Volume 13 Chapter 453 Shirogane Aqua, Overprotective
Edited by: Kanaa-senpai
Thanks to everyone, I miraculously woke up. For a full day, I was in the ICU undergoing a series of tests.
”Fufu, good morning. Aqua-kun, you’re awake?”
”Ah, yes. Good morning.”
The soft-spoken nurse who looked after me in the ICU, Momoshiro Kaho-san, smiled warmly at me. When I first woke up in this world, she was also my assigned nurse. I realize now—the ‘Shiro’ in her name means she’s from the same Yukishiro branch family as me.
”Sorry about all the tests. But from now on, you’ll be in a private room, and you can see everyone again, so you won’t be lonely.”
”Ah, yes. Thank you for taking care of me.”
Kaho-san drew the room’s curtains, then peeled back my blanket.
”Well then… let’s pull it out.”
Pull it out?! Kaho-san, what do you mean by pull it out?!
With the heart of a young boy, my own heart raced wildly.
Kaho-san lifted my hospital gown, then slowly reached toward my lower abdomen.
U-ooooooh!?
The embarrassment made me turn my face away slightly. As I did, the nurse’s uniform-clad chest pressed against my back—her generous figure making contact.
”It’s o~kay. Big sister’s already wiped your body while you were sleeping. I know every inch of your body.”
Kaho-san whispered sweetly in my ear, her warm breath sending a shiver.
”So, you don’t need to be embarrassed… There, all do~ne. You couldn’t even tell, could you?”
Kaho-san, having removed the catheter, smiled brightly.
Oh, really. I really couldn’t tell she’d pulled it out. She’s good, this woman… Wait—no, that’s not it! “Pull it out” meant THAT?!
I wished Inko-san were here.
Sob, sob. My healthy high school boy libido had just been toyed with.
As I wept internally, Kaho-san whispered in my ear.
”Aqua-kun. If you’ve got a buildup, big sister can help you out with that too. Fufu, if you ever need to go to the toilet with big sister, just say the word. Or… do you want to go right now?”
Urgh… I’m certain of it now. Emily.
Emily was really worried, but it’s not just me and Emily who are weird.
Yui’s also a distant relative of the Yukishiro, so it’s just the Yukishiro bloodline being plain horny.
So it’s not me or Emily’s fault! That’s what I’m going with, okay?!
”Um, well then…”
”Ah, sorry. Aqua-kun… I actually have plans after this. I’ll see you later.”
Dammit! But if she’s got plans, nothing I can do.
I got into the wheelchair Kaho-san had prepared.
”Now then, off to your private room.”
”Thank you.”
Kaho-san pushed the wheelchair, taking me to the private room. Honestly, I’d have preferred a four-person room with the rest of BERYL, but since I just woke up, they said I’d be in a private room for now.
When Kaho-san and I entered my hospital room, someone was already sitting on the sofa.
”And… here we—huh? Kohina-san?”
”Kohina-senpai, do you need something?”
I’m trying to spend quality time with my hot nurse big sister Kaho-san here, so please don’t interrupt.
”Thanks. I’ll take it from here.”
Saying that, Kohina-senpai shoved Kaho-san’s back, pushing her out of the room.
”Eh? Ah… Aqua-kun. If anything happens, press the nurse call button.”
Nooo… My Kaho-san! My busty, slightly naughty older nurse big sister!!
I felt like pressing the nurse call button right away to call for help. Because I already had a bad feeling about this.
Kohina-senpai turned to face me, her large eyes fixed on my face.
”Did you eat lunch properly?”
”No, not yet…”
Kohina-senpai wheeled me over to the bed, helping me lie down.
Crap… I’d lost that much strength and muscle? This was going to take a while before I was back in action.
Kohina-senpai left the room and came back with a tray of food.
”Here. I brought you some rice porridge.”
”Ah, thank you.”
Kohina-senpai being… nice?!
This was definitely a sign I was about to get scolded.
Having known Kohina-senpai for a long time, I figured it out in seconds.
Despite the pain in my body, I willed myself to sit up straight.
Look, Kohina-senpai. I’m ready to be yelled at whenever you are!
Kohina-senpai sat on the round stool beside my bed, picking up the bowl of porridge.
Ah, I see. She’s going to eat it right in front of me!
And make me, starving as I am, watch her enjoy it!
Just as I was anticipating that kind of treatment, Kohina-senpai blew gently on the spoonful of porridge.
And then—rather than bringing it to her own mouth—she held it out to me?
Wait, what? Is she… testing something right now?
I felt like I was taking some kind of hunter exam.
”Here. Open up.”
”Ah, yes.”
