I was Reincarnated as the Youngest Child of a Villainous Noble Family Who Controls the Kingdom from Behind the Scenes

"What’s this? Just another weirdo joining the party?"

Thanks to that damn sister of mine, Erik has gone full arrogant-mode again.

Not that I care, but I wish he’d at least make a proper move when it counts.

Speaking of that damn sister, Miley-neechan is staring intently at Erik and the others.

"Those kids… not bad. Not quite on Alfis’ level, but…"

"They’re all summon-bearers. Perfect research material, don’t you think?"

"I wonder what kind of demons they’ve contracted with? Let’s have a little look, shall we?"

Whistling, Miley-neechan twirls her staff in one hand and steps forward—only to be blocked by Waltamine.

"And who might you be?"

"Alfis’ sister."

"Alfis’… hmm. Didn’t expect him to have a sister like you. But trying to kiss your own brother? How indecent."

"What’s indecent about kissing my beloved little brother? You’re the one who’s messed up in the head."

Waltamine probably never expected to be called out like this by that damn sister.

The two glare at each other from point-blank range—close enough to kiss.

"Oh? So it’s because of a sister like you that Alfis is so timid. Family environment really matters, doesn’t it?"

"Alfis can get along with plenty of girls—one, two, three, even four at once."

"But he’s still a virgin, right?"

"Excuse me?"

Whoa, this conversation just took a weird turn.

Even Erik and Ios over there are making weird faces. Should I stop this?

And what’s wrong with being a virgin? Huh? Say it to my face.

"A-Alfis-sama is n-not a v-virgin!"

"You shut up. Actually, just stop talking altogether."

The gloomy angel is the most flustered one here.

The headmasters just clear their throats and pretend they’re not involved.

"Anyone can see it. But don’t worry, I’ll gladly take Alfis’ virginity for him. Giggle…"

"You? Take Alfis’?"

Miley-neechan clenches her fist and slams it into Waltamine.

"Guh—!"

Waltamine goes flying several meters before landing in a crumpled heap.

Miley-neechan balances her staff on one finger, spins it, then snaps it back into her grip.

Oh no. She’s pissed.

Actually, I’ve only seen Miley-neechan lose her temper once before—when I ate her favorite snack and tried to hide it.

Looking back, she wasn’t mad that I ate it—she was mad that I lied.

And back then, she was spinning her staff just like that.

That’s her rage signal.

"A-Agh…"

"I went easy on you, so get up. I could’ve killed you in one hit. Now—who was it that said they’d take Alfis’ virginity?"

"You damn bitch! I’ll never forgive you! HEAVY RAIN!"

Waltamine summons dark clouds, unleashing a downpour.

The raindrops cling to my body, making me feel slightly heavier.

"Her contracted demon must be Omokarisama, the Water Jizo."

"Oh? Alfis, you’re so well-informed! The longer you’re caught in this rain, the heavier your body gets until you can’t move! A god-class demon rivaling the 32 Pillars of the Demon Realm!"

Waltamine cackles, but does she even realize her rain is being gathered into a single spot?

Right above her head.

"Ohohohoho! Now, while you’re immobilized— Huh? The rain… Wh-Why is it—?!"

"Better dispel it fast, or that water sphere’s just gonna keep growing. So—who was it that said they’d take Alfis’ virginity?"

"Tch!"

Waltamine tries to cancel the spell, but the water sphere bursts—drenching her completely.

"GYAAAAAH! A-Ah… s-so heavy… I’m gonna be crushed…!"

"People say I’m a master of water magic, but the truth is—I specialize in manipulating all liquids. And yet, a tramp like you dares to claim my brother’s—"

"M-My arm… it’s shriveling… Nooo!"

"Learn some shame, you damn [REDACTED]."

She drops a word that definitely can’t be broadcasted.

Miley-neechan points her staff at Waltamine’s arm—and it withers into a mummy-like state.

Waltamine shrieks as her limp arm dangles uselessly.

"Wh-Why?!"

"The human body is mostly water, you know. Oh, and one more thing."

"GYAAAAH! IT HURTS! MY BLOOD—MY BLOOOOD!"

Blood gushes from Waltamine’s legs as if it has a will of its own, tearing through her skin.

Within seconds, she passes out.

Yeah… against Miley-neechan, most living things don’t stand a chance.

To beat her, you’d either have to escape her absurd mana control or match it to protect your own body.

Either way, I’d get obliterated in an instant.

She’s laughably strong.

"I want to kill her, but any more and she’d actually die. But this bitch had the nerve to say she’d take Alfis’ virginity… Ugh, I really wanna kill her…!"

"Enough. And stop saying ‘virgin’ so much."

Waltamine’s probably suffering from extreme anemia now.

Miley-neechan encases her body in water and tosses her outside the door.

"Let the special cleanup crew handle the rest. Right, Alfis?"

"Yeah. Hope she doesn’t die before then."

"So, Alfis—who are you giving your virginity to?"

"I said drop it."

Thanks to this damn sister, the headmasters over there are coughing awkwardly, their faces bright red.

Stop traumatizing the old men.

Luciel’s covering her face with both hands.

The fight was over in an instant—leaving everyone speechless.

Erik and Iok are completely intimidated.

"T-This is the Balfont family’s power… Lord Erik, we should retreat! We’d need the entire 7th Division to handle her!"

"Hmph. No need to panic. Have you forgotten my contracted demon?"

"B-But…"

"Are you disobeying me?"

Erik grabs Iok’s shoulder—and his skin faintly discolors.

"GYAAAH! M-My apologies!"

"Good. Never question me again. Now—let’s take them on together."

Iok stands beside Erik, facing us.

They’d live a little longer if they just gave up now.

"Alfis, your big sister’s a bit tired, so I’ll take a break."

"Yeah. Luciel, it’s just us now."

Miley-neechan’s yawning, but she’s probably just staying to watch our fight.

Not that I’d ever let her handle everything anyway.
