall out of the belt. I sigh as I fall back into my seat, putting my hands in my face I let out a groan of pain. "Sento?" I look up to see Chloe.

Sento:(stands up) Sorry, was I making too much noise?

Chloe:(walks in) Yeah… Are you holding up?

Sento:(chuckles) No better than before, still working on that stupid belt.

Chloe:(walks over to pick up belt) Why don't to do something else, it might get your mind off the work.(picks up belt) Don't forget to clean up.

"Yeah, sure." Chloe hands me the belt and I place it back in the tool box. I stand up and walk up to the Cafe. "Mind making me an espresso?" Chloe asks me, I walk over to the coffee machine and make an espresso. "Here you- Do you hear that?" I hear the sound of water running, placing down the expresso I turn around to the sink to see the water from into that like a snake. "Whaa~!" Chloe exclaims standing up. Ah, this is advance manipulation of water and from the looks of it, it is a special type of water. The water flies over the door and opens the door, and in through the door comes Sarashiki-chan the IS academy's Student council president.

Tatenashi:(smiles) Hello, Sento Sensei. How are you?

Sento:(sighs)... Sarashiki-chan…(points to water) The water?

Tatenashi:(opens fan) Of course. Pardon my entrance.

A lance is summoned into her hand as the water returns into the lance and closes up before disappearing. Sarashiki Tatenashi, she has short light blue hair, dark red eyes and a voluptuous figure, with slender thighs, a narrow waist and large breasts. She's dressed in her IS Academy uniform, it consists of the typical white and red blouse, a skirt that is short compared to others with a yellow tie, along with red leggings. I sigh before pointing to the sink.

Sento: Sarashiki-chan. Why was you're water in the sink?

Tatenashi:(closes fan) That, well the thing is, I was wondering where you were and I looked up you're home address and found you here. I came by, but only to find that the door was locked, I knocked but I was told to go away or leave the mail by the door. Thus I decided to send a message to you Sensei, but you wouldn't respond thus I sent some of my water through the sewers to open the door, to see that you were here with… Oh, you must Chronicle correct?

Chloe:(nods) Y-yes…

Tatenashi:(bows) Nice to meet you. You were exactly as I heard you, you really are twins then huh? You and Laura.

Sento:(sighs) Please Sarashiki-chan… What can I do for you today? You wouldn't seek me out like this unless you needed something of me.

Tatenashi:(smirks) Straight to the point.(opens fan) That's something I like about you Sensei. You don't waste any time, but you're right. On to the topic of my visit. Simply put, I need your technical expertise to help work on a IS.

Sento:(turns around) If you need me to fix something ask the repair crew, that's what they are their for.

Tatenashi:(walks over) No, this is something that requires the work of someone who can build an entire IS suit from the ground up.

Sento:(looks at Sarashiki) What? Why?

Tatenashi: You see...


We are Ichika

After a day of fun for everyone else, we return to the inn and have dinner… But I still just can't sit still. Under the night sky, I do push ups and try to keep my body moving. "Ichika?" I hear as I turn to Cecilia dressed in the inns night robes. "Hey." I say as I go straight back to my push ups. "So you really have been like this since we got here then, huh?" Cecilia says kneeling down before sitting on the wood.

Ichika:(stands up) Can't help it.(starts boxing) I'm still trying to help Houki, but sitting around thinking isn't my style.

Cecilia:(giggles) So, you start working out? Well I suppose it's one way of handling stress. Not to mention quite the sight for me.

Ichika:(pauses, turns to Cecilia) This isn't a show you know?(Cecilia smiles)... Oh forget it…(continues) Hey, I need to ask you something serious.

Cecilia: Hmm? What is it?

Ichika:(kicks) You really think that Sento-sensei really is the same person who created Faust, the Smash, Build, and subsequently created Kaiser?

Cecilia:(tucks feet in) … I don't know. A part of me that Sento isn't that kind of man. But looking at the bigger picture says that there's a chance. Takumi's sudden disappearance later made to be a murder after a year of investigation, Stalk's constant manipulation, Sento's mannerisms, but then I have to feel sorry for Sato Taro. He died without even knowing why he had to die.

