Till Death Bonds Our Hearts (Killua x Reader)

Prologue

- - K I L L U A - -

My name's Killua.

I'm the heir of the Zoldycks. From the start, I know that I am going to become one great assassin and continue the family business.

Being a family heir seems like everyone's dream come true. But for me, apparently, it is not. I often get electrocuted, tortured, and those methods are considered as forms of "training" for me. At a young age, I had mastered the art of assassination, and I continued training up until I grew up to the person I am now.

I'm tired of living by the assassin's way of life. I wish that I can venture out in the world, and have exciting and thrilling moments to treasure until the day I breathe my last.

I wish that I can stop killing people. I mean, it's boring. I'm tired of seeing cadavers strewn out in front of my very eyes. I'm tired of hearing people's desperate pleas for their precious lives.

I want to be a new person. Seriously speaking, though. I hate the life I'm currently living in. It really sucks. There's nothing much to do.

My life revolves around waking up, training, killing, then sleeping. Typical, constant routine of mine. Today, I was assigned by my older brother, Illumi, to kill (y/n) (l/n),  the daughter of one of the most influential members of the mafia. I heaved a sigh, and I could only hope for at least a challenge or two. Killing people is fairly easy for me, heck, I can do it with my own eyes closed.

Not that I'm bragging about it though. Assassination is the family trade. That's what makes our name stand out. We are a family of ruthless killers. We're infamous murderers. We're feared.

Honestly, I don't really want to be feared. I want a normal life, like the other kids of my age.

That's what I thought when I was casually walking towards the destination of my target. She lives in this house in the mountains, and she lives alone, according to the information given by my older brother, Illumi. It seems so saddening. She's isolated from the outside world, and she too, can't get a glimpse of the world beyond her borders. Pretty much like me.

Right now, second thoughts were crashing inside my stupid mind. I'm torn between sparing her life or putting that life of hers to an end.

I mentally slapped myself. An assassin never pities anyone, no matter how miserable they are.

Why am I sympathizing with someone I never know?

Sympathy? That little word seems non-existent in our vocabulary. I was trained to show no remorse as an assassin. I mean, all I have to do is rip people's hearts off and leave them lifeless, or torture them to get them to answer important questions. To me, it's easy. Like what I said earlier, I can kill with my eyes closed. Killing never posed a challenge to me.

Even so, it doesn't mean that I enjoy killing.

Anyway, I found myself stopping abruptly as (h/c) locks entered my field of vision. I saw a faint figure of a girl running towards my direction.

That girl is sickeningly familiar.

Wait a second...

I recalled the image Illumi showed me before I left for this mission. She's my target.

Instantly, I sharpened my claws, and chased after her silently. I climbed up trees so as to get a bird's eye view of my target. However, I think she must have noticed me, because, she hastened her pace.

Tsk. She's fast, but I know I'm faster. She doesn't know me at all, it's kind of hilarious.

I saw her panting, catching her breath with her back turned against me. She has been delivered into my grasp. Alright. I went for the kill.

I put my hand through her back. A second later, I held her heart in my hand, and she fell to the ground, devoid of any life in her body.

Surely, she's really dead now. I knelt down, and closed her eyes. I got up, and began walking back home. Then, I saw someone, and she looked like my target.

She had the same (h/l) (h/c) hair, from what I can see from behind. Her back was turned against me like before, and she wasn't wearing her (f/c) colored shirt and (s/f/c) short and shoes. Instead, she was wearing a white dress that danced gloriously with the gentle morning breeze.

I approached her, then I said her name. "(Y/n)?"

She turned towards me, and I caught a glimpse of her face which held sadness.

"Why'd you kill me?", she sobbed.

"Ha?! You're alive?!", I asked, shocked. She's not supposed to reply, she's dead, and she's just a mere illusion!

"Of course not, you killed me..."

Damn. The cat got my tongue. Even if I opened my mouth to speak, the words in my mind cannot be read by my vocal chords, so I'm speechless.
