Black Flash

is a phenomenon in jujutsu that greatly amplifies the user's physical strike when cursed energy is applied to it within one-millionth of a second.
== Description ==
Black Flash is a distortion in space that occurs when cursed energy is applied within 0.000001 seconds of a physical hit. When a sorcerer is able to achieve this, their cursed energy flashes black, and the destructive power of their strike is equal to a normal hit to the power of 2.5.
 
Unleashing Black Flash requires incredible concentration and no jujutsu sorcerer is capable of using it at will, not even Satoru Gojo. It does not occur randomly and requires immense skill and combat potential to pull off. While Yuji is thought to be blessed by the sparks of black due to his potential, the same goes for Mahito because the sparks do not choose who to bless.
According to Aoi Todo, the difference of the ability to understand the essence of cursed energy among those who have used and those who have never used the Black Flash, is the difference between heaven and earth. Kento Nanami, the former record holder for most consecutive uses of Black Flash, explains that using it consecutively is nothing impressive. Regardless of how the user achieved it the first time, whether through skill or simple luck, they enter a state where manipulating their cursed energy becomes something as simple and natural as breathing. It can result in a feeling of omnipotence, as if everything revolves around them. This leads to a greatly increased performance in combat, allowing the user to operate at 120% of their maximum potential.
==Usage== 
===Yuta Okkotsu===
In the anime, when Yuta Okkotsu landed a hard punch on Suguru Geto after breaking his sword by imbuing it with too much cursed energy, he hit him with Black Flash.

=== Kento Nanami ===
Kento Nanami believes that using Black Flash consecutive times isn't anything to celebrate. After unleashing Black Flash more than once, doing so repeatedly becomes a much easier task. Nanami compares using Black Flash to being "in the zone", the state of elite focus and feeling of being at the center of everything that professional athletes experience while in a game. 
Nanami's record four consecutive Black Flashes were against cursed spirits during the Night Parade of a Hundred Demons in Kyoto. Despite holding this record for over a year Nanami accredits it to getting lucky.

===Yuji Itadori===
During the Goodwill Event, Aoi Todo was able to teach Yuji Itadori how to harness his cursed energy by properly timing it with his superhuman speed and strength. By explaining how to make his cursed energy flow properly and pitting Yuji against Hanami, Todo was able to help Yuji unleash Black Flash against the special grade curse. 
Yuji's first Black Flash dealt a great deal of damage to Hanami. While "in the zone" Yuji was able to land a rush of four Black Flashes that completely overpowered the special grade curse. This rush tied Kento Nanami's record of four consecutive Black Flash strikes. 
While fighting two-on-two against Eso & Kechizu, Yuji and Nobara both used Black Flash together to defeat the Death Paintings. Yuji's punch destroyed Eso's arm entirely, and so quickly that the incarnated special grade cursed object couldn't even react. It was here where Yuji proved to be the man chosen by the sparks of black. 
Yuji was able to utilize Black Flash multiple times in his final battle against Mahito. Once again fighting alongside Todo, Yuji capitalized on multiple switching opportunities presented by Boogie Woogie to land direct hits on Mahito's soul using Black Flash. He was able to defeat Mahito's final form by hitting him with a Black Flash imbued with maximum cursed energy.
During the final battle against Sukuna, with the help of Larue's distraction, Yuji was able to land a powerful Black Flash against the King of Curses. He went on to unleash a rush of six consecutive Black Flashes against Sukuna afterwards, surpassing the record by almost twice the amount.

===Nobara Kugisaki===
During Nobara Kugisaki and Yuji's battle against Eso and Kechizu, both sorcerers managed to land a dual blow of Black Flashes to the curse-human hybrids.

===Mahito===
After emotionally breaking Yuji by fatally injuring Nobara, Mahito landed a Black Flash strike on an unprepared Yuji, launching the sorcerer across Shibuya Station and overwhelming him with numerous attacks. He used it once again during his battle against Aoi Todo after weakening him with Idle Transfiguration.

===Aoi Todo===
During the fight Yuji and Aoi had against Mahito in Shibuya, Aoi Todo managed to perform a Black Flash by kicking Mahito, not wanting to be left behind his "brother's" growth. However, this was unable to do any lasting damage to the cursed spirit, due to his soul being unaffected by the attack.

===Satoru Gojo===
Satoru Gojo had managed to perform Black Flash for the first time sometime before the 2018 Kyoto Goodwill Event. Despite his overwhelming power and proficiency with cursed energy manipulation, even he is unable to use the ability at will.
He managed to use Black Flash against Sukuna during their battle in Shinjuku, dealing a devastating strike when the King of Curses least expected it. He went to on use Black Flash three more times against Mahoraga and Agito, shikigami summoned by Sukuna using the Ten Shadows Technique.

===Sukuna===
During his clash against Maki Zenin, Sukuna unleashed Black Flash against the girl physically gifted by Heavenly Restriction. Landing a Black Flash-enhanced strike on Maki, the punch launched her through a highway's railing. Later on, Sukuna unleashed a second Black Flash on Larue, crushing the sorcerer against a wall and causing the latter to spit out blood. He went on to land his third Black Flash against Maki, which increased his output for Dismantle, and his fourth one against Choso, who used blood to reduce its damage. He later hit Yuji with a fifth Black Flash during their duel.
