The sixth day passed smoothly.

After bathing, finishing dinner, and eating fruit for post-dinner dessert—night finally arrived.

The moment had come.

In the lantern-lit room, my heart was pounding so hard it felt like it would burst from sheer tension.

I sat on the bed, waiting for that moment.

"Sō-kun."

A voice called from outside the room.

"Ah... ah, yeah."

In response to me answering, the door slowly opened, and Chiya walked in wearing her school uniform.

"Y-Your uniform?"

"There's no boy who doesn't like school uniforms."

When it came to hitting my weak spots exactly where they hurt, there was probably no one better than Chiya.

Apparently, she knew everything about my perverted tendencies.

She didn't recoil in horror; instead, she proactively tried to fulfill them, which was part of what made her so kind.

"Y-Yeah, I guess so."

Since there was no use denying it, I nodded.

"Then, shall we... do it right away?"

Chiya sat down beside me and said that.

I noticed my mouth had gone strangely dry.

He must be incredibly tense.

But he steeled himself and opened his mouth.

"Ch-Chiyu. Before anything else, there's something I want to say."

"Since it's our first time, 'vitality enhancement' would be a bother. It would tear me apart."

"I'm not asking for such a thing."

I couldn't help but snap at her retort.

But thanks to that, the tension in my shoulders relaxed just enough.

"Then... what?"

Her blue eyes, illuminated by the faint light, gazed up at me.

I stared directly into those eyes, so beautiful they threatened to swallow me whole.

"On the first day... you told me to say it after we got back to Earth. But if I'm going to do this, I think I should tell you beforehand."

The first day. When we were alone together in the hut.

I had tried to convey my feelings to her, but I held back.

"...!"

Childhood friends since kindergarten.

She looked as beautiful as a doll, but with few expressions and a monotonous voice, she was often mistaken for being cold.

But the real Chiyu is gentle, fond of jokes, and a magnanimous person.

"I've been in love with you ever since kindergarten."

Chiyu widened her eyes at my confession. After a moment passed, her cheeks flushed—and she smiled. "I know. I feel the same way."

The pounding of my heart, which had raced painfully fast, the strange sweat on my skin, the tingling in my fingertips, the tension that made my face burn like fire—all of it felt rewarded.

Without either of us deciding to, we shared a kiss. Just the touch of our lips meeting.

And with just that, a sense of happiness filled my brain.

Chiyu’s eyes were glistening with moisture, reflecting the lantern light until they sparkled like a clear sky full of stars.

Right now, the girl before me was no longer just a childhood friend; she had become my lover.

"Liar. I’m the one who likes you more. I’ve liked you since the moment we were born."

"No, we met back in kindergarten."

"Destiny."

"W-well... I suppose if Chiyu says so, it might be true."

It would be ill-mannered to say I didn’t believe in such things.

Amidst a series of tentative, probing kisses, our hands gradually began to find their way onto each other's bodies.

Wrapping my arms around her back as the passion of our kissing intensified, I ran my hands over her hips and thighs.

Chiyu skillfully undid the buttons of my school uniform while letting her lips trail down to my neck and chest.

"Mm...

Sayaku-kun, did you get your body tone up or something?" she asked with a look of surprise.

"Ah, I suppose that's what it looks like? It's been happening since after the event..."

We continued our conversation without stopping the touching.

"...It shouldn't be possible to suddenly become slender and muscular, no matter how hard you try."

"I wouldn't call me 'muscular' exactly, but..."

The useless fat had vanished from my once-average build, revealing a hint of muscle underneath.

My body was becoming what looked like the first step toward a lean, muscular physique.

"...Ah."

"What's wrong?"

"Could it be due to 'Strength Enhancement'?"

Her words made perfect sense to me. "Ah... That must be it."

While under the effects of Chiyu's enhancement magic, I had been practicing running alongside Mashiro.

Furthermore, even during the events, I kept running while constantly receiving buffs and healing.

The amount of movement was incalculable.

Sure, moving quickly had its benefits, but it didn't increase my stamina, so it was incredibly exhausting.

I just forced myself to keep moving by crudely curing that pain and fatigue with healing magic.

My body must have been conditioned well from being used so hard.

"A 'Muscle Strength Enhancement' training regimen?"

