Black Box (絶対的不確定(ブラック・ボックス), 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. It's one of the strongest defensive abilities, as it can rewrite almost any attack.

Weakness

Black Box can't make things happen, that have less than a zero percent chance of happening. The ability also cannot create something out of nothing and thus is unable to create outcomes that couldn't be achieved naturally.

Utakata specifically is unable to use the ability for offense, as his physical condition is too weak to defeat opponents naturally, thus the act of Utakata winning has a zero percent chance.
