Another question.

About the Avatars, when you fight them and they say "Are you ready, you who is one yet many?". What exactly are they referring to, and what is the text in Japanese? Because it sounds like they are breaking the fourth wall for a second to acknowledge players fought these fights in groups even though every cutscene plays it like we are soloing.

The full intro says:

"...Who interrupts my slumber?
Was I dreaming for but an instant, or an eternity?
The radiance that illuminates all, lost...
Which is the real world, and which is the dream? Am I...?

But enough...
Wager your life to prove your skill.
Let us see if you can provide me with a moment of amusement.

Are you ready, you who is one yet many?"