"If that's the case, we should probably keep doing it going forward. On an island like this, there's no harm in honing our raw physical abilities."

Besides, we have more than enough food to replenish the energy we've expended.

"Souda, if your belly gets ridges like a chocolate bar, you'll definitely become even more popular."

"No way... with the current number of people here, that's already too many, so..."

"Since our class has twenty-three girls, there is a possibility it could increase."

I'm surprised you remember something like that...

The only thing I remember is that for some reason, every girl in the class happens to have huge breasts.

Of all the reasons, the biggest one—besides the class co-teacher—is Chiayu.

"Chiayu, I'm not trying to build a harem with the girls in the class, you know……?"

"I know. But it's actually working out well."

"That's true, but……"

I'm named as the party leader, but I owe a lot of that to Chiayu's behind-the-scenes efforts and everyone else's understanding.

"Besides, by now, you must have come to like the other girls too."

"Ugh……"

Given all that has happened, it's no wonder feelings developed.

They're all charming, wonderful girls.

"That's how it should be. Tell them you like them, too."

It was indeed painful to receive their affection while feeling unable to return it.

"Are you really okay with this, Chiayu?"

"Mm. I like everyone. Besides—Sō-kun is destined to be at my side in the end."

"……Hah. I guess so, fate and all that."

"Exactly."

I and Chiyu exchanged another kiss, and I gently pressed her back onto the bed.

When I undid the top half of the buttons on her uniform, her dual mounds flashed briefly in the open air, revealing she wasn't wearing a bra.

Melding our lips together as if to devour each other, Chiyu reached for my zipper with her small hands.

I extended my right hand toward her lower abdomen... and then I realized.

"W-wait, you're not wearing any down there either?"

"Fwuh. Mnn, th-think about it... n, did you want me to take them off?"

"......Let's save that for next time."

"Copy that."

We continued to entangle each other, stoking our mutual arousal, when the wet sounds emanating from Chiyu's private parts gradually grew louder.

I pulled my hand away and looked at my fingers; they were wet.

"Sa... Sa-kun... I think we're... okay to go now."

Her face was, naturally, bright red as well.

For some reason, that made her incredibly endearing to me.

"I-I see. Then... um, shall we start..."

"Mm. Give me the one I've wanted the most."

Why on earth does he say it in such a lewd way?

Or maybe he's doing it specifically to stoke my arousal.

I hurriedly pulled down my pants, positioning myself to mount the rod pointed at the sky.

I placed a 'condom' within reach.

Tomorrow is the day of the Wisdom Wheel (Echi-ai).

The sixth day passed smoothly as well.

After bathing, having dinner, eating fruit for dessert, and then—night. Finally, the time had come.

In the room lit by a lantern, I was in a state of intense tension, my heart feeling like it was about to explode.

Sitting on the bed, I waited for the moment. "Sousuke." A voice came from outside the room. "Ah, yeah."

I answered, and the door slowly opened, revealing Chiyu in her uniform. "Y-Your uniform?"

"I don't think there's a boy who doesn't like the school uniform."

When it comes to hitting my buttons, no one can beat Chiyu.

After all, she seems to know everything about my sexual preferences.

Instead of backing off, she actively tries to fulfill my desires, which is one of her kind traits. "Y-Yeah, I guess."

There was no point in denying it, so I nodded. "Then, shall we...start?"

Chiyu sat down next to me and said that.

I felt my mouth go dry for some reason.

That's how tense she must be. But she musters her courage and opens her mouth.

"Chi, Chiayu. There's something I want to say before that."

"Since it's the first time, I don't want 'Erectile Strength Enhancement.' It'll tear." "I wouldn't ask for that."

I couldn't help but make a comment.

But thanks to that, I relaxed a bit. "So... what is it?"

Her blue eyes, illuminated by a faint light, looked up at me.

I stared directly into those eyes, which were so beautiful they could swallow me whole.

"On the first day... I mean, when you said you'd go back to Earth. But if we're going to do this, I think I should tell you first."

On the first day. When we were alone in the cabin.

I tried to tell her my feelings, but I put it off. "...!"

She's been my childhood friend since kindergarten.

She has a doll-like beautiful appearance, but because she lacks expression and has a monotonous voice, she's often mistaken for being cold.

