How to Be a Dark Hero’s Daughter

“Oh, that’s what it was.”

Ko looked at me after parting his lips.

He licked his dried lips with his tongue.

“Angel. No, sister.”

“…”

“I like you, sister.”

Ko whispered.

“Because you’re special, sister. I’ve thought many times about turning you into the same state as me. But I always failed. Even now… I can smell that man on you. A man with a non-human lineage. The disgusting smell of an animal.”

“…You mean Cedric?”

Ko chuckled.

“Yes. My instincts tell me to stay away from animal scents.”

I remembered a book I read in my past life. It mentioned vampires and werewolves being natural enemies.

Ko began to feel more and more like a stranger to me.

“Sister, when I went back to the village with Kiki, even as people were dying from the epidemic, they shunned us. They said we spread the disease.”

When the epidemic began to spread, Kiki and Ko hid in the mountains.

There, they took refuge in a small cave like a rabbit’s burrow.

Though Ko took care of Kiki with all his heart, their food was limited to fruits fallen from trees, bitter herbs, and acorns in the mountains.

It was impossible to provide proper care for Kiki there.

“I went to the village not… just to ask for medicine for Kiki. No one would give medicine to kids like us. I wasn’t expecting sympathy to that extent. Kiki just wanted to drink milk before dying.”

Ko carried Kiki all night, begging for milk.

“I was afraid Kiki would become a ghost if she died with regrets. We always wander while alive. I hoped Kiki could rest in one place after death. If she became a ghost, she’d wander again…”

However, the already dying villagers became even more distrustful.

None of them opened their doors. Some even struck Ko.

“So?”

I asked softly, heartbroken at the thought of Kiki.

“Kiki died.”

“And you were left alone, barely surviving, only to be caught by people and almost burned alive.”

“Yes. Being at the bottom didn’t bother me. But I realized that there’s even a lower point than the bottom… Here hurt.”

Ko emotionlessly pointed at his heart.

“And when I finally escaped, I started to get a fever. I thought I was going to die.”

“But you survived.”

“Yes. After being unconscious for a few days, when I woke up, I felt different.”

“…”

“I wished all those who tormented Kiki and me were dead. I dreamt of it every day. Then, I gained the power to kill anyone. That’s when he appeared.”

One day, as usual, Ko slept, drying his body in the mountains.

Suddenly, a handsome, silver-haired man appeared before him.

“He said he was conducting an experiment.”

My hands were sweaty. I nodded for him to continue.

“Sister, I knew this would happen.”

“…”

“Doctor Siebel said to me. He asked me to choose. Whether to kill or save the people of the world.”

I understood the entire situation.

‘If bitten by a vampire, one becomes a vampire.’

It’s a legend. In both my past life and this one.

But in this world, it’s slightly different.

‘Even if you drink water that’s diluted with a billionth of a vampire’s blood, humans die. But miraculously, if someone survives… they become a vampire.’

I organized my thoughts.

‘Ko drank water contaminated with vampire blood and was the only one to survive and awaken as a vampire.’

Ko was the only living vampire in this world.

“Ko, is your blood… the antidote?”

Ko nodded.

“I came to ask you, sister. If I’m a vampire, what will you give me?”

I looked straight into Ko’s eyes.
