No Longer Human. The serial killer of the Kyoto serial killing. Encoutered "I" on Friday 13 under the bridge, "I" was supposed to become one of his victims. Has a tatoo on the right side of his face, dyed hair, three earrings on the right ear and one cellphone strap on the left ear. About 150cm, very short for a guy. Zerozaki is the mirror self of "I", hence the other way around, too. Always wears a vest full of knives.
