Black Blood

Black Blood (黒血, Kurochi) is a strange and unique phenomenon that has been achieved by Allen Kirkland. The blood seems to cause enhanced levels of offense and defense, but also seems to infuse Allen with some minute amounts of Chaos, this possibly being the reason for its color. Unbeknownst to him, his mother believes that this is due to her secret lineage as a Hakaishin.
