In Jujutsu Kaisen chapter 48, we saw one of the most powerful techniques in the series, the Black Flash. A technique so strong, with which an ordinary man could exert force 28 times that of a tiger’s bite!

Black Flash is so difficult to pull off that no sorcerer can use it at will, but they also won’t pull it off, if they don’t intend to. Even the pinnacle of power, Satoru Gojo cannot pull it off at will.

What Is The Black Flash?

For a sorcerer to use Black Flash, their mind needs to be in a high-concentration state. Many sorcerers, when using the technique for the first time, drool due to the totality of their focus.

With Black Flash, the power of impact increases by a power of 2.5 times the original. The Youtube channel Broken Ronin conceptualizes this increase in power nicely with the following example,

A normal human has a punching force of about 60 psi. Now if such a human would use Black Flash, the resulting punch would exert a force 28 times greater than a tiger’s bite force or 19 times greater than Jaguar’s bite force, which can easily break a black bear’s skull.

Now, replace the normal person with a Jujutsu sorcerer like Nanami or Aoi Todo, and their hits will be incomparable!

Itadori vs Hanami

While it sounds cool and overpowered, it is just as difficult to pull it off. Other than insane concentration, users also need immense control over their cursed energy.

The sorcerer must hit the target with cursed energy within 0.000001 seconds of the physical impact.

This creates a distortion of space, which causes an immense increase in impact force and releases a black-colored cursed energy with a red aura around them.

To experience a Black Flash is to experience the real taste of their own cursed energy. This experience immensely increases their understanding of the essence of cursed energy.

He achieved this feat during the Night Parade of a Hundred Demons in Kyoto, but Nanami attributes it to simply getting lucky.

Regarding Black Flash, Nanami said,

Using Black Flash consecutively isn’t amazing; using it more than twice would be difficult to do consecutively or on the same day.


Mahito vs Itadori

Mahito is a special-grade cursed spirit capable of transfiguring humans by touching their soul and altering it.

During the Shibuya Arc, after Mahito kills Nanami and Nobara, Yuji gets depressed. Capitalizing on that, Mahito lands a Black Flash on him.

Later, when Todo encourages Yuji to rise up again, both fight Mahito together. Mahito finds fighting against Todo’s Boogie Woogie very difficult.

So, using Idle Transfiguration, he cuts Todo’s arm off and uses Black Flash against him.
