Mahākāla

This is a space-time ninjutsu that Kokorozashi awakened in his right eye after receiving the Mangekyo Sharingan. Unlike Amenoukihashi, this not allow him to send objects or other people through time. Instead, it allows him to manipulate a person's sense of time on a microscopic level through eye contact. In other words, he can take a person's sense of time and either lengthen or shorten it based on how a person's brain reacts to different changes in the world. By affecting the brain, he can also slow down and speed up a person's ability to recover, because of time being perceived differently. However, it only effects the person it was used on, as the rest of the "outside world" remains untouched.
