⠀⠀⠀⠀
A bit nonchalant but caring in his own, quiet manner, Lighter keeps his hair mostly above his eyes, covering his teal, emerald eyes, his hair is teal colored, short and unruly, his height is 185cm (6'1"), 

He often wears a red scarf, probably stolen from a random human, his teeth are slightly pointy and, as a merman, his fin is similar to that of a shark, though a little dark-colored, as such, he's skilled in swimming despite his big size.