Ichika:(punches) That's exactly what pisses me off. I know that Houki feels the same way, but…

Cecilia:(smiles) Sensei would say that rushing into something without thinking is something that a meathead like you would do.

Ichika:(looks at Cecilia) Very funny… But as we are now… We're in big trouble if someone were to attack us.(slaps self) Which is why I need to figure out a way of getting Houki back on her feet so we can fight together without worry.

Cecilia smiles as she hands a towel. "Then make sure you get enough rest so that you don't get shot down if that fight comes." She tells me, I smile as I walk over to grab the towel. But I hit a rock and I trip. "Whoa! Whoa! Whoa! Whoa~!" I landed straight on Cecilia. "Crap my ba-" I freeze at the sight before me. In the fall I had pulled back her robe to see her underwear… Black?! "I-I didn't know you were into that." I mutter in disbelief. "Please get off." Cecilia asks me blushing.

Ichika:(blushing) Ah! S-Sorry!(backs off) Sorry-

Rin:(dark aura) I-Chi-Ka?!

Ichika:(turns around) Rin?! How long were you there?!

Rin:(partially deploys IS) Long enough to see a Pervert make his move. Explain what happened to me, Now. Before I beat your face in.

In fear I pull out my Dragon Full Bottle. "Okay, let me explain all this. Just don't punch me." I say with Rin slowly approaching me. "Come on… Explain." Rin mutters. "We… Uh… it's like this-"

We are Chifuyu

"I'm Sorry~!?" Is shouted from outside, I look to where the shout came from. Opening the door a little to peek outside. Just to see Ichika explaining a misunderstanding to Rin, as she looks just about ready to pummel Ichika into the ground. "Shure is noisy out there." Sento says from over the phone.

Chifuyu:(sighs) It's the idiots being idiots. Back to what we were talking about. You're going to help Sarashiki's sister with building an IS?

Sento:(shrugs) I have nothing else to do and I've already finished creating the Sclash Driver, despite… A bit of an accident. Oh who am I kidding, I threw it at the wall. Pretty much pushing me back in my work on it.

Chifuyu:(worried) Sento… I was only going to say that it's a good idea. Building something that isn't relating to the Rider system would do you some good. Or you could have come with us. I was sure some time away from all the fighting would do you some good.

Sento:(leans back and covers eyes with arm) Yeah. Figured it was something like that. While I do appreciate the idea… Just… It feels like I don't deserve to let them call me a teacher.

Chifuyu:(crosses arms) You know that's not how they feel. They feel grateful for what you have done for them… Forget it, what's done is done. But if you need help, I'm always here to lend an ear and an opinion.

Sento:(smiles) Yeah. That's why I called you in the first place…(sighs) Thank you.

Chifuyu:(smiles) No problem. I'm always here for you Sento.

Sento:(nods) That's something that I love about you. I'll be in touch, let me know if anything happens okay?(Chifuyu nods) Thanks.

Sento ends the call, I smile after hearing him say those words. "Was that Sento-san?" Yamada-san asks entering the room. "Yes, I was checking on how he was holding up." I tell her. "Seems that Sarashiki had a task for him, to distract him from you know." I tell Yamada, she nods handing me a beer. "I see. That's good to hear." I take the beer from her and crack it open. "Let's hope this helps Sento get his mind cleared up." I mutter looking up at the night sky.


We are Sento… IS Academy IS Bay

I walk into the IS docking bay to see Sarashiki Kanzashi, younger sister to Tatenashi. Kanzashi has blue hair and dark red eyes like her older sister. In opposite to Tatenashi, Kanzashi's hair curl inwards and is slightly longer, and has a more petite body compared to her older sister. Her IS academy uniform consists of the typical white and red blouse with two triangular hairpins on both sides of her head and yellow leggings. She also wears a pair of glasses. She silently works on modifications on one of the training units. I knock on a crate to get her attention, she freezes before slowly turning to see me.

Kanzashi:(surprised) S-Sensei?! Wh-What brings you here?

Sento:(walks over) Don't worry, you're not in any trouble. But what are you doing here? Shouldn't you be on the Field Trip?

Kanzashi: Oh, um… That's because no one would be around and I could work alone… Why are you here Sensei? Weren't you put on the list of staff to go after Ichijo-sensei had to leave.

