In the Jujutsu Kaisen universe, Black Flash was once considered unreliable, but Chapter #256 changed that, making it a powerful ability. Ryomen Sukuna surprised everyone by using two consecutive Black Flash strikes. This enhancement multiplies the power of a strike by 2.5 times. While powerful, Black Flash is difficult to activate and often occurs when a sorcerer is at their limit. In Chapter #255, Black Flash helped Satoru Gojo regain his Reverse Cursed Technique. This revelation shocked fans and added a new dimension to Black Flash, showing its potential for recovery. As the story progresses, it is clear that Black Flash will play a significant role in determining the fate of the world, especially in the battle between Sukuna and Yuji. Jujutsu Kaisen fans can delve into this heightened version of Black Flash in the manga and anime series.