But in reality, she was kind, playful, and had a generous heart.

"I've liked you since kindergarten."

Chiyu stared at me with wide eyes, blushed, and then smiled. "I know. I feel the same way."

It felt like everything I had been feeling – the racing heart, the strange sweat, the tingling in my fingertips, the burning tension in my face – had all been worth it.

We kissed. Just a simple touch of lips.

And that was enough to fill my mind with happiness.

Chiyu's eyes were glistening, reflecting the lantern's light like a sky full of stars.

Now, the girl in front of me was not just a childhood friend, but my girlfriend.

"No, I was born liking you." "No, we met in kindergarten."

"Fate."

"Well, if you say so, Chiyu."

It would be rude to say I didn't believe in such things.

We kissed each other a few times, and gradually our hands started to reach for each other's bodies.

I wrapped my hands around her back, and as the kissing grew more intense, I started to stroke her buttocks and thighs.

While skillfully unbuttoning my uniform, Chiyo moved her lips down my neck and chest.

"Hmm... Sou-kun, do you feel like your body's getting tighter?" She asked curiously.

"Oh, you think so? I've felt that way since after the event..."

We continued talking without stopping our touching.

"...There's no way I'd suddenly become a lean and muscular guy."

"I'm not that muscular, but..."

From just being average, I've lost some excess fat and started to show some muscle.

I've taken my first step toward becoming a lean and muscular guy. "...Ah." "What's wrong?" "Could it be the 'Enhanced Strength' spell...?"

Her words made sense to me. "Ah... I think that's it."

I had practiced running alongside Mashiro while under the effects of Chiyo's strengthening spell.

Moreover, even during events, I had been running continuously while receiving constant enhancement and recovery. The amount of exercise was immeasurable.

In fact, while it was good that I could move quickly, my stamina did not increase, so it was extremely exhausting.

I had to keep moving despite the pain and fatigue, healing it with healing magic.

My body must have been trained from being pushed to the limit.

"Was it 'Strength Enhancement' training?"

"If so, it might be a good idea to continue doing it. On an island like this, it's better to train your natural physical abilities."

Besides, we have enough food to replenish the energy we consume.

"If Sō-kun's stomach splits open like a chocolate bar, he'll become even more popular."

"No, no... Even with the current number of people, it's already too many, so there's no way that would happen..."

"Our class has twenty-three girls, so there's a possibility that the number could increase."

You really do remember such things...

The only thing I remember is that all the girls in my class have big breasts for some reason.

The biggest one is Senyuu, except for the vice homeroom teacher.

"Senyuu, I'm not trying to build a harem with the girls in our class..."

"I know, but it's actually working out well."

"That's true, but..."

Although I'm supposed to be the leader of the party, it's largely supported by Senyuu's connections and everyone's understanding.

"And besides, I've come to like the others too by now." "Ugh..."

It's inevitable for feelings to develop after all that's happened.

Everyone is attractive and wonderful girls.

"That's good. Tell the others you like them too."

Indeed, it was painful not to be able to return the affection I was receiving. "Is Senyuu really that good?"

"Mm. I like everyone too. And--Soku-kun, you're going to end up by my side anyway."

"...Heh. So it's fate." "Exactly."

I kissed Chiyo again and gently pushed her down on the bed.

I undid the top half of her school uniform buttons, and her bare breasts bounced out.

As we kissed each other hungrily, Chiyo used her small hands to rub my pants.

I reached down to her lower abdomen with my right hand… but then I realized something. "S, you're not wearing any underwear too?"

"Chu. Mm, rrr… Mm, did you want me to take them off?" "…Maybe next time." "Understood."

As we continued to arouse each other, the sound of moisture coming from Chiyo's private parts grew louder and louder.

When I looked at my fingers, they were wet.

"Sou-kun… I think it's okay to start now."

Her face was bright red.

It was somehow very endearing.

"O-Okay, let's get started then…"

"Mm. Give me the one I've wanted the most."

Why would she go out of her way to say it in a way that sounds erotic? No, maybe to get me excited.

I hurriedly pulled down my pants and prepared to cover the stick pointing toward the sky.

I placed the "condom" within reach. Tomorrow is the Wisdom Chapter.