Sento: Ah… That. Well, I was feeling under the weather and decided to stay behind. All nighters will do that to you. But I heard that you were working on your own Personal IS using one of the practice ones?

Kanzashi:(looks at IS) Ah, Yes… But I'm not making too much progress, which is why I was hoping that with the Freshmen gone, I could work on the IS a lot faster.

Sento:(walks over) You do know, that for even one company to produce a modification would take a whole team to make. You know that right? You can't do something like this by yourself.

Kanzashi lowers her head, but then looks back up at her IS. "But… I have to try at least." She mutters. "Come on Sen-chan, even if something seems impossible at first. If you try it, then you may find that it's easier than you think. Especially if you have a genius!" Tabane's words still echo in my head. Even if the woman known as Shinonono Tabane is dead in my heart, I can still keep her words alive… I walked over to her desktop and open the programing tab. "Sensei?" Kanzashi asks.

Sento: Well? Aren't we going to work on this? It may be impossible alone, but with a Genius like me, it will make it easier to create. So? Are you going to stand there and do nothing?

Kanzashi: Ah!(Rushes over) Right! Thank you!


The next day… We are Ichika

The next day, everyone is readying to practice with their IS's. Tests are being run, staff running around, students being tested and matches are underway. Despite everything going as planned, I can't feel safe for some reason. Why do I feel like someone is telling me that something's wrong? Ever since this morning, I feel a bad feeling of unease. "Is something wrong?" Laura asks me.

Ichika:(crosses arms) Dunno. Maybe it's because I've been on the run all the time, but I feel like something bad is going to happen.

Laura:(nods) Yes. I understand. This calm… It's just begging for someone to disrupt it.

Yamada:(runs over) Banjou-Sensei! It's an emergency!

Chifuyu:(turns to Yamada) What? What is it?...

Cecilia:(walks over to Ichika) What could it be…?

Ichika:(clenches fist) Trouble.

Chifuyu:(turns to everyone) Attention everyone! Form this point on, the facility will be conducting a top-secret mission! All test Operations today are cancelled! Each group will put their units back, and return to their respective rooms at the Inn! If you do not have the proper clearance going outside of your room is strictly forbidden!

Class:(in synch) Y-Yes!

Chifuyu: Everyone with personal units, come over here!

Ichika:(walks over) What's happening?

Chifuyu: I assume that you and Houki brought you're Drivers and bottles?

"Course, everywhere we go." I tell her, Banjou-Sensei gestures us to follow her. We all follow her towards a command center that is being set up in an empty room in the inn.


We are Sento

I press the enter key, as the screen comes up as complete. "It's done..." I mutter. "It's finished." Kanzashi mutters. We both smile as I stand up and we jump for joy. "It's done! We finished it!" We shout in synch, we look upon the now complete Uchigane Nishiki. Designed for Long Range and close quarters combat, it's armaments allow it to combat in both ranges.

Kanzashi:(looks at IS) It's… Even better than when I originally planned it… I never thought I could create a real Beam Saber!

Sento:(smiles) Of course you can! Creating a Magnetic field and plasma is the easy part. Powering it is the hard part, but the carbon Grid allows for more effective power distribution and can make the possibility of a Beam Saber a reality.

Kanzashi:(hand on chin) So that's how the Yukihira works. I just figured that they used a second power source within the blade itself.

Sento:(chuckles) Of course not. That would increase the weight and would be more dangerous to have such a source so close to a pilot. But I'm surprised you're modifications on the Shunrai.

Kanzashi: I based it off the GM Sniper 2's beam sniper, as well as the sniper of the Blue Tears. Effectively increasing the range of the shots when compared to the Blue Tears. The Mountain Storm is a nice addition, the reloading mechanism is brilliant!

Sento:(crosses arms) Yes, and your container for the Mountain Storm is the perfect place. Allowing for simple teleportation of ordinance for speed reloading is a nice idea. But what do you think of my special attachments?

Kanzashi:(turns to Sento) Their brilliant! You really are a Genius! The Beam Saber, Ignition boost, even the funnels! I never throught it was possible to make funnels like Blue Tears and be able to manage them while still moving. I thought you needed to be a Newtype for that.

