[A Scientist's Weakspot] Ishigami Senkū x Reader

Chapter 15: Upgrades

Senkū chuckled while he looked at their automobile.

"We're going to power it up."

Kaseki was elated, flinging his arms in the air.

"Eh, really? In that case, Let's rebuild it! Quickly! Quickly!"

"In order to launch an attack that will rout our enemies, we'll turn it into a tank fortified with heavy armor!"

Y/N scratched her chin while Gen pondered,

"What will we use to make the tank?"

"Paper."

"I see. A paper tank. That will make it nice and light. UHHHH... WHAAAAATTT?!"

He smirked at Gen's reaction, looking at Y/N for help.

"But... Y/N, do you have any idea what we could use to make paper?"

"You're asking me this question when I thought you had the answer. If you really want me to answer that question, look over there."

He followed her finger that was pointing at a field of grass.  His right hand clenched into a fist, smacking it into his palm. Everyone ordered to collect as much grass as they can, which Suika did an extremely good job in. Y/N placed the grass in a sodium hydroxide pot, loosening the grass.

"We then need to wash it, press it and dry it... Hold up. I'm not the scientist here. WHAT ARE YOU DOING?!"

Senkū laid on his back, enjoying the sun that was shining on him. He shrugged his shoulders lazily,

"A scientist needs an assistant sometimes."

"But THIS scientist has a functioning brain and rested body, having no excuse as to why he is slacking."

"Fine. I'll help."

Once the thin sheets of paper were dried, Magam took one of the precious pieces and punched through it. Y/N's eyes widened, a precious piece of paper was ruined in just seconds.

"HOW IS THIS FLIMSY STUFF GONNA BE USEFUL?!"

"Magma!"

"O-Oh, sorry. Here."

She took the paper, tearing it into smaller pieces before stuffing into her pocket, which would probably be useful in the near future. Senkū chuckled, taking a grid that he had made with spare twigs. He placed several pieces and ironing the paper with a heated iron. When he took the final piece out, it looked more like a sturdy shield. Kinro took his spear, striking a tree down.

"Senkū, you might not know this, but spear users can pierce wooden shields in one strike. Do you really think you can deflect the Tsukasa army's weapons with that paper shield, or whatever it's called?"

"Oh, sure. Perfect time for a test isn't it. Kukuku~ Wanna give it a try?"

Suika shouted, getting the attention of everyone around.

"THIS IS HUGE! SENKŪ AND KINRO ARE GOING TO DO A BATTLE! AND NOT JUST WITH PRACTICE WEAPONS BUT REAL ONES, THEY SAID!"

The air went cold as the two prepared. Kinro struck with all his might, a loud banging sound was heard. Y/N panicked, thinking that the spear had pierced through the shield and stabbed him. However, Kinro's face went pale and in a few seconds, his spear fell apart. Kohaku shouted in excitement,

"Senkū wins!"

Senkū trembled, legs shaking from the force.

"Ah, wait, hold on a second. The one who can answer those questions is useless now."

Gen realized something, asking the lettuce-head an important question.

"Earlier, the stuff you painted onto the paper... Wasn't just some ordinary glue, was it?"

"Kukuku. Very good, ten to the power of fourteen points for you. The stuff that was painted was unhardened plastic. Mixing the flexibility of the paper with the hardness of the plastic brings us the explosive entrance of carbon fiber!"

Y/N took hold of several shields that he made, instructing him to make more while she arranged them and attached them onto the automobile. 

"I really hope Chrome's alright."

He comes up to pass her more shield, softly tapping her shoulder.

"We'll get him back."

The tank was finished and Kohaku used the telescope to spy on Tsukasa's base. She saw some commotion and a familiar being running towards them. 

"IT CAN'T BE! INCREDIBLE! CHROME BROKE OUT ALL BY HIMSELF!"

Out fo a sudden, Chrome coughed out blood, making everyone pale in worry. However, Senkū being the madman himself started laughing at the pool of blood.

"HAHAHAHAHA! THIS IS GREAT! SO IS THIS HOW YOU THREW OFF YOUR PURSUERS?!"

It was then they all realized that it was just vinegar and dried perilla. The science users tricked both the enemies and their own allies. Gen and Senkū decided to go to the cellphone, continuing their plan with Nikki. It seemed like they ran into a problem, Ukyo finding out that Gen was the fake Lilian Weisberg. Maybe it was the wrong choice to let Y/N hed out with Suika to bring some water for the villagers. It was definitely a bad choice, which they were about to understand why. The amazing occurrence of Ukyo being impressed by the kingdom of science, wanting to be an ally with the Ishigami village was another turning point to their goal.

Meanwhile, Suika and Y/N were by the riverside, grabbing a large pail of water while they did some small chitchat.

"Y/N, I want to be like you when I grow up!"

"W-What? That was a bit sudden."

"Can I marry you?"

"Huh? Suika, what's going on with this conversation?"

"I don't know! I just know that within us kids, we're all challenging each other for your hand in marriage! We won't lose to Senkū regardless of our age or gender."

"You guys are funny. But... Wait, one second. We're going the wrong way."

"Oh! I must have walked the wrong way. We have to go back because we took the wrong turn."

"I'm glad I have you. If not, I would have walked straight into Tsukasa."

"Hello there, fellow allies of Ishigami Senkū."
