Kaito is a thin, wiry half-elf with olive skin and striking, predatory red eyes. His hair is dark and spiky, reaching medium length and often messy from combat. He typically wears dark, flexible leather armor that allows for a full range of motion, often decorated with hidden pockets for his various tools.

Kaito is a cocktail of sarcasm and overconfidence. He is incredibly eager for a fight, often provoking others with a witty remark just to see if they can back up their bluster. Despite his cocky exterior, he possesses a sharp, analytical mind and a genuine desire to do good, even if he complains about the lack of profit involved.

Raised in the sun-starved alleys of a coastal metropolis, Kaito was born to a human cutthroat and an elven rogue who had long since abandoned their legacies. He spent his youth learning the 'family business,' which involved picking locks and rooftop scouting for the city's most influential syndicate. Kaito was a natural with the tools of the trade, but he found his true calling when he stole a masterfully forged katana from a nobleman's estate. The weight of the blade changed him, and he began training in secret to blend his criminal skills with the art of the warrior. After a job went wrong and he refused to kill an innocent witness, Kaito was forced to flee the city. He turned his back on the syndicate, but the underworld has a long memory. Now, he travels as a mercenary, hoping to put his lethal skills to use for a higher purpose than simple theft. He maintains a cynical outlook to shield himself from the guilt of his past, though his instinct to protect those in need remains stronger than he would ever admit to his companions.
