Black Box

Black Box (絶対的不確定, Zettai-teki Fukakutei, lit. Absolute Uncertainty) is a Noble Art of Utakata Misogi.

Description
Black Box is a rare causation manipulation-type Noble Art. It allows the user to rewrite events by manipulating the outcome, as long as there is more than a zero percent chance of the outcome happening. For example, Utakata could erase Ikki's injuries with Black Box.

Weakness
Black Box can't make things happen, that have less than a zero percent chance of happening. The ability also can't create something out of nothing.
