Volume 13 Chapter 460 Shirogane Kanon, Aqua-sensei Who Can’t Hold Back!!
Edited by: Kanaa-senpai
Ugh… why did it have to turn out like this…?
While I was turning red from embarrassment, Aqua emerged from the changing room, having finished getting dressed.
”Sorry to keep you waiting, everyone.”
Aqua, wearing a white shirt over his swim trunks, flashed us a big smile that seemed to light up the whole beach.
KYAAAA! He’s so cool!!!
The three of us—me, Ayana-chan, and Claire—were totally drawn in by the glimpse of his toned chest and navel visible through the open shirt.
Seriously, Aqua has absolutely no sense of shame…
Normally, a guy would wear a swimsuit that covers his upper body—like Toa-chan does—but Aqua doesn’t care about that kind of common sense.
I didn’t know since I transferred in midway, but when Ayana-chan told me Aqua had always been like this, I was absolutely speechless.
”Alright! Time for roll call!”
Aqua blew the whistle he had in his mouth.
Oh no, oh no, oh no! I was getting way too excited at “Aqua-sensei.”
Back in the day, there was this slightly naughty legendary shoujo manga called “Naughty Leo-sensei!”—and I wondered if the Leo-sensei from that story would have looked like this.
I’d heard that at the time, the National Diet even got into heated debates about “unrealistic depictions of teenagers” and the “danger of accelerating the author’s delusions”—the comic’s “non-reality” sparked major controversy in this country. The fallout reached even overseas, and “Stars” banned it outright as a forbidden text, restricting both its sale and import. But for some reason, Grandmother had a complete collection in her library.
”First, we’ll warm up! Do it properly so nobody gets hurt. I’m watching all of you, got it?!”
We started stretching as instructed. Aqua, with his serious expression and whistle still in his mouth, kept a watchful eye over our warm-up routine with an intense gaze.
Ugh… Aqua, if you stare at us that much, we get embarrassed too!
There was a scene like that in the manga too—I could totally understand why the students would misunderstand Leo-sensei’s serious gaze and confess their feelings, even though he was just paying attention to their stretches.
”Tsukimachi! Your body’s too stiff. Stretch like this!!”
”Huh? Ah… okay…”
Whaaaat?!
Aqua pressed his body against Ayana-chan’s back and wrapped one arm around her waist. Caught off guard when his hand brushed her side, Ayana-chan’s face turned beet red.
I get it! I totally get it, Ayana-chan!
Even if he’s the guy you like, as a girl, there are some places you absolutely don’t want touched!
But Aqua didn’t care about any of that. He grabbed Ayana-chan’s hand with his other hand and guided her through the stretch.
”See, like this. One-and-two, one-and-two…”
Hawa-wa-wa-wa-wa-wa!
It’s just like that scene where Leo-sensei gets too into his teaching and presses up against a student to demonstrate directly!!
”Ugh…”
Ayana-chan’s entire body flushed red as she repeated the side-bending exercise—the kind you do in radio calisthenics. Every time she moved, I could swear Aqua’s face got closer to Ayana-chan’s exposed armpit. Was that just my imagination?
Come to think of it, maybe there was a service scene like that in Leo-sensei too.
While Aqua was distracted by Ayana-chan, I leaned over and whispered to Claire, who was nearby.
”Claire… this is…”
”Yes, no doubt about it. This is exactly the Leo-sensei who became a girl’s bible. Look over there, Kanon-san.”
I followed Claire’s subtle gesture with my eyes.
And there—holding up a camera in a school swimsuit—was Emily-senpai, capturing everything on video.
UGHHH! If you were coming anyway, at least bring my swimsuit too!!
Emily-senpai noticed my glare and proudly showed off her own school swimsuit.
Um… and? What’s that supposed to mean?
Emily-senpai flashed me a cue card:
[I wore the school swimsuit I had back in junior high so you girls don’t have to suffer alone!!]
No, that doesn’t matter at all!!
I opened and closed my mouth like a fish before mouthing at Emily-senpai: “Stop doing useless things!”
But Emily-senpai, misinterpreting completely, scratched the back of her head with an embarrassed look.
