The Beast Within (Shinkai/Kaishin)

Play with me

Shinichi started to feel anxious as closer the deadline came. Was he today's prey? Was he today's hunter? KID was going to determine his fate in a few minutes.
He probably figured him already out, Shinichi mused internally. His disguise was perfect and still... he couldn't shake off the feeling of being watched, cold eyes drilling into his flesh, piercing heart and soul, eager to extinguish his last bit of sanity.
Agasa-hakase was safe, Haibara was safe, Ran was safe. That had been Shinichi's mantra the entire time. KID was targetting him, not them. His family was completely safe.
Shinichi let out a breath of exhaustion and closed his eyes for a moment to try and calm his heartbeat ringing within his ears. God, he was nervous.
The last countdown. Nakamori-keibu stared at his watch as if it had personally offended him and nobody said a tone. Shinichi didn't care for today's target. It was only show to hide the real purpose of this heist... right?
Sapphire eyes tarned by brown contacts flashed back and forth over the crowd of Task Force members, trying to pick out any individual which might be KID in disguise.

Silence.

Shinichi feared that the man next to him could hear his deafening heartbeat. Tensed muscles began to cramp as nothing happened. Where the heck was KID? He was never unpunctual.
Then suddenly, an explosion. Another one. Three. The building began to shake and Nakamori-keibu was the first one back to his senses.
"Again?!" Shinichi hissed and made his way out of the building as fast as possible, avoiding to get waltzed over by the chaotic Task Force. Was KID really doing the same thing twice? Bomb up a building to kill him?!

No.

This was different.

Shinichi paused in his steps, deductions catching up with him. KID hadn't shown himself yet nor did he try luring him to some place he couldn't escape fast enough without hurting himself in the process. This time, it wasn't his death.
His eyes lasted upon the door to the exit, unsure wether to trust his selfpreservation sense or his instincts. Shinichi settled for the latter and turned on his heel around, slowly marching back into the main hall which was, by now, completely void.
Today's prize was gone from its place, the empty spot was the first thing which caught Shinichi's eye. Flickering lights above him was the second one and the detective almost laughed out as he remembered this clichéd scene out of a horror movie he had once watched.
"KID," he stated, calm, quiet, maybe a little demanding. A figure loosed itself from the shadows and Shinichi's heart nearly stopped, wow, he hadn't awaited KID to face him this easy.

Shinichi stuffed his hands casually into his pockets to appear calm and carefree as ever.
"Now that you scared the unwanted audience away... I assume you want to talk, KID?" he offered and was surprised KID hadn't made any of his flashy greetings towards his old rival. Instead, he smiled back... cold and calculating.
"I didn't doubt your conclusion would force you back into my near," the magician finally said in disturbing glee, followed by a small pause. The building had calmed down by now from the explosions and Shinichi had trust into the thief that it wasn't meant to collapse onto him this time.

Slowly, KID inched closer, every step calculated and carefully thought through; Shinichi allowed it. It wasn't until both were face to face that Shinichi tried to swallow down that nervous lump blocking his throat and had to resist the urge of backing away.
"Why aren't you running?" KID proceeded to ask, feet moving him around Shinichi and behind him. The boy didn't dare to turn around and instead contered as collected as possible.
"Because you won't kill me."
"How can you be so sure?"
"You would have done it long ago the same night I had been shot after your first try failed."
KID chuckled and Shinichi didn't know wether it was actual amusement KID felt. The boy closed his eyes and took a deep breath through his nose.
"Did you think about my offer?"
"...I did."
KID proceeded to wrap his arms from behind around his stiff Meitantei and rested his chin on his shoulder, indigo eyes glaring mischievously at him. Shinichi was almost sure KID could hear his panicking heart right now.
"I need to kill you, Meitantei... I want to kill you. This is my deepest wish. And still..." he purred in a low voice, "...you are fascinating me. I don't understand why. I want to kill you but instead I favor to play with you... make you cry, bleed... I want to cause you pain... I want to take your body piece by piece apart..."

Shinichi had broken into a cold sweat by now and was trembling in KID's painfully gentle arms, barely able to stand over his panic and not make a run for it.
"Let me help you, KID. I want to return your memories to you."
"You would live together with your murderer..."
"A-and?!" Shinichi spat, whirling around to grip the surprised KID's shoulders. Damn, his voice was cracking.
"I-I want to help you, KID. I want you to become the person you have been before."
"I wouldn't be able to control myself in your near." KID's tongue laved at his bottom lip to moisten it, lips curling up into a devilish smirk directed at his detective. Shinichi exhaled shakily and closed his eyes for a second to get rid of this horrifying image.
"Y-you were fine after hurting me the last times. Do so. Hurt me as much as you want, whenever you want. If this satisfies you... I'll pay the price to return you to yourself."
A weak smile tugged at Shinichi's lips once he reopened his eyes and saw the baffled look of his thief which turned smug in barely a second, reminding him of a satisfied cat.
"If you are able to bear it... I'll accept~ But that means, you are mine. And I will not hold back even when I keep you alive."

Shinichi never thought he would willingly invite Kaitou KID into his house... especially with the given circumstances. But they made a deal and backing out was impossible, even if Shinichi would have wanted it.
As soon as the door closed, Shinichi found himself pressed against the wall and hissed while the metal blade of a knife cut into his neck. KID was close, too close, placing light cuts all over his throat, pupils dilating at the blood flowing out in a steady stream and suddenly he latched onto his neck, sucking and devouring the blood.

Shinichi grimaced and let out a breathy gasp, eyes squeezing shut to concentrate and remain calm. He had sold his body to KID. He had to endure it.
"Pay attention..." he whispered into the top hat, trembling arms wrapping around his tormentor, "I am still low on blood after the gunshot..."
KID let out a small purr and began to lick on the cuts instead to get them nice and clean again.
"Don't worry... I'm only playing~"

Right.
KID was only playing.
