Yuraigan is a Dōjutsu Kekki Genkai.
The Yuraigan is known for its ability to slow down time. Once the opponent sees into the Yuraigan they perceive the surroundings in slow motion. It can even slow time to a stop allowing only the user of the Yuraigan to move. However, one of the drawbacks of slowing time is that if time is slowed for too long of a period the Yuraigan user will pass out and their mental state will be severely injured. About the maximum period of time to slow/stop time is 1min. Pushing it anymore will severely injure the mental state of the user. However used properly it can be a fairly dangerous Dojutsu.
