A/N: I own nothing! All names are fictional! I had this idea of what Killua's first kill would have been like. This didn't turn out as detailed as I wanted it but I didn't want to make it M rated.

"Remember Kil," Illumi instructed a five year old boy with spiky white hair and sharp blue eyes. "Do not make yourself known until it is too late." With that, the tall, dark haired teen disappeared into the shadows.

Killua sighed in annoyance. "He acts like I'm going to screw up my first kill," the boy thought as he watched all the civilians walk pass him by in the plaza of a small city. "I've been training for this since before I could use the potty."

He kept his eyes focused on the bank across from him where his target would soon depart. "Maki Kenshin, 45 years old," Silva's voice echoed in Killua's head. "Your employer wants him killed discreetly with absolutely no witnesses."

"Who is the employer?" Killua asked. He maintained a blank expression throughout the briefing.

"His wife, Naoko. The man is known in the underworld for trafficking children." Before Killua could speak, "I don't doubt your training with Illumi has made you more than capable to handle a pervert. Just keep it as quiet as you can."

So Killua and Illumi devised a plan for how the boy would handle his first assignment. As a middle-aged man with gelled black hair exited the bank, Killua moved. Adopting a wide-eyed gaze and putting his tiny fist next to his face, his other hand tugging on the hem of his jacket, he looked like a lost child. He walked towards the bank, turning his head from side to side like he was looking for someone.

"Excuse me, mister," his voice trembled as he caught the attention of his target. "I'm trying to find my older brother. We were supposed to pick up some milk for my mommy but we got separated."

Maki smiled, a glint of interest in his eyes. "Don't worry, kid. I'll help you look for your brother." The man offered his hand. Killua's hand was small and vulnerable in his grip. They began walking down the street. "What's your name?"

"Kioshi," Killua lied. Illumi decided this would be Killua's alias should he need it. "Where are we going?"

"To the police station. They can find your brother there. Hey," he acted like an idea had struck him. "How about we take this shortcut?" He pointed down an alleyway that clearly led to a dead end. Killua did not question it, he knew what the man probably wanted to do. Men like Maki would sometimes "sample" their products. Killua let the man lead him down the alley.

"Has anyone ever told you how adorable you are, Kioshi?"

"Hmmm," Killua put his index finger to his chin. "A few people, mostly my mommy."

"And so well behaved. You must be very quiet."

"Mommy tells me to keep it down. Especially around adults."

"She sounds like a good woman." They stopped behind a dumpster. "Kioshi, do you wanna play a game?"

Killua pretended to look interested. The bulge in Maki's pants was far from subtle.

"I have some candy in my pockets that I want you to have. But you have to fish it out. I'm warning you, my pockets are pretty deep."

"Okay," Killua thought. "This has gone on long enough." His nails sharpened to points.

"So do you wanna pl-?" Maki choked on his final words as his throat was slashed, blood gushing down his shirt. He went to his knees and was eye-level with Killua before he collapsed. Killua's eyes were cold.

"Disgusting," Killua spat.

"A little sloppy, Kil," a voice next to him remarked. Illumi seemed to have materialized. "But no witnesses, so a job well done."

"You could have taken him out before he said all those things," Killua turned his glare to his older brother.

"This was your job, remember? Besides, you kept up a nice performance. Mother and father will be proud." He placed his hands on Killua's shoulders. Killua fought the impulse to shudder. "Well, we should return now."

The two brothers walked away, leaving the body to rot in the trash.
