My Gift Is “Beauty”. I Think It’s Useless, but It Seems to Be an S-Rank Gift With the Strongest Buff Effect for Beautiful Girls - Chapter 6: Hibiki’s Sister

Chapter 6: Hibiki’s Sister

“Yo! It’s been a while since I came here!”

When Hibiki opened the door, standing there was a woman with long blonde hair reaching down to her waist. She was slightly taller than Hibiki and had a more mature appearance. However, she was wearing a school uniform—in other words, she was a high school student.

“Wha—!? Mizuki-nee!?”

Hibiki called out the woman’s name, her eyes widening in shock. In response, the woman, Mizuki, smiled.

“I’m coming in~!”

“Hold on a sec—!”

“Hm? What’s wrong?”

Mizuki tried to step inside smoothly, but Hibiki stretched out her arm to stop her.

Normally, it wouldn’t be a problem to let her in, but—

(Not right now. Hiroyo is here… I have to send her home today. Besides… I was planning to do something with Hiroyo soon.)

“What’s the big deal~? Your cute big sis just came here to spoil her adorable little sister—hmm?”

“W-what…?”

Mizuki tried to slip past Hibiki’s block, but she suddenly stopped as if she had noticed something.

She leaned in close, staring at Hibiki’s face as if she were licking it with her eyes.

“Mizuki-nee…?”

“Hey, Hibiki—haven’t you gotten super pretty!?”

She blurted out something almost identical to what Hibiki’s classmates had said earlier.

Hibiki let out a small sigh of relief.

“My friends said that too. I’ve been working hard on skincare and dieting. That’s why—”

“My skill is reacting.”

“Huh?”

Hibiki’s heart nearly stopped.

For a moment, she thought Mizuki had somehow figured out that Hiroyo had used a skill on her.

But something was off. As far as Hibiki knew, Mizuki didn’t have any skills like that…

“I recently learned a new skill—’Magic Vision.’ It lets me see the traces of magic left behind after someone uses a skill, as well as the flow of magic when it’s activated. And right now, your body—your face—is glowing a little. …Actually, your whole body?”

The last time Hiroyo had used a skill on her was a few days ago.

Normally, any magical traces should have faded by now. That’s how skills worked.

(Wait… could it be that the effect just kicked in today?)

The moment she actually felt the effects of Hiroyo’s skill was this morning.

If that was the case, wouldn’t that mean the skill had technically just activated?

“…Well, whatever. If my cute little sister is getting prettier, then I’m happy too. Anyway, I’m coming in~!”

“Ah—! Nooo!?”

Mizuki took advantage of a brief moment of distraction and slipped into the entrance.

The first thing that caught her eye was the two pairs of loafers left by the door.

One pair was Hibiki’s.

The other was obviously not a woman’s—it was a much larger size.

“Oh, crap…”

Seeing what Mizuki was looking at, Hibiki accidentally let those words slip out.

That might have been the final nail in the coffin. Mizuki turned back toward her with a wicked grin.

“Hibiki’s got a guuuuy~!!”

“That’s not—!”

Like a dancer at a party, Mizuki jumped excitedly and stormed into the house.

She flung open the door to the living room, but no one was there.

She peeked behind the sofa just in case, then immediately stepped into the hallway and headed for the stairs.

“Hey! Mizuki-nee! Stop!”

“I need to see what kind of guy my dear Hibiki is dating.”

“He’s not my boyfriend—!”

“‘Not yet’ your boyfriend, huh?”

“Ugh, stop that! Just go home for today…!”

At the bottom of the stairs, they grabbed each other’s arms and pushed back and forth.

But no matter how hard she tried, Hibiki couldn’t win against Mizuki in strength.

“Just give up already?”

“Oww oww oww!?”

Hibiki lost easily, and Mizuki dashed up the stairs.

She reached Hibiki’s room and, without hesitation, threw open the door.

“—Huh!?”

Sitting at the table was Hiroyo.

His eyes widened in surprise at the sudden appearance of an unfamiliar blonde woman.

On the other hand, Mizuki stared intently at Hiroyo, as if evaluating him.

“So, you’re the one… Kinda mature-looking for Hibiki’s taste.”

“Hey! Mizuki-nee! Don’t just barge in like that!”

Hibiki arrived late and tried to pull Mizuki out of the room. She failed.

“Um… who is this?”

“I’m Hosaka Mizuki—Hibiki’s big sis! …Well, technically her cousin. But we’ve been together since we were little, so we’re basically real sisters!”

“I-I see… I’m Takanashi Hiroyo.”

After Mizuki introduced herself, Hiroyo gave her a slight nod.

Ignoring Hibiki’s protests, Mizuki plopped herself down at the table.

“N-no… This isn’t how it was supposed to be…”

She couldn’t stop her with force. Giving up, Hibiki entered the room and sat down at the table.

Then, she blinked at Hiroyo.

