I was Thrown into an Unfamiliar Manga

"Sorry! Did I keep you waiting?"
At the sound of that voice, we all turned our heads at once.

And what unfolded before us could only be described as a scene out of a man's ideal fantasy.
Boobs, wall, boobs, boobs, boobs.

Five girls who had changed into swimsuits were walking toward us in a row.
First was Sasha.
With long limbs like a model’s, Sasha wore a black competitive swimsuit with an open-back design.

The tight fit emphasized every curve of her body, stealing the attention of all the guys around.
Next was Karen.
Like Rika, she was in a bikini, but hers leaned toward a cute, frilly style.

Apparently embarrassed to show so much skin, she’d thrown on a white hoodie over her pink frill bikini.
Third came Rika.
With her mother Maria’s blood flowing strong, Rika had the textbook Western figure.

All the right curves in all the right places—her cola-bottle body was not something you saw every day.
Even in her uniform, her prominent chest always stood out, but now in a green string bikini, her huge bust looked like it might go berserk at any moment.
Fourth was the class rep.

Wearing a white bikini that highlighted her neat and pure look.
Her usual twin braids were tied into a single thick braid, and instead of glasses, she had contact lenses in, exposing her bare face.
Honestly, it was jarring.

In my head, the class rep always wore glasses.
That didn’t mean she wasn’t pretty, though.
In fact, she was pretty in a very normal, pleasant way.
Lastly, Yaguchi.

True to her title as the class's bust queen, her checkered swimsuit and short shorts barely contained a violent figure that could only be described as “dynamite.”
The green headband she always wore was gone, probably because it would get wet, and apparently that had been sealing her beauty all along.
Now with her brown hair tied back with a hairband instead, her pale nape was exposed—an area that rarely saw the sun, making it appear especially white.

Gulp—
Someone swallowed hard.
For a hormonally-charged male high schooler, this scene was practically poison.

Even Ryuji, who normally acted like a wooden statue, was blushing—proving again that our group really did have above-average looks.
Of the five girls who’d swarmed us, the first to speak was Sasha.
"What do you think, Kim Yu-seong? Of my perfect body?"

She struck various model-like poses as she spoke. And honestly, with that body, it was downright provocative.
"I-I’m not gonna lose either!"
Not to be outdone, Rika—former reader model—crossed her arms under her chest and struck a sexy pose.

Unlike her usual ditzy image, the serious expression she wore now gave off an exotic vibe.
Watching the two of them, Karen went "Kuh—" and covered her chest with her hands.
…Sorry for calling you a wall. You’re not flat-flat. Just… petite.

In any case, I knew what those two were waiting to hear, so I nodded and said:
"You’re both beautiful."
And just like that, their faces relaxed into wide grins.

Apparently, complimenting a woman’s looks is the correct answer in any situation.
Meanwhile, Yaguchi, who was shyly trying to appeal to Ryuji, wasn’t quite as bold as the other two. With a slight blush on her face, she asked:
"How do I look?"

Ryuji looked around nervously before replying.
"Uh, yeah. It suits you."
"…Thanks."

Blushing, Yaguchi lowered her head.
It was a textbook scene of youthful romance.
Watching all of this unfold in real time, Satoru shouted:

"Normies explode! No, die!!"
Sorry, Satoru.
This one’s on you for being unpopular.

***
Thanks to Satoru rampaging from jealousy, there was a brief disturbance—but we soon left the guesthouse and headed straight to the beach to enjoy the summer.
Since it was both close to Tokyo and vacation season, Onjuku Beach was packed with people.

It was, quite literally, a sea of people.
Scantily clad hotties were soaking up the brilliance of youth.
And Satoru, who had fully snapped, declared that even if it killed him, he was going to get a girlfriend this summer—and promptly left the group to go girl-hunting.

His energy was so intense that Ryuji and I couldn’t bring ourselves to stop him.
He’d probably be back by lunchtime, whatever happened.
We borrowed a parasol from Yaguchi’s cousin and stuck it into the sand, then laid down a rubber mat underneath and piled our bags on top.

Honestly, our bags just contained drinks, water, and some cash.
We’d left everything else back at the guesthouse, so we weren’t too worried about losing anything.
"We’re planning to play beach volleyball now. What about you guys?"

At that, I looked around at our group.
There were originally eight of us, so we could’ve split into two even teams. But thanks to Satoru running off to hunt, we were down to seven.
That meant a 3:4 split, and no matter which side I joined, it would mess with the balance.

So, holding back my tears, I waved them off.
"I’ll watch ✧ NоvеIight ✧ (Original source) the stuff. Honestly, if I joined, it’d be unfair."
A 3-on-3 match would be more balanced.

Ryuji was a worthy opponent who could match me, but the other team had Sasha and Karen—both strong, athletic types—so it wouldn’t be an easy fight.
"You sure? I mean, we came all the way to the beach…"
"It’s fine, really. Or Ryuji can switch out after a game and I’ll join."

Maybe because I sounded convincing, the girls nodded and split up into teams to start the beach volleyball match.
Sitting in the perfect spot with a great view, I happily watched the ball bounce on the mat as the match began.
***

"Karen, it’s coming!"
"Yeah! Leave it to me!"
"Nice! Score one for me while you’re at it!"

As expected, Sasha and Karen had perfect coordination.
They bickered all the time, but when it came to teamwork, they were in perfect sync.
Sasha would receive and set, and Karen would spike—targeting the weak spot: the class rep.

To be fair, Rika’s team had a weak link too, but even so, Rika was more athletic than the completely hopeless class rep.
It was close—neither side had much of an edge. But in the end, Ryuji’s team lost with a final score of 13:15.
Ryuji admitted defeat with grace and declared he’d go buy ice cream for everyone.

The girls offered to come too, but he insisted that, as a man, he’d handle it himself.
Thanks to that, the remaining five of us took a break under the parasol while Ryuji went to get ice cream at the beach hut.
The beach volleyball court was a decent distance away, so I couldn’t hear what they were saying—but judging by the laughter, they were having fun.

I sat under the parasol watching them with a pleased smile.
That’s when I noticed them.
Two bleach-blond, tanned punks—straight out of a textbook illustration of Japanese delinquents—were approaching our group of girls.

***
"Yo-ho~★ Spotted some cutie-pie babes!"
"…Senpai, don’t you think it’s about time to drop that tone? Honestly, it’s embarrassing to be seen with you."

"Shut up. It’s not like I enjoy it either. It’s just trendy in our scene right now, so I’m playing along."
"That trend’s been dead for years."
"Yeah, whatever."

The one called “senpai” grumbled and took off his sunglasses, placing them on top of his head.
Now he looked just like your average blond, tanned beach punk—no more, no less.
"I’m into that blonde over there. You?"

"I like the redhead."
"…Didn’t know you were into that."
"Wait, no! Don’t get the wrong idea! It’s just… my first girlfriend was flat-chested, so I think I’ve been conditioned or something!"

"Sure, let’s go with that."
"I’m serious!!"
The two chatted idly, lost in their fantasies.

If things went well, this summer might not be so lonely after all…
"Hold it."
"Huh?"

A low, heavy voice suddenly echoed from behind them, and both guys turned their heads.
Standing there… was a monster.
A muscle-bound beast who looked like he could snap a human spine in half with ease.

Clearly sensing this guy wasn’t just some ordinary tourist, the blond punk tried to resolve the situation with words.
"U-um, is there a reason you’re speaking to us…?"
His tone was unexpectedly polite—very unlike his usual cocky attitude.

And rightly so. The moment their eyes met, he realized.
The man standing before them wasn’t just different. He was a whole other species of alpha male.
Looking down on the two, the muscle giant said:

"Leave. While I’m being nice."
Just one sentence. But it had a force that couldn’t be denied.
"Y-yes, sir! Thank you for the warning!"

The tanned blond punk bowed repeatedly, then turned on his heel and walked away with his companion.
Kim Yu-seong, having protected the peace of five girls all on his own, proudly returned to the parasol where he had been sitting.
