What is this?

[Edutyn]

The world is based on the delusions of each character trapped by B.

The world changes based on the character's delusion in his stage

1° stage is a temple (C)
2° stage is a ruin (D)
3° stage is a burning place (E)

Each stage is based on the concept that each character has of himself (C being a goddess, D being Jet Black Wings)

Or even each world/scenario is based on the personality of each character (E has an athletic, lively, and energetic personality, making its stage a place on fire where exercise is predominant.)

At the same time, each scenario has unique enemies.

And then threatens to erase everything as an illusion.

What ability would it be?

Maybe limited subjective reality?

I don’t think the word concept matters, since it’s being used as a synonym for notion rather than under the context of any philosophical idea.