She was probably thinking, “Hey, cut it out. You’re making me blush!” and mistook my complaint for praise.
Honestly! Aqua and Emily-senpai both always twist everything in whatever positive direction suits them best!
”Kanon-san, you mustn’t take Emily-san seriously.”
”Ah, right…”
I gave a small nod at Claire’s words. The light had completely vanished from her eyes.
”Alright! Good work, Tsukimachi! You did great!”
”Ah… yes.”
Freed from the humiliation play, Ayana-chan looked relieved. Aqua ran his pen over the sheet clipped to the clipboard Yamamoto-sensei had handed him.
”Tsukimachi Ayana… armpit sweat, armpit smell, armpit eroticism. Double circles for all of them…”
Excuse me?! What kind of evaluation is that?!
Ayana-chan covered her bright red face with both hands and shook her twin tails side to side in embarrassment. Seeing that, I immediately hugged Ayana-chan and gently comforted her.
Come on, Claire-san, you too…
”Humiliation play from Aqua-sensei… I’m so jeal…”
Ah… no good. This is hopeless…
I remembered that Claire-san, who I’d thought was my ally, was actually an executive of that weird religion.
”Hey, you two were spacing out and didn’t do any warm-up at all. Come on, Kanon. Forward and backward bends!”
”Y-yes.”
I slowly bent forward as Aqua-sensei instructed.
Aqua-sensei crouched in front of me and stared at me with a serious face.
Aqua… he’s really watching me…
Being famous for how easy I am, that alone was enough to make my body heat up.
Wait, nooooooooo!
Aqua isn’t watching me. He’s staring straight at my cleavage while I’m bent forward. Honestly!!
”Oof… Your b**bs look like they’re about to spill out of that school swimsuit. This is dangerous. I’ll have to give you proper remedial lessons later…!”
Hm…? Did he say something?
When I looked toward Aqua, he was staring at my cleavage with a serious face.
Huh? Was that my imagination?
I felt like he said something incredibly fast just now… Well, if it was my imagination, then that’s fine.
I put my hands on my waist, then bent my upper body way back.
”This is bad! Kanon’s b**bs are being crushed by the school swimsuit and spilling out from the sides! I need to hold them in place with my hands!!”
Wait, Aqua?!
Even Leo-sensei never had a scene that blatant!!
Aqua supported my b**bs from the sides.
”It’s okay, Kanon. Sensei will make sure this doesn’t become indecent by supporting your b**bs from the sides so they don’t spill out!!”
”Y-yes…”
Honestly! Honestly! What even is this play?!
Even as I blushed, I kept doing the warm-up.
Then, when I bent backward, I saw Emily-senpai in the corner of my vision taking pictures of me with a camera fitted with an ultra-long telephoto lens.
Come to think of it, I saw Emily-senpai chugging park water recently. It wasn’t because she bought that lens, right?
Once I somehow endured the embarrassment and finished the warm-up, Aqua ran his pen over the paper on his clipboard again.
”Let’s see, Shirogane Kanon. Breast development, firmness, side-boob eroticism. Double circles…”
I told you we don’t need that kind of pointless grading!!
With tears in my eyes, I puffed out my cheeks and trembled in little shakes.
”Aqua-sensei. Please guide me as well.”
”Yeah! Leave it to me!!”
Aqua turned his head toward Claire-san’s voice and froze instantly.
Wait a second. Claire-san?!
Claire-san started twisting her body from side to side.
Hawawawawawa!
When Claire-san twisted sideways, the V-shaped swimsuit floated up, making the shape of her breasts completely visible.
Not only that, through the gap in the lifted swimsuit, even a girl’s most important place was completely exposed.
”Sensei…? Will you not guide me?”
”Huh? Ah, yeah. Sorry, sorry.”
That Aqua was completely behind when dealing with Claire-san.
”Sensei. My swimsuit is moving and seems like it might slip out of place, so could you hold it firmly for me?”
”O-okay…”
Aqua-sensei moved behind Claire-san and firmly grabbed the two long strips of fabric between her breasts and lower abdomen with both hands.
After confirming that, Claire-san started the same twisting exercise as before.
”Nn.”
