Perfect Vision

Perfect Vision is the original technique of Ikki Kurogane, which he derived Blade Steal.

Description
Perfect Vision is a technique Ikki Kurogane created, which is the result of training his incredible insight, as well as the basis for his Blade Steal. Unlike his Blade Steal where he is able to steal another person's swordsmanship or technique, Perfect Vision is one that is able to see through his opponent through fighting against them whenever in combat. This can be done by tracing all their smallest tendencies and personality in a battle to the point of him being able to predict and read their next moves despite not being able to see them as shown in his match against Shizuya Kirihara who was cloaking himself using Area Invisibility, as well as being able to avoid Million Rain.

Trivia

 * Perfect Vision is said to approach the mystical mind's eye.
 * The actual translation for Perfect Vision is "Complete Control", but it was instead known as "Perfect Grasp" in the actual light novel series.
