After school, when I got back home, I somehow ended up being forced to help my sister with her baking.

When I wondered why she’d suddenly decided to make sweets, it turned out she was planning to give them to someone she liked.

Seeing my sister do something that cute was completely unexpected. I’d never seen her act like that in my original world. Still, if it was for someone of the same sex, I supposed it would be easier to give her.

It wasn’t even Valentine’s Day, so why chocolate? I did think that—but, well… chocolate is good no matter when you eat it.

“Your hands stopped!”

“I’m helping, so don’t complain.”

“Just keep stirring!”

I kept mixing the melted chocolate and other ingredients in the bowl endlessly, until it started to develop a glossy sheen.

That was when—

My phone vibrated.

I hardly ever got messages. For a moment I thought it might be Kokonoe, but the name on the screen was unexpected.

“…Asuka?”

I’d never imagined getting a message from Asuka, and my heart skipped a beat.

But the message displayed on the screen didn’t make any sense.

“‘Help’…? What is this?”

“Hey, Kazuto. Come on, stir—”

“Nee-chan, be quiet for a second!”

“What did you say!?”

Ignoring the suspicious stare from beside me, I focused on the message.

Asuka had said she wouldn’t message me, so why was she messaging me now…?

And then, a bad feeling crossed my mind.

“‘Help me’…? That can’t be what it says… right?”

A chill ran down my back.

On Kokonoe’s advice, Asuka had decided not to go to the tea party.

But if something unexpected had happened, leaving Asuka with no choice but to go—

“…!”

I flung off my apron and dashed for the front door, still in my shirt, not even bothering to put on my blazer.

“Hey, Kazuto!? Where are you going!?”

“Sorry, now’s not the time for chocolate!”

“Whaaaat!?”

My sister’s shriek came flying after me, but there was only one thing that mattered right now.

If I didn’t go, Asuka might be in danger—

That was why I ran to the school at full speed.

◇◇◇

“Oh my… yours are much bigger than hers.”

“…Y-you saw Otomi-san’s…?”

Having removed her uniform and now dressed only in her underwear, Touka sat restlessly on the bed.

Onikisu let her gaze slide slowly over Touka’s body, starting from her toes.

“Fufu. We’d just finished undressing her when you arrived. So we didn’t do anything.”

In truth, she had tasted and savored things with her fingertips, but by Onikisu’s standards, that apparently counted as doing nothing.

“So then—when will you take off your underwear?”

“Th-that’s…”

(Th-this is too embarrassing… If it were going to happen anyway, I wish Fukase-kun were the one seeing me… touching me…)

Touka wrapped her arms around her chest and, with trembling fingers, reached for the clasp of her bra.

Steadying her breathing, she slowly unfastened it as if bracing herself, then gently placed it on the bed.

“Fufufu… ah, that’s nice… but those arms are in the way.”

“T-this is…!”

Still covering herself with her arms, Touka found she couldn’t bring herself to cross that final line.

“Then—I’ll just have to remove them for you.”

“No, ahh…!”

Onikisu glided closer, gently touching the arms Touka was using to cover herself.

Her lips wore the unmistakable smile of a predator that would not let its prey escape.

As she slowly applied more and more pressure, a pink areola began to peek out from between Touka’s fingers—the moment she saw it, Onikisu exhaled in pure ecstasy.

But at that very moment.

“…President…President…!”

From outside the door came a muffled voice calling out to her.

“…………What is it this time?”

Being interrupted twice in a row, even the usually composed Onikisu couldn’t keep the irritation from seeping into her voice.

Still, she took a deep breath to rein herself in. Leaving Touka behind with only a curt “Wait here for a moment,” she headed toward the adjoining room.

“W-what’s going on…?”

Unable to grasp what was happening, Touka stood frozen, one hand pressed to her chest.

After a short while, unsettling noises echoed from the next room, followed by the door opening.

And the one who appeared was—a girl of such otherworldly beauty that surpassed anyone Touka had ever seen before

◇◇◇

A short time earlier.

Following Onikisu’s instructions, Makoto and Ruri carried Asuka to her classroom.

As the two of them were walking down the hallway on their way back to the student council room, it happened.

“E-excuse me… may I have a moment?”

They turned at the voice calling out from behind them, and there stood a breathtakingly beautiful girl.

Long blond hair reminiscent of sunlight, a small, well-shaped face, large eyes with long lashes.

Even the normally composed members of the student council were momentarily left speechless by her model-like appearance.

“Who… are you?”

“I’m a first-year. Um, I had some business with the student council president, and when I saw the two of you, I thought I should speak to you.”

The girl, who introduced herself as a first-year, spoke in a polite yet somehow elusive tone.

