Jōgan

This dōjutsu was awoken by Hisaya during her teenage years. When she was attacked, her left eye was destroyed and her right eye would be the only eye with the dōjutsu now. This dōjutsu is blue in color with a darkened sclera and visible pupil.

During the first time, Hisaya did not appear to have the ability to activate it on command, instead the eye involuntarily activates when she focuses her attention on a particular person or object. As timed passed, she displayed the ability to activate it at will.

Abilities
Before seemingly gaining control of this dōjutsu, it would independently activate in the presence of dangerous/hidden targets. It can perceive the flow of chakra, enabling Hisaya to see the visible changes in one's chakra and likewise track a target through their chakra. It can clearly see the chakra pathway system and determine its most key point. It can also see through invisible barriers that connect between dimensions.

Trivia

 * This dōjutsu is officially named in Naruto Wikia as Boruto Uzumaki's Dōjutsu.