Claire-san let out a sultry voice and blushed slightly.
H-hey… what happened? What’s going on?
Claire-san twisted in the opposite direction and trembled in tiny shudders.
Ah… Ayana-chan and I looked at each other as we realized why Claire-san was reacting.
”I-is that…”
”Yeah. It’s rubbing, isn’t it…”
Because the excited Aqua was gripping the swimsuit tightly, every time Claire-san twisted her body, the swimsuit rubbed against her n**ples and her important place.
Each time Claire-san let out that sensual voice, Aqua put even more strength into his hands, and the swimsuit fabric gradually twisted into cord-like strips.
”Nn.”
U-uwah…
The cord-like swimsuit teased her n**ples left and right. Wait, she’s completely exposed now!!
Is this okay?! I looked toward Emily-senpai, who was filming us from far away.
Then Emily-senpai pointed a cue card at me.
[You two! Look at Claire’s lower abdomen!! It’s gotten even crazier!!]
Huh?! Ayana-chan and I looked at each other, then turned our eyes toward Claire-san’s lower abdomen.
The swimsuit had become rod-like and was digging into her slit.
Wait?! Is this okay?!
I looked toward Emily-senpai again.
[No problem! Keep going! I mean, there’s no way someone like me could stop Claire once she goes wild!!]
Emily-senpai wore a sharp, calm look as she wrote down something really merciless.
Yeah… I’m definitely not relying on Emily-senpai.
”Hah… hah… Aqua-sensei, how was my… warm-up?”
”Perfect score, obviously!”
Aqua-sensei’s pen flew across the paper clipped to his clipboard.
”Lewdness, pervertedness, shamelessness—all double circles!”1
Oh. Uh. Right. Sure.
Aqua-sensei looks happy, so me and Ayana-chan are happy too… I guess?
”Alright! Time to swim! Oh, Kanon—you just got discharged, so start with walking.”
”Okay, got it.”
I stepped into the pool and started walking slowly.
Aqua-sensei’s gaze drifted toward my breasts floating on the water.
”Shirogane Kanon… bonus points… and good. Keep it up! Do your best!”
Hey. What exactly are those bonus points for?
I shot him a deadpan glare. Sensing my eyes on him, Aqua-sensei quickly looked away from my chest.
”Uff.”
Aqua-sensei’s mouth fell wide open, and he froze, eyes bulging.
Now what?! What happened?!
I turned to follow his gaze.
And there was Claire-san, swimming freestyle—completely naked.
Wait, WHAT?! Claire-san, where’s your swimsuit?!
From across the pool, Emily-senpai held up a cue card.
[Kanon! Look at the starting point!]
I turned my gaze to the starting point.
And there, floating on the water, was Claire-san’s swimsuit.
Ah… it came off when she dove in…
”A naked pool… this is… actually acceptable…”
IT IS NOT!
Aqua-sensei! I am NEVER swimming naked!
I covered my body with both hands and turned my face away from Aqua-sensei, whose eyes were almost sparkling with hope.
”Tch. No good after all. In that case!”
Aqua-sensei tore off his shirt and dove into the pool, sliding into Ayana-chan’s lane.
Ayana-chan stopped swimming and stood in front of him.
”Ayana. You’re not great at freestyle, are you?”
”Uh, yeah. I can swim, but… I’m not really that good at it.”
Aqua-sensei moved behind Ayana-chan, pressing close to her back.
”First, this is the basic arm movement.”
”Oh, okay.”
Huh. He’s actually giving proper instruction—
Wait! Don’t think I didn’t notice you using the chaos to check out Ayana-chan’s armpits again! Honestly!
I raised my arm and glanced at my own armpit.
W-what’s so great about this place anyway…? It’s just an armpit.
Emily-senpai’s cue card flickered at the edge of my vision.
Yeah, yeah. Read the cue card. I turned my eyes to it.
[Pretend it’s an accident and press your armpit against Aqua-sama’s face! Aqua-sama loves sweaty girls’ armpit-flavored salt onigiri2 more than three meals of white rice!]
I AM NOT DOING THAT! HONESTLY!
Also, I did NOT need to know that last part.
”Next, leg movement goes like this.”
