Chapter 66

In Jujutsu Kaisen Manga Chapter 66, Yaga gives Gojo and Geto a serious mission.
They must protect and escort the Star Plasma Vessel to Master Tengen.
As they joke about Yaga’s promotion, the mood slowly turns serious.
Geto asks if this mission is to reset Tengen’s cursed technique.
Yaga explains that Tengen is immortal, but their body still ages like a normal person.
If Tengen does not merge with a Star Plasma Vessel every 500 years, they may evolve into something inhuman.
Such a change could make their power impossible to control.
The merger keeps Tengen stable and protects the barriers that shield the jujutsu world.
Gojo and Geto accept the weight of their task.