Sento:(sweatdrop) Let's not bring up the Space magic of Newtypes. The IS system has an onboard AI program of sorts, if you input commands the IS system will manage the movement of the Funnels. Sigh~ But it's unfortunate that I was only able to make the Funnels be machine guns.

Kanzashi:(shakes head) No! It's cool even being able to do that!(looks at IS) This… My own IS. I would have never been able to complete or even have the level of advance tech without the Genius Teacher!(turns to Sento) You really are!

Sento:(smiles) Of course! When a Genius is working with you. You're end result it sure to be amazing!(notification sound) Hmm?

"What is it?" Kanzashi asks. I open my HUD and see that it's a message. "Just a message from Chifuyu." I tell Kanzashi, I open the message. It reads 'A Hijacked IS is moving towards our location. It's likely the ones who stole it are trying to strike us while we are weakened. Get here if you can.' I'm shocked by the words. What? So then the IS's that attacked the academy previously, they must still be under Faust control… I turn to leave, "Are you saying that you have never hurt anyone?" Stalk echos.

"You were just playing Kamen Rider..."

"You are Sento… You are the Demonic Scientist Katsuragi Takumi!"

I clench my hand. "Sensei? Is something the matter?" Kanzashi asks me. I smile and turn to her. "Nothing, just more work came up since I'm here is all. Good work today!" I tell her as I go to leave. "Sensei. What is happening?" Kanzashi asks... "A top-secret mission." I tell her, she backs off. "I see." She says, I walk to the door but before I open it, Kanzashi asks me again.

Kanzashi: Hey… Sensei? What are your thoughts on Kamen Rider Build?

Sento: … What hasn't already been said?

Kanzashi:(looks at IS) I don't believe what they said about how the Kamen Riders are Fugitives. They are heroes! I read the stories, when people were in trouble he came to help us. Those times when IS when beseark, he was their… To save us.

Sento:(turns to Kanzashi) What's this all of a sudden?

Kanzashi: I just… I… I've always felt so small. Especially when compared to my sister. She so much better than me. Smarter, stronger, prettier, she's better than me in every single way. So I've always been… A bit of a shut in, but with my own IS. Built an IS with my own hands… It makes me wonder if this is how Build feels when he helps someone. Great happiness in the work he does… I've always look up to heroes like Build. They don't make me feel so… Small, like I'm important to them…

Sento: … Kanzashi.(blank face) You'd better not be thinking of taking you're IS outside of School grounds without permission, I swear if you do. You will not be able to keep you're Japan Cadet Rep authorities with you. I will take away you're IS as well.

Kanzashi:(turns to Sento) I-I would never dream of that! I just… Wonder if you feel like that when you help someone like me out. Someone who is so… Little... I just felt like I should share this with you… Since you never once compared me to my sister… Unlike everyone else, they always seem to compare me with my sister.

Sento:(Walks over to Kanzashi) Kanzashi-chan. You are not like you're older sister. That is true. But you are not little compared to her, nor are you bigger than her. You're twins but you're different. Don't compare yourself to Tatenashi-chan, that's not right. Not right to you, you are you. Not Tatenashi, not me. You… Are Sarashiki Kanzashi, you pilot the Uchigane Nishiki, you're IS, that you built yourself, you are Japan's IS Cadet Rep. You are, not Tatenashi. You are you.(pats Kanzashi) Don't doubt yourself, only you decide if you are good or not. Not your sister, not me. No one but you. Do you understand?

Kanzashi:(slowly nods) Y-yes. I think so…

Sento:(smiles) Good, I need to go. But remember, you are you're own person. It's not good to always go and compare yourself to others. It's good to gauge where you are in ability, but don't see it as a wall. See it as an obstacle, a hurdle that with enough effort you can jump over. So you got it okay?

Kanzashi:(nods) Yes! Thank you Sensei!

"Good to hear." With that I walk off and leave the room. Walking back to my office, stop in the middle of the hall and I look at my Rabbit Full Bottle… I don't need this bottle to help people… Yes. I don't… Have to be Build… Right? I clench the Rabbit bottle tightly.
