Yuji is the Protagonist of Jujutsu Kaisen.
However, there are still many things about him that have not been revealed.
Why is his physical ability so high?
Is his mother really Kenjaku?
In the meantime, I would like to introduce a theory about Yuji’s true identity.

Yuji must have a close relationship with “Ainu”.
I will tell it to you all!!
Ainu’s an original tribe in Hokkaido.
Hokkaido is a place located in the northern part of Japan.

Hokkaido is a Blue area.
Yaga talked about “Ainu Jujutsu Company” too.

Ainu(Hokkaido) is a very important part of Jujutsu Kaisen.
Then about Yuji’s true identity.
Ainu has a famous epic poem(yukar).
There is a legendary sword.
The name is Kutune Shirka (“Itadori-maru(虎杖丸)” in Japanese).
It’s the same as Yuji’s family name(Itadori/虎杖).
This can’t be a coincidence, can it?
・About “Itadori-maru”
It is said that “Itadori-maru” has 4 spirits inside.
・Wolf
・Fox
・2 Dragons
They have something in common with Yuji’s abilities!!

・Wolf → Physical ability
・Fox → Memory that doesn’t exist
・2 dragons → Sugawara no Michizane
I’ll explain them one by one!!!
・Wolf → Physical ability
Yuji has extraordinary physical strength…
This has something to do with the wolf.
Wolves can run 50m in 3 seconds.
Yuji can also run 50m in 3 seconds, according to Ch.1.

Also, look at this scene in Ch.132.

Yuji is described as a wolf.
This can’t be a coincidence.
Gege is implying that Yuji is a wolf!!
・Fox → Memory that doesn’t exist
Yuji’s ability to show memories that don’t exist.
This seems to be related to the Fox.
It is said that foxes bewitch people in Japan.
Fox is believed to deceive people.
And Yuji can show people memories that don’t exist.
Choso saw memories that don’t exist because they are brothers.
But what about Todo?
Yuji must have shown it to him somehow.
This means that Yuji has the same kind of ability as Fox!!

・2 Dragons → Sugawara no Michizane
It is said that they are incarnations of the Thunder God.
And one person is also believed to be Thunder God.
That person is Sugawara no Michizane!!
He is the ancestor of Gojo and Okkotsu…

This means Yuji may have a connection with him.
・There are other connections to ”Ainu(Hokkaido)”.
First, look at this illustration.

This is the poster in Jump GIGA.
I want you to pay attention to Yuji’s hand.
He has a sword in his hand.
Wow, I guess this is “Itadori-maru”!!?
This can’t be a coincidence, can it?
And in chapter 146, Hokkaido was mentioned.

It seems that this is a special place.
In the past, the people of Ainu used prophecy and divination to prevent calamities.
This seems to be strongly related to “Curse”.
This may become an important factor in the future.
I tweeted another piece of information about “Hokkaido”.
Gege Akutami likes to quote Copy from Real ads.
・Challenged Land
→ Hokkaido’s Catchphrase
・Everything’s because of the Curse
→ JR’s catchphraseHe has very good sense😂#JujutsuKaisen#呪術廻戦 pic.twitter.com/EaBto1fQ0u

Anyway, I want you to keep in mind about “Ainu(Hokkaido)”.
