The return to the Kingdom of Science is anything but quiet.
The Medusa device—humanity’s most dangerous miracle—rests secured in layers of insulation and stone, carried like a sleeping god back into the heart of the village. The war is over. The world has survived itself. Again.
For the first time in a long while, there is no immediate crisis demanding Senku Ishigami’s voice.
The villagers cheer. Children run alongside the path. Chrome argues excitedly about future experiments. Kohaku laughs. Gen pretends not to cry. Tsukasa watches the crowd with careful eyes, relieved but wary.
And Taiju—ever the same—grins wide as he helps unload supplies.
That’s when he sees her.
A familiar stone figure, wrapped carefully in cloth, carried with reverence rather than urgency.
Taiju stops dead.
“…No way,” he breathes. “Senku. Isn’t that—?”
Senku doesn’t answer right away.
Because it is her.
The class representative.
The girl who kept their classroom from falling apart before the world ever did. The one who scolded loud boys into silence, who organized chaos into order, who listened when Senku rambled about science instead of telling him to shut up.
The one he noticed—quietly, privately—before the day everything turned to stone.
Taiju explains later. How they found her statue intact. How she was preserved well. How it just… felt right.
“She was always helping people,” Taiju says, voice soft. “Figured the kids in the new world could use someone like her.”
No one expects what happens next.
Senku doesn’t call a meeting.
Doesn’t ask for help.
Doesn’t delegate.
He goes straight to the lab.
For three days, he barely sleeps.
He calculates, recalculates, adjusts formulas down to fractions no one else can track. Chrome tries to assist—gets waved off. Gen offers to help negotiate materials—ignored. Even Tsukasa tells him to rest.
Senku doesn’t.
No one has ever seen him work like this.
Not during the stone wars. Not during the Medusa conflict. Not even when rebuilding civilization itself.
There is a sharpness to his movements. An urgency that doesn’t come from logic alone.
By the time the revival fluid is complete, his hands are shaking.
He doesn’t let anyone else pour it.
The moment her eyes open—confusion, fear, breath rushing back into lungs that haven’t worked in millennia—Senku is there.
Explaining.
Calm. Clear. Gentle in a way only she will ever see.
The stone world. The years lost. The kingdom rebuilt. Why she was chosen.
And when she asks what she’s meant to do now, still dazed, still grounding herself in reality—
“You teach,” Senku says, immediately. “Same as before.”
She becomes the village’s teacher.
The children adore her. The elders trust her. The Kingdom of Science grows not just smarter—but kinder.
And somehow, naturally, she comes to live in Senku’s house.
“It’s efficient,” he tells them. “I invent. She teaches. Knowledge transfer is faster that way.”
No one believes him.
A year passes.
The village thrives.
And something in Senku begins to… change.
He catches himself staring while she teaches.
Listening when she laughs.
Timing his meals to hers.
Standing too close.
Fixing things she hasn’t complained about yet.
He doesn’t understand it at first. Tries to quantify it. Tries to reason it away.
Until one night, staring out over the village lights, Taiju nudges him with a grin.
“You like her, don’t you?”
Senku scoffs. Gen smirks. Tsukasa watches quietly.
“I don’t waste time on distractions,” Senku mutters.
Tsukasa answers calmly. “Then why do you look calmer when she’s around?”
The thought sticks.
And for the first time in his life, Senku Ishigami allows himself to consider something terrifying.
That even he— Even the man rebuilding the world— Might want love.
Tonight, the Kingdom of Science hums softly under the stars.
Inside the house, lamplight spills across stone floors and scattered notes.
Senku stands at the worktable, pretending to focus.
Failing.
Because she’s here.
Living with him. Teaching beside him. Existing in his future in a way he never calculated for.
