Who Is The Traitor Or Mole In Jujutsu Kaisen?

WARNING: The following article contains major manga spoilers. Proceed at your discretion!

The Jujutsu Kaisen world is extremely unpredictable. The lives of the shamans are always on the lines, whether they are students or special grades.

These shamans have mortal enemies called cursed spirits, but sometimes the bigger enemies lie among people themselves.

Ever since Itadori Yuji’s story started, it seemed like the Jujutsu Kaisen’s villains knew too much. Of course, Geto leading them was a factor, but there are intricacies that no villain should have known.

They knew about the Jujutsu High College’s inside-outs, Itadori Yuuji, and even Gojo Satoru. There was surely something suspicious going on, and even Gojo realized it.

Previously (Jujutsu Kaisen 0) too, the villains knew everything about Tengen-sama‘s star vessel, Geto-Gojo duo’s movements, and penetrated the Tokyo High’s grounds.

They had found ways to get close enough to render Gojo Satoru unable to fight.

When the curses attacked the Kyoto Sister School Exchange Event, Gojo’s hunch was confirmed. There was definitely a traitor amongst them, if not multiple.

Gojo shared his concern with Utahime and asked her to investigate the Kyoto school.

Her findings were unexpected as one traitor was found out. Who was it? Before that:

Mechamaru revealed to be a traitor

After a thorough investigation by Utahime, she identifies the identity of one traitor. She tells Gojo that Mechamaru or Kokichi Muta, a second-year at Kyoto Jujutsu High, is the traitor.

We know that Kokichi’s actual body is elsewhere while he controls a cursed corpse, Mechamaru.

His ability is wide-range that can cover the entire nation due to Heavenly Restriction. So, he controlled small discs by cursed energy to spy on the schools’ activities without drawing attention.

But why did he turn a traitor?

In his fight against Panda, Kokichi reveals that his body is in an abysmal state. His skin is sensitive to even moonlight while his 3/4 limbs dysfunctional, rendering him wrapped in bandages.

Under such a pitiful state, he resented that he could not have a future outside jujutsu.

His frustration and anger regarding his abnormal body were pent-up for so long that he agreed to be the traitor.

Mahito and Geto promised Kokichi a normal body by Idle Transfiguration in exchange for cooperation and information. They also created a binding vow with him, sealing the deal.

After this vow, even if Kokichi did not want to deceive his people anymore, he couldn’t go against the vow.

Even with the identity of one traitor known, before going after him, Utahime reveals another important piece of information. There is another mole besides Kokichi amongst the Jujutsu sorcerers.

Who is the Second traitor?

According to Utahime, the second mole, unlike Kokichi, is someone ranked higher than even the principals who is cooperating with the curses.

This piece of information, however, is too vague for Utahime to do anything. It is also dangerous to point fingers at shamans who have a significant presence in the Jujutsu world.

And if they are willing to go as far as colluding with curses, they are sure to take immediate and fatal action to suppress people like Utahime.

Second traitor

In chapter 62, Geto Suguru was informed by someone about Eso and Kechizu’s death. This info surprisingly came to him on his phone.

We had initially assumed that this was the work of the second traitor.

But in chapter 80, this too was attributed to Mechamaru. So, we currently have very little info to go one about who the second traitor could be.

Note that Utahime says there are two or more people who are feeding info to the curse user.

However, we can maybe narrow down the list of suspects for the second traitor, or atleast someone who is working in tandem with the higher up.

Is Shoko Ieiri the traitor?

Was it a coincidence that Kechizu and Eso ended up appearing under the Yasohachi bridge to retrieve Sukuna’s finger at the same time that Yuji and the others appeared to exorcise the curse?

The mission details were probably leaked beforehand. And the only people who were aware of these details are the ones at Tokyo Jujutsu high.

In a side story that covered a day from Ijichi’s life, we see that he was fussing over the mission involving the curse at Yasohachi bridge.

He discusses this with Shoko and Gojo during drinks (well not in detail, but Shoko is aware of it). Other than Shoko & Ijichi, Arata also knew the details of the mission.

It seems beyond Ijichi to be a traitor. The same goes with Nitta (she was on the mission). Considering that Gojo was the prime target of the opponent, he can be ignored comfortably too.

So, the only person left, by the process of elimination is Ieiri. She becomes a prime suspect when you consider she did not dispose off Geto’s body.

Now, we know that Shoko is not a higher up. Instead, her role could be that of feeding information to them.

Could Shoko actually be up to something sinister? Or is she forcefully being put in a situation like that?

Anyways, if she in cahoots with one of the higher-ups who is the traitor, it would explain why she was not suspended or chased to the ends of the world like Yaga or Gojo for her involvement in the Shibuya incident (not disposing Geto’s body when she had the chance).

We have a few more speculations for people who could have been feeding information to the higher-ups; let’s take a loot at them!

Is Mei Mei the traitor?

A lot of people in the fandom have speculated Mei Mei to be the traitor. And when you Google about the traitor from Jujutsu Kaisen, you get the answer as her too.

Mei Mei and her absolute love for money is definitely a red flag. It is possible that she could betray the Jujutsu Society for money in the future.

As far as the incident in Shibuya is considered, did she betray the jujutsu sorcerers by leaving a violent fight in the middle? What is the extent of her betrayal? Did she sell everyone out?

But why would she put herself and Ui Ui in mortal danger if she had plans to make even more money from supporting the other side?

It seems that she was trying to save her skin and not “betraying” anyone per se.

As soon as Mei Mei realizes the Shibuya Incident’s global impact, she ducks out and sells all her stocks. She is selfish and cares about her life. But is it enough to make her a traitor?

We know far too little about Mei Mei except her few appearances starting from Jujutsu Kaisen 0. Also, does she have enough influence over the schools to sway a near war?

Is Yuki Tsukumo the traitor?

Everyone’s favorite special grade shaman and Aoi Todo’s trainer is the next guess for the mole.

Yuki Tsukumo is infamous for planting ideas about an apocalypse in Geto’s mind.

While her affirmations might have given that last push Geto needed to go haywire, her actions do not seem to be going in that direction.

Yuki’s ideologies are erratic, and she does not fit in the Jujutsu society. However, she wants to treat the cause of cursed spirits oppositely as Geto.

Before the recent chapters, Yuki did seem extremely suspicious.

The cover for chapter 56 even placed her next to Sukuna, making it seem like she will betray the community.

However, in the Shibuya Incident, she opposes Geto’s idea of optimizing cursed energy for a curse-free world.

Yuki Tsumuko

She is usually neutral about shamans’ affairs but is she sinister enough to pull the strings behind this act? And the fight is a ruse?

It seems not.

In the latest chapters, Yuki has aligned herself with Yuji and others in order to fight against Geto. So this should eliminate her from the list of suspects, atleast for now!

Yuki is just a misfit. It seems like she is working for the greater good of humanity behind the scenes. But with Jujutsu Kaisen, you never know!

I believe there are still a lot of characters we have to meet in the Jujutsu Kaisen world. Specifically, the “old people” Gojo despises.

For all we know, the mole is someone we haven’t seen yet.

Who do you think the second mole is? Who could the higher-up be? Are the heads of the Jujutsu families involved in this mess? And just what would be their goals?
