What is yujis domain expansion?

Yuji Itadori's Domain Expansion, Self-Embodiment of Perfection (無為転変, Mu'i Tenpen), is a unique and powerful technique in Jujutsu Kaisen. Unlike most Domain Expansions which rely on manipulating the environment, Yuji's focuses on manipulating himself.

Here's what we know:

• Nature: It's less about trapping opponents in a physical space and more about drastically amplifying Yuji's physical abilities and cursed energy within a limited area, essentially making him overwhelmingly strong within its confines. The area itself doesn't drastically change visually; instead, the effect is felt through the overwhelming power Yuji displays.

• Mechanism: The Domain Expansion works by boosting his physical attributes to superhuman levels – speed, strength, durability – all powered by Sukuna's immense cursed energy. He effectively becomes a living weapon, overwhelming opponents with raw power. It's less about intricate techniques and more about brute force and overwhelming pressure.

• Limitations: Yuji's control over this Domain Expansion is still developing and incomplete due to his lack of experience and the chaotic nature of the power he wields. It requires a significant amount of cursed energy to activate, meaning he can't use it for extended periods or repeatedly. The expansion itself isn't infinite and has an undefined range. Further, the user's physical condition significantly impacts the domain's effectiveness.

• In-universe Comparisons: It's distinctly different from other Domain Expansions seen in the series. Most Domains create elaborate traps and environments, while Yuji's is far more focused on maximizing his own offensive capabilities. It's less about strategy and more about sheer power.

• Incomplete Nature: Because he's not fully in control, the precise nature and boundaries of the Domain are still somewhat mysterious. We've seen glimpses of its capabilities, but its full potential remains largely unexplored.

In essence, Yuji's Domain Expansion is a raw display of overwhelming power centered around his own body, rather than a carefully crafted and controlled environment. It's a reflection of both his inherent strength and the chaotic power he wields from Sukuna's cursed energy.