(Hiroyo, please.)

(Huh? What do you mean?)

(Don’t say anything weird.)

(I have no idea what you’re talking about…)

Hibiki winked to tell Hiroyo not to say anything unnecessary, but of course, he didn’t get the message.

“Hmm… Hiroyo-kun, what’s your relationship with Hibiki?”

“Uh… We’re just normal classmates.”

“I know that already~ Are you Hibiki’s boyfriend?”

“Ah… No, I’m not.”

She had asked Hibiki earlier, but now she was asking Hiroyo. His answer was the same as Hibiki’s.

“Hmm…”

“U-uhm…!”

From the moment Hiroyo first saw Mizuki, there was something he wanted to ask her. After all, this wasn’t the first time he had seen her.

“Hosaka Mizuki… Are you from Tenchi Guild…?”

She looked exactly like someone he had seen on TV many times. Not only that, but her name was the same. So, he forced the words out through his trembling throat.

“Hm? Yeah, that’s me. Oh, do you know me? I’m so happy~!”

Hiroyo’s guess was correct. Mizuki smiled brightly and looked delighted.

She wasn’t someone he admired back when he wanted to be an adventurer. But lately, she had been a hot topic. In fact, anyone who followed adventurer-related news would know who she was. It was only natural that Hiroyo did too.

“Uh… yeah. You’re famous, after all.”

“Hiroyo… I never told you. I’m sorry.”

“No, it’s okay.”

Hibiki knew that Hiroyo once dreamed of becoming an adventurer. She also knew it was something he struggled with. That’s why she never brought up the fact that she had a relative who was one.

Besides, since Mizuki was an A-rank adventurer in Tenchi Guild, Hiroyo might have looked up to her. She didn’t want to hurt him, so she kept quiet.

“Hmm… So, Hiroyo-kun, you wanted to be an adventurer?”

“Yes, but—”

“You didn’t get a combat skill.”

“That’s right.”

Even though he didn’t say everything, Mizuki figured it out.

She had been acting cheerful, but now, sensing Hiroyo’s feelings, she lowered her voice slightly.

“Hey, isn’t it about time you left? Just go home already.”

“Hibiki, you’ve never said that to me before… How cruel!”

“The cruel one is you, Mizuki-nee, for barging in uninvited!”

“Okay, okay, I get it. Hibiki looooves Hiroyo-kun.”

“W-what the hell are you saying, you idiot!? There’s no way I like Hiroyo! …Ah.”

Mizuki teased her, and in the heat of the moment, Hibiki blurted out something she didn’t mean.

Hiroyo gave her a wry smile. Hibiki saw that and hurriedly corrected herself.

“H-Hiroyo, that’s not it! I just got caught up in the moment—anyway, it’s not true!”

“Thanks. I already understand.”

“Did I take it too far? Oh well, I’ll go home for today.”

“Ughhh, just leave already!”

Hibiki made Mizuki stand up and pushed her out of the room.

She pressed against Mizuki’s back, forcing her down the stairs toward the front door.

“I totally get it now. Hibiki loves Hiroyo-kun.”

“Ugh… You can come over anytime when Hiroyo isn’t here, but don’t ever do something like this again!”

“Yeah, yeah. See you later~!”

“…Bye.”

Hibiki didn’t dislike Mizuki. In fact, she liked her.

When she wanted to improve her appearance, Mizuki was the one she went to for advice. That’s why she was grateful to her and wanted to stay close.

But she hated being teased about Hiroyo.

“Hiroyo… I’m really sorry about earlier. Let me apologize properly.”

“I already told you it’s fine. Don’t worry about it.”

“But, you see—”

She apologized again for her thoughtless words.

Unlike before, her face was now clouded with regret.

Seeing that, Hiroyo wrapped his arms around her.

He usually wasn’t the one to act first, but this time, he couldn’t just stand by. He had to do something.

“Want me to use my skill today too? Just a little should help you feel better.”

“…Idiot. You’re not supposed to use it just because of dirty thoughts.”

“You’re the one who jumped me last time because of it.”

“Ahh, geez… You really are an idiot, Hiroyo…”

While exchanging those words, they naturally made their way to the bed.

And once again, their hands moved to each other’s clothes, slowly undressing.

Halfway through, their eyes met. This time, they wanted to do it properly. Their faces drew closer, and then—

“Ahhh! Sorry, sorry! I forgot my phone—whoa. Hibiki, you go hard~♪”

Just before their lips touched.

With a loud bang, Mizuki burst into the room.

On the bed, both of them were half-dressed, holding each other’s waists.

Anyone could tell what was about to happen.

“………..”

Hiroyo and Hibiki turned their eyes to Mizuki.

And at the exact same moment—

“Aaaaahhhhhhhhhhhhhh!?”

“Gyaaaaaaaaaaaaaahhhhhhh!?”

They both let out deafening screams, having been caught in the most embarrassing situation possible.
