My Assassin (Killua X Reader) [COMPLETED]

Killua cries "I do"

(Song is optional, but it conveys certain feelings for this chapter)

Y/N's P.O.V.

Today was a day before Killua's marriage. Before his whole life layed out before him, followed by closed doors and patched roads.

And I needed to meet his fiancée.

The one to open the door this time wasn't Canary, or a familiar ex-assassin. It was a girl with raven colored hair slipped back in braids, her lake blue orbs flashing. She didn't ask what I was doing, simply stepped aside for me to enter. At the far end of the hallway stood another female, but there was a difference between the two.

This one was scowling at me, her eyes narrowed to slits, they were even more venomous than Peter's when he was angry, and that made me cower in her presence. Attempting not to let my cracked mask slip, I greeted her with a cunning smile.

"I'm guessing you're my husband's little friend." She muses, stepping foward in challenge, to which I accept, copying her actions.

"And you must be his abusive betrothed. Who would expect someone with such a pretty face to have such a nasty-" my eyes dilated to an extent when she was behind me in an instant, pressing what I was guessing was an edged blade against the back of my neck.

"Celicy from house Grien. An assassin just like Killua." She pursed her lips. "You do know he's an assassin, right?"

I was frozen and unmoving, focusing on her heartbeat. It was more difficult to read other's heart rates rather than my own, but the situation required it, with me waiting for her heart to skip a beat on a moment's hesitation.

However, it never came. That's when I realized she wanted nothing more than to tear me to shreds, slit my wrists and cut my throat open, piece by piece. The way she had been taught to  deal with inconveniences.

"Now listen as closely as those deaf ears can register and thick head transfer, don't come to our wedding. Dont show your face. Because trust me, it will end in bloodshed. Assassin families from all around will be there and if you show up, they'll have a new target." Celicy's face twists into a sneer. "Not that I would mind, but knowing Killua, he'd probably try to save you, getting hurt in the process-"

I sweep my leg from under me and force her to collapse, regaining dominace with her own weapon to the middle of her brows. "You have no right to put Killua and hurt in the same sentence."

My mind moves at accelerating speed, chanting demands. Kill her, kill her, kill her, do it.

Celicy smirks up at me, fully aware that I'm incapable of doing it. Not because I'm a coward, but because I'm better than her. I don't take lives for no reason. Dropping the knife, I hoist myself up. "I won't go to your wedding in one condition," I begin, grabbing her attention because she quirks an eyebrow.

"And what would that be?"

"You don't have one at all." I watch her for a full minute, silent and contained. A perfectly still box of rippling hesitation. "This engagement wasn't your choice, was it?"

"Rain," she calls, and the girl from before makes her way next to the assassin's side in obedience. Like a dog on a leash. "Show her to the door."

I was led outside, planting my foot on the doorway, preventing the door from fully shuting,  Rain sighing. "What is it?"

"Are you a servant here?"

"Loyal to the Griens only," she answered, face falling, giving a shrug of indifference. "But every servent around here is treated the same, so yes."
