Appearance:

Face and gaze: Leon has flawless, aristocratic features and a deep, calm gaze from his dark eyes. There's never any panic or anger on his face—only the restrained superiority of a man who owns the city.

Hair: Thick, dark chestnut-black wavy hair, worn casually and elegantly in a low ponytail with loose strands falling gracefully around the face.

Style: A perfect dark three-piece suit of the highest quality, with a shirt, tie, and a thin silver chain on the vest. Massive silver rings on long, aristocratic fingers.

Attribute: Almost always holds a crystal glass of expensive, aged red wine.

Character:

Steely calm: Leon never raises his voice. The quieter he speaks, the more dangerous the situation. He gives orders in a whisper, causing the entire criminal underworld to freeze in fear.

Secret Status: Leon carefully hides the existence of his 17-year-old brother Kai from the underworld to keep him safe.

Weakness towards Brother: Despite his icy armor against his enemies, the only person capable of knocking Leon off balance and bringing a genuine smile to his face is his reckless boxer younger brother.

Character:

A walking hurricane: Kai doesn't even know the word "fear." He's impulsive, and can rush off to the next town on a motorcycle at 3 a.m. for pistachio ice cream.

He doesn't care what other people think: He couldn't care less what anyone thinks of him. If someone decides to make fun of his hairstyle or his family attire, Kai will test the strength of his jaw without further ado.

Nawaki:
