S1·E1 Underwater Island Drive

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.