I opened my mouth, and Kohina-senpai slowly brought the spoon to my lips.
Mmm, delicious… Even though it’s porridge, it really tastes like rice.
As someone who loves rice above all three meals, I almost teared up at the sweetness spreading through my mouth.
”Here.”
”Ahh~”
Guided by Kohina-senpai, I savored the porridge with tears in my eyes.
Rice really is the best. The moment I eat rice, I feel the most alive.
To each grain of rice, I silently prayed: “Become my flesh and blood.”
Recently there’s been a push to limit carbs and villainize rice, but the Church of Power teaches that rice-built muscles have more horsepower than any other kind.
Quality rice creates quality power.
After finishing the meal, I clenched and unclenched my fist. I felt like the rice had brought me back to about ten percent of my prime…
I was tempted to do squats carrying the hospital bed, or handstand push-ups!
”Now then. I’m going to return these dishes, but you… you just woke up, so don’t you dare do anything stupid.”
Kohina-senpai looked down at me, her glare unwavering.
I was drenched in sweat like a frog stared down by a snake.
”Ah… fay…”
How… did she know?
Deflated, I behaved myself on the bed.
Kohina-senpai returned after returning the tray.
”Thank you very much.”
”Mmn.”
Kohina-senpai sat on the sofa in the room.
Um… Is she planning to stay here instead of going back to her own room?
I kept glancing at Kohina-senpai’s face.
”What, thirsty?”
”Ah, no… not really…”
Something’s off.
Compared to the usual Kohina-senpai, her behavior was strange.
Because of that, I couldn’t treat her casually like usual, and I didn’t know how to handle it.
Whatever. Might as well go to the bathroom.
Eating made me need to pee.
I slowly sat up and tried to stand.
”What are you doing!?”
Kohina-senpai stood up from the sofa, her face pale.
Seeing her reaction, I froze.
K-Kohina-senpai, what’s wrong?
She’s definitely acting strange…
”Ah, no. I was just going to the bathroom like normal…”
”Then say so.”
Kohina-senpai helped me get up.
The help was appreciated, but isn’t she being a bit too overprotective?!
I can stand up on my own, you know!
”Hah…”
I let out a small sigh as I entered the bathroom.
Seriously, Kohina-senpai not acting like herself is throwing me completely off-balance.
Wait—EEEEEEEEH?!
”Kohina-senpai, why are you coming into the bathroom with me!?”
”What do you mean? To help, obviously. Here.”
Kohina-senpai said that, and gently grasped my important area.
Wha—wha-wha-wha-wha-WHAAT?!
”Here, I’ll support you, so… just go. Can you do it? You haven’t forgotten how, have you?”
No no no! Forgetting how to pee? That’s way too serious to be let out of the ICU!?
In my head, I started counting Nene-cho’s Great Kaiju Yukari-gon chibi design.
Great Kaiju Yukari-gon one, Great Kaiju Yukari-gon two, Great Kaiju Yukari-gon three…
”Mm, good. That’s it… you’re doing so well.”
Grrrrrgh!
The way Kohina-senpai’s words sounded so lewd—that’s definitely because I’m a healthy high school boy!
Hwhaaa~! I recited some kinda prayer in my head, just anything to focus.
Hah hah hah… O-okay, done.
I managed to empty my bladder by going full zen mode.
”Here, hold still. Let me clean that up for you.”
Kohina-senpai said that, and gently wiped me with tissue.
Well, I guess this is just… one of those things. Natural order, right?
Kohina-senpai stared at my very much awake and alert situation.
Wait, hold on! Please, let me explain! This ain’t what it looks like!!
”Of course it’s like that—you’ve been holdin’ it in so long, you can’t help it. Here.”
Kohina-senpai gave me a gentle, rhythmic stroke.
Ghhhhh—WAIT, HOLD ON?!
Hold on a second. Kohina-senpai, this ain’t something you can just laugh off!!
”Does it hurt? If you want me to go faster, just say so.”
Kohina-senpai pressed something soft against my back.
Ohhh god, ohhh god, OHHH GOD—!!
Kohina-senpai wrapped her slender fingers around me, stroking that spot under the ridge where it felt best.
Ahh, oh man—my whole body went taut before I could stop it.
”Almost there?”
I nodded frantically, again and again.
Then Kohina-senpai grabbed the paper cup beside her and wrapped it around my—
”Mm. You can let it out now.”
Ah…
My body shuddered at the pleasure I hadn’t felt in a while.
It’d been so long, I came like crazy…
”Hold on a sec.”
Kohina-senpai said that and pressed the nurse call button.
