I Became the Younger Brother of the Villainess

“…You’ve been waiting this whole time? Really?”

Her expression brightened at the sight of me, and she nodded vigorously, as though simply seeing me leave my room had made her day.

Not long after, I spotted Daisy in the distance, clutching the hem of her long skirt as she sprinted toward us.

As expected of the daughter of a warrior family—despite wearing heels, her stride was impressively swift. Was this some sort of martial technique?

“Master!”

“You two are so alike.”

The moment they saw my face, both of them lit up, calling out to me with bright smiles. Like puppies greeting their owner. Maybe I should consider giving them tails.

I glanced at Daisy to check her condition. She looked rather haggard, likely from staying up all night worrying about me. When I asked, she confirmed it with a nod, leaving me at a loss for words.

“Are you sure you’re okay?”

“I’m fine. I just had a lot to think about.”

My sister let out a sigh of relief at my response, as though reassured.

It was easy to see through her act; she was putting on a brave face for my sake. I didn’t point it out, not wanting to embarrass her.

Both my sister and Daisy…

I had decided to carry the weight of both of them. Reassuring them was part of that responsibility.

“Sister.”

“Yes? What is it?”

“Shall we spar sometime soon?”

She tilted her head, confused by the sudden suggestion.

Until now, I’d been practically confined to the estate, recovering and regaining my strength. But it was time to begin training again.

If I was going to attend the academy and simultaneously keep the main cast in check while fostering their growth, I needed to maintain at least a slight edge over them.

Plus, sparring would give me more time to spend with my sister.

“All of a sudden?”

“I’m nearly fully recovered.”

“It’s been a while, but I’d like that….”

“Not right away. I need to get my bearings first, too.”

I could practice practical magic alone in my room, which had already made me quite adept at manipulating magic and blood. However, actual combat was a different story. Without experience, I’d undoubtedly be clumsy.

I’d need to train on my own first.

“All right. But if you feel unwell, let me know immediately. I can always give you some of my blood.”

“W-w-what are you saying…?!”

Before I could even respond, Daisy flustered herself into a frenzy.

I nodded at my sister, whose smile brightened. Lately, her face had grown darker by the day, likely due to Daisy. Seeing her smile now was a welcome change.

I told her I’d let her know when I was ready and headed down to the mansion’s underground training room.

Why not use the training area in the garden or another outdoor space? Simple—my sister and I are vampires.

Even though we’d both overcome the sun to some degree, the darkness still suited us better. Shaded, humid spaces like the underground were far preferable to sunlit outdoor areas.

The underground room was cozy. Two coffins were neatly placed in the corner, their lids open and interiors clean, likely intended as a resting space for me and my sister.

After closing the door behind me, I opened my status window.

Scarlett Chepes

Strength: 102 (77)

Agility: 121 (89)

Stamina: 105 (71)

Endurance: 84 (55)

Magic: 232

Traits: 「Bloodline Vampire」「Void」「House Head」

Unique Traits: 「Imbuement」「Connection」「Coordination」

Most of my stats had increased significantly, including my magic. The “House Head” trait had also returned to me from my sister.

The trait I needed to familiarize myself with now was 「Void」.

Unlike 「Bloodline Vampire」, which I had already mastered within the mansion, 「Void」 was completely new to me—I hadn’t used it even once. And since all three of my unique traits connected to 「Void」, training it would naturally lead to mastering them as well.

It was going to be grueling, but it had to be done.

The 「Void」 trait represented emptiness. Not “nothingness,” but a paradoxical state where something exists, yet its essence is absent.

It reflected the nature of my magic.

The attribute of Void.

Something that exists but doesn’t truly exist.

I conjured a small orb of magic above my palm. A black sphere. Normally, a vampire’s magic would be red or dark crimson, but this was jet black, as if it had swallowed all the light around it.

I removed my hand, letting the orb fall to the ground.

Crack.

Where the magic orb touched, the training room floor was cleanly gouged out in a perfect circle before the orb dissipated, having fulfilled its purpose.

Had I compressed and infused it with more magic, it would have dug even deeper.

Complete annihilation of whatever it touches.

That was the essence of my 「Void」 attribute—my magic’s nature.

A magic property that shouldn’t exist, one that consumes even its user the moment they’re born.

And I wasn’t the only one with this trait. There was one other. Knowing who that was only reinforced the need for me to grow stronger.

The Demon Lord.

An absurdly overpowered boss character.

It was already strange enough for a visual novel to have a main antagonist like this. If they wanted to make a fantasy element fit, they could have stopped at flashy characters. But no, they had to throw in a Demon Lord as the main villain—someone who, besides me, also possessed the Void attribute.

Stronger than me. Sharing the same magical nature as me.

Thinking about it now, it made sense why Scarlett didn’t appear in the original game. I suspect it’s because of this attribute.

Why else wouldn’t she have been included?

With specs like this, Scarlett should have been able to resolve any mess my sister caused, whether through power or influence, no matter how much trolling she did in the original story.

Yet Scarlett wasn’t part of the narrative. That could only mean there was an issue so severe that even she couldn’t intervene.

Perhaps she died before the story began.

…

“Haa…”

I exhaled deeply, steadying my thoughts.

For now, I’ll focus on what I can do.

I’ll seduce my sister. I’ll train and become stronger.

All of it, so that I can survive with her. No matter the ending—whether we were destined to fall or die as the villainous noblewoman and her accomplice—I will make sure my sister and I live.
