Mercy.

A/N: Just a short, random drabble for my favorite hitman's birthday :-) Raw and unbeta-ed because I was suppose to be in a hiatus right now from fanfiction. But I just can't help but make a drabble for Reborn. Happy birthday, Reborn, and I love you so much.

Mercy.

That was one of the words that the infamous hitman wasn't associated with. Sure, he has the laws backed up but in the end, an assassination is an assassination and he'd be damned if he doesn't finish his missions. There was a lot of pride and name on the line, too much on the stake.

Walking with slightly shifting steps in a monotonous pace, he looked at the hooded teen who had just appeared and stopped in front of him while he was still on the hunt for his new target.

He raised an eyebrow as he silently whipped his gun in the teen's direction.

"Ahh," the teen simply shook his head as he took off the hood and let his amber eyes meet with Reborn's black ones. A smile on his face, he said, "Enough of this, Reborn."

Reborn, for his part, twitched, and he coldly asked, "Who are you?"

The teen laughed for a good few seconds before he said, "How you can forget me and everyone else, I have no idea why."

He paused and shook his head as he continued, "Perhaps this was a side effect of breaking the Arcobaleno curse?"

"I have no time for your cryptic messages," Reborn drew the gun at his head and clicked on it, "Answer my question."

"Oh, hahaha, I'm your no-good student, Sawada Tsunayoshi," The brunet smiled as he said that, a nostalgic smile. He crinkled his eyes as he added, "And today, on your birthday, I'm here to teach you about mercy."