Immediately, about three doctors and five nurses came rushing into the bathroom.
H-hey, I’m completely exposed here! What kinda game is this!?
The Shirogane Department Store—known as the department store of fetishes—just got another new product added to its inventory!!
”Here. Take this. You said you wanted to run tests, right?”
”Thank you so much!!”
The doctors who received the paper cup from Kohina-senpai raised my sperm-filled cup toward the heavens as they left the room.
Hold up. Even I have limits on embarrassment, ya know!?
But… I’d thought it was strange Kohina-senpai was going this far for me… and now I understood why.
”Hold still. I’ll clean you up now.”
Kohina-senpai grabbed some toilet paper and gently wiped me clean.
”Tell me if you wanna do it again. I’ll still do it with you, tests or no tests.”
”Ah, right…”
Kohina-senpai was definitely acting weird.
Maybe another meteorite was about to crash down from space or somethin’…
With Kohina-senpai supporting me, I made my way back to my own bed.
Damn. All I did was eat a free meal and go to the bathroom, and I’m already wiped out, ya know?
The moment I closed my eyes, I must’ve fallen asleep without realizing it.
”Mmm…”
When I woke up, I saw the evening sun streaming through the window.
Already… this late, huh? I was gonna do my rehab, but I guess I slept way longer than I planned.
”Morning. Sleep well?”
Whoa!? I jumped at the sound of Kohina-senpai’s voice.
Y-y-y-you’re still here!?
”Everyone came to visit while you were asleep, you know. They all left right away, though—said it’d be a shame to wake you up.”
”Ah, thanks for handling them while I was out.”
I looked at the bedside table.
There were a bunch of things there that hadn’t been there before I fell asleep.
I spotted a sticky note on one of the sports drinks.
[Aqua . Drink this if you’re thirsty. From Kanon]
KAAAAAAAAANON! ! !
I fought back the urge to cry and looked at the magazine next to it.
[Hehehe! I bought a gravure magazine Aqua-sama would probably like. Feel free to use it when you’re alone! From your Emily! ! ]
A school swimsuit special issue… featuring busty big sisters!?
As expected of Emily. Her taste is absolutely flawless.
I was especially looking forward to the special sealed section featuring embarrassing school swimsuits on widows and married women.
I picked up the notebook beneath the magazine.
[To Shirogane. You forgot your summer homework at home, so I brought it for you. Make sure you finish it before the second term starts. 3-A Homeroom Teacher, Sugita Mari]
I nearly collapsed on the spot.
Teach… can’t you let me off the hook for that free research project where I saved Earth?
My mind flashed to Sugita-sensei’s sad face when she realized I’d forgotten my homework.
Damn it! Guess I have no choice but to do it!!
When I looked to the other side, I saw a pair of dumbbells on the table.
Ah, yeah. Even without reading the sticky note, I knew exactly who brought those…
Thanks, Kaede. And Iria-san, too.
Just as I was getting all teary-eyed from everyone’s warmth, Kohina-senpai stood up from the sofa and slowly approached.
”Dinner’s still a ways off, but is there anything you wanna do?”
”Ah—”
Come to think of it… how many days has it been since I last bathed?
My body felt all sticky, and I was thinking a hot bath would really freshen me up.
”Can I take a bath?”
”Mm. I’ll go ask—hang on.”
Kohina-senpai said that, left the room, and came back almost immediately.
”Got the key. Let’s go.”
With Kohina-senpai helping me walk, we headed to the bath area.
Finally, I could relax and be alone—WHOA!? Kohina-senpai, I can undress myself without your help!!
After she stripped me down, I covered my face with both hands out of sheer embarrassment.
Sob sob… I can never get married now!
I tried to make a joke out of it, but Kohina-senpai—what are you doing!?
Kohina-senpai took off her hospital gown, then removed her underwear and dropped it in the laundry basket.
”C’mon, we’re gettin’ in together.”
”Ah, r-right…”
Kohina-senpai poured hot water over me, then lathered up a sponge.
And just like that, she started scrubbing my back vigorously.
Hold up. She’s casually started washing my body…
Am I about to get eaten by Great Kaiju Yukari-gon or somethin’!?
After finishing my back, Kohina-senpai reached around to wash my front.
”I’ll do the front myself!!”
I snatched the sponge from Kohina-senpai and quickly scrubbed myself.
Phew, that was close. If she’d washed my important parts too thoroughly, I’d have started reactin’ again…
Once I finished washing, Kohina-senpai used the same sponge to quickly wash herself.
”Alright, I’ll wash your hair next.”
”Thank you.”
…This feels strange.
Usually I’m the one washing and drying her hair—so why is she washing mine now?
