The artificial island is severely hit by the burning sea phenomenon and by a following unidentified impact wave. The violent impact causes a power outage on the entire island and the life-support devices in the hospital have stopped operating. In order to resolve the crisis, Haru's young assistant Minamo runs on the abandoned monorail track heading toward the electrical substation. Meanwhile, Haru plunges into the Meta-Real Network. Inside this new environment, he feels a new "sea," and begins to utilize his ability to a completely different kind of diving, this time inside the human brain.
