Construction of an artificial island is disrupted by an unexplained phenomenon known as "burning sea". Masamichi Haru is injured by burning sea during a test of early Meta-Real technology, leaving him comatose for fifty years. Now elderly and wheelchair-bound, he still hopes to solve the mystery of burning sea. His friend Eichiro Kushima now hopes to use the Meta-Real, also known as the Metal, to research the burning sea phenomenon.

Haru has become an official investigator and is asked to dive into the Metal to rescue the consciousness of an Artificial Island shareholder who has experienced braindown.

Following the success of weather particle experimentation, the Secretary-General and Jeni En want to install weather particle plants as soon as possible. Kushima is opposed to the plan, suspecting that the weather particles will cause complications that threaten the Artificial Island. Meanwhile, Sota goes on a date with Holon.
