Why does Gojo wear a blindfold?

Gojo Satoru, one of the main characters in the anime and manga series Jujutsu Kaisen, wears a blindfold as a way to limit his powers.

Gojo's Jujutsu technique is called "Limitless," which allows him to manipulate space at will. He can control the shape and size of objects and space around him. However, his powers are so immense that they can be dangerous if not controlled. His ability is so powerful that it can cause severe physical and psychological damage to himself and those around him.

To prevent himself from unintentionally using his powers, Gojo wears a black blindfold that covers his eyes, which helps limit his vision and thus the amount of space he can manipulate. By wearing the blindfold, Gojo can control his powers and ensure that he doesn't accidentally harm others.

It's also worth noting that Gojo's blindfold has become somewhat of a trademark for him, and it has become an iconic part of his appearance in the series.
