Jujutsu Kaisen: Sukuna’s Fugue – Did Akutami Reuse a Power from ‘No.9’?

Jujutsu Kaisen: Sukuna's Fugue - Did Akutami Reuse a Power from 'No.9'?

Alongside Kenjaku, Sukuna is the big baddie in Jujutsu Kaisen. That is a fact that everyone who is following the series knows. Sukuna is a cursed spirit and is said to be the King of Curses, which speaks enough about his powers and abilities. His ■ has, despite not appearing often, become a notorious technique, and it is often talked about, but what if it is only a copy? Akutami’s one-shot titled “No.9”, which came out before Jujutsu Kaisen (prequel included), contains something similar. In this article, we will address the theory that Akutami copied himself when he taught this technique.

  • Article Breakdown:
  • Sukuna’s ■ is a special technique whose name Sukuna keeps hidden, but it allows him to use flames to defeat Jogo in Shibuya. It has been dubbed the “Black Box,” and its effects still have to be explained.
  • Akutami’s earlier one-shot, “No.9”, has a similar technique, which allowed one of the characters to summon various weapons from a storage-type move, i.e., to use attacks he could naturally not use.
  • Sukuna’s ■ is activated by the command “Open” (Fuuga in Japanese), while the technique in “No.9” was called “Fugue,” so a theory proposing that Akutami copied himself in Jujutsu Kaisen has been proposed.

The theory states that Sukuna’s ■ is basically identical to “Fugue” technique

During the Shibuya Incident, when Sukuna faced off with Jogo, at one point, he used the ■ technique, dubbed the “Black Box,” to conjure flames and use Flame Arrow to defeat and kill Jogo. Everyone was surprised, as Sukuna was not a fire user, but it seemed that the ■ allowed him to use these flames. But how?

Well, from what we could gather – and we still have very little data to work with – Sukuna’s ■ is seemingly related to his Innate Technique, or is his Innate Technique, and it allows Sukuna to either story various techniques to reuse them, or to mimic them. Sadly, we don’t know anything officially at this time, but we assume that the series is going to reveal more about ■.

But, while we’re waiting for an official explanation, we’ve stumbled upon an interesting theory proposed by Reddit user hahajustburn, which states the following:

Y’all think Gege reused this idea into Jujutsu Kaisen?

I’ve always thought that Sukuna’s technique involved some sort of treasury because of the assortment of weapon-like attacks, like with the slashing and cutting compared to knives and then the flame arrows and bow.

Then I reread No. 9 again and just noticed a similarity.

Gege kind of (maybe) reused the design of Mahito’s ultimate form from another one shot of theirs, so maybe they reused this concept of boxes storing weapons too?

But I’m likely to be wrong maybe.

Also, does anyone know what that “fugue” means? All that came up on google where musical terms.

Edit: the fifth picture doesn’t seem to appear on my phone, can you guys see it? If not I’ll edit it.


In case you don’t know, “No.9” is a one-shot by Gege Akutami that was published in 2015. It s not similar to Jujutsu Kaisen, so there is no direct relation, but the character there also used a “Cublicle” technique, or the “Fugue,” which let him summon various weapons he could not normally use from a box-like storage.

Sounds familiar? Well, we don’t blame you, as it sounds very similar to the technique used in “No.9”. The technique is associated with the name “Fugue,” and seeing how Sukuna’s activation command is Fuuga (“Open!” in English), it certainly makes sense that the theory proposed this.

Long story short, we don’t know if this theory is true or not, seeing how Sukuna’s ■ has yet to be explained. From what we’ve seen, there are many similarities and if it is true that Akutami modeled ■ on the “Fugue” technique, we can expect big things to come from Sukuna if Akutami bothered enough to still write a good and coherent story for the end of Jujutsu Kaisen.


Jujutsu Kaisen: Did Sukuna Tame Mahoraga? Here Is What Happened!

The technique from “No.9” allowed the character to use some new and unexpected weapons, and if Sukuna’s ■ works similarly, we can expect very powerful and diverse attacks from him in the future, although it remains to be seen whether anyone will be able to stand up to him in his current state, but that is topic for a different article. In here, we have presented and explained a theory surrounding the origins of Sukuna’s enigmatic ■ technique.
