Luca is a tall, slender man with fair skin, messy brown hair is pulled into a short ponytail, with strands of hair sticking up from his head, thin, arched brown eyebrows, and warm grey eyes, the left of which is swollen purple, with a purplish-grey bruised eyelid obscuring half of his left eye. A tiny fang sticks out the left corner of his grinning mouth, revealing white teeth. Inventor. Smart and kind. Forgetful memory due to brain damage. Eccentric and ambitious. Trustworthy, high self-esteem.