Aqua-sensei handed Ayana-chan a kickboard and instructed her to lie face-down as if floating in the sea.
”Ayana… you have beautiful legs…”
Naturally praised by Aqua-sensei, Ayana-chan dunked her face in the water to cool her tomato-red cheeks.
Yeah. I get it. That’s just unfair, isn’t it?
Compared to that, I’d rather he just get excited about dumb stuff like armpits and b**bs.
”This is the correct flutter kick motion. Now, try swimming like this for a bit.”
”O-okay. Got it.”
Wow, amazing. Her form is way cleaner than before.
I clapped soundlessly.
”Keep swimming while the feeling’s fresh.”
”Okay!”
Ayana-chan started swimming freestyle.
Yeah, way faster than before.
Leo-sensei was serious but useless, but Aqua-sensei is a pervert AND competent…
Claire-san, who’d been watching from the next lane, stopped swimming and approached Aqua-sensei.
”Aqua-sensei! Do you have any instruction for me?!”
The fully nude Claire-san’s eyes sparkled.
”Uh… Claire-san. First, let’s put your swimsuit back on…”
”Hweh?! Ah… I-I’m sorry! This isn’t what I meant!”
Claire-san scrambled to retrieve her floating swimsuit.
Uh… if this isn’t what you meant, then what exactly did you mean when you decided to wear it? I wanted to ask, but it was too scary, so I didn’t.
Claire-san put her swimsuit back on underwater.
”Well then, please teach me!”
”Alright, freestyle’s too intense, so let’s go with breaststroke.”
Aqua-sensei started teaching Claire-san breaststroke.
Hmmmm.
It looks like he’s teaching seriously, but did he really need to dive underwater and check her swimsuit ride-up from behind while teaching leg movements?
Also, he was definitely staring into her cleavage while teaching arm movements.
I see right through you!
”Okay, I’ll try on my own now. Aqua-sensei, please watch from there.”
”Sure!”
Claire-san started swimming breaststroke alone.
The moment she did, her swimsuit floated up to the surface.
Ah. Yeah. Of course. I kind of figured.
”(Gurgle) (Damn), (gurgle gurgle) (totally visible)…”
Hey, Aqua-sensei. What exactly are you doing underwater?
And if you drown this time, I’m NOT saving you! Honestly!
I turned away from Aqua-sensei, whose nose was almost stretching across his face, and resumed my walking with determination.
Huff… huff… I guess going to space really did a number on my stamina.
I decided to call it quits and started climbing out of the pool.
The moment I did—my leg cramped.
”Ah—”
I reached for the ladder, but my hand caught nothing but air.
Crap. I’m gonna drown at this rate!
Just as that thought crossed my mind, Aqua-sensei—who’d been further away—turned his face toward me.
”KANOOOOOOOOOOOOOOOOON!”
Aqua-sensei dove underwater and shot toward me in seconds using the Prime Minister’s legendary Kaiten-style swimming technique.
”You okay, Kanon?!”
He wrapped his arms around me, his face full of concern.
A-amazing… Not even that legendary manga [Can’t Do It. Leo-sensei] had a scene this cool!
”Ah, yeah… I’m fine. Thanks.”
I pushed down my racing heart and looked up at Aqua-sensei.
Ughh… Aqua-sensei is just way too cool.
He said before that he’s “a fine figure of a man dripping with water,”3 and now I finally get what he meant.
I thanked him, feeling shy.
”Kanon. You’re still recovering. Don’t push yourself too hard when I’m not around.”
”Th-then… when you ARE around…?”
At my words, Aqua-sensei flashed a grin with his white teeth.
”I’ll save you with everything I’ve got! No worries!”
Ugh! Ugh! Aqua-sensei always says stuff like that!
This isn’t me being easy4—this is definitely Aqua-sensei’s fault!
Emily-senpai’s cue card flickered in my vision. Fine, fine! I’ll look!
[Kudos on being easy! …is what I’d say, but that one was unavoidable. Also, I totally recorded that scene, so we can all watch it later. Guhehe!]
Ugh…!
Well, if that’s how it is, maybe I’ll forgive you for switching my swimsuit to a middle school-era school swimsuit!
