However, as society began to mature mentally, people began to search for "individuality" within controllable limits.

You make it sound so magical. Like we're time travelers or something.

Today, even if society is regulated, individual expression blooms brilliantly in the streets.

Changing rules, rituals, and value systems.

Through this alternate space-time, right now we are connected to a metropolis of the past.

What would you say we're trying to find when we open doors into other worlds?

Recreations of a culture(fantasy) we no longer have, right?

Rules and constants exist to define the phase we exist in, to set its boundaries.

And through certain rituals and ceremonies, we mold that space-time itself into a different world.

We really have a bad habit of grave-robbing, don't we?

Just for a moment, an imitation space-time is created, and another world is summoned.
