‧₊˚ ┊ GEN ASAGIRI
In the harsh reality of the stone world, you’d been trying to hide it for weeks.
The constant stomach pain that twisted like a knife after meals or the episodes of bloody diarrhea that left you weak and embarrassed, the worst was probably the brutal fatigue that made gathering even simple resources impossible leading to Senku being a dramatic ass because he couldn’t do it himself.
But despite that, Senku, the observant scientist, finally pulled you aside after noticing all those pattern during a village meeting.
And after running every test his stone-age lab allowed, observing symptoms, analysis of the whole body, and questioning you thoroughly, he delivered the diagnosis.
Crohn’s disease. After hours of explanation of the disease that looked more like an explanation given to a child who understands nothing, you learned that it was your body’s defense system that gets confused and starts attacking your own digestive tract like it’s an enemy. Making you painfully sores and big swelling inside your gut because food doesn’t get absorbed well.
Therefore you get lots of pain, and it can cause dangerous problems later if not handled. It is chronic after all, but Senku said they could manage it step by step.
He himself outlined a plan for you, you are as important as anyone in the kingdom of science, he was not going to leave his friend without medicine even in this stone world (gen would have harassed him otherwise) so anti-inflammatory herbs would be cultivate, with also a strict dietary controls to avoid triggers, and a rest protocols while the world would walk toward better medicines as hopefully science improves soon.
He was blunt but hopeful in his typical “this is just a problem to solve” way.
Gen was right there when Senku explained it all. The mentalist’s even tried using jokes.
”Ah, so now my partner has been secretly hoarding all the soft leaves for their tummy troubles? Very sneaky indeed~”—
but it quickly died in his throat with his smile faltered completely and his eyes filling with rare but genuine sadness while the weight of it hit him. After Senku left to start researching remedies, Gen wrapped his arms around you tightly, burying his face in your hair.
“I’m sorry,” he whispered, voice thick.
“That was a stupid joke. I just… I hate seeing you hurting like this and pretending everything’s fine. You’ve been carrying this alone while the rest of us are out there rebuilding the world. It’s not fair.”
From that moment, Gen seemed devoted in a way that went beyond his usual playful personality. Hell he even used every mentalist tricks he possessed not for manipulation, but for comfort or distraction like he said.
During painful episodes he was talking about his stupid stories from pre-petrification days with a silly voices to make you laugh even when you felt awful.
He personally sorted through food stores to prepare safe and easy-to-digest meals, even going as far to sacrificing his own portions. Nights by the fire he’d hold you close, rubbing your back when the pain kept you awake, has he murmured reassurances.
“We’ve survived petrification, wars, and literal stone age nonsense. This sneaky gut rebellion doesn’t stand a chance against Team Senku… and especially not against my incredible partner.”
He let himself feel the sadness openly with you—admitting how helpless it made him feel but always followed it with hope.
“Senku’s a genius. And I’m a master of the heart and mind. Between us, we’ll keep you smiling and strong.”
Gen’s comfort was the best, it was emotional, tender and always constant. Because he made sure you never felt like a burden.
It felt like the diagnosis brought you even closer, with his love showing in the way he chose to stay present through every hard day, proving that even in the stone world you had someone who would fight for your peace of mind with everything he had.
‧₊˚ ┊ UKYO SAIONJI
(reader is in the army with ukyo in this one)
Several symptoms have been emerging for some time now…
At first it was easy to dismiss because it looked like symptoms that anybody could have, such as morning stiffness in your fingers, a deep fatigue that couldn’t stop even while sleeping, and these angry red patches on your skin.
Then the swelling started.
Your knees would get even bigger and hotter after hard training and the pain was so bad that you had to limp….
But you couldn’t let this slow you down. You kept going because that is what you do in the navy. You thought it would pass after a while. Maybe the training was too intense and you developed those symptoms… or maybe a simple vacation would be good??
But one day a superior noticed and ordered full tests. Honestly who are you to disagree against a superior? Wouldn’t want to take the risk to lose your job…
And unfortunately the diagnosis wasnt positive, it was Rheumatoid Arthritis. From what you understand it was an autoimmune disease. Your body’s immune system attacks the lining of your joints just by mistake and this causes painful swelling and inflammation leading to permanent damage over time, for instance hearts issues. To summarize it, it’s like your own body attacking itself. It’s great… just great.
And to add cherry on the cake this chronic illness lasts for life. But luckyfor you modern medicine can manage it with special drugs or physical therapy.
The doctor said your career did not have to end, but your life wouldn’t be the same anymore..
When Ukyo learned that an superior asked for a test, he immediately decided to accompagne you, so he waited outside the medical bay when you came out. He was still in his clean uniform with his body straight but his eyes looked soft with worry.
At first you expected a whole worried Ukyo but he actually did not ask many questions… just the name of your ilness, you felt grateful at this moment. He just walked beside you back to the barracks with his presence that felt like a quiet anchor to you.
For a few days none of you talked about it, until one evening he came to your room with a thick folder he made himself.
