You know, I originally expected this world to be free of sin until...
Now.
Because, the walking dead all over the mountains and plains are the source of evil.
Human beings' endless greed drives their wisdom, and finally studies the 'evil'...
Presumably, the people who reaped the consequences must be very happy.
Superpower ≠ portable space.
Personally, I think the end of the world with portable space does not make any sense.
