It was said on that web page that the Tenseigan is some kind of an evolution of the Byakugan eye technique that the Hyuuga clan members have been using throughout the years. It was still uncertain if this is really an “evolution” or like a dormant power.hat’s absurd! We’ve all seen the power of the Rinnegan and it is THE MOST powerful Dojutsu among the Three Great Dojutsu. As for the claim that Tenseigan is on par with Rinnegan, I won’t believe it until I’ve seen it in action.
