My Own Science (Dr Stone Senku x reader)

Blow their minds

[For the little concert that's gonna happen, if you want some musical reference (meaning it won't sound technically the same, but the feel of it all is spot on), then I suggest INKIE's "keep it strange" in his loop station battle of 2018, iconic
Don't look it up now, you'll spoil yourself!]

Amaryllis came back and found the perfect spot: at the bottom of a mountain's cliff. Luckily it was an open space so the drone would fly freely. With everything ready, you all prepared to set out after instructing Mozu to tell Ibara that those hooded warriors gathered at this location.
But before that, you wanted to talk to Ryu.

"What is it?" he asked.
"I just realized something, and I wanted to thank you."
"Huh? For what?" he tilted his head.
"Well, because they couldn't see my face as a statue, I could really sell the role. So, in a way, you really did protect me."
He smiled softly.
"Oh dear (Y/n). You don't have to thank me for that. It's only natural."
He was going to say 'I love you after all', like he loved all women of course. But then he realized that it would make you uncomfortable, and it was the last thing he wanted.

So there you stood, wearing a beautiful dress and matching cloak both provided by Amaryllis and upgraded by Yuzuriha (yes there was a dress up montage), behind your hooded warriors and looking upon the enemy's army, with your electric guitar in your hands. You could've felt nervous, you could've. But you just knew this was gonna work! This time, your confidence was at an all time high.
'CEO Performer-(Y/n) just joined the fuckin party!'

You flinched when a beefy guy, who you assumed was their Magma (before all the character development of course), suddenly dashed towards you. Thankfully, Kinrou quickly defused the situation. He looked back at the enemy line.
"The holy priestess of our Kingdom wishes to settle this matter without bloodshed. Hear her words." he took a step aside so they could see you.
"Thank you Kinrou~." you took a step further. "Wassup?"
Mozu smiled, repressing a laugh.
"We're here because you have something that belongs to my ancestors, what you call your great leader's magic. And I would like it back." you paused. "Now, I'd understand if you don't believe me. Which is why I'm ready to demonstrate my powers to you all. Feel honored." Gen gave you a chair and you sat on it. "Because you're about to hear an exchange with the gods."

As you were placing your guitar on your lap, Kirisame looked at Ibara, waiting for his order.
"Let her be." he said. "I'm curious to see where this goes."

"First, let's give them something to work with."
You then proceeded to make various sounds and was given confused looks from your audience.
"There." you said. "Because the gods can't give you something out of nothing. Nothing can."
Senku smiled at that. You didn't even know this was a callback.

"Now." you lightly coughed and took a deep breath.
You started to sing a melody. Something with just a bit of uncanny valley to really catch their attention. And when you started to play your guitar, you heard one big gasp of shock.
Because here's the thing: the cell-phone (of course converted into an amplifier for this) was hidden in a very specific hidden place where the acoustic really hit the spot. So your audience was hearing the music all around them. The sound was rusty, but it really brought it home.

What you played was slow and simple because you didn't want to overheat the amplifier. But it was more than extraordinary to your audience, who literally has never heard something like this before.
Then, you stopped playing, you kept singing. A few moments later, your guitar solo was heard, but backwards.
And they lost their shit. It was clear the soldiers wanted to run away. Kirisame was speechless, Ibara was bewildered and Mozu...Mozu's face was priceless.

Here's how it worked: at the very bottom of the guitar's body were some little handles. With your cloak covering your arms, they were hidden and you could activate them without anyone seeing, with just a flick of the finger. Those handles were similar to the ones Ryusui used to control the drone. And the electric wires were going behind your hooded warriors so they were also undetectable. They were hooked by a record player set right beside the amplifier (made from scraps and your diamond), which was playing a glass record (made from one of the car's headlights) of your guitar solo plus the sound you made at the beginning turned into beatbox, all of which you recorded beforehand.
And so, you started playing with the handles, who simply made the record play forward or backward, stopping and starting again.