Maybe I’m still dreaming?
”Okay, rinsing the suds off now.”
Kohina-senpai used the shower to rinse the soap from my hair and body.
Then she rinsed herself off, too.
After we’d both washed up properly, Kohina-senpai and I got into the bath together.
Wait—why is Kohina-senpai behind me and I’m in front of her!?
Shouldn’t it be the other way around!?
”Here, lean back more. It’s okay.”
Whoa—! Kohina-senpai tilted me back, and her soft breasts gently cradled the back of my head.
”How’s it feel?”
”Ah, f-fine…”
Maybe I’m still dreaming after all…
For some reason, I stopped hearing the word “b**bs” in my head, but that’s gotta be it!!
Before I knew it, bedtime arrived in what felt like an instant.
”Alright, come over here. Time to sleep.”
Hold on!? Why is Kohina-senpai sleeping in my bed!?
Kohina-senpai took my confused hand and pulled me toward her.
Ahh, man! If this is a dream, then wake up already!!
Guided by Kohina-senpai, I let my head rest against the softness of her chest.
”Aqua …”
Kohina-senpai’s thin voice called out as she hugged my head tight.
”I’m so glad you’re alive…”
I could hear Kohina-senpai’s sobs.
…Damn it! So that’s how it is!!
All of this—it’s all my fault, isn’t it!?
I slowly pulled away from Kohina-senpai and gazed at her face as she lay beside me in bed.
”Kohina-senpai, I’m fine. I’m alive.”
I took Kohina-senpai’s hand and brought it to my cheek.
”Sorry for worrying you.”
”You should be sorry. You idiot…!”
Yeah, yeah. I pulled Kohina-senpai into a tight hug and gently stroked her head.
”I… I really thought… I thought you were gone, h—hic…”
I held Kohina-senpai close, nodding at her words again and again.
”I’m fine. I’m not going anywhere now.”
”Really…? You’ll stay by my side forever?”
I nodded at Kohina-senpai’s words.
”I’ll stay by your side forever. So please, don’t worry.”
”You promised. If you lie, I’ll make you swallow a thousand needles, cut off your fingers, and chase you to the ends of hell!!”
Scary as hell!
No wonder even the Devil himself runs crying from Kohina-senpai.
Definitely not gonna cross her…
”You really mean it? You’ll stay with me forever?”
”Yeah.”
”You’re not lying?”
”Yeah, yeah.”
”Like, forever and ever and ever?”
”I got it already.”
We went back and forth like that for about an hour.
I was starting to get a little annoyed, but all of this was my fault.
So I’d accept all of it willingly. Isn’t that what it means to be a man?
Maybe Kohina-senpai had just been on edge all this time, but she eventually got tired and fell asleep.
”Zzz… if you lie… I won’t forgive you… mumble mumble…”
I wiped away the tears at the corners of Kohina-senpai’s eyes and brushed a strand of hair from her face.
Kohina-senpai, I’m sorry I worried you.
I gave Kohina-senpai a light kiss on the forehead, then held her close as I drifted off to sleep.
After the awkward bathroom incident, Kohina-senpai’s strange behavior continued as she insisted on helping me with every little task, including taking a bath.

”Yukishiro” means “snow castle” and the family is known for having a horny bloodline.
Emily and Yui are both connected to Aqua through the Yukishiro bloodline.
BERYL is the group Aqua is part of, and he wanted to share a room with them.

The “Church of Power” is a parody of muscle training obsessives who treat exercise like a religion.
Kohina-senpai is normally strict and scolding but has become overprotective after Aqua’s near-death experience.
The “Hunter Exam” reference is a pop culture nod to the Hunter x Hunter series.
The protagonist previously saved Earth, as referenced in his attempt to use it as an excuse to skip homework.
Kohina-senpai’s behavior—bathing and sleeping with him—is driven by her fear of having almost lost him.
The “” markers are meta-humor written by the characters themselves, not translator notes.
Emily’s gravure magazine features a “special sealed section” with widows and married women in school swimsuits.
Kaede and Iria-san brought dumbbells for the protagonist’s rehab.
The “Shirogane Department Store” joke plays on the protagonist’s family name and its reputation as a “department store of fetishes.”
Kohina-senpai threatens the protagonist with “a thousand needles and cut-off fingers,” a Japanese idiom for severe punishment.
The Devil is referenced as someone who would run crying from Kohina-senpai, localizing the Japanese Enma reference.
The protagonist usually washes and dries Kohina-senpai’s hair, making their current role reversal significant.
Yukishiro clan is mentioned in the author’s notes as being perverted.
