Jujutsu Kaisen: Black Flash explained

A disturbance in the fabric of space that occurs when cursed energy is harnessed within the incredible duration of 0.000001 seconds following a physical hit sits at the heart of Black Flash. Black Flash appears due to this synchronization of the metaphysical and the physical worlds. In this technique, the sorcerer's cursed energy briefly becomes dark, and the destructive capacity of the subsequent blow increases rapidly, eventually reaching a potency comparable to a conventional hit multiplied by 2.5.

But the path to releasing Black Flash is paved with obstacles and necessitates an unmatched concentration level. A prolific sorcerer, Satoru Gojo cannot summon it at his command. Any average jujutsu sorcerer can't utilize this technique. It demands tremendous talent, fighting prowess, and in-depth knowledge of the management of cursed energy.

The mysterious Mahito and Yuji Itadori, the anime's lead characters, are connected to Black Flash's potential. The sparks of black, however, welcome everyone who proves deserving, discarding preconceived assumptions of ability, so this is not a selective blessing.

Through Black Flash, Aoi Todo sharply highlights the contrast between those who have understood the essence of cursed energy and those who have not. He compares it to the abyss between heaven and earth, which is a fitting analogy given the awe it inspires.

The former record holder for the most Black Flash usage in a row, Kento Nanami, explains that after accomplishing this accomplishment, controlling cursed energy feels as natural as breathing. As a result, the user's fighting prowess is increased to 120% of their capacity, giving them an air of invincibility on the battlefield.

FAQs

Can anyone use Black Flash in Jujutsu Kaisen?

As stated above, Black Flash only occurs when cursed energy is applied within fractions of a second after a physical hit (approximately 0.000001 seconds). It demands tremendous concentration, and hence, no sorcerer, including even the genius Gojo Satoru, can use the Black Flash at will.

Why is Black Flash so strong?

Using Black Flash means being in a state of extreme concentration, similar to being in a "Zone." The resultant cursed energy flashes black and exponentially increases the hit damage to the power of 2.5.
