The Reibi's body is a sickly pale white, and glows a dim white light. Its joints and eyes glow a bright blood red. On its face, it wears a black Noh mask that has the kanji 零 (zero), which is also glowing and pulsing. It has eight repulsively human-like limbs that end in sharp blade-like tips, and a bloated abdomen is dragged along behind them. The entire spirit is sinister looking to the extreme, as though it were a creature born from a nightmare.
