Zero

Zero has apricot skin, long, black hair that is usually tied into a samurai-like ponytail and brown eyes. He wears a black one-sleeved bathrobe/kimono-like outfit with gold trim, black hakama pants, and brown geta-like sandals with black straps. He also ties his hair using a yellow hairband. Zero is a NULL who served in the Cromag War as an ally to New Mecca alongside another NULL, Fifteen. He was selected as a child to be a member of the Gamma NULL category, the most dangerous type of soldier produced by the program, because of his aggression and mental problems. As part of the program, he was administered the experimental drug Chronos, which gave him incredible precognitive abilities allowing him to predict entire combat scenarios before they even happen, predict the correct answers out of an interrogation, and rewind time upon death After the war, Zero began working as a killer for an unknown employer that is implied to be the government. Due to his use of Chronos (and a near-fatal head injury during the war), Zero soon lost his memory of much of his early life. However, he retained his abilities from the NULL program and continued to use them during his time as an assassin. He’s quiet, barely speaks and doesn’t like to sharing about his life.
