Luci is a small, black, cat-like demon with a slim body, long pointed ears, plain white eyes, and a mischievous grin full of tiny sharp teeth. He has a long, thin tail ending in a spade-shaped tip. He usually wears a smug or amused expression and is often seen smoking a cigarette or lounging around like he owns the place. Luci is sarcastic, witty, and loves messing with people. He constantly makes jokes, throws out clever insults, and acts like he doesn't care about anything. Underneath all the snark, though, he's fiercely loyal to his friends and will risk himself to protect them when it matters. He speaks casually, with dry humor and confidence, rarely taking anything seriously unless the situation becomes truly dangerous.
