Unlimited Void in kanji letters
Gojo’s domain expansion technique, Unlimited Void says MURYOKUSHO in Japanese.
Here’s the kanji letters for it!
MU = nothing
RYO = amount, quantity
KU = empty
SHO = place, to put oneself in a certain place
The whole word can be interpreted as “a place with nothing” or “void space”. It’s originally a Buddhism word to express a process of enlightenment. It stands for a status that you are freed from any physical feelings and realize the infinity of the space.
How does the domain expansion work?
Muryokusho is a technique to force endless perception and transmission to the opponent. I think the English name “Unlimited Void” is a free translation.
The effect of the Unlimited void is explained in the Jujutsu Kaisen comic vol.2.
Do you know the Japanese word chain game called “Shiritori”? When someone says a word, you need to say the next word that starts from the last letter of the mentioned word. For example, if the first word was Apple, you’ll think up Egg for the second word.
In normal conditions, information flows in order like the Shiritori game. But in the Unlimited Void domain, the first A is repeated endlessly and never ends.
It may be like a brain is buggy. The one who got into the Unlimited Void ends up being crocked.
