Matsuyama, leader of the Kanto Cyber Imaginary Number Group, plans to light up a gigantic adult entertainment building with excess electricity in order to take over the land owned by the rival Nakahara-gumi. But its leader, Nakahara, has a reason to refuse it. His beloved Arika suffers from a rare disease where her body spasms to neon light - fatal if untreated.