It had research papers on RA for people still working. There were so many lists of safe medicines that would not affect work and he even added diet tips to lower swelling and easy exercises to keep your strength without making symptoms worse.
“I called in some favors,”
He rubbed the back of his neck.
“I talked to people in medical who handled similar cases. I will not let this get to you.”
And when you broke down and said you were scared of becoming a burden to the team and to him, he didn’t hesitate to pull you into his arms even if it was carefully so he wouldn’t hurt you.
“You are not a burden. You are one of the best peoples I have ever served with. More than that, you are the person I trust most. The one I love…This is just another obstacle. We adapt. We fix problems. We overcome. That is what we do.”
Over the next weeks, Ukyo became your rock in every way. He changed training schedules so you could do easier exercice (he ask to spotted you himself) In the mornings he would bring warm compresses for your hands before shooting practice. In the evenings he sat with you during bad moments and most of the time you would sit there in silence. He wanted to remind you that strength means keeping going and that if you didn’t had the strength in you, he would give you some of his.
Late one night after a very rough day, he held you close on his bunk with his fingers gently traced patterns on your arm.
“I chose this life with you in it… The diagnosis does not change that. We have each other’s back through every mission, every flare, every challenge. Ten years from now we will look back and see how we turned this into another story of strength.”
And eventually he turned the scary diagnosis into something you could face together, one careful step at a time.
‧₊˚ ┊ RYUSUI NANAMI
Extreme fatigue, frequent lung infections, salty skin, and digestive problems had been annoying you for a while now.
Ryusui, with his ridiculous wealth and resources, had forced you to accept his help with the absolute best specialists flown in from everywhere.
The diagnosis was simple, Cystic Fibrosis. It’s a genetic problem you are born with, your body makes thick and sticky mucus instead of normal thin one. And those mucus clogs up your lungs and digestion system like sticky glue in pipes. And those causes infections, breathing trouble, and problems absorbing food.
At first Ryusui did not just accept it. He attacked it with full energy.
“The best doctors in the world are now your doctors!”
he declares with that booming laugh, though his eyes show real worry underneath his bravery attempt to reassure you.
He bought special treatments, got experimental medicines, and kept top specialists on call 24/7. He even changed parts of his yachts and houses to make everything easier and cleaner for you.
One day he pulls you onto his yacht, away from everything, and holds you close.
“Money can buy almost anything,”
”happy you know that Ryusui…”
“Let me finish my treasure, Money is great, but it can’t buy more time with you. So I’ll use every yen, every connection, every resource on this planet to give us as much time as possible.”
In fact, Ryusui doesn’t change a lot.. he is still continuing to spoils you rotten but just a different kind of spoiling now. With much more comfort or custom nutrition plans from world-class chefs, hell he even get the softest clothes that don’t irritate your skin, and that only so you can still enjoy yourself without thinking of this chronic illness.
And when you feel like a burden, he laughs it off.
“Nonsense! A captain takes care of his crew… and you are my most important crew member.”
His energy was simply big and positive. And eventually he turned the scary diagnosis into a challenge he was determined to win with you..
‧₊˚ ┊ KOHAKU
One day you suddenly had moments of muscle weakness. You fainted more often and sometimes without warning, your heart would beat too fast or weird and leave you pale and shaky.
You thought that maybe it was kohaku that was making you this effect.. after all she was so beautiful, but no, you understand it wasn’t just kohaku making you feel love when you suddenly faint one day after your heart had beat too fast with Hyoga next to you. And let me tell you that it was frightening…
Senku did careful checks and tests after this issue. And unfortunately diagnosed a heart condition. He explained it slowly so that you and Kohaku could understand it more easily, it was your heart acting like a drum that sometimes beats at the wrong rhythm or too fast. This can make you feel weak or pass out.
He tried to compared it a little to Ruri’s old sickness so that kohaku could understand how this sickness was to take seriously but still said it was different and they would handle it.
Yet Kohaku still got very scared when she heard that. Her face went pale and her fists clenched tight.
Because yes Kohaku can be terrified. She’s pale, fists clenched, eyes wide with fear.
“You’re… you’re not going to end up like my sister was, right? Before Senku saved her?”
Her voice even cracked after saying this. She’s seen what illness can do in this world, and the thought of losing you to something invisible wrecks her.
Once Senku assures her he has a plan and leaves to work on remedies, Kohaku becomes your fierce shadow. She’s not great with the science but she’s incredible with protection and emotional support.
She carries you when you’re weak, hunts extra food for strength, and stands guard when you rest.
“I won’t let anything take you,”
And from the way she says it, you can say it’s like a promise she made to herself.
“Senku fixed Ruri. He will help you too. And until then, I’ll be right here.”
She trains a little less aggressively so she can stay close, tells you stories of her village adventures to distract you, and holds your hand tightly during bad episodes. Her fear slowly turns into determined hope.
“You’re strong too. We’ll fight this together—like warriors.”
Her comfort is physical, loyal, and deeply emotional—she shows love through action and unwavering presence, scared but refusing to let that fear win.
