Senku Ishigami One shots

Observing

(Time set in the Stone world. Ooc Senku [yandere])

'I don't like this feeling. It make me think of.. 'different' ways to use science. All just for her.' A scientist thought to himself as he took in the sight of his ray of sunshine.

He wants her brightness all to himself.

(Y/n) has easily enchanted the village to liking her. With a bubbly personality and easy to get along to. You can say she basically fits in with everyone.

And Senku doesn't like that. Not one bit.

He may have regretted de-petrifying you this early. But he was in need of man power and someone who can understand him and his obsession towards science.

It was her that was with him.

He wants her and nobody else.

He was so bothered by how close you have become with the villagers. Specially, when you would smile and laugh with them.

Your smiles were meant to be his.

"Lettuce head?" A soothing voice cuts through his mind. As he looked up to see the one he was thinking about.

"What is it you need?" He asked.

"Is there something bothering you?" You asked sitting beside him as he works.

Debating his choices and probability of how  things will go. He settled unto asking you for help with his current predicament.

"Will you help me understand this feeling then?" He asked taking a glance at you.

You perked up at that. Wanting to know more what was going on within his mind. Specially, his emotional state for he would mainly show his excitement and happiness, sometimes frustration when it comes to science.

"Sure!" You eagerly respond scooting closer to him careful not to bump into him.

"You'll just have to observe, knucklehead. I'll tell you what I'm feeling when you saw me acting weird or something." Senku replied scooting back a little.

You always wanted to understand and more and more.

What if you chew more than you can eat?

For a few days nothing happened. Senku was still acting the same science enthusiast that he was. That until one day, Ginro decided to be a little handsy with you. Intruding into your personal bubble.

As you were about to ask him to remove his hand that was clenching yours. Intending to drag you over the village to teach some of the children. Ginro was using this excuse to touch you.

Senku stepped in. Ginro with his experience in fighting felt danger crawled up to his spine as he hurriedly let you go and stepped back. Just in time to avoid a burning steel that was going to hit him.

"Woah. Don't run around while we're working here." Senku said raising the steel higher causing the blonde to gulp in nervousness.

"Sorry Senku, I was taking (Y/n) to teach some of the children on the village." He immediately exclaimed stepping back a little.

"Ah I see, Sorry but I actually need her with doing something here. Maybe later." Senku replied putting the molded steel back to its place.

Ginro only nodded in response. He was afraid of Senku at that moment. Something in his eyes were frightening to look at.

After the blonde went away you hurriedly go over to Senku to asked him what was that uncharacteristic behavior he displayed.

"Senku, what was that just now?" You asked staring at him hoping for an answer.

"It was nothing." He replied turning away to head towards the observatory. You instantly followed him.

"That wasn't nothing! You could've injured Ginrou by waving that burning steel!" You pressed as Senku gave a pensive look.

"Why bother about him? He was hurting you." He blankly replied turning around to face you.

Good thing everyone was busy at the village while Kiseki and Chrome was working a little far away.

You looked at him confused at what he said before he gestured your hand.

It was forming a bruise.

Taking a look back at the scientist, you released a quiet gasp at his expression. He was glaring at the bruise.

"Senku.. Can you tell me what were you thinking back then when you saw us?" You cautiously asked taking a step back.

A gut feeling of something developing for the worse is taking form within you. And it was about this scientist before you.

"He shouldn't be touching you." He replied still glaring at your hand.

"Then why didn't you asked him to let go? Instead of swinging that steel before him?" You continued to ask.

"I'm sure he could've dodge that. 10 billion percent. He has years of experience in fighting after all." The scientist before you replied scoffing as he turned his back to head up the observatory.

Senku is incredibly a capable man of science. But if he ever decided to go against his morals he can be the most frightening man in this stone world.

His intelligence is wonderful at the same time dangerous.

Looking back, (Y/n) notice that he hasn't done anything dangerous to his peers before not unless they get a little to close for your liking.

He even done it to Taiju! When the gentle giant gave you a hug when you said you'll cheer for him with his confession. Senku gave him gasoline for christ sake.

"If he was the one who petrified the whole world before i wouldn't be surprised." You muttered to yourself bringing a hand up to run over your hair.

Alone in his observatory. Senku has found out this annoying feelings that he had for you.

It was Obsession.

The urge to keep you all to himself and himself only. This world doesn't deserve you. He was finding a way for him to have you.

Senku thought of manipulation was the best way of taking you as his but the problem was Gen. Scowling at the thought he groaned outloud as he brings his hand up to his aching head.

A way to keep you to himself.

How can he do something like that in this stone world? Maybe back in the modern world he can pull off something like that.

Senku blinked at this and had his realization.

That's right! Back in modernization, when he rebuilds this world and gets the tools that he needs. He'll just invent something to erase memories of you inside the people's mind or something more convenient.

Getting his hands bloodied is not convenient after all.

And maybe a place where he alone can admire you.

You were the moon he was longing to reach. As others can only gaze from earth, he'll set out to space to reach you.

And from within his grasp you'll stay. Whether you like it or not.

You'll be his for the taking.

The only enemy he has was his own patience.