Still, something about her bothered Makoto. She had a fairly good grasp of the first-year students.

And yet—she had no memory of ever seeing this girl before.

“I see… Ruri-chan, what should we do?”

“What do you mean what should we do? It’s not possible right now. The president and the others are inside.”

“Um… actually, I’m interested in the student council. I was hoping I could come and see it just once. So… would that be okay?”

When Makoto looked to Ruri with a troubled expression, Ruri answered immediately.

Right now, the student council room had Onikisu and Touka inside. There was no way they could let her in.

“Not right now. Sorry, but you’ll have to go home. We’ll contact you another day, so tell us your class and name.”

Ruri stated it firmly.

But instead of answering, the girl slowly began to approach the two of them for some reason.

“…Who are you!?”

“My name is———”

“!? Makoto-senpai, this girl is weird!!”

“Huh—what!? Kyaa!”

The next instant.

The blond girl closed the distance at an unbelievable speed and grabbed Makoto by her uniform.

She lifted her effortlessly into the air and slammed her straight into the floor.

“W-what…!? What is this…!?”

The pain knocked the breath from Makoto’s lungs, leaving her unable to move. Meanwhile, Ruri took a guarded stance, keeping her eyes on the girl.

“I finally understand. People who hurt my friends… I really hate them.”

“…You’re connected to those girls!?”

“Does that really matter?”

“I used to do karate, you know! Someone like you—kyaaa!?”

Before Ruri could even step in, her collar was seized as well, and she too was thrown down hard onto the floor.

“Kh—what… are you…?”

“Please guide me to the student council room. I—no. Before I get truly angry.”

◇◇◇

Makoto and Ruri had both of their arms forced behind their backs and bound tightly with rope by the mysterious intruder.

Then they were hauled to their feet and shoved along toward the student council room door, where they were made to open it.

“There’s no one inside… then maybe it’s that door in the back?”

“—! President, President!! Please run, President!”

“President! N-no! Don’t come this way—!”

The next instant, Ruri and Makoto raised their voices to their limit.

With no other way to warn her of the danger, they could only shout desperately.

“What… honestly, being interrupted this much is starting to make me ang—hold on. What is going on here?”

When Onikisu opened the door and stepped inside, she froze at the sight of Makoto and Ruri bound and sprawled on the floor, while a beautiful girl stood before them.

Her beauty was flawless enough to perfectly match Onikisu’s tastes—but that was hardly the issue right now.

“So you’re the president.”

“Y-you…! Do you really think you can do something like this to them and get away with it!?”

Onikisu shot her a sharp glare and stepped forward.

But by the time Ruri shouted, “Don’t come any closer!”, it was already too late.

“—Huh?”

In an instant, her field of vision flipped, ceiling and floor swapping places.

And before she knew it, Onikisu too had been slammed down and pinned against the ground.

“I know. Kokonoe-san is next door, isn’t she?”

“Y-you…!”

The beautiful girl calmly took a cord from her chest—no, a necktie—and bound Onikisu’s arms with it.

After confirming that all three of them were completely immobilized, she headed for the adjoining room.

“—It’s all right now.”

“Eh… who are you?”

“Please put your uniform back on. Kazu—Fukase-kun and Otomi-san are waiting.”

“I-I don’t really understand what’s going on, but… thank you so much for helping me!”

Touka didn’t understand why she had been saved, but she hurriedly put her uniform back on as she was told.

Bowing repeatedly, she returned to the adjoining room, and then—

“Kyah!?”

Seeing the three student council members lying on the floor, tied up, she let out a loud scream.

“I-I’m so sorry!”

Apologizing without really knowing why, Touka avoided the three of them and hurried out of the student council room.

“…Phew. I’m glad I made it just in time. This outfit was meant to make you let your guard down, and it took a while to prepare. But you really did fall for it.”

Looking down at the three tied up figures, the beautiful girl exhaled calmly.

Overwhelming strength that didn’t match her slender frame—there was only one reason for it.

“Come to think of it, I never mentioned it. My older sister has a black belt in judo. She used to practice on me all the time at home… so this was my first time using it in a real situation, but it worked out pretty well.”

“Boku…?”

The three of them felt something off about that phrasing.

Onikisu, in particular, couldn’t ignore how the beautiful girl referred to herself.

“Y-yeah! Show us your true identity! What do you think you’re doing to us—!”

As Makoto and Ruri shouted, the beautiful girl slowly raised a hand to her head and grabbed hold of her golden hair.

“—Fufu, did you know? Compared to girls together… it’s so much more pleasurable with men.”

As she murmured that, the beautiful girl removed her blond wig, letting it fall softly to the floor.
