My Own Science (Dr Stone Senku x reader)

You win some you lose some

"It's a good thing you made this decision Tsukasa." Senku said as he stepped out. "'Cause we just created dynamite!" he exclaimed with a huge smile.
"Senku! Fuckin christ! Read the room!" you exclaimed.

You turned around and saw him, Gen and. Chrome wielding big paper planes with some kind of liquid at the tip.
"That is not dynamite!"
"You're right, more like nitroglycerin, made from what's left of the tank."
Gen raised his arm with a smirk.
"Why don't we find out if it works? Just be careful, its force is roughly ten billion megaton joules~!"

"What tells us this isn't just a bluff?" Hyouga said.
"It's not a bluff, and no one's gonna use dynamite!" you turned towards him.
"You're just trying to stop us so you can use it against us once we have our back turned."
"No! Why would I do-?!"
"Because you're a liar, you just proved that you can't be trusted." he took a step forward.
"That's not-!" you took a step back.
"After all you fooled us for days."
"Hyouga." Tsukasa warned him.

He was about to continued when something caught your eye. The three of you looked up and saw one of the paper planes, flying high above everyone. It gently floated towards a tree, and created an explosion as soon as it hit it. Though it didn't hurt anyone, it was made clear that someone could die from it. You looked towards the cave. Senku had his arm outstretched, smiling.
"Now now now, let's respect the lady's wish, and just talk."
'You did not respect any wish! I said no dynamite!'

Tsukasa walked closer towards him while Hyouga stared at the spot where the paper plane hit, leaving a fire. He removed his mask, and you didn't like the smile he had. Still, you ignored him and followed Tsukasa, having more important things to do then to be creeped out by this creep.

"Though I made my decision, there was no way for us to make a move otherwise." he said. "The wide blast area makes it impossible to dodge. But, everyone would definitely get caught up by the explosion, and vast numbers would die." he paused. "Senku, you won't even sacrifice yourself, you aren't capable of abandoning people. You intentionally aimed to create this situation where both sides couldn't make a move."
"Yeah, pretty much." he casually shrugged.
"...okay." you said, trying to act as a third neutral party here. "So, is there any way for the two of you to you know, fuckin cooperate?"
"Kukuku, I can think of something." Senku said. "An exchange."
"Good, that's good. What is it?"
His expression became more serious.
"She's alive, isn't she Tsukasa? Your little sister."

You gasped, remembering hearing about her.
"Is she...? Like, in the same situation you were?"
"No, she's just in a coma."
You gasped again.
"In a coma?!" you looked at the other young man. "Tsukasa! We can heal her!"
"What?!" he asked, clearly shocked.
"Being revived from the petrification has restorative powers."
"That's how Senku was brought back to life!" you added. "He still had a fragment of stone on him!"
Tsukasa seemed to be at a loss for words.

"And so in order to bring her back, we need the revival formula. Oh! What's this?!" he tapped the cave with a scummy smile. "Would you look at that! It seems that *I'm* the one who has it right now!"
"And, so what do you want in exchange?" you asked.
"Easy. A change to revive his sister, in exchange for an armistice."
'Yes~! Good answer!'

"And do you have any basis on which I should trust something as hard to believe as that?" Tsukasa eventually asked.
You looked at Senku, waiting for his answer.
"...only my words." he said. "Science does not lie. Is that not enough?"
Tsukasa closed his eyes, his face towards the sky, he took a deep breath.
"No. It's plenty... It's more than enough."
You smiled.

You all went to where the hospital Tsukasa's sister was in. You set up camp and blew up the ground to save time so you could dig up afterwards. Luckily, no statues were blown too.
