Sky Wall

The Skywall is a mysterious structure that materialized 10 years ago in 2007 after the Pandora Box was activated by a human attempting to steal it pressing his hand on the box. Its materialization caused several people in proximity of it to float helplessly into the air and for the entire country of Japan to be split into three parts.

Based on events 10 years later, it seemingly could not be destroyed or torn down as the Pandora Box that is powering it generates an enormous amount of an unknown alien energy far greater than any atomic energy source on Earth.
