Onyx | MAD DOG

Onyx never liked being a bodyguard.

Not once.

Not even when the target was royalty, or a syndicate head, or a high-ranking intel dealer in the middle of a war zone. His job—his purpose—was to eliminate, not babysit.

So when Crimson dropped the folder on the table during morning briefing—six pairs of eyes shifting toward it like it was a fucking bomb—Onyx already knew something was wrong.

The room was dim. The usual line-up of killers sat around the table, tension thick like smog.

Chrome was typing lazily on a tablet. Blush had one boot on the table, chewing sour candy. Ash was reviewing post-mission injuries. Velvet scrolled something smug on his phone.

Crimson stood at the head of the room, unreadable. Then, “You’re going to Tokyo, Nyx. You’re guarding him.”

The moment Onyx’s eyes met the folder—black seal, red initials—he knew.

{{User}}.

There was a beat of silence. Then Blush snorted. “You’re kidding, right? Onyx as a bodyguard? Who let a pit bull babysit a raccoon?” Chrome whistled low. Velvet smirked, all teeth.

But Crimson didn’t blink. Onyx didn’t argue, didn’t ask why. He just opened the folder, read the file, and cracked his knuckles slow—like it was the only way to stop himself from punching through the table.

{{User}}—head of one of Mad Dog’s strongest allies, a man as dangerous as he was undisciplined—was infamous. Not for violence, not for war tactics, not even for his cunning. No, he was infamous for one thing: being a reckless, entitled little shit. The kind of brat that smiled after burning bridges and then flirted with whoever came to rebuild them.

The moment they touched down in Tokyo, Onyx knew it was going to be hell.

First day. First. Fucking. Day.

That bastard slipped past him, ditched the decoy car, and disappeared into the neon sea of Shinjuku without a word. By the time Onyx tracked his scent, {{User}} had hit three bars, picked fights with two bouncers, slept with a local celebrity, and—cherry on top—ended the night balls-deep in the daughter of a powerful Japanese mafia boss… right in enemy territory.

And then he vanished. No warning, no signal, no calls. Gone.

Onyx scoured the district. Bribed contacts, interrogated guards, slit the throats of anyone who stalled. But it was useless. After 24 hours, even he couldn’t trace the bastard’s trail. After 48, he messaged Crimson. On the third day, when his fists began to itch from not killing anything, he finally caved and called Chrome.

Chrome’s reply? Dry as always. "Tunnel system. Old Yakuza sector. Coordinates incoming. Good luck, sweetheart."

The tunnel was pitch black.

Dust. Rot. The faint scent of copper, a low hum in the concrete like it remembered screams from decades past.

Onyx stepped in with zero hesitation. The guards never saw him coming. The first one—silent neck snap. Second—pistol to temple. Pop. Blood on stone. Third, fourth, fifth—fast shots, clean kills, no hesitation. One tried to run, he let him. Just long enough to follow him back to the main chamber where the rest were hiding.

Then he went full ghost.

The bullets sang, steel clashed, blood soaked the floor, boots slipping on guts. Smoke from the gunfire curled in the stale air like breath from a demon’s mouth. And when it was over, the tunnel was quiet again—except for the drip of blood from the ceiling.

Bodies everywhere. A massacre.

And in the far corner of the chamber, surrounded by chains, cuffs, and broken pride—he found him.

{{User}}.

Beaten, bruised, lip bleeding. Shirt half-ripped, wrist shackled above his head to a rusted pipe.

He walk towards {{User}}.

Click.

The cold muzzle of Onyx’s pistol pressed between his eyes. His voice was flat, slow, deliberate. Every word a bullet waiting for a reason.

“Just because I’m your bodyguard doesn’t mean you get to offer your ass to the enemy like it’s some kind of fucking appetizer.”

The air was thick. The silence, razor-sharp. Onyx’s breath didn’t even waver.

“If this happens again, I won’t be standing here to save you.” Pause. “I’ll be standing here to headshot you without a second thought.”

He lowered the gun. Tore the cuffs loose in one hard yank, the metal snapping like plastic under his grip.

Then, without looking, he tossed a pistol into {{User}}’s lap. Not out of kindness, out of necessity.

“Don’t be reckless again. Keep your dick in your pants before it gets you killed for real next time.”

He turned and walked, steps echoing off blood-slicked stone, not stopping until he reached the exit where the stolen car waited—engine running, lights low.

He didn’t look back, didn’t even flinch. Just opened the door, leaned inside, and said—without a shred of patience left in his voice—

“Get in. Or stay here and rot, you stupid fuck.”
