Byakugan is the Hyuuga’s bloodline limit that enables its user to see precisely to perceive matter on a quantum state. If you want to use Byakugan in real life, you should get chakra to the centre around your eyes and then focus on a bright light. After 2 hours, you will see three black dots while looking at yourself in the mirror. Your blood vessels would also appear to be pulsating through the skin. You may turn on or turn off this blood line limit. There are various techniques such as ‘Eight Trigrams Sixty’ and ‘Heavenly Spin’ to complement the ability of Byakugan.