Ayana-chan and Claire-san, nearby, stared at me intently.
”Isn’t this just Emily-san’s setup…?”
”That’s why they call Kanon-san easy.”
Hm? Did you two just say something?
Probably just my imagination.
Oh well…
”Alright, make sure to disinfect before changing.”
”Okay~”
The three of us finished our exercise and entered the changing room.
There, all three of our panties were laid out neatly, crotches exposed.
”Dirt, smell, taste…”
”All double circles, apparently…”
UGGGGGGGGGGGGGGGGGGGGGGGGGGGHHHHHHHHHH!
Aqua-sensei, you idiot idiot idiot!
Hmph! I’m not talking to you for the rest of the day—well, that’s too much for me, so until I get home! Honestly!
===
Emily: “Should I start calling her ‘Claire-san’ too?”
Claire: “Emily-san… if you call me with ‘-san,’ I’ll actually get angry, you know?”
Emily: “Eep?! Dear readers, have you noticed? This is the TRUE power balance of the Holy Aqua-sama Church!”
Incidentally, here’s what the three of them were wearing:
Kanon: White panties with lace frills.
Ayana-chan: Grey cotton sport panties with black trim.
Claire-san: Black panties with a see-through design.

Summary:
The swimsuit lesson begins with Aqua leading warm-up exercises, immediately escalating into physical contact with Ayana that leaves everyone flustered. Kanon draws parallels between Aqua’s behavior and the legendary “Naughty Leo-sensei” manga, while Emiri documents everything on video from the sidelines. Claire shifts the dynamic by deliberately positioning herself for Aqua’s attention, creating an even more risqué situation that leaves Kanon and Ayana stunned.
Kanon reflects on Emily-senpai’s merciless note-taking before Aqua arrives to lead a poolside training session. The group engages in swimming instruction that quickly devolves into comedic chaos involving accidental nudity and perverted observations. Kanon nearly drowns from a leg cramp but is dramatically rescued by Aqua, leading to an emotional moment that she immediately undercuts with self-deprecating humor.

Translation Notes:
Notes:
• Aqua – A world-famous idol, BERYL leader, tokusatsu actor, and sharp-eyed student. Wielding past-life wisdom, this accepting yet reckless and oblivious male lead is deeply treasured by his crew for saving Shintaro and destroying a meteorite. Now discharged after a long hospital stay following a space collision, he remains the object of affection for Yukari, Inko, Maron, and others.
• Claire – Student and friend to the group. Has a calculating, performative personality. Deliberately orchestrates situations to get physical attention from Aqua. Secretly has particular interests as a high-ranking member of a “weird religion.” Uses her body intentionally to fluster Aqua.
• Ayana – Student and friend to Kanon and Claire. Has a pure, easily embarrassed personality. Becomes flustered when Aqua physically assists her with stretching. Has twin-tailed hair.
• Toa – A male BERYL idol, livestreamer, and AI interface who uses broadcasts for space communication. Formerly a shut-in, this “cute-cool” companion has an upgraded luxury wardrobe. He shares a deep bond with classmate Aqua, acting as his straight man and following his lead; as a perceptive group member, he sees through Aqua’s act immediately and gives deadpan stares.
• Kanon – Internet master, fashion icon, and Verification Team member Kanon-sama is Aqua’s devoted, jealous wife and Kotono’s sister. Famed for her elegant appearances, this underage, chunibyo youngest sister hides her emotions behind a cool, easily flustered exterior. Heavily sleep-deprived, she roasts her friends but often falls victim to Emily’s schemes, recently blushing and refusing to talk to her after an indirect kiss.
• Emily – Heavily pregnant and graceful, Saint Emily is the Yukishiro heir, a church official, and high-academic Verification Team junior. Friend to Kanon and others, she is married to Shirogane Aqua, whose child she expects, Kukuri’s “oneechan,” and close to Hakuryuu-sensei. A scheming, exaggerated trickster and “Impression King,” she uses a “guhehe” laugh and once posted Kanon’s indirect kiss video online.
• Yamamoto – Teacher who handed the clipboard to Aqua for the roll call and evaluation session.
