How Was Mechamaru Talking to Yuji Even After Death?

Kokichi had a clever plan set up before he died. He made special cursed dolls using his technique and Heavenly Restriction. These dolls were like pieces of his soul, powered by his stored cursed energy.

In Jujutsu Kaisen season 2, we can see Mechamaru still communicating with Yuji Itadori, even though Kokichi Muta, the person behind Mechamaru, had died. This mysterious ability to speak wasn’t just a plot convenience – it was the result of careful planning and Kokichi’s unique abilities.

Kokichi’s Technique and Heavenly Restriction

To understand how this was possible, we need to look at Kokichi’s jujutsu technique and his Heavenly Restriction:

1. Jujutsu Technique: Kokichi’s technique likely involved collecting and storing cursed energy for later use. This allowed him to create reserves of power that could outlast his physical body.
2. Heavenly Restriction: This condition severely limited Kokichi’s physical abilities but granted him an enormous amount of cursed energy with an extremely wide range.

The Cursed Doll Plan

Before his death, Kokichi set up an intricate plan:

1. He created what were essentially cursed dolls, similar to Panda or the ones Yaga makes.
2. These dolls contained pieces of Kokichi’s soul and cursed energy.
3. He placed three of these dolls in strategic locations:

• One with the Kyoto jujutsu team
• One with Yuji Itadori
• One to spy on Geto and the curses (though Mahito later destroyed this one)

The Activation Condition

Kokichi set a specific condition for these dolls to activate: they would become operational if Satoru Gojo was sealed. This was a smart move, as Gojo’s sealing would signal a major crisis in the jujutsu world.

How the Communication Worked

When Mechamaru was talking to Yuji in season 2, it wasn’t the original Mechamaru puppet, but one of these special cursed dolls. Here’s how it functioned:

1. The doll contained a piece of Kokichi’s consciousness.
2. It was powered by the cursed energy Kokichi had stored before his death.
3. With Heavenly Restriction, the doll could communicate over vast distances.
4. The doll could think and react independently, using the fragment of Kokichi’s soul it contained.

Why This Matters in the Story

This posthumous communication served several important purposes:

1. Strategic Advantage: It allowed Kokichi to pass on crucial information even after his death.
2. Character Development: It showed the extent of Kokichi’s planning and dedication to the cause.
3. Plot Progression: It provided a way for the deceased Kokichi to still influence events.
4. World-building: It expanded on the possibilities of jujutsu techniques and cursed energy use.

Limitations and Drawbacks

This technique also had its limits:

1. Finite Energy: The dolls could only function until the stored cursed energy ran out.
2. Limited Interaction: They couldn’t physically intervene in situations, only communicate.
3. Vulnerability: As seen with the spy doll Mahito destroyed, they could be eliminated if discovered.

Conclusion

Mechamaru’s ability to talk to Yuji after Kokichi’s death showcases the complex and innovative use of cursed energy in Jujutsu Kaisen. It’s a testament to Kokichi’s intelligence and foresight, allowing him to contribute to the fight against curses even after his physical body was gone. This clever use of jujutsu techniques adds depth to the story, demonstrating that in this world, a sorcerer’s influence can extend beyond their lifetime.
