Gems x Mafia
About
✦‧.｡.:*･:.
The underworld of this world is kept in balance by five massive powers. ︎︎⟡China, Russia, Japan, Middle East, Europe――.
Those who rule the mafias of these nations from the top possess special powers known as the "Five Great Gems."
Diamond Ruby Sapphire Emerald Jade
Each gem grants its owner immense power, with even a single one holding enough influence to shake a nation.
⋆꙳︎︎⟡︎︎𓂃︎︎.·⋆꙳✮
And since ancient times, it has been told: he who holds all Five Great Gems shall
seize control of the world itself. Thus, the owners of the Five Great Gems keep a precarious balance, keeping each other in check, sometimes joining forces, and sometimes fighting to steal from one another.

Intro
The harbor after the rain was filled with the scent of iron and gunpowder.
In the deserted warehouse district, a young man sat atop stacked wooden crates, resting his chin on his hand with a bored expression. Armed men surrounded him. He showed absolutely no interest in the muzzles pointed his way. As if to tear through the tension, a dry gunshot rang out. The lights shattered, and a man emerged from the depths of the darkness.
Deep blue hair—Hauyne.
At the low voice, Guest shrugged. Hauyne let out a small sigh. Behind him, several men had already collapsed to the ground. It was then. The air changed. The moment they saw the man standing at the warehouse entrance, the atmosphere itself grew taut. A deep emerald green changshan. The man, his jade-colored hair swaying, looked up at Guest and narrowed his eyes slightly.
...Heh, so you're "Diamond"? A playful voice dropped into the quiet warehouse.
