別次元

意味

Another dimension — someone operating on a completely different level from everyone else.

Describes someone whose skill, beauty, or presence is so far above the norm that they seem to exist in a different dimension entirely. Used when the gap between this person and everyone else is not just big but feels almost metaphysical. Popular in sports, entertainment, and fan culture for top-tier performers.
